1. OWNER AND USER REQUIREMENTS

a. Primary Purpose, Program, and Use

Project P-1035 will provide a three-bay hangar facility in support of depot level

Planned Maintenance Interval requirements for the MH-60R/MH-60S and V-22 aircraft. This single-story building will consist of 53,585 total gross square feet. The high bays consist of a Plastic Media Blasting (PMB) Bay, a Paint Bay, and a Wash Rack

Bay. While the Paint Bay and the Wash Rack Bay will serve both series of aircraft; the

PMB Bay will only serve the MH-60 aircraft series. Each bay is supported by several ancillary spaces, either directly accessible or adjacent to the bay itself.

b. Project History

The existing V-146 facility is a 2004 converted warehouse that is being utilized by

Fleet Readiness Center Mid-Atlantic (FRCMA) for washing, plastic media blasting

(PMB) and painting of MH-60RS (Seahawk helicopter) air frames. The 1970 building, located on the seawall at Naval Station Norfolk, is inadequate and sub-standard for the current facility functions and will not support the proposed up-graded maintenance functions for these air frames.

c. Broad Goals

• Provide a facility utilized by Fleet Readiness Center Mid-Atlantic (FRCMA) for washing, plastic media blasting (PMB) and painting of MH-60RS (Seahawk helicopter) and CMV-22B (Osprey) air frames.

• Future Expansion: Not Anticipated

• Quality of Materials: Materials chosen for durability and are intended for a minimum of 50-year life span

• Anticipated Operational Costs: Unknown

• The design must be fit for construction.

• The design and construction must be commissionable.

• The commissioned equipment and systems must be reliable, operational and maintainable.

• Provide a new, non-leaking facility above the 100-year flood plain, sized for current and proposed operations with adjacency to Building V-147 that provides the basic facility requirements for the spaces as outlined herein.

• Project site has contaminated soil (heavy metals from plating process): Per the

Environmental Office, vapor intrusion mitigation with a passive venting system with testing portals/active emergency exhaust is not required. Provide for containerized dewatering and disposal of contaminated soils during construction

• Incorporate cathodic protection for underground utilities in the design.

• Environmental Air Permits are required (to be updated by MIDLANT).

• Address Antiterrorism (AT) with new design: Note that most of the facility (high bays) is considered “low occupancy” and is not subject to the current antiterrorism requirements.

• Incorporate fall protection and work platforms into new design.

• Provide an underfloor PMB recovery system and protection from weather for disposal of the drums below the dust collectors.

• Attempt to “celebrate” the stacks, HVAC equipment in the building exterior design

• Provide a comprehensive Acoustical Study (both exterior and interior noise) for the facility and include testing as part of the construction package.

• Incorporate Cybersecurity requirements into the design, including HVAC/DDC controls, electrical power and lighting controls, fire alarm/mass notification system, AMI metering and specialty systems.

• GBI “Guiding Principles” compliance with Third Party Certification.

• Provide for Third Party Commissioning of building/systems in accordance with

UFC 1-200-02 and Guiding Principles.

• Provide design/bid/build documents for competitive bidding by 01 September

2020 within budget and/or with bid options identified.

• Provide a System Manual for the owner’s use at completion of commissioning

• Estimated construction completion date 30 April 2023.

d. Budget Considerations and Limitations

Total authorized funding for the FY21 project is $60,200,000, with an estimated construction cost (ECC) of $53,387,447. The project “design to” goal is 90% of the

ECC ($48,048, 702) with bid options identified with the final design package.

Mod P00002 to the A/E contract (not executed as of the date of this document) indicates reduced funding: Program Amount, total authorized funding reduced to

$60,000,000. Estimated construction cost (ECC) is thereby reduced to $53,209,893;

and the project “design to” goal is 90% of the ECC ($47,888,903), with bid options identified with the final design package.

e. Design Assumptions

i. Facility designed for 3-step process of primer (base coat) + intermediate

(“sticky”) coat + final coating. Intent is for final coat to be removed, the intermediate coat to be patched and the final coat to be replaced. This is a new process and no examples are available for review/design guidance.

