Life cycle carbon emissions (LCO2), made up of operational and embodied carbon, have become a major metric of building environmental performance and energy efficiency. Whilst there are now standard methods for operational carbon assessment due to its significance in LCO2, there is still less emphasis on embodied carbon counting. However, the relative contribution of embodied carbon is on the rise as buildings become increasingly energy efficient. Following the rule that only something which is m...

The construction sector (CS) is an economic barometer that mirrors the state of the economy. Therefore, the construction sector is susceptible to economic impacts. This study investigated the impact of economic shocks (measured with the Gross Domestic Product (GDP)) on construction sector performance. The study used econometric methodology which involves several sequential procedure including unit root test, cointegration test, causality and exogeneity tests. The data used was the Annualized tim...

Principal-agency problems due to hidden incentives might be amplified, for example, under circumstances when unjustified trust in an inspector is associated with higher perception of building quality. This paper sets out to determine whether a significant difference exists in the owner’s perception of the building quality based on the perception of the inspector and the inspection process within multi-dwelling housing. A principal-agent theoretical perspective and the question of trust is applie...

Design-build contracts with performance-based specifications are believed to raise productivity and the innovation rate. Such specifications for highway and bridge contracts may create risks, be too detailed or difficult to verify. The purpose has been to analyse how performance-based requirements are used in Swedish design-build contracts for highway projects. How contractors are encouraged to provide innovative technologies is emphasized. Generic documents from the Swedish Transport Administra...

Transportation infrastructure contributes to the development of an economy. However, the performance of such infrastructure is hampered if sustainability elements are not considered at the initiation/conception and operation stages of the projects. The study aimed to validate a structure of transportation project sustainability measures to evaluate projects and ensure continual delivery of intended benefits in the long run. Empirical data were collected using a field questionnaire survey develop...

The issue of whether contracts promote innovation and sustainability is an important but overlooked aspect for achieving energy and environmental targets, as well as for creating smart and sustainable cities. In this article, based on the principle/agent problem and Holmstrom and Milgrom’s work on optimal contracts it is argued that the current general conditions of architectural and engineering consulting agreements in Sweden (ABK 09)—a standard type of contract often used in developer/consulta...

Communication management is viewed as an imperative factor associated with performance improvement in construction projects. In Eswatini, it is established that projects experience poor project delivery associated with poor communication management practices. This study seeks to elucidate communication management practices informed by local culture and relate it to project outcome. A questionnaire survey of practitioners registered with Eswatini construction industry council was adopted for the ...

A comprehensive review of megaproject performance propositioned the issues leading to project failure as behavioral. Project failure linked cost overruns and schedule delays to acts of delusion and deception, citing the ability to learn lessons, and the misalignment of incentives as influencing factors. A mixed-methods study was designed to gain insight into the decision-making behaviors of undergraduate civil engineers, and the role that education could play in enhancing decision-making. A co-c...

The characteristics of a project that makes it hard to understand, predict, and manage its general behavior despite the availability of required information relating to the project dynamics is referred to as project complexity. A good knowledge of project complexity at the construction phase of a project, as well as a well thought out plan to manage complexity will determine how proficiently construction projects are planned, managed, and executed in an environmentally friendly manner. The level...
