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

The quality of structures in Nigeria, particularly those built by indigenous construction businesses and specialists, cannot be compared to those in affluent countries or even other West African countries such as Benin Republic, Togo, and Ghana. Many factors have been blamed for this dreadful condition, including a scarcity of trained tradespeople, the lack of national quality standards and codes of practise, and inadequate government regularity policies, to name a few. This study was carried out in order to determine the level of compliance with existing quality management standards in public building projects in Nigeria’s South-Eastern States, using the NIOB/NBC quality checklist. A structure’s quality is influenced by the construction methods, project quality management strategy, and project health and safety plan. The effectiveness of the quality management approach depends on a checklist document that guides on workmanship, construction materials, inspection, material sampling, and testing. The checklist sheet includes 62 characteristics that were deemed significant. The 62 variables were divided into eight categories: subsurface, timber, formwork, concrete work, steel reinforcement, block work, rendering, and roofing. The data were analysed using the weighted average mean index (Iimp), which varied from -2 to 2. The subsurface sub-sector came in first with a mean score of 1.5752, followed by the roofing sub-sector. Blockwork comes in last with a mean score of 1.3297, followed by the rendering sub-sector with a mean score of 1.3492. The 900 structured surveys distributed received 730 responses, reflecting an 81.1 percent response rate. Building professional associations and all levels of government regulatory authorities should provide quality control checklists and approved mechanisms for construction project monitoring.
