Slide 20 – Three Project Overview Goals

Project: Mormon Row, Highlands, Taggart Anticipated Construction Year: 2026–2027 Rough Magnitude: Various

Major Content: - Clarified goals of market research and small business participation. - Identified FAR Part 19 socioeconomic categories. - Confirmed competitive FAR Part 15 procurement approach.

Expanded Notes (Context for Contractors):

Molly explained that the remainder of the day would focus on three upcoming projects, but before diving into details, she provided an overview of sources sought notices, market research, and contracting strategy. She noted that three sources sought notices were posted on SAM.gov, all aimed at market research—collecting and analyzing information about industry capabilities to meet agency needs. Responses, including capability statements, are still welcome through the end of the week and will help determine socioeconomic set-asides for each project. The notices seek to identify availability and capability among Small Business, Women-Owned Small Business (WOSB), Economically Disadvantaged WOSB (EDWOSB), HUBZone, Service-Disabled Veteran-Owned Small Business (SDVOSB), Indian Small Business Economic Enterprise (ISBEE), and other categories under FAR Part 19. Molly emphasized that this is not an IFB or RFP and does not commit the government to issue a solicitation; any future solicitations will be posted separately on SAM.gov. She reiterated that all information presented today is preliminary and subject to change. The anticipated solicitation sequence is Mormon Row first, followed by Taggart, then Highlands, with the first RFP ideally posted by the end of January. Each project will likely be procured through open-market Requests for Proposals under FAR Part 15, with one contract per project awarded to a qualified prime contractor. Molly then turned the session back to the Project Management team for detailed project overviews.

Questions / Discussion: - General questions on set‑aside determinations and timing.

Slides 21–29 – Highlands Water and Wastewater Systems Replacement https://youtu.be/CGCuDbzmJO8mJO https://youtu.be/CGCuDbzmJO8mJO

Project: Highlands Water and Wastewater Anticipated Construction Year: Fall 2026 (with winter shutdown) Rough Magnitude: $1M–$5M

Major Content: - Replacement of water distribution and wastewater collection/treatment systems. - Work primarily external to buildings with constrained utility corridors. - Sources Sought issued under NAICS 237110.

Expanded Notes (Context for Contractors):

Project Overview

The Highlands Water and Wastewater Systems Replacement project is a major infrastructure upgrade planned for the Highlands Historic District, located approximately five miles north of Moose. Construction is scheduled for fall 2026 and is expected to last two to three months. The project will replace aging water and wastewater systems to ensure reliable service and compliance with modern standards. Work will occur within a 4-acre project area, disturbing roughly 2.5 acres, with staging planned onsite and possibly at the Beaver Creek boneyard. Standard civil construction equipment will be used, and revegetation will be coordinated with park staff following completion.

Water System Improvements

The water system upgrade includes extending the existing Moose water transmission line to Highlands and installing a new distribution network centrally located among Highlands buildings. This will involve trenching across Cottonwood Creek using diversion and dewatering methods, a process requiring careful environmental management. The existing well and associated infrastructure will be abandoned in place. The new water distribution system, shown in blue on project plans, is designed to avoid Cottonwood Creek to the west and will provide improved reliability and capacity for the district.

Wastewater System Replacement

The wastewater system improvements will include installing two new lift stations, a septic tank, a packaged effluent lift station, and a chambered leach field. Gravity and forcemain piping, shown in green on the plans, will be routed to avoid Cottonwood Creek, minimizing environmental impact. A small lift station will connect unit #1047 to the main gravity system.

The treatment system will consist of concrete septic tanks and a pressure dosing package to ensure efficient wastewater management. The old system will be decommissioned and abandoned in place.

Construction Methods and Challenges

All work will occur outside existing structures within crowded utility corridors, requiring precise planning and coordination.

Plow trenching—a proven technique successfully used in the area—will be employed for installing pipelines, as referenced in both the plans and specifications. This method is highly effective for minimizing surface disturbance and accelerating installation. Seasonal restrictions and environmental considerations will also influence scheduling and logistics.

Coordination constraint: other construction may occur at Moose Entrance Station and Taggart during the Highlands window.

Video Narration Emphasized:

Tight corridors between housing units; existing buried utilities (water/sewer/power/fiber); trees/brush near Cottonwood Creek; pavement repair responsibility if damaged.

Fall window rationale: reduced visitor conflicts + seasonal housing turnover + environmental constraints.

Questions / Discussion:

Will housing units be vacated? Highlands is active housing; seasonal employees typically vacate early fall; some work can occur without directly impacting housing.

2–3 month window seems tight: Government acknowledged narrow windows in GRTE (visitors, weather, wildlife). Noted potential for pre‑work/offline work while occupied (e.g., new septic system, transmission line segments) if access is maintained.

Best value vs low price? CO indicated FAR Part 15 approach and likely best value. –

Remove vs abandon old utilities? Underground piping/tanks largely abandoned in place; above‑ground items (e.g., wellhouse) removed; septic tanks may be filled rather than excavated; site restored to appear undisturbed.

Open items / feedback for solicitation phase: - Encourage offerors to propose phasing/approaches that maintain access and minimize impacts; technical questions handled formally during solicitation.
