7.1 OVERVIEW

This project will replace the existing air handling units serving the sixth floor wards, 6J and 6K.

Previous projects have modified the existing air handling units and wards 6J and 6K are experiencing temperature and humidity issues. The hospital is reclassifying wards 6J and 6K as

“COVID” wings, and require the patient rooms to be negative pressure relative to adjacent corridors. The SOW has directions that the units shall be 100% outdoor air units.

7.2 CODES AND STANDARDS

The following is a list of VA and other design and construction criteria that shall be utilized by the

A/E for the development of the design of this project:

a. PG-18-1, Master Construction Specification Index

b. PG-18-3, Design and Construction Procedures

c. PG-18-4, Standard Details and CAD Standards

d. PG-18-10, HVAC Design Manual – 2017

e. ASHRAE Standard 62.1 – 2016

f. ASHRAE Standard 170 – 2013

7.3 MECHANICAL DESIGN APPROACH

Each area will be analyzed to meet the design approach requirements in the DVA, “HVAC Design

Manual” dated November 2017.

EXISTING CONDITIONS:

The existing variable air volume air handling units serving 6J and 6K will be removed from

Mechanical Room, 6K112. Existing supply, outdoor and exhaust air ducts within the mechanical room which are attached to the existing air handling units will be removed. Existing duct-mounted and roof-mounted exhaust air fans serving wings 6J and 6K will be removed and their corresponding roof openings will be reused by new exhaust air ducts. The existing 4” chilled water pipe will be removed and replaced with a 6” chilled water pipe inside the mechanical room. New chilled water isolation gate valves will be provided. Existing 2” steam piping and corresponding steam condensate pipe riser shall remain and be reused. Existing outdoor air louver located in the mechanical room will be reused. Existing hot water risers and associated piping will remain and serve the VAV boxes located throughout wings 6J and 6K.

OLIN E. TEAGUE VAMC: A/E Design Services to Replace AHUs BLDG. 204; Ward 6J-6K

PROPOSED SYSTEM:

New constant volume air-handling units with 100% outdoor air, chilled water cooling coils, steam heating coils will be provided to serve wings 6J and 6K. New AHU-6J will be capable of providing

22,000 cfm of supply air to wing 6J and new AHU-6K will be capable of providing 18,000 cfm of supply air to wing 6K. Outdoor air will be ducted from the existing outdoor air louver on the east wall of mechanical room 6K112. Exhaust air from the sixth floor will be ducted to the mechanical room and exhausted up through the roof through existing roof openings. HEPA filters will be provided in the air handling units and in the exhaust air duct system upstream of the exhaust fans in the mechanical room. Chilled water coils will have new insulated piping that connects to existing chilled water risers. Steam preheat coils will have new insulated piping that connects to existing steam risers. Supply and exhaust fan sections will be comprised of fan arrays to reduce air handling unit footprint size. Supply and exhaust fans will utilize variable frequency drives. New air handling units shall be provided with freeze protection. The new air-handling unit DDC controllers shall be compatible with the existing building EMCS (Johnson Controls Metasys System).

AHU OPTIONS:

Several air-handling unit types were evaluated; AHUs without energy recovery, AHUs with flat plate heat exchangers, and air-handling units with a run-around coils.

Air handling units without energy recovery do not have the capability to mix air streams and are small enough to fit in the existing mechanical room. However, cooling coil and heating coil capacities increased because of the lack of preconditioning the outdoor air.

Air handling units with flat plate heat exchangers reduce the possibility of mixing air streams, but the size of the units makes it prohibitive to use inside the existing mechanical room.

Air handling units with run-around coils can fit within the existing mechanical room, but only affect sensible loads. The size of the coils that would be proposed in the outdoor air intake and exhaust air stream are physically too large to be installed in the existing mechanical room. Smaller coils would not transfer an adequate amount of heat to be feasible.

The existing mechanical room size, availability of chilled water capacity, and water flow influenced our decision to choose air-handling units without energy recovery. The units will be providing air to areas with airborne infectious diseases, therefore any energy recovery that introduced the potential for air leakage was prohibited. The VA Design Guide also prohibited Energy Recovery

Wheels for isolation or airborne infectious rooms.

