Introduction

The increasing levels of competition and the introduction of manufacturing concepts within the industry led to specialization. Such specialization led to the separation of design and construction facilities. The increasing complexity of many projects makes it more and more difficult for the designers to be fully aware of all the implications of their designs on the construction costs. With the problems associated with in separated design and construction continuing to grow, industry began implementing value engineering and construction management services, recognizing the benefits of constructor's involvement during planning and design phases to reduce project life cycle cost.

Constructability is an approach which links design and construction processes, which have traditionally been isolated in industry. Making use of construction knowledge, from the earliest stages of a project where the ability to influence cost is at greatest, makes sense from both practical and financial viewpoints. Constructability enhances the quality of constructed facility by better communication among major project participants such as design, engineering and construction professionals. Better communication among these participants reduces the project failure & other related problems.
