CHAPTER 2 CIVIL

2-1 GENERAL

Per observed drainage patterns of the existing topography and tributary area delineation, significant offsite runoff, and runoff from the east side slope of the building is collected in the existing swale running along the north side of B3524. The 5 feet width x 3.5 feet height earthen berm with masonry wall adjacent to the swale functions as a floodwall diverting the offsite runoff downstream. There are three (3) openings along the earthen berm for access to the building. The finish grade of the opening is flush with the adjacent grade of the slope, enabling off-site runoff to enter the site. Installing barrier berms at the openings would be a cost-effective flooding control measure to eliminate additional off-site runoff entering the site and accumulating in the existing swale.

Observed watermarks appear at the open area between the edge of the building and the earthen berm north of the building. Temporary ponding of stormwater occurs in the area due to limited capacity of the existing earthen swales and drainage system.

In addition to stormwater detention at existing swale, the adjacent B3531 located downstream has flooding issues during major storm events. The downstream storm drains discharge to a nearby creek next to Halyburton Street, and watermarks are observed at the catch basins at the parking lot upstream of the discharge point.

Most likely, the downstream storm drains are undersized to handle the peak flows, and the surcharged storm drain reached its capacity causes stormwater detention within the local depressed area between the building and the sloping berm.

2-2 APPLICABLE CODES

See Section 1-3.

2-3 BASIC DESIGN INFORMATION

Hydrology and hydraulic analysis shall be performed to estimate the peak flows that contribute to the site for storm drain system upgrade and flood control.

Evaluate and determine the Best Management Practice (BMPs) system with onsite stormwater detention system, flow diversion, or increase storm drain system capacity downstream.

2-4 CALCULATIONS

TR-55.

Perform hydraulic analysis to determine/verify capacity of existing storm drain system per

HDS-5.

CHAPTER 4 STRUCTURAL

4-1 GENERAL

4-1.1 Existing Conditions

The existing structure was constructed around the year 1967. It is a one-story building with a low sloped reinforced concrete roof supported by concrete beams and columns.

The perimeter walls and most interior walls are CMU load bearing shear walls. The walls bear on shallow concrete strip footings. Shallow spread footings support concrete columns and are connected to adjacent wall strip footings with tie beams. There is a large ground floor mechanical room with exterior access, and three mechanical rooms in CMU-walled penthouses on the roof. The portion of roof above the auditorium is constructed of long span concrete beams, upturned so the tops of the beams extend up above the roof slab. The center section of the building is similarly covered by upturned concrete beams.

In addition, that roof slab was constructed to be lower than the surrounding roof, with sloping surface and drainage holes through the upturned beams all leading to one center drain. A corrugated galvanized steel roof was added in 1982 above that roof to shed water.

The existing structure has extensive concrete spalling in the roof slab due to corrosion expansion of reinforcement. The spalling is significant in the un-conditioned mechanical room, and in Rooms 188 and 120-121. There are smaller spalls and concrete delamination at several other locations. Fiberboard insulation is fastened to the underside of the roof slab, holding moisture to the roof, and hiding any spalling. Most interior spall locations were observed located below small roof penetrations, areas with ponding, and/or rooftop equipment anchor points. The spalling appears to be limited to the roof slab, with minimal spalling observed in beams and columns. The exception to this is the concrete beams in non-conditioned spaces, such as the mechanical room and penthouses were observed to have significant deterioration and spalling. The CMU shear walls appear to be in structurally acceptable condition. The slab-on-grade appears to be in satisfactory condition with one exception where the slab appears to be cracked and bulging up.

The spalling issue has caused the occupants of the building to be evacuated to other locations and the building is mostly vacant. Samples of the roof slab concrete at this building were obtained in January 2024 and have undergone laboratory testing to determine the concrete properties. Testing of the samples includes chloride content, petrography, compressive strength, and carbonation. A testing report has been produced for this investigation which states the structural deterioration is mainly attributed to carbonation of the concrete. The concrete has become carbonated due to the age of the structure, a poor building envelope, prolonged exposure to the elements and a lack of preventative maintenance. The process of carbonation is irreversible and difficult to stop in the presence of moisture. For perspective, it could take approximately two years for the roof slab to dry out if the roof envelope is repaired and the underside of the roof slab concrete is exposed to conditioned air. As such, additional spalling and deterioration is anticipated.