OLIN E. TEAGUE VAMC: A/E Design Services to Replace AHUs BLDG. 204; Ward 6J-6K

The existing air-handling units were VAV type units. The new design for the patient rooms will provide a constant 12 air changes to those rooms. The amount of variable airflow will be limited to approximately 20-30% of the designed supply air flow. Varying the amount of supply airflow could also impact the amount of exhaust air in other parts of wings 6J and 6K, which could put the negative pressure conditions for the patient rooms in jeopardy. After discussing these issues with the VA, it was decided that a constant volume air system would be a better fit to achieve the negative pressure requirements for the patient rooms.

AIR DISTRIBUTION:

A test and balance of air handling units and associated supply, return, and exhaust air ducts serving wings 6J and JK shall be performed prior to any construction. The air distribution system will be balanced in accordance with original construction airflow rates. There is a concern that the previous renovation to the air handling units may restrict airflow to all the rooms, and balancing them to those airflow rates will lead to heating/cooling issues after this renovation.

PATIENT ROOMS:

Patient rooms will be provided with a minimum of 12 air changes per hour of conditioned outdoor air. Exhaust air will be pulled from the patient rooms to maintain a negative pressure to the adjacent corridor. Exhaust air duct above some of the one-bedroom and two-bedroom patient rooms shall be removed and replaced with appropriately sized ductwork and accessories. Ceilings in those areas will need to be removed and replaced to accomplish the work. Existing VAV boxes serving the patient rooms will be replaced with new appropriately sized VAV boxes. New VAV boxes shall have hot water reheat coils. Existing ceiling diffusers and grilles will be evaluated if they can be reused. Each VAV box shall be controlled by an existing corresponding wall-mounted temperature sensor.

PROPOSED COST DEDUCTIONS:

1. Only install new controls, valves, and accessories for new VAV terminal units.

2. Select less efficient roof-mounted exhaust fans that does not incorporate plume discharge heights in the design. Use different type of exhaust fan, provide new stack and support accessories.

ELECTRICAL

9.1 OVERVIEW

The project Scope of Work is to renovate existing air handling systems. The electrical scope of work includes demolition of existing and replacement of electrical connections to air handling equipment including, but not be limited to, power and power distribution. Design will be in accordance with VA-adopted codes and standards including VA Directives, Design Manuals, Master Construction Specifications, Design Criteria and other Guidance on the Technical

Information Library.

9.2 CODES AND STANDARDS

The following is a list of VA and other design and construction criteria that shall be utilized by the

A/E for the development of the design of this project:

• PG-18-1, Master Construction Specification Index

• PG-18-3, Design and Construction Procedures

• PG-18-10, VA Design Manuals

• ANSI C2, National Electrical Safety Code

• IEEE 141, Recommended Practice for Electrical Power and Distribution for Industrial

• IES Handbook, Illuminating Engineering Society Handbook

• ANSI/TIA/EIA-568-B, Commercial Building Telecom Cabling Standard

• ANSI/TIA/EIA-569-B, Commercial Building Standard for Telecom Pathways and Space

9.3 ELECTRICAL DESIGN APPROACH (POWER)

Electrical evaluation and design will be provided to support

All power wiring will be copper with type with THHN/THWN insulation. Conductors #10 and smaller will be solid, conductors #8 and larger will be stranded. Minimum size conductor will be #12 AWG for power circuits and #14 AWG for control wiring. An insulated equipment grounding conductor will be provided for all circuits.

OLIN E. TEAGUE VAMC: A/E Design Services to Replace AHUs BLDG. 204; Ward 6J-6K

Existing circuits serving replaced air handling equipment on the 6th floor will be replaced.

1. New disconnect switches, combination starters, variable frequency controllers will be designed.

2. Removed devices will be turned over to the Owner.

3. New 480 Volt, 3-phase circuits will be designed.

4. The existing electrical equipment in the mechanical room is fed from an existing branch panel “6KM” and taps off of a circuit in a wireway. The panel and wireway circuit are each fed from separate 200/3 fused plug-in disconnects on a 480/277V, 600A bus duct in the electrical room. The existing bus duct supplies the hospital equipment branch essential systems and is backed up by generators at the Central Plant Building 203.

