Conceptual cost estimates play a crucial role on initial project decisions although scope is not finalized and very limited design information is available during early project stages. At these stages, cost estimates are needed by the owner, contractor, designer or the lending organization for several purposes including; determination of feasibility of a project, financial evaluation of a number of alternative projects or establishment of an initial budget. Conceptual cost estimates are not expected to be precise, since project scope is not finalized and very limited design information is available during the pre-design stages of a project. However; a quick, inexpensive and reasonably accurate estimate is needed based on the available information. In this study, conceptual cost estimating models will be developed for urban railway systems using data of projects from Turkey. The accuracy of the models and advantages of the study will be discussed.

Conceptual cost estimation of building projects with regression analysis and neural networks Sönmez, Rifat (2004-08-01) Conceptual cost estimates play a crucial role in initial project decisions, although scope is not finalized and very limited design information is available during early project stages. In this paper, the advantages and disadvantages of the current conceptual cost estimation methods are discussed and the use of regression, neural network, and range estimation techniques for conceptual cost estimation of building projects are presented. Historical cost data of continuing care retirement community projects we...
A Support vector regression method for conceptual cost estimate of construction projects Yolasığmaz, İsmet Berki; Sönmez, Rifat; Department of Civil Engineering (2015) Conceptual cost estimate is very important for initial project decisions when the design information is limited and the scope is not finalized at the early stages of the construction projects. It has serious effects on planning, design, cost management and budgeting. Therefore, the decision makers should be as accurate as possible while estimating the conceptual cost at the initial stage since a misestimation on the conceptual cost may lead to serious problems during feasibility analysis or at the later sta...

Comparison of parametric models for conceptual duration estimation of building projects Helvacı, Aziz; Sönmez, Rifat; Department of Civil Engineering (2008) Estimation of construction durations is a very crucial part of project planning, as several key decisions are based on the estimated durations. In general, construction durations are estimated by using planning and scheduling techniques such as Gannt or bar chart, the Critical Path Method (CPM), and the Program Evaluation and Review Technique (PERT). However, these techniques usually require detailed design information for estimation of activity durations and determination of the sequencing of the activitie...
A Method to decrease common problems in effort data collection in the software industry Özkaya Eren, Ayşegül; Demirörs, Onur; Department of Information Systems (2012) Efficient project planning and project management is crucial to complete the software projects in expected time and requirements. The most critical stage in project planning is estimation of the software size, time and budget. In this stage, effort data is used for benchmarking data sets, effort estimation, project monitoring and controlling. However, there are some problems related to effort data collection in the software industry. In this thesis, a pilot study and survey study are conducted to observe co...
