Purpose The purpose of this paper is to compare the performance levels of small scale local government contractors (SSLGCs) in northern part of Nigeria with international practice. Previous studies focused attention primarily on benchmarking the performance of contractors, but were mostly conceptual rather than from empirical findings. This continuous to pose a challenge to the sustainable development of the construction industry, particularly, in developing countries like Nigeria. There is therefore a need to identify, assess and compare performance practice levels of small scale contractors. Design/methodology/approach The performance of each contractor was evaluated using a five-point Likert scale used in obtaining mean performance levels in respect to three classes of performance practices. A questionnaire survey was administered to major parties in the industry; clients, contractors and consultants who were selected by using a proportionate stratified random sampling technique. The contractors’ performance was compared by using ANOVA with post hoc. Findings The results indicated that the SSLGCs in Nigeria were average performers and there were effects and differences among the various contractors’ levels of performance with international practice. Research limitations/implications The study is limited to SSLGCs in northern part of Nigeria. Practical implications The study provided the criteria for evaluation of SSLGCs’ performance in Nigeria and other developing countries that faced similar problems. Social implications The study created bases for self-evaluation and competition among small scale contractors in Nigeria for the enhancement of productivity particularly in rural areas and general national development. Originality/value This study emanated from the governmental reports and past researches in the area of performance management on the persistence of the poor performance of small scale contractors in construction industry.
Building Information Modelling (BIM) has been emerged to streamline the construction process by addressing interdisciplinary inefficiencies that have been rooted in the industry over the decades. However,Malaysiaconstruction industry is having barriers and difficulties in BIM adoption as there is no clear guidance and best practices in BIM implementation that can be learnt by them. The purpose of this research is to increase the awareness of BIM implementation towards enhancing the efficiency and productivity of architecture firms. BIM implementation requirements which cover management, process, people and technology were investigated through a total of 285 structured questionnaire surveys that distributed to professional or/and graduate architects at management and operational level. The overall severity of BIM implementation requirements were then established and ranked in conjunction with their perceived levels of importance and frequency of occurrence. Results indicate that the current low BIM status denominated among architectural practices in Malaysian construction industry. Predominantly attributed to the interoperability of BIM, selection of BIM tools, employment of pilot project, risks management and development of guidelines and standards that categorised under the management and process.
Abstract:The technical performance requirements of projects posed a challenge to the sustainable development of small size local government projects particularly in developing countries. Studies in the past focused mainly on the performance of major foreign construction firms mostly owned and operated by expatriates. Very few researches however, have been conducted to assess the relationship between major cost factors affecting technical performance of small size local government projects. This study is aimed at assessing the relationship between major cost factors that affect technical performance of small size local government projects in Nigeria. Survey instruments were administered to major stakeholders in the construction industry comprising of project clients, contractors and consultants using proportionate stratified random sampling method. A Warp partial least square-structural equation modeling (PLS-SEM) software algorithm was used for the analysis of collected data. The software is one of the powerful software for data analysis and has an advantage of providing p values based on the structure of the research model. The study concluded that cash flow problem, fraudulent practice and nature of construction environment are the major factors affecting technical performance of local government projects in Nigeria and further recommended the use of mediator variables like pay for performance and advance payment policy to minimise such negative effects. Governments in developing countries should devise a good cash flow policy and impose stringent penalties against any party involved in fraudulent activity.
Construction of high-rise buildings, large-scale apartment blocks, or construction in urban areas demands increasingly greater use of cranes. In the construction industry, the use of crane is common and very important regardless of the size of the project. Cranes generally use cable and pulley to deliver a mechanical advantage when it is necessary to lift heavy loads. They have the potential to move materials of different sizes that play an extraordinarily important role in the construction site. The crane operator is responsible for controlling the crane effectively and follow the safety guidelines. Life loss, injury, and property damage are the implications that will occur if the crane maintenance specifications and operations are not correctly practiced. As the result of crane accident happened every year, this paper seeks to identify the causes of crane accident at construction sites in Malaysia. With the aim that has been stated, this paper summarizes statistic and causes of crane accident of most cited papers. Thus, the causes that lead to accident from previous researcher will be highlighted. Outcomes from the study demonstrate that operational and technical problem are the major causes of crane accidents at construction site in Malaysia. Exploration of this paper will help the construction industry especially in crane monitoring for a better safety performance and regulation at all construction projects.
