1.0 BACKGROUND

Red Rock Canyon National Conservation Area is located approximately 4 miles west of Sky Vista Blvd in the community of Summerlin. The Red Rock Administration building (Building) is located at latitude:

36.13567 / longitude: - 115.42731 (Exhibit 1).

The Building was originally designed in 1978 and constructed sometime in the early 1980’s and was approximately 1,935 sq. ft. Since that time the building has undergone expansion(s) the last being in 2007/2008. The interior first floor is 7,120 sq. ft. the second floor “mezzanine” is 164 sq. f.t. The exterior floor area under roof is 1,200 sq. ft. Total building square footage is 8,484 sq. ft. (Exhibit 2).

The Building also has 2,470 sq. ft. crawl space. Building occupancy is Group B, construction type is Type V-B (Not Rated).

The Building roof system is composed of two discrete materials; metal B-Decking and sprayed on polyurethane foam (Exhibit 3). Over the years the metal roof system has experienced significant deterioration and is thought to be a major cause of the rodent infestation as well as the water damage at specific interior building locations (Exhibit 4).

BLM closed the Building in February 2023 because of a severe rodent infestation. Rodent impacted areas include crawl spaces, ceiling spaces, rafters, attics, and unused spaces.

This Statement of Work (SOW) details existing Building conditions (Section 6) and what the Government has determined are the minimum tasks needed to successfully complete this project (Section 7).

Red Rock Canyon NCA Administration Building Page 4 of 19

3.0 BUILDING REPAIR CONCEPT

Repair of the Building will be a multi-phase project. Phase 1 will accomplish the tasks outlined in this scope work.

BLM assumes the 2006/2008 Building remodel design was compliant with prevailing building codes at the time.

Except for HVAC equipment, and Batt insulation, BLM does not anticipate upgrading the Building exterior and interior as might typically be done with a tenant improvement. Therefore, a thorough Building inspection to determine what is and what is not in compliance with current codes is not within this scope of work.

4.0 BUILDING DOCUMENTATION

The Government has detailed as-built drawings of the Building that are from the 2006/2007 remodel and Building design drawings from 1978. Due to their large size, these files will be made available at the Contractor’s request using Contractors preferred method of large file electronic exchange.

5.0 SCOPE OF WORK SUMMARY

Listed below are the tasks associated with this project. Section 7 provides details on execution of each task.

1) Rodent Removal and Building Decontamination - Remove from Building, Rodents Feces, and Urine, Impacted Insultation. Deny Building Entry Opportunities to Rodent via Exterior Utility Openings (Section 7.0).

a) Perform initial Building inspection and prepare and obtain Governmental approval of Rodent removal and decontamination work plan (Section 7.1b).

b) Perform Building interior rodent removal and decontamination (Section 7.1c).

c) Perform Building rodent removal and decontamination of areas immediately underlying metal roof (Section 7.1.d).

d) Close Building exterior utility entry points (Section 7.1e).

2) Metal Roof Replacement - Remove all metal roof sections and underlying wood deck and replace with new wood decking and sprayed on polyurethane foam (Section 7.2).

3) HVAC System - Remove and replace existing Mitsubishi heat pumps, wall/ceiling mounted fan control units, and thermostats. Install master controller and connect units to existing Johnson Controls building automation system (Section 7.3).

8) Site and Building Cleanup – Post repair work, ensure all interior and exterior areas are cleaned and free of construction debris. (Section 7.8).

6.0 EXISTING CONDITIONS SUMMARY

Most areas of the building have been inspected for the presence of rodents. That stated, there are several significant areas that have not been inspected. These include the area underlying the metal roof, certain interior ceiling areas, and unused architecturally closed off spaces.

6.1 Rodent Remediation and Building Architecture

One of the key challenges in executing the rodent remediation tasks is the building architecture. The building has multiple zones with varying access challenges. These zones include:

a) Crawl space.

b) Main floor.

c) Ceiling.

d) Mezzanine and attic area.

e) Unused spaces architecturally closed off to reduce Building energy consumption.

f) Rafter areas underlying metal roof.

g) Space between underlying roof deck and existing concrete roof.

