Examination of Job-site Layout Approaches and their Impact on Construction Job-site Productivity

In all forms of construction project delivery, job-site layout is routinely developed and designed after bid award and prior to the contractors' receipt of the notice to proceed or letter of commencement. Job-site layout decisions are made to locate temporary offices, sanitary facilities, worker rest areas, crane locations, storage and workshop areas, access points and access roads, utilities and other critical features. These jobsite design decisions affect the operational capabilities of the site and have a direct influence on both the costs and schedule through productivity. This paper will examine the various approaches utilized in practice and proposed through research for jobsite layout design and site optimization. Factors and variables considered in the identified approaches are discussed and evaluated with respect to the impact on jobsite productivity and successful contract delivery. Important factors for job-site layout are further explored through a survey of working professionals within the United Arab Emirates (UAE). Survey results are summarized, examined and discussed in relation to the variables and critical parameters identified and their effect on job-site performance and contract success. The paper concludes with a discussion of future directions for job-site benefits.
