Abstract:

In the construction industry, formwork plays a critical role in the construction of cast in situ reinforced concrete structures. Due to the rapid growth of the Indian economy, population growth, urbanization, and industrialization, the demand for housing and other built structures is increasing. To meet these requirements, quick construction is needed with less project completion time. The conventional system of formwork comprises nearly 50% of the total project completion time. Wastage and labour requirement is also high in conventional formwork systems. So, the use of modern formwork systems like aluminium formwork, tunnel formwork, etc., is increasing in the Indian construction industry. This paper aims to discuss and evaluate the various formwork systems available, and to show their impact on project duration, cost, quality, cycle-time, number of repetitions, labour requirements. Through literature review, data about various formwork systems available all over the world are collected. The current practices in India are known from various stakeholders through a questionnaire survey. Data analysis will be done using the data collected from the literature review and the questionnaire survey. The research will highlight the benefits and comparison of various types of formworks in terms of project duration, cost, quality, cycle-time, number of repetitions, labour requirements. This study concluded that implementing the modern formwork systems will improve the quality, safety, efficiency and minimise the cost and waste in construction. Keywords: Conventional formwork; Modern formwork systems; fast-track construction; Comparison; Indian construction sector.

Abstract:

AbstractFormwork systems are necessarily used in the implementation of the RC (reinforced concrete) structures. Formworks are required regardless of whether a construction is monolithic or prefabricated and used to form the engineering and general structures or structural elements, such as abutments, supports and decks of the bridges, tanks and retaining walls, but also industrial and accommodation facilities etc. Ensuring the OHS (occupational health and safety) during transport, assembly and disassembly of formworks is a necessary condition for the execution of RC works in a safe and economical way. The paper presents the analysis of the safety requirements for formworks. Furthermore, the general requirements for the execution of the formwork structures were discussed. The most common organizational and technological mistakes and cased of neglects related to the operation of the formwork which lead to infringement of the OHS regulations were also identified.

Abstract:

Formwork material and payroll are among the greatest costs in building reinforced concrete structures. Therefore, formwork engineering is a key factor affecting project success. Traditional formwork construction entails non-value-adding activities resulting in waste. The objective of this study is to adapt lean manufacturing techniques to formwork engineering in a bid to reduce waste, specifically by developing a lean formwork construction model. In the model, andon is used to establish an on-site quality control culture, allowing form workers to obtain assistance immediately whenever a problem occurs. In addition, formwork operations are pulled through the kanban system to reduce mould inventory and achieve continuous construction flow. A case study is used to validate the applicability of the proposed model. Results show that the proposed model can effectively reduce waste in the formwork construction flow and increase the value of operations, thus providing a new approach to improving formwork engineering.

Abstract:

Growing construction activities requires increase in construction materials. The conventional method of constructions results in a rise in construction waste. Formwork as a main factor to generate construction waste has been the topic of investigation. The permanent formwork has been introduced with the aim to: promote the construction technology process that put quality, safety and environment issues into account, reduce the cost of workers and reduce the overall time of construction project. At present the permanent formwork available in the market are made from steel, and plastic and the cost is still high. Therefore this study is looking at the potential of commercial wood-wool cement board (WWCB) as permanent formwork. A series of concrete columns were constructed with and without integrated WWCB with different configurations of WWCB as permanent formwork. These columns were subjected to axial load and the compressive strength and failure modes were recorded. The results show that the present of permanent formwork from WWCB improves the compressive strength of the column. With the permanent formwork, the size of concrete column can be reduced and able to support the same load as column without permanent formwork. Therefore this construction method can reduce the overall cost of construction.

Abstract:

Concrete is vastly used in construction due to its high compressive strength, and its ease of shaping. Formworks are used to render the desired shape to the material during its change from a liquid to a solid state, until the concrete develops the required strength. Removing the formwork early can cause excessive deformations or even failure; however, postponing removal also has a delaying effect in construction with economic consequences. In practice, the removal of the formworks is based on the development of the compressive strength vs. the self-weight and temporary loads related to the construction. This study aims to monitor the hardening of concrete columns by means of the reflection of ultrasonic waves. As concrete hardens, its mechanical impedance increases influencing the reflection that can be received by one-sided non-invasive measurements. By suitably selecting the stiffness of the ultrasonic buffer material, the moment that the concrete obtains a specific stiffness can be safely determined for the first time. Results demonstrate sensitivity of the technique on real scale formworks, as it can pinpoint the moment in which the formwork can be removed, while numerical simulations help in the understanding of the complicated wave field and validate the methodology.

