2.1.9.2. Codes, References and Guidelines:

The building and new addition are to conform to the APPLICABLE CRITERIA provided in this

SOW. See the Appendices.

2.1.10. THERMAL PERFORMANCE

2.1.10.1. BUILDING ENVELOPE SEALING PERFORMANCE REQUIREMENTS

Design and construct the Administrative and Visitor Center Building envelopewith a continuous air barrier to control air leakage into or out of the conditioned space. Identify all air barrier components of each envelope assembly on construction documents and detail the joints, interconnections, and penetrations of the air barrier components. Identify the boundary limits of the building air barriers and of the zone or zones to be tested for building air tightness on the drawings.

Trace a continuous plane of airtightness throughout the building envelope, make flexible, and seal all moving joints.

The air barrier material(s) must have an air permeance not to exceed 0.004 cfm / sf at 0.3” wg when tested in accordance with ASTM E 2178.

Join and seal the air barrier material of each assembly flexibly to the air barrier material of adjacent assemblies, allowing for the relative movement of these assemblies and components.

Support the air barrier to withstand the maximum positive and negative air pressure to be placed on the building without displacement or damage and transfer the load to the structure.

Seal all penetrations of the air barrier. If any unavoidable penetrations of the air barrier by electrical boxes, plumbing fixture boxes, and other assemblies occur, make them airtight by sealing the assembly and the interface between the assembly and the air barrier or by extending the air barrier over the assembly.

The air barrier must be durable to last the expected service life of the assembly.

Do not install lighting fixtures with ventilation holes through the air barrier.

Provide a motorized damper in the closed position. Connect the damper to the fire alarm system to open on call and fail in the open position for any fixed open louvers.

Damper and control to close all ventilation or make-up air intakes and exhausts, etc., when leakage can occur during inactive periods.

2.1.10.2. PERFORMANCE CRITERIA AND SUBSTANTIATION

Submit the qualifications and experience of the testing entity for approval. Demonstrate performance of the continuous air barrier for the opaque building envelope by performing the following tests:

01 10 00.00 20 – Statement of Work – Project Specific Requirements - Page 8

Test the completed building and demonstrate that the air leakage rate of the building envelope does not exceed 0.4 cfm/ft2 at a pressure differential of 0.3” wg in accordance with ASTM’s E 779

(2003) or E-1827-96 (2002). Accomplish the tests by using pressurization or depressurization or both. Divide the volume of air leakage in cfm at 0.3” wg by the area of the pressure boundary of the building, including roof or ceiling, walls, and floor to produce the air leakage rate in cfm/ft2 at

0.3” wg. Do not test the building until it was verified that the continuous air barrier is in place and installed without failures in accordance with installation instructions. This will allow for timely repairs to the continuous air barrier, if needed, to comply with the required air leakage rate. Test the completed building using Infrared Thermography. Use infrared cameras with a resolution of

32.18 deg. F (0.1deg C) or better. Perform testing on the building envelope in accordance with the ISO 6781:1983 and ASTM C1060-90(1997). Determine air leakage pathways using ASTM E

1186-03 Standard Practices for Air Leakage Site Detection in Building Envelopes and Air Barrier

Systems, and perform corrective work, as necessary, to achieve the whole building air leakage rate specified above.

Notify the Government at least three (3) working days before the tests are performed to allow the

Government the opportunity to witness the tests. Provide the Government written test results confirming the results of all tests.

2.2. EXISTING CONDITIONS

Use the provided information to develop the proposal and design the site. If a conflict exists between any of the reference drawings and documents provided by the Government and the technical requirements of the RFP, the RFP technical requirements will govern.

2.2.1. EXISTING ADMINISTRATION AND VISITOR CENTER BUILDING

The existing Administration and Visitor Center Building is comprised of the original

Administration Building constructed between 1958-1960 and a Visitor Center addition constructed on the east side of the building in 1992, essentially creating two wings,the Visitor

Center wing in the west section of the building and the Administration wing in the east section of the building. The Visitor Center wing is comprised of an Exhibit Area, Theater, Kitchen, Main

Entrance, Public Restrooms, and other storage and support spaces while the Administrations wing is comprised of Offices, Conference Room, Employee Breakroom, and Employee

Lockers/Shower space, Employee Restroom, and other storage and support spaces.

