Abstract
The study examined how the influence of sustainable construction practices enhances timely delivery of building projects in Port Harcourt, Rivers State Nigeria. A descriptive survey research design was adopted. The study population comprised 620 building professionals, including project managers, architects, site engineers, quantity surveyors, and construction supervisors working with registered construction firms. A census method was used, involving the entire population. Data were collected using a questionnaire. The instrument contained 20 items grouped into four clusters and was structured on a four-point rating scale. It was validated by three experts in Building Technology and Measurement and Evaluation. A pilot test conducted with 30 professionals yielded reliability coefficients of 0.84, 0.88, 0.86, and 0.90 across the clusters, with an overall reliability of 0.87. Of the 620 questionnaires distributed, 593 were retrieved and found valid. With respect of the data analysis, Mean and standard deviation were utilised by this study for the analysis of the research questions, and the study hypothesis were tested by the use of regression analysis. Based on the results of this study, a sound project planning, a careful management of resources and also environmental compliance play a greater role in making sure construction projects are successfully delivered on time. In view of these, it is important to note that management of resources was seen as the most essential factor, before environmental compliance and project panning. Based on the findings, the study recommends that professional regulatory body should ensure they conduct regular oversight on environmental assessments and making sure they become active tools for transparency and accountability. With respect of the project managers, it is vital they identify risk during the inception stage of the construction phase, ensuring that the planning of the project work comes to fruition. Implementing a good system for resources tracking will help to mitigate delay in building projects.
Keywords: construction project delivery, sustainable construction practices, building projects, project planning, environmental compliance.
1. Introduction
A successful delivery of construction projects will help to enhance project efficiency and effectiveness and also enable various construction professionals to meet up construction project deadlines. Prior to this time, sustainable construction practices have moved from becoming more than mere trend to being important part in which construction projects are successfully planned, monitored and executed. It entails a balance between the growth of the economy, taking proper care of the built environment and ensuring the peoples responsibilities and the communities at large. The term social responsibility with respect to sustainable construction entails searching out for the people who reside with meaningful results. With respect of the practice of sustainable practices, envelope a broader range of methods which main aim is to use available resources judiciously, mitigating environmental destruction while ensuring that the work is executed on time without reducing project quality.
It comprises choosing long lasting materials such as higher –performance concrete that are not preserve resources rather assist to mitigate a very longer- term preservation with respect to needs (Eze et al., 2021). Attempt to diminish environmental footmark will lay hold of too many forms, with respect of making use of renewable vitality for installing water saving plumbing, recycled residue materials instead of conveying them to toxic waste site (Ogunmakinde et al., 2022).In view of the practical support, building information modelling which is a technological tool that enables various construction stakeholders for project planning, design, coordination and to enhance construction project delivery more effectively and efficiently. In view of transparent supervision and also not many shocks, project teams are usually prepared at all costs to execute work at the agreed time and also ensure they reach expected standard (Akinosho et al., 2020).When there much delay project execution, misallocation of resources and also in view of sidestep environmental regulations is an issue which has becomes so common and thereby hindering the execution of project (Oke, Aigbayboa, & Ngowi, 2021).
Thus, this study looked at the influence of sustainable construction practices on timely delivery of building projects in Port Harcourt metropolis. To achieve the main goal of the study, the specific objectives of this study are: to evaluate the influence of environmental compliance on timely delivery of building projects; examine the influence of efficient project planning on timely delivery of building projects; and the investigate the influence of efficient resource management on timely delivery of building projects in Port Harcourt metropolis. The study also made use of null hypothesis which were tested at 0.05 level of importance with respect of the three objectives.