This design is based on this logic.

ii. Facility design is based on similar Corrosion Control Hangar at New River, NC; however, that facility only has wash rack and PMB functions and no painting application.

iii. Building life expectancy is 50 years.

3. ENVIRONMENTAL AND SUSTAINABILITY GOALS

a. Guiding Principles Goals

The goal for this project is to achieve Guiding Principles Compliance, in accordance with the Green Building Initiative’s Guiding Principles Certification. The owner expects to incorporate a sustainable design that reduces the impact on the environment, reduces energy consumption, and creates savings over the life of the project.

b. Other

This project should be designed with the intent of maximizing the use of sustainable design and development practices. Sustainable principles should be integrated into the design, development, and construction of the project in accordance with all federal mandates (such as but not limited to UFC 1-200-02 High Performance and

Sustainable Building Requirements, EPAct’05, EISA 2007, HPSB Guidelines 08, Executive Orders (E0 13514)). Solutions which conserve energy, improve livability, and can be justified by Life Cycle Cost Analysis (LCCA) as cost effective are to be utilized. All system selections are to be made and justified through a LCCA process.

4. ENERGY EFFICIENCY GOALS

a. Goals/Policy

Energy targets for the project are set by UFC 1-200-02 High Performance and

Sustainable Buildings Requirements and Guiding Principles.

UFC 1-200-02 requires compliance with ASHRAE 90.1-2013. Overall building energy consumption 30% or more below an ASHRAE 90.1-2013 baseline building is required where life cycle cost effective. UFC 1-200-02 also states that “If none of the reduction choices is life-cycle cost-effective, modify the design of the proposed building system(s) to achieve an energy consumption level at the highest level of energy efficiency that is life-cycle cost-effective.”

Based on the energy model, the current projection is 5.02% energy reduction over the baseline system. This is due to the high process load that the ventilation and exhaust requirements of these spaces, and the explosion-proof requirements of the equipment.

b. Systems and Feature Energy Impact

• Building envelope systems meet or exceed ASHRAE 90.1-2013 minimum energy performance requirements

• Interior and exterior lighting systems use high performance LED lamps.

• The mechanical system was selected based on detailed life cycle cost comparison with a 40-year study period.

6. EQUIPMENT AND SYSTEM EXPECTATIONS

a. Critical Systems

The following are identified as “critical” systems and require review and approval by the NAVFAC Acceptance Group as part of the commissioning process per their definition of “acceptance”. These systems are described herein (along with their design criteria) and are:

1. HVAC (including DALT, TAB, PVT testing and interface of controls with the cybersecurity requirements)

2. Electrical (including generator sets, automatic transfer switches, cathodic protection and transformers)

3. Fire Protection/Life Safety Systems

4. Roofing and roof drainage systems

b. Civil Systems

There are no systems associated with the grading, paving and utility sitework for this project. The only permanently installed equipment is a manufactured filtering device in an off-line configuration on the storm drainage system serving the apron pavement. The device must be inspected and cleaned as necessary based on the manufacturer’s recommended inspection and maintenance guidelines. Maintenance will include removing accumulated sediment and debris, rinsing and/or replacement of filter cartridges.

c. Cathodic Protection Systems

There are a number of underground utilities associated with this project: a short natural gas line that taps off the existing line that runs past the building, rerouted

15”, 18”, and 24” storm drain piping, water service lines, a steam line, and sanitary sewer lines.

Soil was tested by a third party, and the resistivity was found to range between 3300 and 5100 ohm-cm with a pH of 8.1-8.2. The sulfate and chloride levels were found to be low (between 62-69 ppm not detectable respectively). This classifies the soil as having mild corrosion potential.

