ABSTRACT
The study examined the impact of the constraint factors on building projects delivery in Enugu State, Nigeria and suggested possible ways to mitigate the impact in order to deliver successful sustainable building in the state. Nine local government areas (three each from the three senatorial zones of the state) were sampled based on urbanization and population of inhabitants in the area. A total of four hundred (400) questionnaires were distributed to stakeholders in the built environment while three hundred and forty-four (344) representing 86.0% of the respondents were returned and used for the analysis. The data was analyzed using common size percentage analysis, mean score using five-point Likert rating scale, severity index/ranking, regression and correlation analysis. The results show that Database for building projects and streamline procedure to implement sustainability of building projects ranked first among the factor variables with mean score of 4.69 and severity index of 93.7% followed by un-built areas as indicated in the site plans need further landscape deign to achieve sustainable development. The least in the ranking was inadequate provision for protection of existing and future environmental issues in the master plan for proper enforcement. The work concluded that the sustainable development concepts applied to design, construction operation and maintenance with whole life assessment of buildings can enhance the economic welfare, environmental health and social well-being of communities in Enugu state. The study recommended the creation of database for sustainable building projects, articulation of strategies by liaison with existing agencies/stakeholders and legislation to back up all the recommendations for proper enforcement.
Keywords: Sustainable buildings, sustainable design and construction, impact factor variable, sustainability.
1.0 INTRODUCTION
Construction is one of the largest industries in both developing and developed countries in terms of investment, employment and contribution to Gross Domestic Product (GDP) of any Nation. Its impact on the environment is considerable particularly in areas of energy use, soil degradation, loss of agricultural land, forests and wild lands, air and water pollution, and depletion of non-renewable energy sources and minerals (Ametepy, Ansah and Gyadu-Asiedu, 2020). The construction industry accounts directly and indirectly for nearly forty percent (40%) of material flow entering the world economy (Clement, Cheng and Hong, 2018); and in developing countries for around fifty percent (50%) of the total energy consumption (Ametepyet al., 2020; Ibrahim and Price, 2005).
Aluko (2011) stated that, in Nigeria, many laws and regulations were enunciated at Federal, State and Local government levels for proper planning of the environment and building design architecture without integration of sustainability concepts. Most of the building projects are not sustainable which portends danger to the environment by degrading the natural design architecture. Although the principal indicators for sustainable development are not integrated at the planning stage for most building projects, their execution also lack proper monitoring by the policy makers (Udegbunam, Agbazue, and Ngang, 2017). These led to poor implementation during construction which drastically affects our living environment. Broman and Roberts (2017) assert that it is important to minimize the consumption because as material is consumed its chances for future use are diminishing; hence, its potential utility to future generation is lost. Embracing green or sustainable concept in design is aimed at reducing energy consumptions, operation and maintenance cost, reduce building related illness, increase the productivity and comfort of building occupants, reduce waste and pollution, increase building and component durability and flexibility. There is the need to integrate these at early stages of building, planning and construction process. However, sustainable development for building project delivery needs time, understanding, acceptance, adjustment and implementation. These can be achieved through awareness/commitment both on the part of individuals, community and professionals.
The transformation of sustainable construction policy into project level practice, are the non-technological institutional processes, which are dependent upon the industry structure, communication channels and the organization and strategic orientation of its constituent actors (Rohracher, 2001). The uptake and implementation of sustainable construction requires decision processes that are integrated across various project level interfaces demarcated by different phase of the construction life cycle. However, the challenging task may stem from the fragmented nature and complexity of the construction sector (Myers, 2005), the multi-dimensional nature of sustainable construction, the lack of a structured methodology and lack of information at various hierarchical levels (Ugwu and Haupt, 2007).
