Despite the availability of various cost control techniques and assessment of the effect on building project techniques many construction projects still do not achieve their cost and time objectives. Research in this area so far has maini been devoted to identifying causes of cost and time overruns. There is limited research geared at studying factors inhibiting the ability of practitioners to effectively control their projects. To fill this gap, a survey was conducted on 250 construction project organisations in the UK, which was followed by face-to-face interviews with experienced practitioners from 15 of these organizations. The common factors that inhibit both time and cost control during construction projects were firstly identified. Subsequently 90 mitigating measures have been developed for the top five leading inhibiting factors-design changes, risks/uncertainties, inaccurate evaluation of project time/duration, complexities and non-performance of subcontractors were recommended. These mitigating measures were classified as: preventive, predictive, corrective and organizational measures. They can be used as a checklist of good practice and help project managers to improve the effectiveness of control of their projects.

1.1 BACKGROUND OF THE STUDY
In construction almost all clients are interested in obtaining fully functional facilities completed in time, cost, quality and scope. A builder who so able to construct within the estimated time and budget, to the right standards and scope is an excellent builder.
Cost control is a process where the construction cost of the project is managed through the best methods and techniques so that the cotr s nc suffer losses when carrying out the activities of the project. One of the aim of cost control is to construct at the cheapest possible costs consistent with the project objectives. Ultimately the decision of the manager that something should be done differently and the translation of that decision into practice are the actions to achieve control (Harris and McCaffer 2002).
Raina (1999) observes that it is of little use after a process has been completed to discover that its cost was actually too much. Most project managers and contractors in Nigeria find difficulty in controlling costs on their constructions sites due to a number of problems which include poor project preparation, lapse in management and control, over budgeting, poor materials, labour shortages, increased cost of materials, delays in deliveries, wastage of materials, unexpected whether changes, loss of materials, insecurity and poor communication.
This results into cost and time overruns, conflicts, and sometimes abandoning projects. This study was therefore carried out to identify the cost control techniques used in Nigeria and propose effective ones to building construction parties.
It specially worked at problems faced by the contractors in controlling the cost on site, studied the cost control techniques commonly used by the contractors during the construction stage and proposed remedies to be used by contractors on sites control their costs.
