Abstract

Purpose

This study aims to lay the groundwork for the potential application of value management (VM) in construction projects. This paper presents a critical review on the status of VM in a developing country and highlights the role of perceptions on critical success factors (CSFs) for the phases of VM studies, as the participants in a VM study should consider CSFs tailored to the local context.

Design/methodology/approach

A series of interviews and a questionnaire were conducted to understand the drivers, perceptions, barriers, and CSFs of VM in the Jordanian construction industry. Although descriptive statistics were used to analyze the status of VM, a structural equation modeling (SEM) approach was adopted to highlight the interrelationships between perceptions and the CSFs of the three phases of VM (i.e. pre-workshop, workshop, and implementation).

Findings

The descriptive analysis revealed conflicting viewpoints for perceptions and drivers. Most practitioners acknowledged little awareness of VM phases, and the SEM results indicated that perceptions of VM, in terms of its capacity in improving the scope and objectives of the project, and reducing overall costs, most strongly influenced the CSFs of the implementation phase in terms of support and clear plan for implementation, and had the least influence on the pre-workshop phase. Further, the perceptions had a moderate effect on the CSFs of the workshop phase and it tended to be positive, highlighting the importance of function analysis in this phase.

Originality/value

This is the first study to reveal the status of VM in Jordan in terms of adoption, drivers, perceptions, barriers and CSFs; no prior studies have investigated how perceptions can affect the CSFs of each phase of VM and the endorsement of VM by the construction industry. The contributions of this study include linking the perceptions of construction professionals with the CSFs of VM.

Abstract

Purpose

Skewed pricing is a typical tactic used by tenderers in unit price projects to gain additional advantages at the expense of the owner or other competing tenderers. This paper aims to describe the development of a model for detecting skewed pricing in competitive tendering for unit price contracts.

Design/methodology/approach

The model evaluates how much the offered unit rates for work items deviate from the reasonable rate identified from the item’s submitted unit rates. Item rate deviations are integrated into a total deviation score for each submitted tender based on the relative weight of the work item to the total project amount. The model allows for assigning higher weights to work items that are more prone to skewed pricing, such as those that are performed early and those that are expected to experience quantity fluctuations.

Findings

The paper presents a detection model that uses only the submitted prices of the competing tenderers to perform the needed calculations, which reduces subjectivity in identifying skewed tenders. Two examples are given to demonstrate how the model may be used to detect skewed tenders.

Originality/value

The model supports tendering officials in the challenging task of identifying skewed tenders, which is required by rules and regulations governing public procurement. The model’s ease of use is expected to make it more widely used as a decision-support tool during the tender evaluation stage of real-world projects.
