ABSTRACT
Planning in construction involve defining the activities, actions, time, cost, durations and performance milestone which will result into successful completion of the project. Previous researches attributed insufficient construction planning to Nigerian indigenous construction companies, this insufficiency in construction planning was found to contribute to their low productivity, profitability, time overrun and cost overrun. This study was carried out to assess construction project planning of indigenous contractors with a view to enhance their performance. The objectives of the research were to assess contractors’ perception of construction project planning, articulation of contractors’ current method of construction project planning and assessing the efficiency of each contractor’s method of planning construction projects. The methodology of the research involve use of purposive sampling technique, sample size of 50 companies was determined using 90% confidence level from a population size of 1920 calculated with sample size table and formula. Questionnaire was self-administered to respondents, questionnaire (A) was administered to project managers of the organizations which contains questions that aim at assessing how organizations plan and what planning entails in their organizations, this questionnaire record 83% response rate. Questionnaire (B) was administered to professionals in the organizations who manage construction on site, questionnaire (B) aim at assessing the effectiveness of construction planning, problems associated with construction planning and how to improve construction planning, questionnaire (B) records 88% response rate. Questionnaires were analyzed and results was presented in tables and bar charts. Findings from the research revealed that construction project planning is insufficient and requires improvement. Cost overrun, time overrun, poor scope control and reduction in profit are problems experienced by
vi
contractors. The failure of construction project planning was attributed to client unethical dealings, lack of integrity in financial dealings of client and poor communication among project members. In order to improve planning of construction project, the research recommends contractors to perform financial and ethical check on client, employ distinct project manager to each project, employ the use of computerised systems and experience in planning construction projects. The research also recommend contractors to improve communication among project team through establishment of reliable and accessible communication channel.
