Constructability
Constructability (or buildability) is a project management technique to review construction processes from start to finish during pre-construction phase. It is to identify obstacles before a project is actually built to reduce or prevent errors, delays, and cost overruns.[1]
The term "constructability" defines the ease and efficiency with which structures can be built. The more constructible a structure is, the more economical it will be.[2] Constructability is in part a reflection of the quality of the design documents; that is, if the design documents are difficult to understand and interpret, the project will be difficult to build.[3]
The term refers to:
- the extent to which the design of the building facilitates ease of construction, subject to the overall requirements for the completed building (CIRIA [4] definition).[5]
- the effective and timely integration of construction knowledge into the conceptual planning, design, construction, and field operations of a project to achieve the overall project objectives in the best possible time and accuracy at the most cost-effective levels (CII definition).[6]
- the integration of construction knowledge in the project delivery process and balancing the various project and environmental constraints to achieve the project goals and building performance at the optimal level.(CIIA[7] definition).[8]
Principles
There are 12 principles of construct-ability which are mapped on to the procurement process:[8]
- Integration
- Construction knowledge
- Team skills
- Corporate objectives
- Available resources
- External factors
- Programme
- Construction methodology
- Accessibility
- Specifications
- Construction innovation
- Feedback