Abstract: Formwork in construction is the use of support structures and moulds to create structures out of concrete which is poured into the moulds. Formwork can be made using moulds. Out of steel, wood, aluminium and , or prefabricated forms. 2. Formwork refers to either temporary or permanent moulds into which concrete or similar materials are poured. In the context of concrete construction, the falsework supports the shuttering moulds. 3. Formwork is an ancillary construction, used as a mould for a structure. Into this mould, fresh concrete is placed only to harden subsequently. The construction of formwork takes time and involves expenditure up to 20 to 25% of the cost of the structure or even more. The operation of removing the formwork is known as stripping. Stripped formwork can be reused. Reusable forms are known as panel forms and non-usable are called stationary forms. Keywords: Modified Formwork, Slab

Abstract:

The concrete used in floor slabs accounts for large greenhouse gas emissions in building construction. Solid slabs, often used today, consume much more concrete than ribbed slabs built by pioneer structural engineers like Hennebique, Arcangeli and Nervi. The first part of this paper analyses the evolution of slab systems over the last century and their carbon footprint, highlighting that ribbed slabs have been abandoned mainly for the sake of construction time and cost efficiency. However, highly material-efficient two-way ribbed slabs are essential to reduce the environmental impact of construction. Hence, the second part of this paper discusses how digital fabrication can help to tackle this challenge and presents four concrete floor systems built with digitally fabricated formwork. The digital fabrication technologies employed to produce these slab systems are digital cutting, binder-jetting, polymer extrusion and 3D concrete printing. The presented applications showcase a reduction in concrete use of approximately 50% compared to solid slabs. However, the digitally fabricated complex formworks produced were wasteful and/or labour-intensive. Further developments are required to make the digital processes sustainable and competitive by streamlining the production, using low carbon concrete mixes as well as reusing and recycling the formwork or structurally activating stay-in-place formwork.

Abstract:

The pursuit for complex geometries in contemporary architecture is driving innovation towards an unconstrained fabrication freedom for building components. Concrete is a building material with excellent structural and architectural qualities, which has the theoretical capacity of being cast into any shape. However, in practice, concrete is generally limited by the formwork manufacturing industry to simple, planar shapes. To overcome this fabrication limitation, this research investigates the use of large-scale 3D-printed plastic formworks for concrete components. This novel construction method takes advantage of the load-bearing capacity of concrete and relies on the fabrication-freedom inherited from the 3D printed formwork, thus making complex topologies and precise details possible for concrete structures. To demonstrate the potential applications of this method, skelETHon —a functional four-meter-long concrete canoe— was designed, built and raced in a regatta on the Rhine river. The research focused on the optimization of the 3D printing process for large-scale plastic formworks and on improving the stability of the thin formwork shells during casting.

Abstract:

Formwork engineering plays a crucial role in cost, efficiency, quality, and schedule in civil engineering. Currently, wood-plastic formwork, which has favorable mechanical properties such as wood and excellent stability, formability, ease of demolding, and time-saving as plastic, is earning its increasing reputation in construction. This work focuses on mechanical properties of two types of new composite wood-plastic formworks with aluminum alloy frame used for construction, that is, single-span simply supported and three-span continuous formworks. Experimental investigation shows that the two types of wood-plastic formworks demonstrate favorable performance, and the deflections and stresses are within the allowable range, thereby satisfying the structural bearing requirements. Numerical analyses confirm that the results of the refined and general finite element models are consistent with the experimental results, but the former has a higher accuracy. When the requirement of accuracy is not too strict, the general model is preferred, given the modeling convenience and high efficiency. On the basis of experimental and numerical investigations, practical simplified formulas are proposed to facilitate rapid calculation and evaluation considering transverse deflection and inconsistency of two materials. Therefore, the results in this work can provide a theoretical basis for developing and applying the new formworks.

Abstract:

The construction industry recorded high rates of fatalities and injuries due to falls at the workplace. Among other activities, concrete formwork tends to have more fatal falls. This study aims to understand the fall-related safety issues in the formwork lifecycle of construction projects. To achieve this, the process of formwork activities was mapped, and the safety risks associated with each activity were classified. Method development and risk identification focused on interviews with construction professionals involved in the construction of formwork and site observations of the formwork activities. The overall finding was that pouring, stripping, and erection activities have more issues related to falls. Future research is being carried out to assess the risks of falls from the construction experts’ views to prevent fall accidents in the future.

