Questions & Answers / Clarifications

This document provides responses to vendor questions regarding Solicitation 140P1426R0002 for the Mormon Row Landscape Rehab project. It clarifies specifications, requirements, and potential ambiguities.

• Asphalt Pavement Abutting Concrete: Sawcutting concrete edges is not required; formed concrete curbs will provide a clean edge. Hot poured asphalt joint sealer is also not required.
• Geotechnical Report: The Geotechnical Report (Soils Report No. 224-145 by Yeh & Associates, dated July 22, 2025) has been attached. Bidders should refer to it for pavement design requirements. If the report's requirements exceed the minimum specified in Section 32 12 16, it may constitute a scope change.
• Dual Hatting Roles: The designated Superintendent can act as the On-site Quality Control Supervisor and On-site Safety Supervisor if they meet the qualifications for each role. Triple hatting (including SSHO and QCM) is also permitted under the same condition.
• Project Tax Exempt Status: Refer to FAR 52.229-3 Federal, State, and Local Taxes.
• Mulching: Mulching is highly recommended but not required. Bidders should adhere strictly to seeding specification section 32 92 19.
• Pervious Pavement: The dark dot pattern on plans indicates pervious pavement (CLIN 3: Trail construction). The lighter dot pattern indicates RAP trail for repair (CLIN 5: Detached Trail).
• Reuse of Demolition Gravel: Suitable demolition gravel from existing parking areas may be reused within the project area.
• Material Disposal: The Kelly Pit cannot be used for disposal of excess or unsuitable material; off-site disposal must be included in bids. Weed-free materials may be stored at the Kelly Pit.
• Selective Clearing: Selective clearing includes work areas within project limits requiring vegetation and soil removal. All staking is the contractor's responsibility.
• Decompaction Depth: A minimum decompaction depth of twelve inches is required prior to replacing salvaged topsoil, as indicated in PART 3.4, E. 1. of specification 32 91 13.
• Construction Phasing: A suggested work sequence is in Section 01 11 00, but alternative sequencing is encouraged. Parking lot work must be completed by November 15; other work by October 1.
• Human Exclusion Fence: The fence will not be removed at the end of construction.
• Empty Conduit: The empty conduit in CLIN 1 is no longer needed. Approximately twenty feet of four-inch diameter PVC conduit, buried 24 inches below the trail, connecting the parking area sidewalk to the Mormon Row accessible trail, should be added.
• Pervious Asphalt Substitution: Pervious asphalt cannot be substituted for pervious trail Filterpave.
• Concrete Edger Manufacturer: No specific manufacturer is required; precast concrete manufacturers meeting the qualifications in 03 40 00 are acceptable.
• Revegetation Experience: Colorado experience is acceptable for Supervisor and Site Crew experience requirements in similar environments.
• Asphalt Mix Typo: The reference to Table 703-4 in the Geotech report is a typo; it should be Table 703-3 for nominal ½ inch grading.

This Q&A document clarifies several technical specifications and logistical requirements. Bidders should review these responses carefully to ensure their proposals accurately reflect the clarified scope and requirements. No changes to submission deadlines or evaluation factors are indicated.
