One of the responses to the critical failings of separation of design and construction processes of traditional procurement system is the development of management contracting (MC) procurement system. Several studies have indicated MC procurement system to be most suitable for large and complex projects, when on-time project delivery is required, and when flexibility during construction is desired. Owing to the involvement of the Management contractor at both design and construction stage of projects, the management contractors play more significant role in the benefits that MC system has show

Determining the most appropriate contractor for a construction project is a highly critical issue.

Abstract:
In the bidding procedure not only the contractor but also the construction owner make a number of vital decisions, the consequences of which are significant. The contractor has to decide whether to take part in a given bid and, having been accepted, he/she has to prepare a bidding offer. Its essential element is the mark-up introduced to the calculation of the bidding price. On the other hand, the investing construction owner has to decide which contractors are the closest to his/her requirements. The article presents mathematical models concerning the decisions made by the contractor and cons

Abstract:
The cost and determination of construction projects are key issues for both customer and contractor when entering into a construction contract. For customers, calculation and evaluation of the cost of construction projects is complicated by the problem of underpricing, which may lead to the failure of contractors submitting a bid for a project, and, in addition, overpricing may lead to an overestimation of the average market value of specific groups of works. Therefore, the aim of the study is to compare the quality assurance of different contractors’ contracts using a multi-functional decisio

A large number of stakeholders in construction projects makes the construction industry prone to disputes. The historical separation between design and construction add to this phenomenon by having a consultant for design and a contractor for construction. Communication breakdown, frequently, is the first sign of problems, notably in the relationship between the Contractor and the Consultant. Therefore, it appears that the split between design and construction has given rise to two separate cultures in the construction industry.
