Many construction companies still employ their workers without caring about the implementation of accident risks, by paying attention to work safety, it is expected that the performance of the workers will increase. This study aims to analyze the influence of occupational safety and health factors and worker motivation factors that affect the performance of workers in residential construction projects. The relationship between occupational safety and health, worker motivation and worker performance will be made in a path diagram model, and analyzed using SEM-PLS with a sample of 72 respondents. The results of the study found that the dominant factors in occupational safety and health are worker health monitoring, emergencies, personnel selection and placement, and hazard inspections. Meanwhile, the dominant factors that influence the motivation of craftsmen are wages, timely payment, and continuity (job security). In residential construction projects, occupational safety and health have a significant positive effect (P <0.0.5) on the motivation of craftsmen, in addition, worker motivation also has a significant positive effect on worker performance. In addition, occupational safety and health also have a significant positive effect directly on worker performance.

Full textAbstract:
Co-worker safety support has been given prominence in manufacturing and transportation field for its positive effect on individual workers’ safety; however, there is little evidence to show if such supporting role of co-workers is significant in improving project-level safety performance in construction workplace. This study adopts agent-based modeling (ABM) to understand the effectiveness of two distinct co-worker-safety-support actions on the safety performance of a construction project. Based on the risk theory, the ABM model simulates a construction site where worker agents reinforce steel bars with the likelihood of suffering crane-related incidents. The results indicate that both co-worker-support actions can significantly reduce the occurrence of nonfatal incidents but shows little influence in fatal incidents, and in reducing high-severity incidents, the action of warning peers to leave the hazardous area has the same effectiveness as reminding peers to wear Personal Protective Equipment. The present study provides a fresh insight into the safety-related role of co-workers: not only reveals how the local-level effects of co-workers’ safety assistance emerge the system-level consequences, but demonstrates the effectiveness of specific peer-support actions on three levels of construction safety performance, and thereby extends our existing body of knowledge on co-worker safety support in the construction field.

The performance of workers is one part of being able to develop a business. Not only demanding from the side of workers, companies also need to pay attention to work facilities to improve worker performance. Occupational Health and Safety is one part of the labor law. Every employer organization is required to implement Occupational Health and Safety in the implementation of work. Occupational Health and Safety is an important element to build worker performance. In addition, the perceived workload will determine the performance of workers. This study aims to determine the role of Occupational Health and Safety and workload on the performance of construction workers. This study uses 89 respondents who are construction workers. Data were obtained using a questionnaire which was distributed to the research sample. This study uses regression analysis. The results showed that Occupational Health and Safety had a significant influence on the formation of worker performance. Furthermore, the performance of workers is also known to be significantly influenced by workload. The two variables, namely Occupational Health and Safety and workload, are known to have a significant influence together on the formation of worker performance.

Full textAbstract:
The increasing sophistication and complexity of construction technology have also increased workers’ physical risk and psychological stress. This study examined the relationships between health risks, work motivation, and productivity as perceived by construction workers. A hypothetical model of worker perceptions, and the psychological factors influencing these perceptions, was developed. A total of 324 construction workers at a Japanese construction company participated in the study and were divided into two groups: younger (45 years of age and below) and older adults (46 years of age and above). Data were collected using a questionnaire. The differences between the age groups were analyzed with regard to their perceptions of health risks, motivation, work skills, and productivity. Both younger and older workers were affected by intrinsic motivations and extrinsic motivations, but the effect of these motivations on work performance differed depending on age. Higher health risks are anticipated to affect the work motivation and productivity perceptions of older workers. The proposed model and findings of this study contribute to understanding worker motivations and have important implications for labor management of construction projects. By addressing construction workers’ intrinsic (e.g., interest) and extrinsic (e.g., reward) motivations, it is possible to sustainably improve project productivity.

Full textAbstract:
The drilling rig construction project has the characteristic that its workers experience the impact of limited time and budget pressures in the planning and execution of activities, most of which are carried out by skilled human workers who are temporary in nature who migrate from one place to another and are heavily influenced by weather conditions and The surrounding environment is a few special characteristics that distinguish drilling rig activity projects in well drilling from construction projects in other industries. The forming factors of OSH culture have an effect on improving the OSH performance of workers on drilling rig activity projects and OSH culture at PT X. This research was conducted to identify and analyze the factors forming OSH culture which influence the OSH performance of workers, especially on drilling rig activity projects, as well as analyzing the influence of the factors forming the OSH culture on the OSH performance of the drilling rig activity project workers. The independent variables: Worker Commitment to K3 (X1), Compliance with K3 Regulations and Procedures (X2), Worker Communication in K3 (X3), Worker Competence in K3 (X4), Worker Involvement in K3 (X5), Worker Environment (X6), While the dependent is the K3 Performance of Drilling Activity Project Workers (Y). Data analysis in this study used descriptive statistical analysis and multivariate analysis with the Smart Partial Least Square 3 (SmartPLS 3) approach. The results of the analysis of the behavior of the respondents were male, mostly aged 36-45 years, had a Bachelor's degree, and had worked for more than 6 months and the results of the analysis of the respondents' perceptions of each variable obtained an average value calculated between 4.18 – 4.34. The results of the Smart Partial Least Square 3 analysis show that the independent variables consisting of workers' commitment to OHS (X1), Compliance with K3 regulations and procedures (X2), and Worker Involvement in OHS (X5) have a significant and positive effect on the dependent variable OHS Performance of Project Workers Drilling Rig Activities (Y).

