  • Complex repair and alteration of entire facilities or significant portions of facilities.
  • Architectural and engineering services, or AE, under the Brooks-Architect Engineers Act as stated in FAR Part 36.

You can only order ancillary services, incidentals, and equipment rental in conjunction with or in support of products or services purchased under the Multiple Award Schedule contract. This award includes all regulatory at FAR Part 36, including the Davis-Bacon Act and the Miller Act.

The requirements listed in these instructions apply to the following category SINs:

238160 — Includes roofing products, services, and associated application materials. Includes sustainable, energy efficient/savings solutions, and installation and site preparation, related to and ordered in conjunction with products for repair or replacement of an existing roof.

Stand-alone services including repair and maintenance services are subject to Service Contract Labor Standards wage rates. You must follow solicitation provision SCP-FSS-001 requirements for professional services. 


Required supplemental documentation you must submit with your offer

According to FAR 8.404(d), supplies offered on MAS are listed at fixed prices. Services offered on SIN 238160 or 238910 are priced either at hourly rates, at a fixed price for performance of a specific task, or a combination of the two, such as installation of a product.

Using estimating and pricing software

  • If you intend to use the construction estimating software RSMeans to price services, please skip to the RSMeans section.
  • If you intend to use computerized pricing software for products being offered under the potential contract, please review the solicitation and SIN 332311P notes for building sample pricing requirements.

You must submit the following information if you are offering services under SIN 238160 or 238910. These documents should be uploaded as part of your offer submission. Failure to submit the requested supplemental documentation may result in rejection of your offer.

  • A description of services to be performed.
  • Labor category qualifications (if pricing offered is by labor categories).
  • Detailed project summaries.
  • Commercial services price list — services offered need to be listed on your commercial price list or a separate price list for services.
  1. Description of services

    Pricing submitted should be in accordance with commercial practices such as labor rates or fixed unit prices. If pricing is based on labor rates, you must supply and clearly define each labor category provided in this section. All services offered should relate to the products being offered, and you must define the scope of services to be offered as they relate to the installation of the product. If pricing is based on fixed unit prices, provide a detailed breakdown of what functions to be provided are within the fixed unit price. Provide these descriptions of services in a document titled Description of services to be uploaded as a supplemental document with your offer submission or subsequent modification. Sample descriptions are provided below:

    Example A

    Electrician — Removes existing light fixtures, installs new light fixtures.

    Example B

    Installation of floor tile — Installation is priced per square foot and does not include cost of tile. Installation includes removal of current floor covering, preparing surface, laying of tile, grouting, and cleaning excess grout from tile. All materials and labor required for the installation as stated is included in the price except for the tile.

    Installation of above ground storage tank — Installation does not include cost of tank. Installation includes standard 10’x10’ concrete pad and affixing the above-ground storage tank to the pad. All labor and industry standard materials meeting local codes are included.

  2. Labor category qualifications

    If offering services pricing by labor category, you will need to provide the following for each category — required experience, minimum training, level of education, and certifications or licenses, if applicable. Provide these descriptions of services in a document titled Labor category qualifications and upload it with offer submission or subsequent modification. Examples are:

    Electrician I - Two-year technical degree. Minimum of two years experience. Trained in commercial building electrical systems. Licensed and bonded.

    Electrician II - Two-year technical degree. Minimum of five years experience. Trained in commercial building electrical systems. Licensed and bonded.

  3. Detailed project summaries

    You must provide a written summary (including detailed cost information) of at least three projects completed within the previous 12 months that are similar in nature to the services being offered under the solicitation. If you do not submit invoices as supporting documentation for cost information, then you must provide a cost breakdown of services provided within the project. We must be able to clearly see pricing offered for services commercially. Your narrative for each project is limited to three pages. Do not provide statements of work in lieu of the written narrative. Provide these project summaries in documents titled Project summary 1, Project summary 2, and so on with all supporting documentation for each project and upload it in one document with your offer submission.

    Note — The requirements of SCP-FSS-001 differ from Services Pricing Proposal documentation requirements. If you are offering services under these SINs and do not provide the supplemental documentation as required in this guidance, we will reject your offer.