The original Administration Building is constructed of loadbearing masonry walls with a flat roof comprised of steel bar joists and a steel deck while the addition is constructed of wood frame with brick veneer walls and a flat roof of wood joists and plywood roof. Due to the original building being part garage, the floor elevation of the Exhibit Area, Public Restrooms, and some other support spaces in the Visitor Center wing is higher than the floor elevation of the Theater, Kitchen, Main Entrance, and Administration addition. Throughout the years, various interior modifications and HVAC and electrical upgrades have been done to meet the needs of the

01 10 00.00 20 – Statement of Work – Project Specific Requirements - Page 9 occupants and mission. The original construction, addition, and most modifications are provided as reference drawings in the Appendices.

Due to issues with leaking of the flat roofs, a steel truss hip roof structure with insulation and a standing seam metal roofing was installed over the entire building between 2021-2022.

Unfortunately, during construction, rainwater inundated much of the interior during a sudden storm and damaged many of the finishes and caused mold growth within the walls and under the floor finishes. Because of this damage, almost all finishes (including those with asbestos containing material) have been removed along with all drywall and insulation from the walls, leaving only the wood stud or masonry interior walls, some ceiling grid, lights, electrical and

HVAC systems. The current conditions can be seen in the photos in the Appendices.

2.2.2. EXISTING RANGER STORAGE BUILDING

2.10 STRUCTURAL REQUIREMENTS

2.10.1. GENERAL

Analyze, evaluate, design, and detail the building(s) as a complete structural system. Design structural elements to prevent damages to finishes, partitions, and other frangible, nonstructural elements; to prevent impaired operability of movable components; and to prevent cladding

01 10 00.00 20 – Statement of Work – Project Specific Requirements - Page 16 leakage and roof ponding. Limit deflections of structural members to the allowable of the applicable material standard (e.g., ACI, AISC, AISI, AWC, etc.) The design of the building’s structural components is to be completed by a registered professional engineer licensed in the

State of Iowa, with experience in the design of similar structures.

Account for interior and exterior climate conditions, extreme weather mitigation/resiliency, exposure and occupancy/risk categories, site considerations, and other adverse conditions when selecting cement and admixture types to be used in concrete, the concrete cover over reinforcing steel, the coatings on structural members, expansion joints, the level of corrosion protection, and the structural systems. All concrete will be a minimum of 4,500 psi and be reinforced. The floor-mounted mechanical and electrical equipment will be placed on a concrete slab by the Contractor.

In addition to gravity/uplift/lateral loads and seismic loads (if applicable), design ancillary building items (i.e., doors, window jambs and connections, overhead architectural features, equipment bracing, etc.) per the current minimum requirements of DoD Minimum Antiterrorism Standards for

Buildings: Unified Facility Criteria UFC 4-010-01.

2.10.2. APPLICABLE STANDARDS, CODES, AND CRITERIA

The structural design will fully follow the provisions provided in the APPLICABLE CRITERIA. See the Appendices. Use the latest edition of the International Building Code (IBC) and American

Society of Civil Engineers (ASCE) 7 for design guidance and coordinate the design with the current UFC 4-010-01. Where the provided guidance in one standard conflicts with the guidance provided in another, the more stringent design provisions will prevail.

2.10.2.1. Project Specific Minimum Design Loads (per UFC 3-301-01):

1) Dead Loads:

• Roof-Mounted Solar Panel Allowance (new construction only)

2) Live Loads:

• 20-psf (roofs – all other construction)

• 50-psf (office buildings – offices)

• 80-psf (office buildings – corridors above first floor)

• 100-psf (office buildings – lobbies and first floor corridors)

• 125-psf (storage warehouses – light; mechanical and electrical rooms*)

• 250-psf (sidewalks, vehicular driveways, and yards subject to trucking)

3) Wind Loads (New Construction Only):

• 120-mph (3-second gust, risk category II, exposure category C)

4) Snow Loads:

• Design for balanced and unbalanced loads

• Frost Penetration Depth: 42-inches

5) Seismic Design Data (New Construction Only):

• S1 (MCER ground motion, 1.0s period) = 6%g

01 10 00.00 20 – Statement of Work – Project Specific Requirements - Page 17

The acceleration values identified are for the general location of the facility. Verify and use site specific criteria based on the final site location of the facility. Adjust site class per IBC to match specific site information in the geotechnical report.