Full textAbstract:
The workers in the PT.X construction project have high work hazards and risks, especially in the face of the COVID-19 pandemic. Because construction projects are projects that must continue, the risk of workers being exposed to COVID-19 is high. If there are workers who are exposed to COVID-19, then directly or indirectly the work carried out by the worker will be replaced/backed up by his co-workers. So this can cause fatigue in construction workers. Work fatigue is one of the causes of work accidents. Fatigue can reduce the concentration of workers, reduce decision-making abilities, reduce work/muscle strength, communication skills, productivity, alertness and physical and mental performance and reduce work motivation. The purpose of this study was to determine the effect of Covid-19 on worker fatigue in the Company. The population in this study were 353 workers at PT.X with inclusion criteria being workers who worked overtime and who replaced their colleagues' work in the last 1 month and exclusion criteria were workers who never worked overtime and replaced their co-workers as many as 55 workers were analyzed univariately and bivariately with simple linear regression analysis model. The results showed that the COVID-19 pandemic had an effect on fatigue among workers at PT X. A significant variable was the age of workers, who worked > 8 hours a day, length of work > 5 years and less rest time, causing fatigue to worker.

Many construction organizations still employ workers without regard to the application of accident risk, although a focus on safety is predicted to improve worker performance. This study aims to examine the effect of occupational safety and health and incentive factors on worker performance in housing construction projects. This study used a quantitative approach and was tested using the SEM-PLS method with a sample of 72 respondents. The results showed that well-implemented occupational safety and health significantly improved worker performance, by reducing the risk of injury and improving worker welfare. In addition, high work motivation plays a role in increasing project productivity and efficiency. Emphasis on safety, health, and work motivation was shown to have a positive impact on achieving better project performance. The implications of this research provide important insights for construction managers and policy makers in optimizing project success through the implementation of effective safety protocols, wellness programs, and appropriate motivation strategies. Thus, this study highlights the importance of integrating occupational safety and motivation as key factors in achieving superior project performance.

Full textAbstract:
Background: Work-related accidents in construction are not only the cause of significant human suffering and loss; they are also complex phenomena involving multiple risk factors and stakeholders. Accordingly, numerous protocols and regulations have been developed to prevent construction work-related injuries in various settings. However, a specific accident prevention program has not been thoroughly investigated for construction workers in onshore oil and gas pipeline construction in Thailand. This study aims to develop and assess the effectiveness of an accident prevention program among onshore pipeline construction workers in Thailand. Methodology: Mixed-methods research was conducted from March 2022 to March 2023 among 577 workers and 30 stakeholders in construction projects. The data were collected by a self-administered questionnaire and brainstorming. Multiple linear regression analyses, paired samples t-test, Safe-T-Score (STS), and content analysis were applied to analyze the data. Results: The work-related accident prevention program, consisting of six steps with five proactive activities, effectively improved worker health and safety performance (P < 0.001). When compared to past performance, STS was less than -2 (STS = -2.18), which indicates an improved accident record. Worker health and safety performance was associated with poor environment (β = -0.146; P = 0.003), unsafe worker behaviors (β = -0.123; P = 0.026), unsafe workplace conditions (β = -0.466; P <0.001), and organizational psychology factors (β = 0.272; P < 0.001). Conclusions: We recommend extending this program to other construction workers in related contexts to improve accident prevention and promote safe work practices.

Full textAbstract:
This thesis addresses the issue of measuring worker engagement in health and safety management in the construction industry. The concept of worker engagement has become important due to the lack of effectiveness of regulation in reducing accidents and incidents in this most risky of industrial environments. It is believed that by involving workers at all levels in the project organisation in health and safety matters and their resolution, the rate of injury can be better controlled. The study adapted and contextualised an existing management tool created by the author, based on the proposition that there are e accepted dimensions that describe worker engagement in health and safety in construction and that they can be measured.

