Industrial project constructability improvement

Constructability is defined as the ability of project conditions to enable the optimal utilization of construction resources. Constructability improvements may heighten the construction-sensitivity of designs, render the communication of engineering information as more effective, optimize construction originated construction techniques, increase the effectiveness of construction management policies, improve vendor/subcontractor services, or identify needs for designer-constructor communication during the project. Constructability improvement ideas collected on a large refinery expansion project are analyzed for content, and classification frequencies are observed. Analysis of engineering rework exposes the causes and costs of rework that occurs as a result of constructability problems.
