Pre-engineered and prefabricated buildings ordering guide

Purpose

The purpose of this page is to create a comprehensive ordering guide that assists ordering agencies, particularly contracting officers, to effectively use the Multiple Award Schedule to purchase total solutions for pre-engineered/prefabricated buildings. This ordering guide is not a stand-alone reference — it is recommended that you also become familiar with the MAS Desk Reference Guide and Federal Acquisition Regulation 8.4 Federal Supply Schedules. This Ordering Guide may be revised from time to time.

What are pre-engineered/prefabricated buildings?

The most widely used form of prefabrication in building and civil engineering is the use of prefabricated concrete and prefabricated steel sections in structures where a particular part or form is repeated many times. Modular Construction can be considered a form of Prefabricated Construction.

Precast is a construction product (mostly concrete) produced by casting concrete in a reusable mold or “form” which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site-specific forms and cured on site.

Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out.

The term prefabrication also applies to the manufacturing of things other than structures at a fixed site. It is frequently used when fabrication of a section of a machine or any movable structure is shifted from the main manufacturing site to another location, and the section is supplied assembled and ready to fit. It is not generally used to refer to electrical or electronic components of a machine, or mechanical parts such as pumps, gearboxes and compressors which are usually supplied as separate items, but to sections of the body of the machine which in the past were fabricated with the whole machine. Prefabricated parts of the body of the machine may be called ‘sub-assemblies’ to distinguish them from the other components.

The most widely used form of prefabrication in building and civil engineering is the use of prefabricated concrete and prefabricated steel sections in structures where a particular part or form is repeated many times. It can be difficult to construct the formwork required to mold concrete components on site, and delivering wet concrete to the site before it starts to set requires precise time management. Pouring concrete sections in a factory brings the advantages of being able to re-use moulds and the concrete can be mixed on the spot without having to be transported to and pumped wet on a congested construction site. Prefabricating steel sections reduces on-site cutting and welding costs as well as the associated hazards.

Pre-engineering is the practice of designing a building and compiling materials to be assembled onsite. It removes the need for a contractor to source materials from multiple suppliers, as the materials will arrive onsite as a package with a plan set explaining assembly, similar to a child’s building block kit. An important difference to note is that the pre-engineered building requires on-site construction.

Benefits of pre-engineered/modular buildings compared to conventional construction

Modular vs. conventional construction:

A modular building is a pre-engineered structure that is flexible enough to satisfy virtually any requirement. It is usually tougher than standard drywall construction as well as its ability to be expanded, relocated, reusable, and recyclable. The primary advantage of modular/pre-engineered buildings over conventional construction is that they can save up to 35% on initial construction costs such as labor and materials.

Applications:

Office buildings, training centers, aircraft structures, schools, hangers, dormitories, dining facilities, temporary office space, restrooms, guard shacks, border stations, restrooms, mezzanines, and much more.
