Over time, the construction industry’s development has been constantly questioned due to low productivity, high energy consumption, generation of wastes, and greenhouse gas emissions. According to a recent United Nations Environment Program report, building and construction account for 36% of global energy use and 39% of energy-related carbon dioxi...

The adoption of integrated project delivery (IPD) provides several advantages over traditional delivery methods, such as shorter schedules, efficient communication, and higher performance quality. However, its implementation is constantly hindered by many barriers. Existing studies on IPD barriers are limited to quantifying and addressing such obst...

In qualifications-based selection (QBS), consultants are selected according to their competencies rather than price. However, clients are often apprehensive about the subjectivity associated with implementing QBS because non-price criteria are hard to measure. In addition, there is no complete set of all relevant consultant evaluation criteria esta...

One of the most critical elements in the construction industry is the materials used in the structure. The selection of appropriate materials can significantly impact cost, durability, beauty of the building, and many other aspects. Given the importance of sustainable development, it is necessary to carefully examine all the sustainability dimensio...

Author Malcolm Gladwell argues in both his bestsellers books The Tipping Point and Outliers that extreme intelligence is not exclusively responsible for success. Neither is giftedness. One could be extremely gifted, but if the surrounding environment is not supportive, no greatness would be achieved and no endeavor would be successful. Most importa...

In recent years, the performance of the construction industry has highlighted the increased need for better resource efficiency, improved productivity, less waste, and increased value through sustainable construction practices. The core concept of sustainable construction is to maximize value and minimize harm by achieving a balance between social,...

Purpose Existing labor estimation models typically consider only certain construction project types or specific influencing factors. These models are focused on quantifying the total labor hours required, while the utilization rate of the labor during the project is not usually accounted for. This study aims to develop a novel machine learning mode...

Selecting the appropriate Project Delivery Method (PDM) for a project can influence a project’s success significantly. No one PDM is the perfect option for all projects. The most suitable PDM should be chosen based on specific requirements, characteristics, and success factors of the project. Design-bid-build (DBB), Design-Build (DB), and construct...

Cost overruns, schedule delays, claims, and disputes are regularly faced issues in most construction projects. While the reasons are numerous, one common cause is inappropriate selection of the project delivery method. Founding a project on an inappropriate delivery method not only disrupts schedule and cost plans, but also wrecks professional rela...

Efforts to improve the sustainability of the building construction sector have tended to focus on reducing operational energy cost, whereas sustainability considerations in the material selection at the design and construction phase have received less attention due to construction budget constraints. The present study proposes a decision support sy...

According to the construction leadership council: “smart construction is building design, construction, and operation that through collaborative partnerships makes full use of digital technologies and industrialized manufacturing techniques to improve productivity, minimize whole life cost, improve sustainability and maximize user benefits” [1]. So...

The selection of Architect/Engineer (A/E) is one of the critical decisions made by owners early in a project. Given that architects and engineers are not commodities; therefore, the assessment of A/E firms should be based on their qualifications. This paper attempts to quantitatively assess and understand the effects of A/E capabilities on project...

Sustainable construction aims to minimize harm and maximize value by achieving a balance between social, economic, technical, and environmental aspects, commonly known as the pillars of sustainability. In recent years, the construction industry has drawn increasing criticism due to its low productivity and high rates of energy consumption, generati...

Accurate labor resource allocation ensures that tasks are assigned to the most suitable individual(s) and the optimal number of staff are available to complete certain tasks, making it essential for the success of construction projects. This study proposes a methodology for forecasting labor resource requirements for upcoming projects using data mi...

Design in nature is an iterative and interdependent process. Previous research shows that in some projects, 50% of this process contains waste. The Last Planner System (LPS) proved its efficiency in planning and controlling the execution phase. However, due to the nature of the design process, implementing LPS at this stage contains many constraint...

Among the critical factors of project success is the proper selection of qualified contractors. More owners are adopting Best Value (BV) procurement which combines the technical qualifications with fee proposals to rank bidders. However, the successful application of BV depends on two integral factors: ranking of contractor's qualifications using m...

Winning a bid is a good opportunity for contractors that includes risks. After winning a project, contractors typically receive payments after two-three months of work completion that leads to negative cash flow (overdraft) throughout the duration of a project. Hence, contractors borrow from banks and pay monthly interests on the amount of overdraf...

Purpose: The bid/no-bid decision is critical to the success of construction contractors. The factors affecting the bid/no-bid decision are either qualitative or quantitative. Previous studies on modeling the bidding decision have not extensively focused on distinguishing qualitative and quantitative factors. Thus, the purpose of this paper is to im...
