Constructability

Constructability (or buildability) is a concept that denotes ease of construction. It can be central to project management techniques to review construction processes from start to finish during pre-construction phase. Buildability assessment is employed to identify obstacles before a project is actually built to reduce or prevent errors, delays, and cost overruns.[1]

CII defines constructability as “the optimal use of construction knowledge and experience in planning, design, procurement, and field operations to achieve overall project objectives”.[2]

The term "constructability" can also define the ease and efficiency with which structures can be built. The more constructible a structure is, the more economical it will be.[3] 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.[4]

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 [5] definition).[6]
  • 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).[7]
  • 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[8] definition).[9]