Optimum construction worker (CW) performance is required to achieve project delivery within project parameters. It is not always the case as CWs are regularly exposed to hazards, involved in accidents, their productivity is poor, they suffer from ill health, suffer from work-related musculoskeletal disorders (WMSDs) and contractors lack resources to allocate towards H&S. However, the lack or the absence of health and safety (H&S) measures, which the aforementioned depend on, has a negative impact on workers’ performance. Two descriptive surveys were conducted among professional construction project managers (CPMs) registered with the South African Council for Project and Construction Management Professions (SACPCMP) and general contractors (GCs) registered with the East Cape Master Builders Association (ECMBA). Interviews were also conducted with CPMs registered with the SACPCMP residing in the Nelson Mandela Bay metropolitan area. The salient findings include: • Accidents, which occur on construction sites, impact workers’ performance; • Inadequate H&S implementation affects both CW skills and motivation, which in turn affects their performance; • Poor constructability is relevant to H&S and CWs’ skills; • Provision and maintenance of welfare facilities are commonly inadequate and affect workers’ performance, and • Projects do not benefit from the adequate financial provision for H&S. It was concluded that exposure to hazards, poor site conditions, inadequate provision of welfare facilities, WMSDs, and insufficient financial provision for H&S affect workers’ performance by either incapacitating or demotivating them. Recommendations include : CPMs should make better use of their influence on clients; they should improve communication channels between project stakeholders; legislators need to raise awareness regarding H&S and worker welfare, and training and education institutions need to empower workers and professionals with H&S knowledge.

Full textAbstract:
Given the large economic and social costs of work-related accidents and injuries, it is not surprising that organisations strive to reduce them; this creates a need to improve the safety performance of the whole construction industry. Health and Safety statistics in general appear to suggest a levelling off of safety performance across the construction industry as a whole and this implies that improving safety beyond the current level of attainment calls for a radical look at how safety is addressed by the industry. Such a radical approach needs to explore alternatives to current practices in safety improvement. Although it is acknowledged that human factors are involved in 80-90% of work-related accidents and incidents, the focus of safety research in recent years still addresses only organisational and environmental factors, rather than variables at the level of the individual. Occupational personality models suggest that the ability to understand, predict and control incidents could minimize their potential transition into accidents. The safety behaviour of the individual worker forms part of such occupational personality modelling. Understanding the safety behaviour of construction workers should provide opportunities for improvement beyond traditional practices in the quest to improve safety management. The study on which this thesis is based aimed to develop a conceptual framework for improving safety performance on sites. This was achieved by exploring, on the one hand, the relationship between the personality traits of individual workers and their safety behaviour (safety participation, safety compliance and safety motivation), and incident rates on the other. The data for the analysis was drawn from multi-cultural construction workers in Saudi Arabia. The emergence of the Big Five personality model has been widely accepted as a valid and reasonably generalisable taxonomy for personality structure and has been used by numerous researchers as a framework to explore the criterion-related validity of personality in relation to job performance. This study employed the Big Five categorisation of traits to explore the relationship between fundamental dimensions of personality and potential for involvement in accidents and incidents. The principal findings from the study showed a very good level of acceptance by practitioners in Saudi Arabia for the conceptual framework developed for managing safety behaviour. The study also established that some personality traits moderated the effects of safety behaviour for incident rates. In addition, the analysis revealed that individual workers characterised by conscientiousness and openness are least likely to experience incidents, and consequently, accidents and injuries at work. However, individuals characterised by high extraversion, neuroticism and low agreeableness are more likely to be v involved in incidents, and potentially, accidents and injuries. These important findings have significant ramifications for the way safety development and training for construction workers should be addressed in the future. Recommendations from the study culminated in the development of a conceptual framework for improving safety performance which aimed to minimize incidents attributable to the worker. The framework relies on the attitudes and behaviours of employees in proposing mitigation strategies for the construction industry.

Full textAbstract:
Stress och dess påverkan på människans arbetsprestationer är väldokumenterade sedan tidigare. Hur den påverkar manliga byggnadsarbetare specifikt under en pandemi är däremot okänt och har därför valts att i denna studie närmare undersökas. Datainsamlingen genomfördes med hjälp av semistrukturerade intervjuer med åtta byggnadsarbetare. Den insamlade datan analyserades därefter genom en tematisk analysprocess där materialet slutligen kom att delas in i sex teman. Temana benämndes: oförutsedda händelser, att tillfredsställa kundens krav, oro över att bli smittad, ökad arbetsbelastning, minskad noggrannhet och säkerhet samt försening av tidsplan. De fyra förstnämnda temana var de stressorer som deltagarna upplevde och de två sistnämnda temana var hur deltagarna upplevde att stressorerna påverkade deras arbetsprestationer. Varje funnet tema i resultatet presenterades av citat ifrån flera deltagare i studien. Den slutsats som kan dras är att byggnadsbranschen hade gynnats av att förbättra byggnadsarbetares psykosociala arbetsmiljö genom exempelvis ökat inflytande för att arbeta förebyggande mot byggnadsarbetares mentala ohälsa.

