Abstract :

The construction industry is complex in nature, as it contains a number of project team members like the client, consultants, contractors, stakeholders, shareholders, and regulators who are responsible in overseeing the performance and time schedule of any building project. The study objective on factors affecting performance and time schedule for Multi–Unit Residential Buildings, (MURBs) construction projects in Dar–Es–Salaam, Tanzania, was to explore factors affecting performance and time schedule for MURBs construction in Dar–Es–Salaam, Tanzania. To documents and analyze factors that drives positively and negatively, the performance and time schedules for MURBs construction projects respectively, as well as to comment on mitigation measures that can improve performance and time schedule of MURBs construction projects. This study was designed to obtain views from MURBs project stakeholders, regarding their perception on factors that affects MURBs projects. Purposive sampling was adopted using a sample of 50 MURBs stakeholders from NSSF, NHC TBA, PPF, WHC, etc. Data were collected through structured questionnaire and literature review, and analyzed using Microsoft Excel while using tables presentation. 50 questionnaires were distributed to Quantity Surveyor, Architects, and Engineers in which 46 were returned. The finding reveals that 12 factors affect performance and time schedule for MURBs construction projects in Dar–Es–Salaam, Tanzania positively and negatively, in terms of cost, time and quality. The result showed that late payment, under estimation, inadequate planning and communication, lack of competent project manager, scope change, design change, conformance to the specification were the most factors affecting MURBs performance. Furthermore, it was found that late completion and late payments influence cost overrun, which eventually raise disputes and claims and sometimes arbitration. Moreover, some mitigation measures like ensuring proper planning of work, clear information and communication channels, clear information and hiring skilled labor and committed leadership and management were found to be of great help in addressing MURBs construction performance if well implemented. The study recommends the management structure of MURBs construction project to resemble the one in Australia, hence helping the Tanzanian construction industry, specifically the MURBs stakeholders
