PRESOLICITATION NOTICE DISCLAIMER:This document is issued solely for informational and planning purposes as a Presolicitation Notice and does not constitute a Request for Quotation (RFQ), or a promise to issue an award or solicitation in the future.

Specifications, drawings, schedules, wage rate determinations, and solicitation instructions will be provided upon the official posting of the formal RFQ.1. Project Overview & BackgroundThe Canonsburg–Houston Local Protection Project (LPP) is an authorized federal flood damage reduction project spanning over 20,500 linear feet of channel improvements along Chartiers Creek. Originally constructed by USACE in two phases (Houston unit completed in 1970; Canonsburg unit completed in 1976), operation and maintenance responsibilities were subsequently transferred to Washington County.Severe storm events resulted in substantial damage to the channel embankment along the right bank of Chartiers Creek, including displacement of stone protection and loss of subgrade stabilization. This rehabilitation contract encompasses repair and re–armoring of the degraded channel reach to restore federal project integrity and design conveyance capacity.The Anticipated Cost of Construction is between $150,000.00 and $300,000.00.The project is to be completed within 120 Calendar Days after written Notice to Proceed (NTP).2. Technical Scope of Work & Execution LimitsThe contractor must furnish all management, supervision, labor, heavy equipment, materials, water control, and environmental controls necessary to execute the repairs.Repair Reach Limits: Repair work is concentrated along the right bank of Chartiers Creek between approximate stations STA 164+00 and STA 166+50.Site Access & Clearing: Access to the creek channel will be achieved from the left bank access ramp near STA 163+00. The ramp requires clearing of dense brush and vegetation in strict accordance with PennDOT Publication 408, Section 201.Geotextile Underlayment: Existing geotextiles within the damage limits are assumed damaged and must be excavated and replaced. The contractor must furnish and place Class 4, Type A non–woven geotextile fabric conforming to PennDOT 408 Section 735. Panels must be placed over prepared, compacted subgrade with a minimum 18–inch overlap, placing upstream panels over downstream panels.Stone Protection (R–5 Riprap): Riprap protection will be restored using PennDOT R–5 stone (minimum 1`–6“ layer thickness) conforming to PennDOT 408 Section 850 and ASTM D5519. Stones must be placed with zero free fall and a maximum drop height not exceeding 12 inches to prevent fabric puncturing and stone segregation. Hand or mechanical rearrangement is required to achieve a dense, evenly graded mass free of stone clusters or void pockets.Temporary Water Diversion & Dewatering: In–channel work must be performed in completely dewatered conditions. The contractor is responsible for the complete engineering, installation, continuous pumping/diversion, maintenance, and final removal of a temporary water diversion system. All pumped effluent must pass through certified sediment/debris control devices prior to discharge back into the creek. Removed streambed material must be stockpiled and replaced upon completion.Demolition & Waste Disposal: Damaged geotextile, dead vegetative matter, and unserviceable excavated fill must be excavated, loaded, and disposed of off–site at a commercially permitted landfill or recycling facility in accordance with PADEP [ phno? redacted ](Management of Fill).3. Key Personnel & Qualification ThresholdsOn–site supervisory staff must satisfy strict USACE qualifications and maintain designated physical presence:Project Superintendent:Minimum of 5 years of construction experience, including at least 5 years serving as superintendent on comparable earthwork and channel restoration projects.Must possess demonstrated proficiency in USACE EM 385–1–1 safety compliance and hazard mitigation.