Full textAbstract:
The performance assessment done by objective measures have now been replaced with subjective measures. Within the context of this research<br>interdependencies between a construction company&rsquo<br>s &ldquo<br>resources and capabilities&rdquo<br>, &ldquo<br>project management capabilities&rdquo<br>, &ldquo<br>strategic decisions&rdquo<br>, &ldquo<br>strength of relationships with other parties&rdquo<br>and &ldquo<br>external factors&rdquo<br>with &ldquo<br>project performance&rdquo<br>and &ldquo<br>company performance&rdquo<br>were investigated from a resource based perspective which put forward intangible assets of the company. To achieve the objectives, a questionnaire survey was administered to
73 Turkish contractors and the data obtained from 354 projects that were held during the last five years were analyzed using structural equation modeling (SEM). It was hypothesized in this study that construction company performance is influenced by the resources and capabilities within the company, the long-term and short-term strategies adopted by the company, the strength of the relationships of the company with other parties involved in construction projects, external factors and project management competencies. A structural equation model was set up to measure the seven latent variables through their constituent variables and to see if the hypothesized relationships exist. Based on the findings of this study, it can be concluded that, this research has introduced a method to measure performance both in subjective (qualitative) and the objective (quantitative) terms. The strong path coefficients between the constructs of the model are an indication that, after decades in pursuit of finding ways to improve the performance of construction companies, subjective dimensions of performance have proven to be as effective as the traditional objective dimensions.

Full textAbstract:
International joint ventures (IJVs) have become popular because of their importance as a strategic alternative in global competition. Construction companies consider IJVs as a vehicle to enter new markets and exploit business opportunities. Being a special type of strategic alliance, IJVs offer partnering companies to combine the distinctive competencies and the complementary resources. Despite the benefits associated with IJVs, such entities are very difficult to manage mainly due to their inherent complexity, involving a mixture of different cultures, managerial systems, philosophies, and attitudes. As a result of these difficulties, the failure rate of IJVs is generally high. Therefore, measurement of the performance of IJVs has been an important research topic for a few decades. However there is no consensus on an appropriate definition of the indicators and determinants of IJV performance in construction.
In this study, a framework is proposed to model the IJV performance in construction industry. A multi-dimensional performance measure is developed and determinants influencing the level of performance are defined. In this context, a questionnaire survey was administered to Turkish construction companies that have established IJVs with foreign partners. The validity of the proposed drivers and measures of performance is investigated and relationships between them are analyzed using the structural equation modeling technique.
The results point out the significance of the inter-partner fit and the quality of partner relations for a successful IJV operation. The findings of the study also suggest that project-related factors have a moderate influence on IJV performance. In a properly designed IJV structure, partners with compatible skills, resources, and cultures are found to maintain good relations and are expected to achieve greater IJV success.

Full textAbstract:
The aim of strategic group analysis is to find out if clusters of firms that have a similar strategic position exist within an industry or not. In this thesis, by using a conceptual framework that reflects the strategic context, contents and process of construction companies and utilising alternative clustering methods such as traditional cluster analysis, self-organizing maps, and fuzzy C-means technique, a strategic group analysis was conducted for the Turkish construction industry. Results demonstrate that there are three strategic groups among which significant performance differences exist. Self-organising maps provide a visual representation of group composition and help identification of hybrid structures. Fuzzy C-means technique reveals the membership degrees of a firm to each strategic group. It is recommended that real strategic group structure can only be identified by using alternative cluster analysis methods.
The positive effect of differentiation strategy on achieving competitive advantage is widely acknowledged in the literature and proved to be valid for the Turkish construction industry as a result of strategic group analysis. In this study, a framework is proposed to model the differentiation process in construction. The relationships between the modes and drivers of differentiation are analyzed by structural equation modeling. The results demonstrate that construction companies can either differentiate on quality or productivity. Project management related factors extensively influence productivity differentiation whereas they influence quality differentiation indirectly. Corporate management related factors only affect quality differentiation. Moreover, resources influence productivity differentiation directly whereas they have an indirect effect on quality differentiation.

Full textAbstract:
The monograph is devoted to improving the methods of directed and controlled regulation of the C — S — H-gel structure by varying the doses, sizes, physical and chemical characteristics of the surface, and the nanoparticles used. The authors have developed an additive that additionally contains a superplasticizer to reduce the water demand of the concrete mixture and stabilize the nanoparticles. The dependences of the strength growth of cement stone and structural heavy concrete on the components of the complex additive are revealed. Experimental confirmation of the mechanism of action of a combined nano—additive with a reduced consumption of nanoparticles on the structure of C — S - H-gel was obtained based on the results of the application of a set of methods. It is revealed that the use of a complex additive contributes to a proportional increase in the reduced modulus of elasticity, hardness, and mechanical characteristics of Portland cement stone and concrete. The study of the additive in the conditions of the construction site showed the prospects of its application for construction, ensuring a reduction in the cost of the technology of nanomodification of concrete relative to the effect of improving performance.
 For specialists of research, construction and design organizations dealing with the modification of concrete with nanomaterials, as well as for students, undergraduates, postgraduates, teachers who work on the problems of building materials science.

