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.

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.
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.
The chart details some benefits of pre-engineered modular buildings:
GreenerFasterSmarterThe factory-controlled process generates less waste, creates fewer site disturbances and allows for tighter construction.Construction of modular buildings occurs simultaneously with site work, allowing projects to be completed in half the time of traditional construction.Modular buildings are built with the same materials and to the same building codes and architectural specifications as traditional construction. Once assembled, they are virtually indistinguishable from their site-built counterparts.Less site disturbanceAfter agencies have determined their requirements to include the salient characteristics of the building (see below), they are ready to start the acquisition phase. GSA has a whole host of Pre-fabricated and Pre-engineered buildings available for agencies to purchase through our Multiple Award Schedules Program.
Under Facilities the following Special Item Numbers (SIN) are applicable to pre-engineered and pre-fabricated buildings:
P - Includes storage structures made of wood, fiberglass, steel, aluminum, metal, tension fabric, pre-cast concrete, and more. All options include accessories and may contain recycled or bio-based materials.
Installation solutions can be found under the following ancillary SIN:
- Include installation and site preparation services ordered in conjunction with buildings and structures, building materials, storage tanks/systems, services for alternative energy solutions or power distribution equipment, and fuel dispensing and management systems purchased under this schedule contract.
Below are some examples of salient characteristics that can be used to assist in determining potential requirements for buildings.
The Federal Acquisition Regulation guides the correct use of the MAS program. Ordering procedures vary based on whether or not a Statement of Work is required. Ordering activities must use the procedures in FAR 8.405-1 when ordering Schedule contract supplies (products) and fixed-price services for a specific task, where a SOW is not required (or example: installation, maintenance, and repair).
For Ordering Procedures for Services Requiring a SOW (or example, when ordering Schedule contract services priced at hourly rates), please refer to FAR 8.405-2.

Are any of the prefabs LEED certified?
No buildings are LEED certified at this time
Are sidewalks and utilities required to complete a project covered under any ancillary services SINS or categories?
Sidewalks fall under SIN , installation and site preparation requiring construction. Utility hook up is within the scope of SIN ; the requirement for utility hook up is determined by the customer.
What services (minor construction, ancillary repair) are included in the procurement of the prefab building?
Any services beyond delivery of the building are not covered under the building SIN. Services must be solicited and quoted under the applicable services SIN. The applicable SIN is determined by the extent of services required to provide a turnkey solution.
What types of services are excluded when hooking up a prefab building to the utilities?
Any non-standard electrical requirement within the building.
What is included in the building itself?
Standard and optional items vary by contract, dependent on the standard and optional items offered by the contractor. Non-contract items may can be included in a procurement as open market items. However, open market items are subject to formal price evaluation procedures.
How do you define “Construction”, “Ancillary Repair & Alteration”, and “Minor Construction?”
Complex construction is not approved under GSA MAS contracts.
Facilities Structures includes commercial products that may require services in conjunction with the purchase of the product.
There are three basic types of services available:
Ancillary Repair and Alteration SINs are available in conjunction with purchase of products that require minor construction to be installed properly, such as minor construction necessary to install a door or window, repair drywall, or paint a room. SIN categories are also available to provide installation and site prep requiring construction, services ordered in conjunction with purchase of products to be installed under the Schedule contract—a prefabricated building, solar energy system, roofing, generator, transformer, and more. Davis Bacon and Construction Clauses are incorporated into Facilities Structures contracts offering installation and site preparation requiring construction and R&A. We negotiates fixed rates for services (rates include consideration of prevailing Davis Bacon wage rates). The applicable Davis Bacon wage determination is incorporated at the task order level, when place of performance has been determined.