Inspections performed by a rodent control contractor indicate that only a few additional relatively small openings need to be constructed to provide full access for the rodent remediation. Existing access openings to the ceiling, unused spaces and crawl spaces are shown on Exhibit 5.

6.2 Existing Metal Roof

BLM personnel typically access the roof via the mezzanine room. The metal roof portion as shown on Exhibit 3 is composed of two main areas and two much smaller areas. Inspections of the roof and other areas show that the roof and wood decking need to be removed and replaced.

Red Rock Canyon NCA Administration Building Page 6 of 19

Past visual inspections show the following:

a) Metal roof areas have loose screws, deteriorated sealant around screws, inadequate/deteriorated flashing, gaps between roof panels, and degraded stucco.

b) Gaps between roof panels are filled with a foam type material that appears to have shrunk and no longer serves its intended function (Photo 1).

c) A hip ridge composed of stucco is deteriorated and separating from the flashing (Photo 2).

d) The condition of the underlying wood deck at loose roof panel edges suggests multiple panels have been water damaged (Photo 3). Photo 4 shows a deteriorated glue laminate beam with large holes.

e) Roof drainage does not work well during heavy rainstorms. At roof edges during heavy rains, water cannot be removed fast enough so it backs up or “dams” on the roof instead of positively draining through down drains and to the ground. It is also likely that down drains are partially blocked. Collectively, this allows water to seep into the roof openings.

f) In the main BLM IT server room, a field engineered 5-foot-long run of roof gutter was installed over the main server rack to divert rainwater that passes through the roofing system (Photo 5).

Note: In late 2022, the Building’s polyurethane foam roof was inspected and found to be in generally good condition although the need for minor repairs was noted.

6.3 Areas Underlying Metal Roof

The condition of the metal roof, flashing, stucco, fascia, gutters, down drains is well known as the roof has been inspected at least three times by roofing contractors, at least twice by rodent remediation contractors, and numerous times by BLM staff. Other than certain wood deck edges, less is known about the overall condition of underlying wood decking as no visual inspections have been performed of areas immediately underlying the roof.

Other BLM inspections suggest that rodents and water have negatively impacted the underlying insulation.

6.4 Exterior Rodent Entry Points

In March 2024, the Government performed an inspection of the Building exterior skin and found numerous utility openings that need to be closed. (Photo 4).

BLM has also noted vegetation within 5 feet of the Building perimeter as well as permanent and temporary material/equipment storage areas adjacent to the building that appear to harbor rodents.

Removing vegetation and materials around the building will be performed by the Government under a separate contract.

6.5 Rodent Infestation

It’s not known how long the rodents have been present in the Building, but it is likely they’ve been present for years. In fact, well over a decade ago, the Building was closed due to the same type of infestation. Past BLM inspections in 2022 and 2023 found rodent feces and urine throughout the

Red Rock Canyon NCA Administration Building Page 7 of 19

Building including above an office, in hallway ceilings, within a large crawl space underlying the main staff workspace, an attic, the IT room floor, and on the floor of an unused closed off space.

Exhibit 6. provides details on where rodents and feces have been observed.

The building has one ceiling access door which is shown in Photo 6 and two crawl space openings, one of which is shown in Photo 7, Exhibit 5 shows the locations.

6.6 Water Damage

Visible water damage is limited to two building areas as shown on Exhibit 4 and Exhibit 7. One location is a restroom that is accessed using an exterior door. Water visibly streams down the south wall into the restroom during and immediately after heavy rainstorms. The top of this wall is below the edge of roof which contains a drainage gutter (Photo 8). The other location is a storage room that is accessed from two separate exterior doors.

