Opis:
It has become almost impossible to have engineering and construction projects completed within the initial time and cost; this is a result of many factors the industry is being plagued with ranging from estimating time and cost. This paper presents strategic methodology that fosters effective engineering and construction projects management with respect to duration/time - cost. The project success is a two-faced phenomenon. On the one hand, project success can be approached from a triangular point of view of project objectives. Performance, cost, time, quality, and safety of a given particular project should be in accordance with the strategic objectives of work logics and methodology at the workflow organization. The main objective of this research is to develop methodology that will help company or individual construction practitioners achieve profitable objectives in the execution of construction projects. For this reason, use of multiple methods of work organization and their competitive model involving several considerations of a wide range of factors, (besides profit maximization and competition) that affect the margin-size decision; use of qualitative and subjective appropriate work organization, to more realistically capture the decision-making process were suggested. The defined optimum construction project works duration should be made in view of all major influential factors as pointed out in this paper (determinate and indeterminate) resulting into deviation of the estimated time and budget cost. At the consideration of the factors the most likely project duration time and it corresponding cost should be regulated (controlled) and some part of the estimates should be saved in form of insurance, and consequently profitable project would be achieved despite the influences of all factors affecting the project.

Opis:
The paper presents methods of determining the location of cost buffers and corresponding contingency costs in the CPM schedule based on its work breakdown structure. Application of correctly located cost buffers with appropriately established reserve costs is justified by the common overrunning of scheduled costs in construction projects. Interpolated cost buffers (CB) as separate tasks have been combined with relevant summary tasks by the starttostart (SS) relationship, whereas the time of their execution has been dynamically connected with the time of accomplishment of particular summary tasks using the “paste connection” option. Besides cost buffers linked with the group of tasks assigned to summary tasks, a definition of the cost buffer for the entire project (PCB) has been proposed, i.e. as one initial task of the entire project. Contingency costs corresponding to these buffers, depending on the data that the planner has at his disposal, can be determined using different methods, but always depend on the costs of all tasks protected by each buffer. The paper presents an exemplary schedule for a facility and the method of determining locations and cost for buffers CB and PCB, as well as their influence on the course of the curve illustrating the budgeted cost of work scheduled (BCWS). The proposed solution has been adjusted and presented with consideration of the possibilities created by the scheduling software MS Project, though its general assumptions may be implemented with application of other similar specialist tools.
