About this file

This is an Attachment A document from the Pennsylvania Department of Conservation and Natural Resources (DCNR) Bureau of Administrative Services regarding contractor acknowledgment requirements for Driving Surface Aggregate (DSA) specifications for Solicitation #6100062806. The project involves supplying approximately 4,995 tons of DSA material for the FD10-Sproul Sandy Run Road project, with the tonnage being subject to adjustment based on departmental needs. The document outlines two types of acknowledgment forms: the DSA Contractor Acknowledgment (Form A.1) for contractors creating and supplying DSA directly, and the DSA Quarry Letter of Intent (Form A.2) for cases where DSA will be supplied by a non-contractor-owned quarry.

The technical specifications require the DSA material to meet specific sieve analysis requirements, with particle size distributions ranging from 1½ inch (100%) down to #200 sieve (11-15%, or 11-17% if Plasticity Index ≤2). Additional requirements include pH levels between 6-12.45, LA Abrasion loss <45%, Plasticity Index ≤4, and specific moisture content requirements. The document emphasizes that authorized representatives must sign the appropriate form with their title, be knowledgeable about DSA, and submit only one form (either A.1 or A.2) with their bid response. Failure to comply could result in disqualification.

ATTACHMENT A

Signed Acknowledgement of DCNR DSA Specifications

1. The Contractor must choose the appropriate acknowledgement letter:

a. DSA Contractor Acknowledgement of DSA Specifications (A.1) This form is used when the Contractor will be creating and supplying the DSA.

b. DSA Quarry Letter of Intent (A.2) This form is used when the DSA will be created and supplied by a quarry not owned by the Contractor.

2. The appropriate form must be printed, completed in its entirety, signed, and dated.

a. Both A.1 and A.2 must be signed only by approved representatives of the Contractor and Quarry respectively.

b. The authorized representative must include their title with their signature.

c. Representatives must be knowledgeable of DSA and be prepared to answer all questions on the product.

3. The Contractor must then include the appropriate fully executed form with their bid response (either A.1 or A.2.).

DO NOT attach both acknowledgements.

4. Failure to comply with this requirement could result in a non-responsive determination and subsequent disqualification for the Contractor.

CONTRACTOR ACKNOWLEDGEMENT OF DSA PRODUCT

(FORM MUST BE COMPLETED BY BIDDING CONTRACTOR)

Solicitation # 6100062806 FD10 - Sproul Sandy Run Road Approximate Tonnage – 4,995 tons (Tonnage is estimated and can increase or decrease based on the needs of the Department.)

By signing this acknowledgement I, _______________________________________ (Print Name), an authorized representative of ____________________________________________ (Name of Contractor), confirms that ___________________________________________ (Name of Contractor) has the ability to competently create and supply certified Driving Surface Aggregate (DSA) for the Solicitation listed above that meets the following specifications.

Passive Sieve

Low Percentage

High Percentage

1 ½ inch 100% -- ¾ inch 65% 97%

#4 30% 65% #16 15% 30%

#200* 11% 15%

The fines passing the #200 sieve must be rock material. No clay or silt soil may be added. Limestone material passing the #200 sieve may be used to make up a deficit in the distribution of sandstone aggregate rock, and vice versa. All added material passing the #200 sieve must be derived from rock material that conforms to program specifications. The amount of particles passing the #200 sieve will be determined using the washing procedures specified in PTM No. 100.

*If the Plasticity Index for the Material is 2 or below, then the #200 sieve is permitted to be 11-17%.

pH: 6 – 12.45 as measured by EPA 9045C

LA Abrasion: < 45% loss based on Los Angeles Abrasion test, AASHTO T-96 [ASTM C 131] Plasticity Index: ≤ 4 based on ASTM D4318 – Standard Test Method for Liquid Limit, Plastic Limit, and Plasticity Index of Soils.

Optimum Moisture: Material will be delivered and placed at optimum moisture content, or up to 2% below that value, as determined for that particular source. The optimum percentage moisture will be determined using Proctor Test ASTM D698, procedure C, Standard.
