'''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 overrun]]s.<ref>The Institution of Professional Engineers New Zealand Incorporated (IPENZ). [http://www.ipenz.org.nz/ipenz/forms/pdfs/PN13_Constructability.pdf Constructability.] {{webarchive|url=https://web.archive.org/web/20111018114621/http://www.ipenz.org.nz/ipenz/forms/pdfs/PN13_Constructability.pdf |date=2011-10-18 }} ''Practice Note 13.''

[[Construction Industry Institute|CII]] defines constructability as “the optimal use of construction knowledge and experience in planning, design, procurement, and field operations to achieve overall project objectives”.<ref>[[Construction Industry Institute]] (1986). [https://www.construction-institute.org/constructability-a-primer ''Constructability: A Primer'']. Research Summary 3-1.</ref><br />
<br />
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.<ref>{{Cite magazine |url=https://www.aisc.org/globalassets/modern-steel/archives/2011/03/2011v03_tips_for_design.pdf |title=Tips for Designing Constructable Steel-Framed Buildings |last=Schwinger |first=Clifford W. |magazine=Modern Steel Construction |date=March 2011 |access-date=April 30, 2019}}</ref> 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.<ref>{{Cite web |url=http://www.cpwr.com/sites/default/files/publications/krgambatese.pdf |title=Investigation of the Viability of Designing for Safety |last1=Gambatese |first1=John A. |last2=Hinze |first2=Jimmie |last3=Behm |first3=Michael |publisher=CPWR - The Center to Protect Workers' Rights |date=May 2005 |page=5 |access-date=April 30, 2019 |archive-date=March 4, 2016 |archive-url=https://web.archive.org/web/20160304055205/http://www.cpwr.com/sites/default/files/publications/krgambatese.pdf |url-status=dead }}</ref><br />

The term refers to:<br />
* the extent to which the design of the building facilitates ease of construction, subject to the overall [[requirements]] for the completed building (CIRIA <ref>Construction Industry Research and Information Association</ref> definition).<ref>McGeorge, Palmer & Kerry London. [https://books.google.com/books?id=EEp6a1AuirUC&q=Construction+management:+new+directions ''Construction management: new directions''], 2nd ed. Blackwell Science, 2002, p. 54.</ref><br />
* 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-effectiveness analysis|cost-effective levels]] (CII definition).<ref>[[Construction Industry Institute]] (CII), based at [[The University of Texas at Austin]]. [https://www.construction-institute.org/search?filters=Best+Practice-Constructability CII Best Practices: Constructability]</ref><br />
* the integration of construction knowledge in the project [[Service delivery framework|delivery]] process and balancing the various [[project]] and environmental constraints to achieve the project [[goal]]s and building [[performance]] at the optimal level.(CIIA<ref>Construction Industry Institute, Australia.</ref> definition).<ref name=Singh >{{cite book |last=Singh |first=Amarjit |title=Creative Systems in Structural and Construction Engineering |publisher=Balkema |year=2001 |pages=96, 97 |isbn=9058091619}}</ref><br />