Full textAbstract:
The construction industry faces significant challenges, including a high prevalence of occupational incidents, often involving fires, explosions, and burn-related accidents due to worker non-compliance with safety protocols. Adherence to safety guidelines and proper utilization of safety equipment are critical to preventing such incidents and safeguarding workers in hazardous work environments. Consequently, a monitoring system tailored for construction safety during welding operations becomes imperative to mitigate the risk of fire accidents. This paper conducts a brief analysis of OSHA rules pertaining to welding work and introduces the iSafe Welding system, an advanced real-time safety monitoring and compliance enforcement solution designed specifically for construction site welding operations. Harnessing the real-time object detection algorithm YOLOv7 in conjunction with rule-based scene classification, the system excels in identifying potential safety violations. Rigorous evaluation, encompassing precision, recall, mean Average Precision (mAP), accuracy, and the F1-Score, sheds light on its strengths and areas for improvement. The system showcases robust performance in rule-based scene classification, achieving high accuracy, precision, and recall rates. Notably, the iSafe Welding system demonstrates a formidable potential for enhancing construction site safety and regulatory compliance. Ongoing enhancements, including dataset expansion and model refinement, underscore its commitment to real-world deployment and its strength in ensuring worker safety

Nowadays, despite the growing attention to indoor environmental quality and comfort, existing workplaces still often fail to meet employees’ expectations and needs, affecting their well-being and productivity. In order to improve management decisions, crucial insights can be provided by the timely correlation of objective workplace conditions, observed by sensors, and subjective workers’ feedback, collected through Ecological Momentary Assessment (EMA) method. This paper presents a prototypical Digital Twin for the assessment of workplace performance from an occupant-centric perspective, based on the integration of IoT, BIM and Semantic Web technologies. Following the definition of relevant use cases and requirements a layered system architecture is presented and the prototype implementation is discussed. For capturing the workplace’s environmental properties, a sensor network based on the Zigbee communication standard is proposed due to its data transmission efficiency. The measured data, converted in the lightweight MQTT protocol, are streamed to an InfluxDB time series database where they are stored along with the incoming workers’ feedback collected as survey responses with a dedicated web application. These time series data are queried and transported into a developed web platform for integrating BIM and RDF data within the standardized structure of Information Containers for linked Document Delivery (ICDDs). Inside this platform, the IFC model of the workplace, the measured data from the sensors, and the worker generated RDF data according to the WOMO ontology for occupant-centric workplace management are linked. The capabilities of the workplace Digital Twin prototype are finally demonstrated querying the linked heterogeneous data to fulfil workplace management tasks in a case study provided at the end of the paper

Full textAbstract:
The construction industry has long been recognized for its complex safety regulations, which are essential to ensure the well-being of on-site employees. However, navigating these regulations and ensuring compliance can be challenging due to the volume and complexity of the documents involved. This study proposes a novel approach to extracting information from construction safety documents utilizing Large Language Models (LLM), called CSQA, to provide real-time, precise answers to queries related to safety regulations. The approach comprises three modules: (1) the construction safety investigation module (CSI) collects safety regulations for building the information needed. By leveraging a collection of safety regulation PDFs, the system follows a process of text extraction, preprocessing, and global indexing for efficient search. (2) The safety condition identification module (SCI) retrieves the CSI database; after that, the LLM, with its extensive training, processes user queries, searches the indexed regulations, and retrieves pertinent information. (3) the safety information delivery (SID) would provide the answer to the user and incorporate a feedback mechanism to further refine system accuracy based on user responses. Preliminary evaluations reveal the system's superior performance over traditional search engines, owing to its ability to grasp query context and nuances. The CSQA presents a promising method for accessing safety regulations, with potential benefits including reduced non-compliance incidents, enhanced worker safety, and streamlined regulatory consultations in construction

