For every remodel or new construction project, builders rely on two key documents to deliver the project on time and within budget: the blueprints and the spec book. While the plans visually represent areas requiring architectural elements such as walls, ceilings, or a raised access flooring system, contractors must reference the spec book to determine the manufacturer options, the materials used, specific sizes, and basic installation guidelines.
However, not all specifications are created equal. Depending on the trade, most project spec books utilize a combination of the three types of specifications outlined below.
- Prescriptive specs – describe the project’s materials, finishes, and installation processes to be used. These specs typically reference national standards such as the American Society for Testing and Materials (ASTM) or the International Conference of Building Officials (ICBO).
- Performance specs – typically focus on the finished outcome by establishing minimum performance levels such as functional requirements, environmental conditions, and how the products or system will be tested and confirmed upon installation.
- Proprietary specs – allow the architect to require specific brands, colors, models, and other granular details essential for maximum building performance and durability. This spec option is gaining popularity with property owners, where tenant improvements and future remodeling are expected over the building’s lifespan.
For example, there are nearly a dozen raised access flooring systems available in the marketplace. Property owners and Facility Management (FM) teams that opt for a proprietary raised access flooring spec can ensure future compatibility and compliance over the building’s lifecycle.

The Importance of Construction Specifications
According to ProCore1, construction specifications provide a wide range of benefits for the property owner and the design and build team members.
- Job site efficiency – when a subcontractor has a question regarding their scope of work, they typically must suspend work until they can submit a Request For Information (RFI) transmittal to the owner or architect and await a response. However, when the specs are readily accessible, the subcontractor can quickly clarify the matter and continue working.
- Setting project expectations – specifications are an integral component of the bidding process for subcontractors. The specs outline what will be required if they are awarded the contract for their scope of work, such as certifications, testing requirements, and future maintenance or service needs.
- Improved communications – construction specs ensure that the general contractor, subcontractors, and suppliers involved in the project remain on the same page during construction. Proprietary specs help minimize miscommunications between the parties that can prolong construction schedules and increase costs.
- Quality assurance – comprehensive specs should provide enough details to establish the project’s desired outcome. Providing this information as part of the bidding process can prevent shortcuts or oversights during construction that can impact the quality of the finished build.
- Fewer change orders – using a proprietary spec can reduce construction change orders by clearly defining which product and installation method to use. Prescriptive and performance specs allow the subcontractor to use alternative methods, materials, and manufacturers on the project, which could require change orders for corrective purposes.
- Straightforward procurement and purchasing – subcontractors rely on the project specs to purchase the correct type and quantity of materials needed. Since the specs establish the project requirements or required product lines, they can dramatically impact the project timeline and schedule of values.
Choosing the Right Type of Specification for Your Project
Most prescriptive and performance specs allow bidders to determine which products and vendors they will use for their scope of work. If the architect rejects the proposed products, the project could be delayed while the contractor rebids the affected scope of work.
Typically, proprietary specs are used for remodeling and renovation projects to match existing systems and finishes. However, on new construction projects, proprietary specs can simplify future upgrades while increasing the building’s flexibility and adaptability across its lifespan.
Typically employed by the project’s lead architect or engineer, the project specifier is responsible for assembling the specs. The specifier ensures the specifications are clear and concise to meet contractual obligations and ensure the contractor’s proper execution.
How Proprietary Specs Can Speed Up Your Build
Proprietary specs are ideal for prefabricated components like access flooring systems that can be built off-site and assembled on-site to minimize potential schedule delays. This approach is especially beneficial for home builders, allowing them to streamline construction processes and ensure project timelines are met efficiently.
The Gridd® Adaptive Cabling System uses modular steel components to move the data cabling to a much more accessible location directly above the existing concrete floor. When it’s time for an upgrade or remodel, the contractor removes the carpet tiles (or other modular flooring) to access the affected data cabling. Once the upgrade or remodel is complete, the carpet tiles are reinstalled, and any desks or furnishings are replaced.
Gridd® Power is a power management option that provides unparalleled flexibility through an integrated 50-amp modular bus system designed to work seamlessly with the Gridd Raised Flooring System. The electrical connections can be field-wired to the central panel or made via a modular branch circuit for increased flexibility.
Gridd® Mobile is an Augmented Reality (AR) technology app that allows workers, contractors, and designers to see a virtual cabling map with their smartphone or mobile device. The interface provides easy access to site photos, as-built drawings, and Gridd QR product codes.
