Evaluating the Assessment of Indices of Building Project Quality Control Checklist in the South-Eastern States of Nigeria

Abstract

The quality of buildings, especially those executed by indigenous construction firms and professionals in Nigeria cannot be measurable with those of developed countries, or even those of other countries in the West African sub-region such as Benin Republic, Togo and Ghana. This ugly situation has been attributed to many factors, ranging from the dearth of skilled tradesmen, non-existence of national quality standards and code of practice and ineffective government regularity policies to mention a few. It is against this background that this study was undertaken to ascertain the level of compliance with existing quality management standards in public building projects in the South-Eastern States of Nigeria in accordance with NIOB/NBC quality checklist. The construction methodology, project quality management plan, and project health and safety plan are all factors that influence the quality of a structure. A checklist document that guides on workmanship, construction materials, inspection, material sampling, and testing is crucial to the success of the quality management strategy. The checklist document contains 62 variables that were regarded important factors.Subsurface, timber, formwork, concrete work, steel reinforcement, block work, rendering, and roofing were the eight sub-headings for the 62 variables. The evaluation was done on a 5-point Likert scale, and the results were analysed using the weighted average mean index (Iimp), which ranged from -2 to 2. With a mean score of 1.5752, the subsurface sub-sector came in first, followed by the roofing sub-sector.With a mean score of 1.3297, blockwork comes in last, followed by the rendering sub-sector with a mean score of 1.3492. 730 people answered to the 900 structured questionnaires that were distributed, representing an 81.1 percent response rate. Quality control checklists and approved systems for construction project monitoring should be provided by building professional groups and all levels of government regulatory agencies.