Full textAbstract:
Previous efforts demonstrated the ability to achieve a 30% weight reduction for a MIL-DTL-27422D Phase I test cube construction with Protection Level A gunfire performance, using a lightweight 2-ply exoskeleton design to replace the 4-ply construction otherwise required to meet crash impact test requirements. An additional 20% reduction in weight was projected by replacing the natural gum rubber (NGR) used in conventional fuel bladder constructions with a lightweight formulation. This paper reviews the technical efforts executed to support the transition of the lightweight exoskeleton construction to the Apache AH-64 helicopter. The fuel bladders made with the lightweight sealant were 15.5% lighter for the AH-64 FWD fuel bladder and 13.2% lighter for the AFT. Additional weight savings based on the 2-ply exoskeleton construction was not realized as the existing AH-64 fuel bladders are already relatively lightweight constructions. The final AH-64 fuel bladders demonstrated the ability to be qualified to all MIL-DTL-27422E performance requirements; however, the program concluded without demonstrating Protection Level A gunfire performance. Importantly, there did not appear to be any discernable difference in the self-sealing performance of the fuel bladders made with the lightweight sealant and the constructions based on conventional NGR sealant. While additional work may be required to address this performance deficiency, there were several issues that were noted during the Phase II gunfire testing that should be reviewed and resolved prior to additional testing.

Abstract This paper updates previous editions of "The Paint and Coatings Cost and Selection Guide"1 published by the authors biennially through NACE since 1979. The Guide is designed to help coatings engineers, specifiers, and users to: (1) identify suitable paint and protective coating systems for specific industrial environments; (2) calculate current approximate installed costs and estimated service life for each; and (3) determine the most cost-effective systems, including economic justification. Costs for both new construction and maintenance painting are supplied, including typical maintenance repainting sequences and their composition. The effect of maintenance sequences on long-term costs and system performance are reviewed.

Abstract This paper updates “Updated Protective Coating Costs, Products, and Service Life”(1) on protective coating costing and selection co-authored by G. H. Brevoort, M. F. MeLampy and K. R. Shields. Beginning with this edition, data collection and publication will be co-authored by K. R. Shields, M. F. MeLampy and M. P. Reina. Designed to assist the coatings engineer or specifier in identifying suitable protective coating systems for specific industrial environments, this paper provides guidelines for calculating approximate installed costs, expected coating life for each identified system, and how to determine the most cost-effective systems. The effect of maintenance sequences on long-term costs and system performance is also reviewed. New features of this paper include life-cycle and material costs for hot dip galvanizing. Included in the paper are 1) most commonly used generic systems in typical industrial environments, 2) service life for each, 3) current material costs, and 4) current field and shop painting costs. Guidelines for developing long-term life-cycle costs, and number of paintings for the expected life of the structure are included. The basic elements of economic analysis and justification, and how to prepare a Present Value Analysis are also addressed. Worksheets and examples are provided to aid the reader in the proper use of the information.

Full textAbstract:
Abstract The long term performance of any coating system will be limited by the ability of the applicator to achieve the best combination of surface preparation, application, and curing. In oil and gas facility construction, sometimes the most appropriate coating system is not the best available technology, but rather the system that ensures the highest probability for success based on the environmental conditions during application. An example is presented in which a zinc rich epoxy coating provides clear advantages over the specified inorganic zinc silicate due to circumstances specific to the particular application.

Full textAbstract:
Abstract The Kentucky Center for Energy Research Laboratory is currently conducting research to identify wear and corrosion related problems in physical coal cleaning (PCC) plants. The purpose of this work is to establish a data base on materials performance in PCC plants, study the corrosivity/erosivity of various types of Kentucky coals in slurries, and determine wear/corrosion control procedures. This information can then be used to assist PCC operators in selecting suitable materials for their plants. Field work is underway at the Tennessee Valley Authority Paradise Preparation Plant. Test racks loaded with several different types of alloys have been installed at various points in the plant. Wear rates have been measured over a 2200 hour operating period. Results indicate that while stainless steels show very small materials losses, carbon steel and CorTen experience significant material wastage in the process areas tested. Ongoing studies are underway in both laboratory and plant environments.

Full textAbstract:
The construction industry is labour-intensive, and any conflict involving workers affects the project's overall performance. The present study identified potential conflicting factors and assessed the relative influence of those factors on the performance of workers. A total of nine conflicting factors were identified based on relevant literature. A questionnaire survey was prepared, and responses were collected from workers by visiting four construction sites in India. The data was then analysed using descriptive statistical methods. It was found that payment delay and overworking were the most influential conflicting factors on worker performance. Inadequate resources, lack of communication, lack of education/training, time pressure, and factors related to workplace environments such as noise and dust were also identified as contributing factors to worker conflicts. In contrast, lack of safety and low-risk perception were identified as the least impactful on performance. Addressing these conflicting factors can improve worker performance and job satisfaction, improving the project's overall performance. The study's findings can serve as a guide for employers and managers to create a positive work environment and address the difficulties faced by construction workers at job sites.