2.10.2. FOUNDATION:

New foundations must be site-specific and be designed with known geotechnical considerations by an engineer knowledgeable of the local conditions (e.g., expansive soils, groundwater levels, etc.). New interior bearing walls and/or columns are to have new foundations cut into the lower-level floor slab as required for adequate support. Coordinate the need for a vapor barrier with the architectural floor finishes and requirements of the Geotechnical Design Report.

All slabs-on-grade will receive a coating (i.e., epoxy) or an overlaying finish (i.e., carpet, tile, etc.), and be underlain by a vapor barrier system with a minimum of 10-mil polyethylene membrane.

All building slabs and foundations at the project location must be treated for subterranean termites per Unified Facilities Guide Specification (UFGS): UFGS 31 31 16 – Soil Treatment for

Subterranean Termite Control, prior to concrete placement.

2.10.3. Floor Framing:

Floors of new construction must be ordinary slabs-on-grade.

2.10.4. Concrete Masonry Unit (CMU) Masonry Walls:

When applicable, new CMU walls, either load bearing or non-load bearing, may be used, provided exterior walls satisfy UFC 4-010-01. See Section 2.14.3.6.

Interior Framed Partition Walls:

Interior framed partition walls should be designed in a manner that minimizes sound transmission and improves acoustical performance.

2.10.5. Roof Framing:

Provide permanent fall protection anchor points on the roof for future building maintenance and other work. The fall protection system should be able to carry a single 5,000-pound. impact load for each person attached to the system.

2.10.6. Design Analysis:

Computer- generated calculations must identify the program’s name, source, and version. Provide input data and include loads, loading diagrams, node diagrams, and adequate documentation to illustrate the design. The schematic models used for input must show, as a minimum, nodes/joints, elements/members, materials/properties, and all loadings, reductions, factors of safety, induced settlements/deflections, etc., and a list of load combinations. The results must include an output listing for maximum/minimum stresses/forces, deflections/deformations for each element, and reactions for each loading case and combination.

2.10.7. Project Specific Design Analysis Requirements:

Provide updated structural computations for the existing Administration Building’s wood floor framing load capacity. Account for any proposed changes to floor loads (i.e., floor finishes, occupancy/use, etc.) to confirm its performance and verify that it is structurally adequate.

Storage Addition with a covered connecting walkway. As a potential betterment, the covered connecting walkway would be enclosed and heated/cooled.

2.11.2. FUNCTIONAL AND AREA REQUIREMENTS

Refer to Room Data Sheets (See APPENDIX 6 ROOM DATA SHEETS) and Adjacency Matrix

(See APPENDIX 9 – ADJACENY MATRICE) in the Appendices for a list of required spaces, areas, and adjacencies.

2.11.2.1. Definitions:

Gross Building Area Total constructed area of the building. It is measured to the outside finished surface of permanent outer building walls, without any deductions. Non-enclosed roof areas are counted at 0.5.

Net Area Net area is measured to the inside face of the room or finish walls.

Net Area Requirements

Net area requirements for programmed spaces are included in this SOW.

If net area requirements are not specified, the space is to be sized to accommodate the required function and to comply with code requirements, overall gross area limitations, and any other requirement of this RFP (for example, area requirements for corridors, stairs, and mechanical rooms will typically be left to the discretion of the Contractor).

2.11.2.2. ADMINISTRATION WING FUNCTIONAL REQUIREMENTS

The Administration wing of the existing Administration and Visitor Center Building will provide administrative space for USACE personnel to carry out their daily activities to achieve various missions.

Natural Resource Specialists (Park Rangers) perform various duties at the reservoir both in the field and administrative functions. Rangers are responsible for program areas of flood risk management and dam safety, recreation management, and environmental stewardship. These duties are often done in teams, so they will require their offices near one another to collaborate, hold meetings and perform their daily functions.

All management staff perform administrative functions of managing the project’s lands and water, budget, and personnel. These offices should be away from the Natural Resource Specialists for privacy in daily administrative duties. Administrative staff assists all employees with many administrative responsibilities, purchases, travel, and timekeeping functions. All employee offices and common areas should be away from public view and access.

The main building access for employees will be on the northeast end of the Administration and

Visitor Center Building. The access will be secure and separate from the public. The administrative areas intended for daily USACE operational activities must be secured from the general public’s access and view. The public will only have open access to the main lobby and the Visitor Center.
