About this file
This is an Attachment A document from the Pennsylvania Department of Conservation and Natural Resources (DCNR) Bureau of Administrative Services regarding Solicitation #6100062705 for Driving Surface Aggregate (DSA) for East Cowley Run Road in FD13-Elk. The project requires approximately 2,700 tons of DSA (with potential quantity adjustments based on department needs) that must meet specific technical specifications including particle size distribution requirements, pH levels of 6-12.45, LA Abrasion less than 45% loss, and a Plasticity Index of ≤4.
The document outlines two acknowledgment options for contractors: Form A.1 for contractors creating and supplying their own DSA, or Form A.2 for contractors sourcing DSA from a non-owned quarry. Only one form must be submitted with the bid response, signed by an authorized representative with their title included. The representative must be knowledgeable about DSA specifications. Failure to properly complete and submit the appropriate form could result in bid disqualification. The document includes detailed specifications for material composition, testing requirements, and moisture content parameters that must be met by either the contractor or their quarry supplier.

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.

CONTRACTOR ACKNOWLEDGEMENT OF DSA PRODUCT
(FORM MUST BE COMPLETED BY BIDDING CONTRACTOR)
Solicitation # 6100062705 FD13 - Elk East Cowley Run Road Approximate Tonnage – 2700 (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.