Lam, Terence, and Keith Gale. Construction frameworks in the public sector: Do they deliver what they promise? Property Research Trust, 2021. http://dx.doi.org/10.52915/sbuk7331.
Full textAbstract:
We demonstrate that the use of Performance Frameworks for the procurement of construction projects by public sector organizations in the UK (specifically, in England) leads to significantly improved outcomes in terms of time, cost, quality, sustainability and closer relationships, than the traditional ‘open tender’ approach of procuring discrete projects, individually. We identify the factors that lead to such improvements. We label these: supplier’s task performance factors (project staff, execution approach, competence of firm and structure of firm); supplier’s contextual performance factors (trust and collaboration, culture and conscious behaviour); and client’s organisational factors (incentives, performance monitoring, procurement approach and communication). And we offer a performance improvement model that will help project managers to select the most appropriate suppliers at the procurement phase, to achieve successful project outcomes. The model can also be used to drive project performance further, by adopting client’s organisational factors during the procurement and construction phases. By applying the research conclusions, suppliers will be able to focus on communicating their strengths in the relevant aspects of task and contextual performance for technical tender proposals, and so increase the value of their services and the probabilities of winning work. And the analysis can be used by policy makers to help in drafting regulations and legislation on formal frameworks, in ways that will improve the delivery of policy objectives.

Full textAbstract:
The need to conduct complex operations over time results in U.S. forces remaining in deployed locations for long periods. In such cases, more sustainable facilities are required to better accommodate and protect forward deployed forces. Current efforts to develop safer, more sustainable operating facilities for contingency bases involve construction activities that redesign the types and characteris-tics of the structures constructed, reduce the resources required to build, and reduce resources needed to operate and maintain the com-pleted facilities. The Automated Construction of Expeditionary Structures (ACES) project was undertaken to develop the capability to “print” custom-designed expeditionary structures on demand, in the field, using locally available materials with the minimum number of personnel. This work investigated large-scale automated “additive construction” (i.e., 3D printing with concrete) for construction applications. This document, which documents ACES energy and modeling, is one of four technical reports, each of which details a major area of the ACES research project, its research processes, and associated results, including: System Requirements, Construction, and Performance; Energy and Modeling; Materials and Testing; Architectural and Structural Analysis.

Full textAbstract:
Earthquake disasters in the United States account for $6.1 billion of economic losses each year, much of which is directly linked to infrastructure damage. These natural disasters are unpredictable and represent one of the most difficult design problems in regard to constructing resilient infrastructure. Structural floor and roof diaphragms act as the horizontal portion of the lateral force resisting system (LFRS), distributing the seismically derived inertial loads out from the heavy concrete slabs to the vertical LFRS. Composite concrete-filled steel deck floor and roof diaphragms are ubiquitously used in commercial construction worldwide due to the ease of construction and cost-effective use of structural material. This report presents a series of composite steel deck diaphragm Push-out tests at full scale that explore the effect that cyclic loading has on the strength of steel headed stud anchors. The effect that cyclic loading has on structural performance is explored across the variation of material and geometric parameters in the Push-out specimens, such as concrete density, steel headed stud anchor placement and grouping, steel deck orientation, and edge conditions. As compared to prior tests in the literature, the push-out tests conducted in this work have an extended specimen length that includes four rows of studs along the length rather than the typical two rows of studs, and an ability to impose cyclic loading. This provides novel insight into force flows in the specimens, failure mechanisms, and load distribution between studs and stud groups.

Structural floor and roof diaphragms act as the horizontal portion of the lateral force resisting system (LFRS), distributing the seismically derived inertial loads out from the heavy concrete slabs to the vertical LFRS. Concrete-filled steel deck diaphragms are ubiquitously used in steel construction worldwide due to the ease of construction and cost-effective use of material. This report first presents a series of concrete-filled steel deck push-out tests that explores the effect of cyclic loading on the strength of steel headed stud anchors. The effect that cyclic loading has on structural performance is explored across different concrete densities, steel headed stud anchor placements and groupings, steel deck orientations, and edge conditions. As compared to prior tests, the push-out tests conducted in this work included four rows of studs along the length rather than the typical two rows, and an ability to impose cyclic loading. This provided novel insight into force flows, failure mechanisms, and load distribution between studs and stud groups. Most of the specimens also used lightweight concrete, as is common in high seismic zones.Secondly, this report describes a full-scale experimental concrete-filled steel deck diaphragm specimen which explored the cyclic behavior and capacity of this structural system. This experiment builds on previously reported experimental studies. This specimen demonstrated force distribution and flows in an indeterminant floor system and captured realistic boundary conditions and construction practices that affect the performance of this system in building structures. The results showed that concrete-filled steel deck diaphragms fail as expected and may have significant overstrength. Furthermore, a finite element framework is presented that can simulate cyclic fracture through the use of a high-fidelity steel material model. This framework was used and validated against nine experimental push-out specimens tested and documented as part of this research. The simulation capacity provides an avenue to further investigate this structural system through simulated parametric study.

