Quantitative Comparison of Project Performance between Project Delivery Systems

Journal of Management in Engineering · 2020 · 55 citations

A project delivery system (PDS) defines the relationship and timing of involvement between different contracting parties in construction. Using data from 109 projects, this paper statistically investigates the project performance of the four main PDSs: design-bid-build (DBB), construction management (CM), design-build (DB), and integrated project delivery (IPD). First, descriptive statistical methodologies were applied to the dataset to determine performance benchmarks for each examined PDS. Nex…

Augmented Reality in the Construction Industry: Use-Cases, Benefits, Obstacles, and Future Trends

Frontiers in Built Environment · 2022 · 51 citations

Information is the lifeblood of modern construction. Advances in Information and Communication Technology have been and are continuing to progress at rapid rates. Construction companies that are successfully able to adopt and integrate new technologies will gain a competitive edge. One emerging technology that has great potential to transform the construction industry is Augmented Reality (AR). While AR has been of interest to researchers for some time, no single research effort has yet comprehe…

Defining the Success Status of Construction Projects Based on Quantitative Performance Metrics Thresholds

Journal of Management in Engineering · 2022-11-30 · 18 citations

Despite the high spending and high employment, the construction industry struggles to agree how to go about project performance assessment and what constitutes a successful project. This does not allow stakeholders to address the issues in and drawbacks of their respective projects. Hence, this research outlines performance metrics upper limits, which can be used in defining a successful project. Data were collected from Construction Industry Institute (CII) members and multiple construction fir…

Comprehensive Model for Construction Readiness Assessment

Journal of Management in Engineering · 2020-09-18 · 15 citations

The construction industry has experienced rapid growth in the last decade, which was not paralleled by a corresponding growth in productivity. A major reason of this stagnant productivity is that project teams often rush into construction without adequately assessing construction readiness. As a result, numerous projects start construction before they are ready to do so, leading to frequent interruptions, rework, out-of-sequence work, delays, and other complications, resulting in poor productivi…

Developing a Rating Score for Out-of-Sequence Construction

Journal of Management in Engineering · 2020 · 14 citations

Out-of-sequence (OOS) construction takes place when an activity or series of activities is not performed according to baseline planned logical productive sequencing. A previous expert-based study by the authors—which has already been published—was the first to provide an industry-wide assessment of OOS work that identified 88 causes of OOS work and quantified them in terms of likelihood of occurrence, relative impact, and risk rating. This paper moves forward to create OOS risk tiers and OOS rat…
