Managing a $2 billion dollar construction program requires a unique application of tried and true control systems and provides an opportunity to innovate new methods. The Program utilizes...
Project Controls on the Channel Tunnel Project
Establishing controls for a multi-facted, multi-billion dollar, privately financed, project which is run by two organisations created solely for that one project has been a major challenge....
Conceptual Model for a Site Operations Control System
This study discusses a conceptual model for designing an on-site management control system. Capabilities of this proposed Site Operations Control System (SOCS) include a mechanism for...
Partnering: Contracting for Quality
The concept of partnering is an approach to conducting business that confronts the economic and technological challenges confronting the U.S. Construction Industry in the 1990's....
Determining the Optimum Level of Quality Management Effort
Quality management is an essential factor in construction project success. Determining the appropriate level of quality management effort remains a challenging managerial decision. A discussion...
Construction Inspection Responsibility from the Viewpoint of a General Contractor and Construction Manager on a GMP Project
Absent local laws to the contrary, any member of the construction team, the Owner, Architect, or Contractor, can theoretically arrange for and provide any testing and inspection that may...
Contractor Inspection
Partnering between the owner, architect-engineer (A-E) and construction contractor creates an environment which facilitates the successful completion of quality construction. Each participant...
Integration of CAD and Material Control
The purpose of this paper is to address the relationship between CAD (Computer Aided Design) drawings and the material control software. Computer generated drawings have the ability to...
Smart Exception Reporting
Project control systems that contain a degree of 'intelligence' are possible with today's technologies. At the same time project controls engineers...
Integration of Cost and Schedule Control
This paper presents cost control and schedule control relationships in an integrated manner for an activity/cost account that has a single output scheduled to be produced in a linear,...