  4. Services pricing

    We prefer established commercial pricing in a published and dated catalog or price list. If you do not include services pricing in your commercial price list, provide a separate commercial services price list that has an effective date. Based your established commercial pricing on Format One (fixed unit price) or Format Two (labor rates) and mirror commercial pricing.

    Incidental products: These items that are necessary to complete a project must be priced on the contract or offered as open market items. We encourage you to identify and price all incidental products in the services pricing proposal. When the cumulative value of incidental items on a task or delivery order exceeds the micro purchase threshold, the items must be procured in accordance with applicable acquisition regulations. The cumulative dollar value of the incidental items is key to determining the publications and competition requirements for federal customers. For some industries under SIN 238160 or 238910, incidental items necessary to install a product may easily exceed the micro purchase threshold; therefore, it is in your best interest to include pricing for incidental items in your pricing proposal.

    Awarded incidental products must be directly related to performance of the services provided. A contractor may quote reduced pricing for incidental products based on the specific task identified at the task order lever. However, a contractor may never exceed the awarded price for any product or service without a modification to the contract.

    Please be aware that ordering agencies placing task orders under a MAS contract may not be charged for any items and/or services that have not been approved and awarded under a vendor’s contract. Contracts can be modified to add or delete items as appropriate.

    Industrial Funding Fee, or IFF: Offerors are required to identify the prevailing IFF as a separate calculation in the prices submitted with the offer. The fee is not included in the net contract price, but is reflected in the total amount charged to ordering activities. The IFF must be calculated as a separate collection mechanism, i.e., Base Rate – GSA Discount = Net Rate + IFF = total proposed hourly rate. There will be no exceptions; IFF is a separate collection mechanism and must be shown clearly as an adder to the net hourly rate.

Maintenance and repair certifications

Please list the brands that you are authorized to perform repairs/maintenance on. We ask that you provide proof in the form of letters from manufacturers, service agreements, certificates of authorization to perform repair work, etc., that clearly state that you the contract holder/offeror are certified/authorized to perform service on the brands listed. Please ensure the certificates show effective dates. It is your responsibility to ensure these certifications are kept current. If certification lapses or is not renewed, you will have to submit a modification request to remove these services for your contract.


If you are offering services utilizing RS Means

Services should be offered under SIN 238910. Services can only support products offered under SIN 332311P.

If you are proposing to offer services under SIN 238910 utilizing RS Means, you will need to provide the following documentation with your eOffer submission/modification request:

  1. TAA Compliance Assurance Letter — Located in the TAA compliance section, this requirement must be completed by the contract holder (or potential new contractor), provided on company letterhead with the eOffer submission, and uploaded as an ‘Optional’ document in the eOffer system. This should be signed and dated by an authorized negotiator listed on the contract or a company officer. If submitting a new offer, upload into your eOffer under the ‘Optional’ document tab or include as an additional document with your mod submission. Please label the document “TAA Compliance Assurance Letter.”
  2. Please define the scope of services to be performed under the contract. In a separate document, please provide a narrative of the anticipated services to be performed utilizing RS Means relative to the scope of the product being offered. If submitting a new offer, upload into your eOffer under the ‘Optional’ document tab or include as an additional document with your mod submission. Please label the document “RS Means scope of services.”

Note — The Contract Specialist assigned to your offer will request current RS Means version information in the clarification stage of your submission. If submitting a modification, please notate the current version you are submitting under in your cover letter. Contractors will utilize RS Means to price ancillary services under SIN 238910 to include labor services, product incidentals, and equipment rental related to the specific approved price list of products on contract. Utilization of RS Means is limited to the ancillary installation and servicing of the specific products purchased under the MAS contract and approved installation SINs. Contractors approved for services under RS Means will utilize only material and labor unit prices within RS Means. The current RS Means version will be approved and quarterly automatic updates issued by RS Means will be utilized by the contractor when released. The most current version of RS Means is to be utilized by contractor as long as RS Means is approved to price ancillary installation under contract. A contractor may never exceed the RS Means unit price for any product or service without a modification to the contract.
