Abstract

The majority of construction industries in developing nations are challenged with a high cost of construction in the delivery of housing, nevertheless, the incompetence of construction operators in the management of client briefing toward achieving cost-efficient design practices is an additional problem. Thus, the low-income earners perceive affordable housing a phantasm, thereafter, living in the slums and squatters were social crimes are invented. This practice continues increases on daily bases without restrained. Based on this assertion, demand the most important reason to investigate construction cost increase a source for unaffordable housing delivery in the cities. The objectives of this study are to establish the techniques that will restraint construction cost within budgeted cost in order to deliver inexpensive housing for poor residents in the cities. The methodology used to achieve the aim and objective of this study is a sequential mixed method that involved quantitative and qualitative techniques, questionnaires were administered to the architects, contractors, project managers, quantity surveyors, site engineers, and contract managers. Questions related to their knowledge of construction cost increase a source for unaffordable housing delivery in the cities. Data collected were analysed using SPSS software that contains a descriptive statistical and principal component analysis (PCA) and the results obtained were validated using a qualitative process. The most influential techniques that will restraint construction cost within the initial budgeted cost are; establishment of contract management procedures initiated on site; adequate coordination of client briefing phase and transition to design phase through to construction stage; adequate establishment of client objectives through to implementation will reduce frequent alteration of drawings; constant promoting high standard design and implementation among professionals; adequate planning for the management of construction resources usage; and satisfactory planning for resources waste reduction during production. The deliberation of these identified techniques with client briefing on the aim and objectives of the proposed project will reduce frequent alteration of drawings and enhance the adequate planning for high standard design and implementation among professionals. Consequently, the established factors of techniques for construction operators will make housing constantly available at a cost within the reach of lower income earners.
