Failing to adequately select the winning contractor can lead to problems in the project delivery phase such as bad quality and project delay; which ultimately results in cost overruns. There are two strategies involved with selecting contractors: one is the lowest tender, the other is called best value. Selecting the lowest tender is straightforward; the latter strategy would involve scoring the contractors' tenders on price and quality and ranking them. The aim of this research is to provide a model of determining the probability distributions of cost and time arising from choosing different

Construction projects in developing countries may suffer from time overruns, which are associated with cost overruns. This research project investigated both time and cost overruns on high-rise building projects in Dhaka, Bangladesh. Surprisingly, preliminary data analysis showed negligible cost overruns in comparison to time overruns. So, further analysis o f cost overruns was not considered in this thesis. This research project also investigated how the causes o f time-overruns can be mitigated. 72 time-overrun and 22 cost-overrun variables were identified through a literature review. These

The main concern of a construction client is to procure a facility that is able to meet its functional requirements, of the required quality, and delivered within an acceptable budget and timeframe. The cost aspect of these key performance indicators usually ranks highest. In spite of the importance of cost estimation, it is undeniably neither simple nor straightforward because of the lack of information in the early stages of the project. Construction projects therefore have routinely overrun their estimates. Cost overrun has been attributed to a number of sources including technical error in

While wastage of materials has become a serious problem requiring urgent attention in the Nigerian Construction Industry, cost overrun is a problem, which affects 90 percent of the completed projects in the world; the argument on how to reduce/eliminate cost overrun has been on-going for the past 70 years; as the on-site wastage of materials leads to increases in the final project cost. Studies from different parts of the world have shown that construction-material waste represents a relatively large percentage of the production costs.

Cost overruns in power plant projects frequently occur, and this very alarming phenomenon requires proper risk assessment and management in the early phase of power plant project development.

Further, a novel fuzzy canonical model (FCM) was developed and the complex causal risk-networks were modelled to understand the root causes of cost overruns.

The construction of infrastructure projects is characterised by cost overruns and time delays. Scholars view that the estimation approach and inappropriate tools and techniques used to forecast possible uncertainty in the construction processes are a primary cause of cost overruns and time delays on construction projects. Uncertainties encountered in the construction process are underestimated and these impact on the final cost and time of construction projects through a combination of individual construction activities. The study, therefore, examines the initial and final cost of construction

The negative impacts associated with highway pavement rehabilitation projects drove state highway agencies (SHAs) towards increased adoption of alternative contracting methods (ACMs) to accelerate the construction of such projects; hence, reducing these impacts on the travelling public. However, the application of such methods showed mixed results due to the lack of specific guidelines addressing the adoption of such methods and the selection of the best ACM for each project. This lack of guidelines stems from the lack of research studies examining the impact of each of these methods on the ti

This bachelor’s thesis is written in collaboration with Skanska. The purpose of this thesis is to implement a time and cost analysis to compare the standard working week with five variations of work arrangements to investigate which is the most profitable. The thesis also examines which factors affects profitability and whether shift work is a good alternative in the construction industry. Depending on choice of working arrangement, it is possible to reduce both time and cost for a project.A calculation model has been created to be able to compare the different working arrangements.

The present work deals with the study and analysis of the simultaneous optimization of time, cost and quality by using artificial intelligence technique; The approach is based on the use of genetic algorithms implemented in Matlab applied to a case study, the construction of a new University Campus in Cesena, focusing on the external walls of the building itself. The objective is to find a set of optimal solutions, equally valid, for the realization of stratigraphies of the different types of external masonry; It will then be the task of the designer to choose among possible solutions which he

Byggbranschen står idag för cirka 21 procent av Sveriges totala årliga utsläpp av växthusgaser. En stor utmaning är att kunna uppnå klimatlagens mål som innebär att Sverige inte ska ha några nettoutsläpp av växthusgaser i atmosfären de kommande decennierna. Samtidigt ökar behovet av fler bostäder i samband med en ökad befolkning. Betong är det material som dominerar dagens industriella byggande av flervåningshus och i samband med den tidigare svenska lagen som förbjöd träkonstruktioner med fler än två våningar är träbyggandet i Sverige inte lika etablerat i samma utsträckning som betongkonstru

Världen över sker ständiga budgetöverskridanden. Offentliga verksamheter har inte varit något undantag för dessa kostnadsöverskridanden, vilket skapar incitament till att förstå varför de uppstår. I de offentliga projekten drabbas fler än bara de projektansvariga vid budgetöverskridelser. Det är samhället i stort som får betala för arbetet eftersom det är skattefinansierade projekt. Examensarbetet utgör en fallstudie som genomfördes med syftet att skapa förståelse för varför budgetöverskridanden sker i en liten kommun. För att uppnå syftet har både sekundär- och primärdata använts i form av en

This work focuses on the need for new knowledge to allow hierarchical multi-project management to be conducted in the construction industry, which is characterised by high uncertainty, fragmentation, complex decisions, dynamic changes and long-distance communication. A dynamic integrated project management approach is required at strategic, tactical and operational levels in order to achieve adaptability. The work sees the multi-project planning and control problem in the context of supply chain management at main contractor companies. A portfolio manager must select and prioritise the project

Prefabricering av väggelement är en byggmetod under stark framväxt i byggandet av småhus de senaste decennierna. Kostnadseffektiviteten nämns ofta som ett skäl till att prefabricering av småhus har en sådan stor framväxt. Samtidigt har miljö- och klimatfrågan växt och då byggsektorn står för en stor del av Sveriges koldioxidutsläpp krävs det att byggsektorn ställer om till ett allt med hållbart byggande. Detta examensarbete har undersökt denna kostnadseffektivitet och hur och om en går att kombinera med ett hållbart byggande och sedan jämfört detta med platsbyggda väggar i trä. Underlag har ta