6.7 HVAC System

The Building utilizes Mitsubishi City Multi R410A split system heat pumps and fan coli units. Staff have reported that the system has performed reasonably well and been able to provide adequate heat and cooling. Approximately two years ago, BLM evaluated the existing air tonnage and found it adequate to support a staff of 41 persons.

There are four condensers three of which are (4) ton units and one 0.75-ton unit. The 4-ton condensers are 15.5 SEER while the 0.7-ton is 13 SEER. The 0.75-ton unit is dedicated to the main IT room. Two 4-ton units are 16 years old, the third is 8 years old and the 0.75-ton unit is 18 years old.

Exhibit 8 shows the system layout, Photo 9 shows a roof top condenser, there is a second condenser on the roof that is similarly installed.

4 ton condensing units are 230V, single phase units. A 60 amp, 2 pole switch is located next to each unit. Each condensing unit switch home runs to a 240V panel board in the mechanical room. There are

(15) interior fan coil units (FCU). (4) are ceiling mounted and (11) are wall mounted. Individual FCU groups are daisy chained and then homerun to a 240V panelboard. Panel board locations are shown on Exhibit 9. Mechanical schedules and controls are shown on Exhibits 9a and 9b.

The (3) four-ton Mitsubishi condensing units control (1) group of four and (2) groups of five FCU’s.

Refrigerant lines from each condensing unit terminate in a single branch header that is dedicated to the individual condensing unit. Like the condensing units, each branch header serves a grouping of either 4 or 5 FCU’s. Each FCU is served with two refrigerant lines – a high-pressure side and a low-pressure side.

FCU’s are controlled by temperature and time pre-sets within the master control panel. Temperature presets can be locally overridden for several hours but then automatically return to follow the preset programming. Exhibit 9b is an as-built drawing that shows how the FCU’s are manifolded to a single condenser.

Around the 2008/2009-time frame, BLM installed a Schneider Electric (SE) building automation system for both the Administration Building and the Visitor Center. The SE system appears to have utilized the BACnet protocol to send/receive data from energy recovery ventilator field sensors and controller. The

Red Rock Canyon NCA Administration Building Page 8 of 19 exception was the Mitsubishi equipment which utilizes the LonWorks protocol.

In 2015, BLM replaced SE with the Johnson Controls Metasys (Metasys) system to monitor systems in both the Administration Building and the Visitor Center. Metasys monitors the Building energy recovery unit, the potable water distribution system, a solar power generating system, and a solar hot water system. The only system that did not change and directly report to Metasys was the Mitsubishi air conditioning system. Currently that system forwards data to an SE Niagara controller which forwards the data to the Metasys network automation engine (NAE). BLM can “see” temperatures on Metasys but cannot adjust them. To change temperature settings, a laptop computer must be connected to the SE Niagara controller.

The Mitsubishi and SE network controllers are in wall mounted panels in the IT room.

6.8 Existing Operations

Certain Building floor areas contain equipment that provides critical services to multiple on-site facilities including restrooms, the fee station and visitor center. Critical systems include:

a) Potable water storage and distribution pumping.

b) Information technology equipment including phones, computer servers, building automation systems and communication antennas.

c) Hot water system.

d) Fire suppression system.

e) Electrical panel boards and service entry sections.

f) Building energy recovery systems.

Temporary power is provided to two office trailers located in the lower parking area approximately 325 feet south of the Building. The trailers are used as office space for BLM employees and a volunteer non-governmental organization. Power to the trailers is routed from the Building main power panels to a power pole located approximately 20 feet south of the Building and then overhead to the trailers. Trailers and the power poles and line are approximately shown on Exhibit 10 and Photos 10, 11, and 12.

Critical exterior equipment adjacent to the Building include NV energy transformers, a current transformer and meter cabinet and the sites photovoltaic main isolating disconnect Exhibit 11 and Photo 13.

All indicated equipment and systems must remain operational and be protected against damage during Building repair and rodent remediation operations. If any of these systems need to be temporarily shut down so repair work can proceed, provide Government a one week advance notice so adjustments to Government operations can be made.