These spalls can injure occupants and equipment below. In addition, this loss of concrete thickness and reinforcement cross section results in a loss of flexural and shear capacity of the concrete slab. Over time such loss will progress to cracking, allowing more water penetration and deterioration, leading to additional concrete section loss. This increases the chances of a possible failure of the structural system during an event such as a heavily loaded maintenance repair, typhoon, or earthquake.

In addition to the concrete spalling issues, there is significant cracking in the CMU at the three rooftop penthouses. There is also significant leaking where the lowered center section roof meets the walls at the surrounding hallway.

The roofing is a reinforced, fluid-applied membrane. The roofing membrane exhibited signs of wear, brittleness, and has reached the end of its useful life.

4-1.2 New Work

Structural work will vary based on the COA that is chosen. See section 4-2 below. Scope will involve designing and detailing new concrete, steel, and CMU construction, and repairs to any existing to remain. Nonstructural systems including Ceilings, Piping, and Mechanical systems will require seismic bracing.

4-1.3 Applicable Codes

See Section 1-3.

4-2 BASIC DESIGN INFORMATION

Due to the spalling issues, New Work can involve:

4-2.1 COA 1: Roof Replacement

Demolish the entire roof and concrete beams down to top of existing CMU walls - leaving walls, slab on grade, and footings in place. Where wall heights vary, new CMU or concrete can be added to achieve a consistent elevation. The roof will be rebuilt while keeping existing concrete columns and CMU shear walls in original locations above existing grade beams and footings.

The roof can be replaced with a new cast-in-place concrete slab; precast structural elements, such as hollow core slab or double tees topped with a concrete topping; or steel joists and metal deck. New connections and rebar will be doweled into the existing CMU and concrete, using an adhesive anchoring system.

The design and construction of the existing CMU walls, concrete columns, and footings will be evaluated to ensure that they are not overloaded and can meet the lateral load capacity requirements of IEBC, AISC 41, and RP 10. New shear walls, columns and footings may need to be added as required by the Code. Select interior walls can be demolished as needed by Architectural requirements, but for the most part the existing wall layout will remain. The existing mechanical penthouses will be demolished and

CHAPTER 5 MECHANICAL

5-1 GENERAL

The SOW Operations Building, B3524, is experiencing major structural degradation.

There are three (3) COAs that are being evaluated for addressing the structural issues and all three (3) COAs involve the complete replacement of the HVAC and Plumbing systems in the existing facility or providing all new HVAC and Plumbing systems in a new facility. Based on the current condition of key HVAC and plumbing components, the replacement of much of these systems is indicated, regardless of the structural situation.

Although some components have been replaced recently, those components will likely be repurposed at other facilities based on the timeline for reconstructing or replacing this building. Currently, there are four air handlers on the roof in penthouse structures. There is a desire to move all air handling units to the ground, for ease of maintenance and protection during storms. This will require the construction of ground level Mechanical Rooms, either within the existing building footprint or as additions to the building. There is no available space on the ground on the south and west sides of the existing building footprint for new additions, and there is limited space on the east side of the building. Most of the new Mechanical Room construction is limited to the north side of the building or new Mechanical Room space can be set aside within the existing building footprint.

5-2 FUNCTIONAL AND TECHNICAL REQUIREMENTS

5-2.1 Applicable Codes

See Section 1-3.

5-2.2 Design Temperatures

HVAC loads should be based upon the local design weather values. For Kadena Air Base on Okinawa, Japan the following values are recommended:

Outdoor Design:

Summer Conditions: 91.3°F dry bulb ASHRAE 1% DB 80.3°F wet bulb ASHRAE 1% MCWB

Winter Conditions: 50.3°F dry bulb ASHRAE 99.6% DB

Indoor Design:

Summer: 78°F dry bulb 50% relative humidity

Winter: 68°F dry bulb

0-50% relative humidity side. There are existing issues with sewer flow within the building, with some underfloor sanitary sewer lines suspected of having sunk into the ground causing back-ups. There are currently Men’s and Women’s group toilets in the building’s southwest area, but only a single Men’s room in the northeast area. Based on system condition, age and the proposed COAs extensive construction impacts, all existing plumbing within the building footprint will be removed, including all under floor piping.

Any redesign should address the inequity of restrooms available for all occupants.

