Adequacy of defects liability periods for public construction projects in Ghana
PurposeThe practice of the defects liability period (DLP) is a risk management strategy meant to secure durable and high-quality works. However, construction products continue to malfunction even after the expiration of DLPs. This study seeks to determine the adequacy of DLPs existing in the construction industry and propose appropriate DLPs for construction projects in the Ghanaian construction industry.Design/methodology/approachApplying quantitative research strategy, 124 questionnaires were retrieved from construction professionals surveyed. The data obtained were analysed using descriptive statistics, Cramer’s V and the significance test with the aid of Stata software.FindingsIt was found that defects start showing in both buildings and roads within 12 months after being handed over for the client’s use. The significance test and Cramer’s V analysis indicate low concordance amongst respondents that the 6–12 month DLPs existing in Ghana are adequate. It is found that the existing DLP practice does not provide sufficient security to clients.Practical implicationsConstruction project clients will need to include the tenderer’s proposed DLP as part of the tender evaluation criteria with the objective of picking up a signal of the quality of work to be delivered.Originality/valueThis paper is one of the pioneering studies addressing the issue of the adequacy of DLPs in the construction industry in the Sub-Saharan Africa region. The findings trigger policy and regulatory changes in conditions guiding construction contracts procured in most developing countries that have adopted and adapted to the World Bank Public Procurement Guidelines.
期刊介绍:
The International Journal of Building Pathology and Adaptation publishes findings on contemporary and original research towards sustaining, maintaining and managing existing buildings. The journal provides an interdisciplinary approach to the study of buildings, their performance and adaptation in order to develop appropriate technical and management solutions. This requires an holistic understanding of the complex interactions between the materials, components, occupants, design and environment, demanding the application and development of methodologies for diagnosis, prognosis and treatment in this multidisciplinary area. With rapid technological developments, a changing climate and more extreme weather, coupled with developing societal demands, the challenges to the professions responsible are complex and varied; solutions need to be rigorously researched and tested to navigate the dynamic context in which today''s buildings are to be sustained. Within this context, the scope and coverage of the journal incorporates the following indicative topics: • Behavioural and human responses • Building defects and prognosis • Building adaptation and retrofit • Building conservation and restoration • Building Information Modelling (BIM) • Building and planning regulations and legislation • Building technology • Conflict avoidance, management and disputes resolution • Digital information and communication technologies • Education and training • Environmental performance • Energy management • Health, safety and welfare issues • Healthy enclosures • Innovations and innovative technologies • Law and practice of dilapidation • Maintenance and refurbishment • Materials testing • Policy formulation and development • Project management • Resilience • Structural considerations • Surveying methodologies and techniques • Sustainability and climate change • Valuation and financial investment
