Efficient Construction

For years, construction processes and materials have evolved and are standardized to be more efficient. One of the most used materials in construction, specifically in walls, is brick. Whether concrete or clay, which includes the installation of water pipes, light and / or ventilation becoming one of the most laborious and noisy processes that generate more unusable waste when making the passes. Based on this problem, this research proposes a solution using a brick prototype for efficient construction in water, light and/or ventilation pipe installation issues. This alternative helps reduce labor, costs, sound pollution, element damage, waste, environmental impact and project delivery time, which is the most desired achievement of any contractor.

Project Life

The Architecture, Engineering and Construction (AEC) industries have long sought techniques to decrease project cost, increase productivity and quality, enhance safety, and reduce project delivery time. Building Information Modeling (BIM) offers the potential to achieve these goals. BIM simulates the construction project in a virtual environment. With BIM technology, an accurate virtual model of a facility is digitally constructed. When completed, the computer-generated model contains precise geometry and relevant data needed to support the programming, fabrication, procurement, construction, and post-construction activities. It can be used by project stakeholders for planning and decision making throughout the project life cycle. BIM represents a new paradigm within AEC, one that encourages integration of the roles of all stakeholders on a project. It has the potential to promote greater efficiency and harmony among players who, in the past, saw themselves as adversaries.

Product Service Systems

Extending the lifetime of passive products, i.e., products that do not consume materials or energy during the use phase, by implementing product-service systems (PSS) has a potential to reduce the environmental impact while being an attractive and straightforward measure for companies to implement. This research assesses the viability of introducing PSS for passive products, by documenting five real product cases of prolonging the lifetime through repair or refurbishment and by quantifying, through life cycle assessment (LCA) and life cycle costing (LCC), the change in environmental and economic outcome. The environmental impact (measured as global warming potential over the life cycle) was reduced for all cases because extraction and production dominated the impact. This reduction was 45–72% for most cases and mainly influenced by the number of reuses and the relative environmental burden of the components whose lifetime was prolonged. The costs for the company (measured as LCC from the manufacturer’s perspective) decreased too by 8–37%. The main reason that costs reduced less than the environmental impact is that some costs have no equivalent in LCA, e.g., administration and labor costs for services. The decreases in both LCA and LCC results, as well as the willingness of the companies to implement the changes, demonstrate that this measure can be financially attractive for companies to implement and effectively contribute to a circular economy.

The Cost

The semiconductor industry is a high capital investment industry with the cost of a single completely equipped semiconductor manufacturing facility reaching $2.0 billion. A delay in the operation of the facility can cause the manufacturer a loss of millions of dollars worth of opportunity cost and a share of the market. Thus, semiconductor facility owners want their facilities built quicker, at lower cost, and with higher quality standards. However, the exchangeable knowledge of the project cost and project delivery time associated with the construction of semiconductor facilities nationwide is still in the preliminary stage. One major hindrance to the exchangeable knowledge of the project cost and delivery time is the lack of standard definitions to serve as a base for an industry-wide comparison that will allow owners, designers, engineers, and constructors to make decisions at a very early stage of the projects. The purpose of this research is to overcome the segregation of the existing knowledge in semiconductor facilities construction and to generate benchmarks that can gauge the performance level.

Common Practices

Research studies have discovered that outsourcing has several benefits and the practice is fast replacing in-sourcing especially with regard to construction consultants. In the attempt to examine the benefits of the two approaches on project outcome, this study investigates the influence of the use of in-sourced and outsourced consultants on project performance in Nigeria. The objectives are to determine the use of in-sourcing and outsourcing for selected consultants, compare the use of the two approaches in project delivery and their influence on project performance and compare the performance of projects in which in-sourced and outsourced selected consultants were engaged. To achieve these objectives, a questionnaire design approach was adopted. A field survey involving a sample of 164 projects were selected by stratified random sampling. Data were collected using structured questionnaires and analysed using percentage, mean, Spearman and t-tests. The results of the study reveal that clients engage both in-sourced and outsourced consultants in project development and that the practice has significant influence on project performance. It also discovered that the use of the two approaches has differing benefits on project delivery time and cost. The study concludes that in-sourcing and outsourcing are common practices in project development and that clients are facing a challenge in deciding which approach to adopt. The study also discovers that both approaches has benefits associated with project outcome and suggests that clients should consider these benefits in deciding in-sourced and outsourced consultants.

This study compares the level of project planning on public andprivate sectors projects and its impact on performance. Thepurpose is to create awareness of the level and effectivenessof the planning done by public and private clients in the deliveryof construction projects. A questionnaire survey administeredto a sample of 130 client representatives selected by stratifi edrandom sampling from the population of public and private clientsin the Nigerian construction industry is used and analysed usingdescriptive statistics, the t-test and Spearman correlation test. Theresults show that the level of preconstruction planning on privatesector projects is higher than that of public sector projects whilethe level of contract planning done by the latter is higher thanthat of the former. Furthermore, the performance of private sectorprojects is higher than that of public sector projects in many of theparameters used. However, the level of preparation of life-cyclecharts that concern project delivery time in both public and privatesectors projects is low and the level of project planning in the twocategories of projects has a limited impact on project performance.The understanding of how public and private sectors projectsperform in planning and its impact are expected to assist publicand private clients to know the challenges ahead of them in theireffort to improve the planning and performance of their projects.

Construction projects differ in features and complexity to each passing decade. Therefore, control is a fundamental requirement to avoid overruns of key performance parameters. The study aims to identify influencing factors of management practices and quality of management during construction on project delivery time to mitigate their impact. The inferential statistic was used in the analysis of data for the study. The sample population consists of architects; builders; quantity surveyors; structural engineers, and clients, totalling eighty-eight (88). The metropolitan cities of five provinces constituted the geographical delimitation of the study. The provinces are Eastern Cape; Free State; Gauteng; KwaZulu-Natal, and Western Cape, while the metropolitan cities are Bloemfontein; Cape Town; Durban; Johannesburg, and Port Elizabeth. The probability sampling method was employed in the selection of architects, South African property owner's, and masters builders. While stratified sampling was used for quantity surveyors. A questionnaire survey was conducted among these stakeholders in the Building Construction Industry to access influencing factors of management style and quality of management during construction. Finding relative to management style include that set time limits, specify goals people are to accomplish and require regular reporting on progress and for quality of management during construction are effectively coordinating resources, developing an appropriate organizational structure to maintain workflow influences project delivery time  In most cases these tradesmen require supervision construction, which results in delay and attending, may drastically reduce delay on projects. Based on the finding of the study, ways to mitigate poor management style and quality of management during construction were suggested.
