Subsequent to preparation of a valid base estimate for a construction project tender, it is required to add a bid markup on top of the base estimate. While an exaggerated bid markup weakens the competitiveness of the contractor, an underestimated one makes the contractor susceptible to financial losses. Therefore, an effective and reliable bid markup estimation method is indispensable to the success of a contractor both at the tender and the performance stages. The prevalent practice among contractors is to identify a certain percentage to add on the base estimate relying on their judgment without substantial ex! plicit support. In this thesis, a case based decision support system, which will count on the experience of the top experts of Turkish international contractors, will be constructed. Meanwhile, factors which are essential to bid markup estimation are to be identified.

Benefit-cost analysis for retrofitting of selected residental buildings in İstanbul Erdurmuş, Salih Buğra; Erant, Engin; Department of Civil Engineering (2005) During the evaluation of the seismic retrofitting option for risk reduction/mitigation measures to be applied over buildings, Benefit Cost Analysis is an often-used method. During this study of Benefit Cost Analysis, the condition that the earthquake can happen just after or sometime after retrofitting will be taken into consideration rather than some approaches that focus on the benefits and costs regarding the annual probability of the occurrence for possible earthquakes. The analysis will use conditional...
Determination of contingency for international construction project during bidding stage Ergin, Abdullah Arif; Sönmez, Rifat; Department of Civil Engineering (2005) Determination of contingency for international projects plays an important role for inclusion of risks taken by the contractor on the bid amount. Although determination of contingency is an important stage of bid preparation for international projects, the methods that are being used by Turkish contractors for quantification of contingency are very limited. In this thesis the factors affecting the contingency decisions of Turkish contractors for international projects will be investigated. The significance ...
Improving sub-contractor selection process in construction projects: Web-based sub-contractor evaluation system (WEBSES) Arslan, Gokhan; Kivrak, Serkan; Birgönül, Mustafa Talat; Dikmen Toker, İrem (Elsevier BV, 2008-05-01) One of the most important phases in the construction industry (CI) is the bidding process. During the bidding process, selecting the most appropriate sub-contractors (SCs) for the relevant sub-works is highly critical for the overall project performance. In order to select the most appropriate SCs for the project and prepare the most realistic and accurate bid proposal, general contractors (GCs) have to know all financial, technical and general information about these SCs. Within this context, GCs should co...
Building cost index forecasting with time series analysis Kibar, Mustafa Alptekin; Sönmez, Rifat; Department of Civil Engineering (2007) Building cost indices are widely used in construction industry to measure the rate of change of building costs as a combination of labor and material costs. Cost index forecast is crucial for the two main parties of construction industry, contactor, and the client. Forecast information is used to increase the accuracy of estimate for the project cost to evaluate the bid price. The aim of this study is to develop time series models to forecast building cost indices in Turkey and United States. The models dev...
Schedule delay analysis in construction projects: a case study using time impact analysis method Dayı, Songül; Elias Özkan, Soofia Tahira; Department of Architecture (2010) Inadequate or weak preparatory work before starting construction of any structure may cause serious problems during the construction period. For example, projects without sufficient detailed drawings or construction schedules and a disorganized building site can create many problems in the management and completion of the construction works. Consequently, the cost of construction increases digressively, the construction duration of the project extends and the quality of construction is affected adversely. T...
