dc.description.abstract | Construction is a large, dynamic, and complex industry sector that plays an important role in the Kenyan economy. Building regulations are statutory instruments that seek to ensure that the building policies set out in the relevant legislation are carried out. Building regulation involves registration of contractors, projects, skilled construction workers, construction site supervisors, training institutions, and provisions relating to collection and payment of the construction levy. This study aimed to establish the influence of regulatory framework on the performance of building construction projects in Nairobi City County, Kenya. The study was guided by the objectives; to establish the influence of the Board of Registration for Architects and Quantity Surveyors on performance of building construction projects in Nairobi County, to determine the influence of County Government of Nairobi regulations on performance of building construction projects in Nairobi County, to establish the influence of National Environmental Management Authority regulations on performance of building construction projects in Nairobi County and to determine the influence of National Construction Authority regulations on performance of building construction projects in Nairobi County. The study adopted a descriptive survey research design. The study used simple random sampling to select 19 licensed quantity surveyors, 28 licensed architects and 132 licensed building contractors operating in Nairobi. The study found out that Architects and Quantity Surveyors trained and licensed in the planning and designing of buildings, their work is to advise his clients and study their needs, Nairobi County had formulated a statutory and regulatory framework to embrace digital system for management of developments applications which involves the public and stakeholders in policy formulation, NEMA effectively implements environmental policies, proposes effective mitigation measures for significant negative impacts of building construction projects and NCA registers and certifies constructors, regularly publishes the code of conduct for the building construction industry. The study concludes that a regulatory framework in which regulators challenge firms to improve based on constructive and active engagement can be effective in ensuring compliance before a serious problem emerges and regulatory framework governing the construction industry could seek legal capacity to prosecute errant developers. The study recommends that the composition of the regulatory framework that governs the Kenyan construction industry should include specialized bodies mandated to champion for regulations in order to streamline the building industry in Nairobi and NEMA could carry out environmental audit of all activities that are likely to have significant effect on the environment during the course of executing the project | en_US |