Domestic and sanitary sewer connection points will be provided from the utilities surrounding the building. All new domestic cold and hot water piping will be provided below the floor, in walls and above the ceilings. All new sanitary sewer piping will be provided below the floor, in walls and above the ceilings, with venting through the roof. All restroom fixtures will be new in any restoration and modernization of the existing building, including water closets, urinals, lavatories, and showers. New water fountains will be provided at restroom locations. New electric tank type or instantaneous water heaters will be provided where hot water is required.

Seismic restraints will be required for equipment, piping, and ductwork in the building. The Seismic Design Category, Risk Category and Site Class as determined by the Structural Engineer must all be considered when determining which components need seismic restraints.

Provide complete O&M information at the end of the project, including warranty information for all new equipment.

5-4 CALCULATIONS

A detailed analysis of the building is required to determine the final sizing of the new HVAC equipment. This analysis will use local weather data and information about the number of people, equipment, and lighting in each room. The building envelope construction will be updated as part of the building reconstruction and used in the HVAC load calculations.

The detailed analysis will determine the equipment size required, and the appropriate distribution of the cooling to all areas of the building. Loads will be calculated using a computerized program that uses ASHRAE Fundamentals methods of calculation. High Performance and Sustainable Building (HPSB) practices, as outlined in UFC-1-200-02, must be followed.

5-5 COORDINATION WITH INSTALLATION OR OUTSIDE AGENCIES

The building will have a DDC system that communicates using the BACnet protocol and will communicate to the base-wide Energy Monitoring and Control System (EMCS) over the Base CE VLAN to Building 1474 (B1474). Cybersecurity will be integrated into the DDC system, especially for the tie-in to the EMCS. Utility meter monitoring will be included per the requirements of the Kadena Design Guidelines.

CHAPTER 6 ELECTRICAL

6-1 GENERAL

6-1.1 Existing Conditions

The facility's existing electrical system consists of a 120/208V, 3 Phase, 4 Wire, 2000A switchboard powered from a 500 kVA unit substation with a 1200A circuit breaker located just outside of the building.

The switchboard consists of Bus A, for normal building loads, and Bus B, for emergency building loads. Bus A is powered from the 500 kVA unit substation via a 1600A main circuit breaker in the switchboard. Bus A is connected to a 208V, 600A, 4 Pole, 60 Hz, automatic transfer switch (ATS) via a 600A circuit breaker.

This ATS is connected to a 150 kW, 120/208V, 3 Phase, 4 Wire, 60 Hz, diesel emergency standby generator and to the Bus B side of the switchboard via lugs only.

Switchboard Bus A provides power to a wire gutter, which provides power to rooms 116, 135, 178, and 193, and to motor control center (MCC) MCC A, which powers chiller units, chilled water pumps, and an air handling unit.

Switchboard Bus B provides power to several panelboards and air handling units, and provides power to MCC B, which provides power to the fire alarm system, roof vent, and a few existing loads. Bus B is the facility’s emergency circuit, providing power to all areas of the SCIF and parts of the JAOC area and HVAC system. Unfortunately, not all areas of the JAOC and HVAC system are powered from the emergency circuit, as would be preferred.

The switchboard, MCC A, and MCC B are in extremely poor condition and pose a serious safety hazard for any personnel working on or near the equipment. The equipment is covered in rust with large holes in the front plates. Exposed electrical wires, circuit breakers, and more can be seen and easily reached. Some electrical compartment doors on the motor control center are unable to close.

It is unclear exactly how old the switchboard and MCCs are, but they are over 30 years old and may be around 50 years old. Modifications in 2011 replaced the old generator with the current 150 kW Caterpillar generator and 600A Caterpillar ATS. Based on visual inspection and age, the ATS and generator appear to be in fair condition and could be reused or repurposed. The 1,000-gallon diesel fuel tank, located outside, was not replaced during the modification project.

Panelboards throughout the facility appear in acceptable condition due to being in a climate-controlled environment but are likely close to the end of their useful life.

While light controls appear older, during the site visit, it appears all fluorescent lights were replaced with LED lights.

6-3.2 Other Coordination Considerations

Coordination with the electrical utility is required to turn off the upstream unit substation circuit breaker prior to construction, demolish from and reconnect to the new system, and reenergize the system once construction is complete.