Full textAbstract:
During the lifecycle of a bridge, deterioration of the concrete deck originates from many sources, e.g., corrosion due to water infiltration in conjunction with chlorides from the use of de-icing salts. Such deterioration may be affected by any one of the following six actions relevant to a bridge from conception to demolition: design, construction, in-service conditions, maintenance, repair and rehabilitation, and replacement. Many researchers have studied the relationships between these sources and their consequences. However, the relationship between construction defects and inspection practices, and its impact on the deterioration process has not yet been identified. This project focuses on the development of predictive models to assess the impact that defects present during concrete bridge deck construction may have on the lifecycle performance of the bridge deck in terms of the chemical and environmental deterioration relevant to Indiana. Based on the relevant cost information from the Indiana Department of Transportation (INDOT), a methodology is developed here to determine the potential costs associated with this deterioration. Recommendations relevant to construction and inspection and data collection practices are discussed to improve future bridge construction and inspection practices. The models and methods developed in this work will enable INDOT to better predict the accelerated deterioration of a concrete deck when a construction defect has been identified and the associated additional cost.

Complex military operations often result in U.S. forces remaining at deployed locations for long periods. In such cases, more sustaina-ble facilities are required to better accommodate and protect forward-deployed forces. Current efforts to develop safer, more sustaina-ble operating facilities for contingency bases involve construction activities that require a redesign of the types and characteristics of the structures constructed, that reduce the resources required to build, and that decrease the resources needed to operate and maintain the completed facilities. The Automated Construction of Expeditionary Structures (ACES) project was undertaken to develop the capa-bility to “print” custom-designed expeditionary structures on demand, in the field, using locally available materials with the minimum number of personnel. This work investigated large-scale automated “additive construction” (i.e., 3D printing with concrete) for con-struction applications. This report, which documents ACES materials and testing, is one of four technical reports, each of which details a major area of the ACES research project, its research processes, and its associated results. There major areas include System Require-ments, Construction, and Performance; Energy and Modeling; Materials and Testing; Architectural and Structural Analysis.

Full textAbstract:
Cracks and their formations in concrete structures have been a common and long-lived problem, mainly due to the intrinsic brittleness of the concrete. Concrete structures, such as rigid pavement and bridge decks, are prone to deformations and deteriorations caused by shrinkage, temperature fluctuation, and traffic load, which can affect their service life. Rehabilitation of concrete structures is expensive and challenging—not only from maintenance viewpoints but also because they cannot be used for services during maintenance. It is critical to significantly improve the ductility of concrete to overcome such issues and to enable better infrastructure quality. To this end, the self-healing cementitious composites (SHCC) investigated in this work could be a promising solution to the aforementioned problems. In this project, the team has designed a series of cementitious composites to investigate their mechanical performances and self-healing abilities. Firstly, various types of fibers were investigated for improving ductility of the designed SHCC. To enhance the self-healing of SHCC, we proposed and examined that the combination of the internal curing method with SHCC mixture design can further improve self-healing performance. Three types of internal curing agents were used on the SHCC mixture design, and their self-healing efficiency was evaluated by multiple destructive and non-destructive tests. Results indicated a significant improvement in the self-healing capacity with the incorporation of internal curing agents such as zeolite and lightweight aggregate. To control the fiber distribution and workability of the SHCC, the mix design was further adjusted by controlling rheology using different types of viscosity modifiers. The team also explored the feasibility of the incorporation of colloidal nano-silica into the mix design of SHCC. Results suggest that optimum amounts of nano-silica have positive influence on self-healing efficiency and mechanical properties of the SHCC. Better hydration was also achieved by adding the nano-silica. The bonding strength of the SHCC with conventional concrete was also improved. At last, a standardized mixing procedure for the large scale SHCC was drafted and proposed.

A study was performed by the Energy Branch of the US Army Engineer Research and Development Center, Construction Engineering Research Laboratory, on behalf of the US Army Installation Management Command under the Installation Technology Transition Program. The focus of the study was related to maintainability and operability issues associated with High Performance Sustainable Buildings (HPSBs). This study was conducted primarily based on information gleaned from telephone and web conference discussions with installation Directorate of Public Works personnel including Operation and Maintenance (O&M) Chiefs, energy managers, maintenance supervisors, and maintenance technicians. Experiences with HPSBs varied from installation to installation. For example, some installations had very positive experiences with photovoltaic (PV) arrays while other sites questioned their practicality due to maintainability problems. One site noted that PV technologies are changing so rapidly that procuring spare/repair parts becomes difficult or impossible when vendors discontinue supporting their older technologies or manufacturers go out of business. Based on discussions with the installation O&M personnel, a table of pro and con recommendations for 25 technologies, which are commonly implemented on HPSBs, was prepared and is included in this report.