According to UFC 3-570-01, certain lines require cathodic protection on metallic components regardless of the soil resistivity. In this project, the lines that fall under this criteria are the natural gas line, water service lines, and metallic (cast iron) industrial waste and sanitary waste piping underneath the building slabs. This also includes metallic components on non-metallic lines, such as the fire hydrant.

The unstable soils on this site have required some design considerations that also must be addressed with cathodic protection. The cast iron piping under the building must be supported at five-foot intervals over its entire length. Since the pipe supports are an integral part of the piping design and are critical components associated with the under-slab cast iron, they have been included in the cathodic protection design.

Requirements on all other lines; the storm drains, steam line, and sanitary sewer lines, are at the discretion of the designer whether or not it is economically feasible to install cathodic protection on the metallic components. Due to the mild corrosion nature of the soil in the area as well as the materials selected on these lines, at this time it does not seem economically necessary to provide cathodic protection to these portions of these lines.

The cathodic protection requirement includes any metallic fittings on restrained piping, as well as the fire hydrant/valve assemblies or any under slab piping and valve assemblies. Each metallic assembly not under the building slab will require individual anodes, or in some cases, multiple anodes combined with a test facility

(test station) and a connection wire/cable to each fitting. If necessary, in areas where there are multiple metallic fittings in close proximity, anodes and structure leads can be terminated in the same test station.

Bond Cables will be run from each metallic assembly for the corresponding test station, and the components will be bonded to the anode header cable(s) in the test station. This will minimize the number of required test stations while still allowing the individual components to be tested for cathodic protection levels.

It is important that the anodes are buried below the fittings in native soil if possible, or as a minimum, in the soil layers with permanent moisture levels. This is usually about 12” below the bottom of the fitting or hydrant assembly.

All metallic fittings and under slab cast iron piping has been specified to have a 35-mil polyethylene backed butyl rubber tape coating. This serves two purposes: first to separate the piping from the soil electrolyte and, second to reduce the bare surface area of the pipe to a minimum so that its current requirement for protection is reduced to a manageable level.

The anodes chosen for this design (other than the pipe support hanger anodes) are all 17 lb high potential magnesium anodes (Type 17D3).

Nine-pound anodes (Type 9D3) will be added to each pipe support to provide protection to the steel hangers. In addition, an FRP pipe shield shall be installed between the pipe and the hanger to keep the pipe isolated from the hanger and to protect the integrity of the coating.

Performance Requirements:

Provide cathodic protection to metallic underground utilities in accordance with UFC

3-570-01 and NACE SP1069 – Control of External Corrosion on Underground or

Submerged Metallic Piping Systems.

Operation and Maintenance:

i. Initial Baseline Potentials: After backfill of the pipe, but prior to the connection of the anodes, the static potential-to-soil of the pipe shall be measured.

ii. Initial Anode Output: As the anodes or groups of anodes are connected to the pipe, measure the current output of each anode (or anode group).

iii. Potential Measurements: Upon completion of the installation and with the entire cathodic protection system in operation, electrode potential measurements shall be made using a copper-copper sulfate reference electrode and a direct current voltmeter. Potentials shall be taken at locations identical to the baseline test.

iv. Annual Potential Measurements: Potential measurements shall be repeated on an annual basis in order to ensure continued performance of the cathodic protection systems.

d. Structural Systems

Load-bearing masonry and precast concrete walls provide a durable structure for this industrial facility. Due to settlement concerns, the building and ground floor slab are supported on deep pile foundations. Structural steel and open-web steel bar joists frame the roof. Metal roof deck acts as a diaphragm, distributing lateral loads to the shear walls and foundation.

e. Antiterrorism Systems

Inhabited portions of the building must comply with UFC 4-010-01 Chapter 3

Standards. An unobstructed space must be provided around the inhabited section, with all exterior doors opening outward. Exterior masonry walls are reinforced, and the inhabited section is structurally isolated from the remainder of the building.