Quantitative calculation of the mechanical state of climbing formwork equipment is an important technical means of ensuring safety during super-high building construction. This work thus introduces a hydraulic climbing formwork equipment structure and subsequently analyzes the construction process and the main working state of the hydraulic climbing formwork equipment. Then, for the design of the outer climbing frame of the hydraulic climbing formwork, an approximate analytical method for solving the node reaction force is proposed. Finally, combined with the actual engineering, the calculation results of the approximate analytical method and the finite element method are compared, and the calculation and analysis methods of the hydraulic climbing formwork equipment frame and key nodes are introduced. The calculation analysis process and related conclusions can be used as engineering reference for similar projects.

Abstract:

Recent increases in the number of irregularly shaped tall buildings have created a need for more applicable formwork methods and automated support for formwork layout planning, which has mainly depended on heuristic approaches based on the intuitive judgment of experienced engineers. This study proposes a new table formwork method integrated with a systematic layout planning approach for tall building construction. Adjustable subunits of the formwork cope with diverse building shapes and the software-based mathematical model helps practitioners make useful layouts for the method with minimal time and effort. In a case study, the proposed layout planning model offered lower costs and improved work efficiency in less time than the heuristic approach. Supported by the planning model, our advanced formwork method showed a 15.5% increase in covered area of irregularly shaped building floors and a 23.9% decrease in material costs compared with existing table formwork methods.

Abstract:

This article reports a quantitative investigation of the surface characteristics of normal concrete manufactured with different types of formworks and bonding strength between pine resin-based adhesives and concrete surfaces. Three types of formworks and adhesives with different ratios of pine resin to wax were prepared. Scanning electron microscopy, energy-dispersiveX-ray spectroscopy, white-light scanning interferometry, and electrophoretic light scattering were utilized for the surface characterization of concrete, and a bonding test was performed. Test results showed that the surface roughness of concrete was significantly influenced by the type of formwork; all techniques including visual observation provided similar results. On the contrary, chemical compositions and electrical characteristics were not influenced by the type of formwork. Bonding test results showed that bonding strength increased as the ratio of wax increased and the degree of the concrete surface roughness increased. The results of this study indicate the feasibility of pine resin-based adhesives for concrete structures as green construction materials.

Abstract:

Erection of high quality buildings and structures within a reasonable time frame is the crucial factor for the competitiveness of any construction organization. The main material used in high-rise construction is insitu reinforced concrete. The technology of its use is directly related to the use of formwork systems. Formwork systems and formwork technologies basically determine the speed of construction and labor intensity of concreting operations. Therefore, it is also possible to achieve the goal of reducing the construction time and labor intensity of works performed by improving the technology of formwork systems use. Currently there are unresolved issues in the area of implementation of monolithic technology projects, and problems related to the selection of a formwork technology, high labor intensity of works, poor quality of materials and structures, etc. are the main ones. The article presents organizational and technological measures, by means of which introduction it is possible to shorten the duration of construction. A comparison of operations performed during formwork installation according to the conventional technology and taking into account the implemented organizational and technological measures is presented. The results of a comparative analysis of economic efficiency assessments are also presented on the example of a specific construction project before and after the implementation of the above mentioned measures. The study showed that introduction of the proposed organizational and technological model taking into account optimization of reinforcing and concreting works significantly improves the efficiency of a high-rise construction project. And further improvement of technologies for the use of insitu reinforced concrete is a promising direction in the construction of high-rise buildings.

Abstract:

The civil and construction industry is the basis of industries, it has always been known as the "leading industry" and in such industry the basic material is reinforced concrete. Even in this 21st century materials science and engineering methods have developed perfectly, reinforced concrete still is the main structure material in civil and construction industry. Formwork activity is one of indispensable matters during concrete forming and hardening processes. Once the forming process has defect, it might cause the formwork collapse during the concrete placing procedure. Such damage will result in pecuniary loss or workers life. This illustrating that the formwork is one of the most important materials in theconstruction industry. In general, formwork is mainly usedtimberas its rawmaterial. Therefore, the wooden formworkwill naturallydestruct and discard after repeating four to six times. But the remaining nail and chemicals treatment on the timber surface of the waste formwork always make the subsequent activity not easily. Such process does not echo todays trend of emphasis on the energy conservation and environmental protection. Besides, in order to keep the progress of the industry, all kinds of civil and construction industries are still continuous without considering the global temperature is getting warmer. But the timber,asaformwork rawmaterial,thespeedof deforestation is far behind the progress of forestation. Timber material will bedeforested somedaywith such vicious cycle. Therefore, if there is any appropriate material to replace wooden formwork, it will be a valuable issue for further research. The subject of this research is using value analysis to compare function and cost between plastic formwork plate and wooden formwork plate. For the study analysis, due to thelife cycleoftheplastic formwork plate andwooden formwork plate are notthe same, so this research developstheconceptoflife cost for doing the performance comparison between plastic formwork and wooden formwork with workability, cost, flat surface and environment.

Abstract:

The relevance of this article is related to the problem of standardization of technological processes in which there is construction equipment for concrete work. Almost all construction processes are performed using construction equipment. The arrangement of monolithic structures is accompanied by the processes of installation and dismantling of the formwork. It is impossible to make a reasonable choice of options for equipping construction processes according to the existing standard time norms. For all possible variants of column formwork, almost the same time norms are used [1]. The article considers the comparison of several formwork options for the installation of monolithic reinforced concrete columns of frame structures. To determine the duration and complexity of the process used the method of integer rationing [2], which allows taking into account even minor changes in the formwork. Calculation by this method makes it possible to select the most effective options for formwork. As a basis, this technique uses an analysis of the number of actions and responsibilities of these actions in relation to the quality of the process and its reliability. Any construction equipment is characterized by structural and technological versatility, which also affects the choice of options conditions of the process, so the article provides an analysis of these factors in terms of quality. If in the structure of the structure there are columns with different cross-sectional dimensions or heights, the preference is given to formwork options with greater structural versatility. The material of the article opens a whole direction for further research in the field of construction equipment in other processes.

Abstract:

The Upper Longitudinal Beam casting on the Jabodebek LRT Project requires a shoring to be able to withstand the workloads. To avoid the failure of formwork construction, formwork must meet the strength, stiffness, and stability requirements for each formwork component material. The analysis is carried out on the value of bending stress, deflection, and shear that occur in each component of formwork. From the analysis carried out each obtained as follows. Strength requirements with flexural stress values that occur in Plywood, Girder GT 24, and Steel Waller SRZ materials, each of which is smaller than σ permit = 100 kg / cm2, 70000 kg / cm2, and 1200 kg / cm2. Stiffness requirements with deflection values that occur on Plywood and Girder GT 24 material are Δ permit = l / 400. Whereas the SRZ Steel Waller fulfills Δ permit = l / 240. Stability requirements with shear stress values that occur in Plywood, Girder GT 24, and Steel Waller SRZ materials, each of which is smaller than τ permit = 12 kg / cm2, 1400 kg / cm2, and 696 kg / cm2. Peri Up Shoring can support all formwork loads. So it can be said that the construction of the Upper Longitudinal Beam formwork is in a safe condition.

Abstract:

The goal of this paper is to yield insights into the forming, reinforcing, and pouring of concrete buildings, focusing on design, functionality, failure, and safety aspects. The concrete construction process has different moving parts along the form–pour–strip cycle, and the authors aimed to analyze the information pertaining to formwork and rebar design, reasons for failures of formwork and hardening concrete, various hazards on jobsites, and safe work practices. The intent of this study was to seek and analyze the experiences of industry professionals on the above-stated aspects. In total, five well-experienced industry professionals working in concrete forming, reinforcing, and pouring were interviewed. Through comparative analysis of the interview results, the authors were able to gather valuable data related to designs of formwork system and rebars, field practices, jobsite hazards, and safety requirements. Interview results revealed that functionality and applied loads are the determining factors in any design considerations when it comes to formwork system and rebars for concrete buildings. Another finding was that a construction project does not wait for a concrete element to reach its full compressive strength at 28 days before proceeding with the work since the element can hold most construction loads after 3 or 4 days. In addition, the failures which occur in concrete buildings are a result of formwork breakdown, defective formwork layout, and concrete damage due to corroded rebars and inadequate curing procedure. Lastly, interview results revealed that the single leading hazard during concrete works is working at heights which can be minimized using fall arrest systems or engineered guardrails for improved safety.
