The Critical Path Method (CPM), the Last Planner System (LPS) and location-based methods, such as the Line of Balance (LB), are discussed extensively in the technical literature about schedules. However, no discussion exists focusing on the differences and similarities of these methods in terms of their use in different countries. Using chi-squared...
Article
Collaborative scheduling (CS) and related practices impact the performance of construction projects which can be measured by key performance indicators (KPIs). However, little is known about which of these practices are implemented and how their combined implementation might impact KPIs. The objectives of this research are to identify perceptions o...

The design of environmentally-friendly buildings relies on the work of interdisciplinary teams who have to look at problems in a holistic way. Teams need to communicate, collaborate, and make decisions not solely based on first cost considerations. For this purpose, Target Value Design (TVD) related practices are being used to deliver green buildin...
Conference Paper
Construction contracts play a vital role in construction projects and, in many ways, have the power to: promote and reward behaviors that support the delivery of successful projects; engage participants in the pursuit of what is best for the project and not only for individual parties; and even define how projects will be run and which tools will b...

Purpose This paper investigates the impact of defects on the satisfaction of residential construction customers. Three working hypotheses were tested: 1 – Defects in residential construction impact the customer satisfaction; 2 – Different defects have different impacts on customer satisfaction; and 3 – Interviewing customers about defects in their...
Article
An alternative to the traditional way of designing projects is the process of target value design (TVD), which takes different departure points to start the design process. The TVD process starts with the client defining an allowable cost that needs to be met by the design and construction teams. An expected cost in the TVD process is defined throu...

A way to better comprehending the production strategy is by looking at it from two complementary perspectives: content and process. However, most research papers tend to focus on the content of a successful production system while few explore the process in which it was developed. Because lean construction literature is no different, this paper aim...
