1.2 WORK COVERED BY CONTRACT DOCUMENTS

A. Project Location: Big Bend National Park, Chisos Basin and Oaks Springs, Texas.

B. The Work of this project consists of replacing the existing Chisos Mountains Lodge with a new facility and rehabilitating the Chisos Basin Water System. This is a single project organized into two components as described below:

1. Lodge Component: The Lodge component of this project will demolish and replace the Chisos Mountains Lodge and provide adjacent site improvements.

a. Bid options under the Lodge Component include kitchen equipment, a new accessible route between the main parking lot and Lodge, additional site improvements, expansion of the Chisos Mountains Visitor Contact Station building, demolition of the Camper Store, restoration of the Camper Store site, a rainwater harvesting system, a battery and microgrid system, and photovoltaic panels at the Lodge.

b. The Lodge Component is designed to comply with a Silver Certification Level according to the United States Green Building Council's (USGBC) Leadership in Energy & Environmental Design (LEED™) Rating System, as specified in Section 01 81 13 "Sustainable Design Requirements – Lodge Component."

2. Water Component: This item consists of all demolition, repair, and replacement work on the Chisos Basin water system including storage tanks, treatment facilities, distribution system, and SCADA systems associated with the Chisos Basin public water system (PWS).

BIBE 259631-317515 01 11 00 - 2

112723 SUMMARY OF WORK

The Water Component includes new pumps at Oak Springs and associate required building improvements, and a new ultrafiltration building and system at Chisos Basin.

C. Project will be constructed under a single prime contract.

D. Construction operations and sequencing shall be organized between the two components to most efficiently and cost effectively accomplish the project. Rework in areas where the components overlap is to be avoided.

1.3 RELATED SECTIONS

A. Section 01 28 00 – Contract Requirements for Park Operations and Resource Protection

1.4 WORK PHASING AND SEQUENCING

A. The Lodge and Water Components are to be constructed concurrently. The Lodge component shall be constructed in a single phase. The Water component requires specific sequencing to maintain the water system’s operation throughout construction as described below.

B. Phasing and Sequencing of Work in Archeologically Sensitive Areas: For both the Lodge and Water components of the project, the Contractor shall schedule and sequence the work so as to avoid activities which involve ground disturbing work in archeologically sensitive areas from being or becoming critical path, to the greatest extent possible.

C. Water Distribution System Sequencing:

1. Phase 1 – Campground Distribution

a. Shut down Basin campgrounds service.

b. Provide temporary water service via trailer mounted pressure washer stationed at the existing Wastewater Treatment Plant (WWTP) to be used for cleaning purposes until water service is re-established.

c. Construct new water main and related services and appurtenances in kind at the campgrounds. Once complete, test, chlorinate and activate the new lines.

d. Return service to WWTP. Remove/return temporary pressure washer.

e. Simultaneously construct the offset parallel water main in non-sensitive archaeological areas (to be tied in later). Those locations include the areas between the Visitor Contact Station parking area and the lower campgrounds. Parallel alignments in that area include the residences and public restroom (group campgrounds), as well as the ‘cross country’ areas between those locations.

f. Install new water service meters at existing meter locations.

g. Tie-in to existing system near the parking lot of the Visitor Contact Station.

h. Once complete, test, chlorinate and activate new lines.

2. Phase 2: Remaining Site Distribution

a. Install above ground temporary water main and services at the lodge parking lot area and tie-in to the newly installed offset parallel mains from Phase 1.

BIBE 259631-317515 01 11 00 - 3

112723 SUMMARY OF WORK

b. Perform tie-in work at the residences area to connect the offset main coming from the lodging area to the new downstream distribution system.

c. Utilize the existing water distribution infrastructure ‘upstream’ from the Lodge area to connect to a temporary water line at the lodge area and the new system downstream of the lodge area, while the lodge area pipe is replaced in place.

1) A new fire hydrant south of the lodging area parking lot may need to be installed for fire suppression

d. Construct a new replace in place water main and related services and appurtenances in kind at the lodge area.

e. Install new water service meters for lodge area at existing meter locations.

f. Perform tie-ins to offset mains from Phase I.

g. Once complete, test, chlorinate and activate the new distribution system.

C. Chisos Basin Treatment and Tank Site Sequencing: The removal and replacement of water storage at the Chisos Basin t reatment and tank site, shall be conducted in three (3) phases, with each phase substantially complete as indicated. Refer also to sheets C1.05, C1.06, and C1.07 of the Water Component set.

1. Phase 1:

a. Demolish the existing 125,000-gal concrete storage tank.

b. Construct the yard piping to connect the effluent piping from disinfection to the influent piping of the cartridge filters and the effluent piping from the cartridge filters to the existing yard piping to the existing 500,000-gallon tank.

c. Install 10,000 gallon temporary break tank to be used for raw water storage from the Oak Springs Pump Station. Connect the temporary break tank to the fill line feeding the Chisos Basin site. This tank will require daily pumping at Oak Springs for approximately 4-6 hours. The temporary break tank will be installed with a liquid level indicator and overflow piping with associated valves and appurtenances.

d. Control of the existing cartridge filter transfer pumps in the Filter Building will be changed to be controlled by the liquid level indicator in the 10,000-gal break tank, turning off at the low-level elevation.

e. Filtered water will be stored in the existing 500,000-gal storage tank to maintain service to the distribution system while the new tank is being constructed.

2. Phase 2:

a. Continue using 10,000 gallon break tank for temporary raw water storage. Pumping controls will be similar to Phase 1 controls. The existing 500,000-gallon water storage tank will continue to be used as the finished water storage tank during Phase 2 construction.

b. Construct the remaining yard piping at the Chisos Basin tank site.

c. Construct a new 500,000-gal glass-lined, glass-infused steel storage tank.

d. Begin construction of the ultrafiltration (UF) building and equipment.

3. Phase 3:

a. Upon substantial completion of the new 500,000-gallon water storage tank and yard piping, the new 500,000-gallon water storage tank shall be brought online for use.

BIBE 259631-317515 01 11 00 - 4

052125 SUMMARY OF WORK

b. Filtered water will be stored in the new 500,000-gal storage tank to maintain service to the distribution system while the existing 500,000-gallon tank is being rehabilitated.

c. Clean and rehabilitate the existing 500,000-gal steel storage tank.

d. Startup and testing of full water system.

e. Remove 10,000 gallon break tank.

D. Substantial Completion of Intermediate Phases: Perform Final Inspections, Substantial Com-pletion, and Acceptance Procedures per Section 01 77 00 Closeout Procedures at completion of each of the following intermediate phases for the Water Component:

1. Oak Springs Building Improvements and Treatment System

2. New Tank Installation and Yard Piping at Chisos Basin

3. Ultrafiltration (UF) Building, UF Treatment System, and Rehabilitation of Existing Tank at Chisos Basin

4. Campground Water System Distribution

5. Residential Area Water System Distribution

6. Lodge Area Water System Distribution