5. The existing branch panel serving the mechanical space does not have capacity to support the new equipment. A new branch panel will be designed. A new feeder to the new panel will be designed. The feeder will extend to the existing source.

6. The capacity of the existing equipment branch bus duct is insufficient to accommodate the new loads. By observing the existing meters in the first floor main electrical room, the peak load on the equipment branch circuit is 420KVA. According to NEC 220.87, before adding new load to the circuit we need to take 1.25% of the peak load and subtract that amount from the busway capacity. The remaining capacity is available for use in new circuits. For this busway, 420 x 1.25 = 525 KVA, 525 / 0.831 = 632 Amps.

The existing equipment branch busway is only rated for 600 Amps. Therefore, there is no available capacity for the additional loads on this busway. Adding load to this busway is not allowed by code.

7. The equipment branch busway is fed from a 600 Amp circuit breaker in the first floor main electrical room. This circuit breaker will be replaced with a 1000 Amp circuit breaker. The existing busway will be disconnected and a new feeder from the new circuit breaker will be routed to a new 1200 Amp distribution panelboard with two 600 Amp circuit breakers. One of the new 600 Amp circuit breakers will feed the existing 600 Amp equipment branch busway. The other 600 Amp circuit breaker will feed the new panel “6KM”.

8. The existing equipment branch feeder from the Central Plant Building 203 is indicated to be 3 sets of 500 KCMIL conductors. These conductors are capable of providing 1140 Amps and were oversized to accommodate voltage drop. The estimated new loads on the circuit is 593 KVA. The length of the circuit is approximately 500 lf. The voltage drop on the circuit at full load is 1.9%.

9. The Equipment Branch ATS #3 in the Central Plant Building 203 is rated at 1000 Amps.

10. The equipment branch circuit breaker for the hospital building is only rated at 600 Amps. This circuit breaker will be replaced with a 1000 Amp breaker.

11. Space appears to be available in the existing electrical equipment to accommodate the new circuit breakers. However, where circuit breakers in existing switchboards are being replaced, the Contractor still need to field verify the available space in the existing equipment.

APPENDIX A1

QUALITY ASSURANCE / QUALITY CONTROL

PLAN

A1.1 QUALITY ASSURANCE / QUALITY CONTROL

OVERVIEW

The Construction Specifications Institute (CSI) defines quality assurance (QA) during design as “the procedures for guarding against defects before and during the execution of the work.” Quality Control

(QC) during design is defined by CSI as “the procedures for evaluating completed activities and elements of the design for conformance with requirements.” CB Design follows basic principles we have developed over many years of practicing architecture.

Do It Right the First Time

• Quality is achieved not by merely finding mistakes and correcting them, but by refining the process over time to prevent mistakes from happening in the first place. Our Quality Control committee meets regularly to discuss issues, procedures and guidelines to improve our process.

Never Make the Same Mistake Twice

• Before drawings are released, we use checklists composed of issues that have been addressed and resolved on similar projects. At the project kick off we gather your lessons learned and integrate them into our QA/QC checklist, so we don’t repeat mistakes of pervious teams.

Two Heads Are Better Than One

• At the completion of each phase of the work, the drawings and specifications are reviewed by our Design Review Committee. A fresh set of eye can uncover issues which need further clarification.

Execution

• All team members do internal QA/QC checks before sending their drawings and specifications to CBDG for overall coordination and final QC check.

• CBDG maintains and adds to a QC Manual that is shared between team members. This has been developed over our many years of experience.

QUALITY ASSURANCE

QA starts with hiring qualified staff and continually training staff to be current with the latest design and construction technologies. For project specific QA, the first step is to review and understand the owner’s program and seek clarification on any ambiguities.

Other QA processes include:

OLIN E. TEAGUE VAMC: A/E Design Services to Replace AHUs BLDG. 204; Ward 6J-6K

• Assigning a Project Manager/Architect throughout the lifecycle of the project

• Reviewing codes

• Reviewing regulatory agency regulations, ordinances, standards

• Reviewing owner’s design guidelines

• Participating in regular coordination and progress meetings

• Reviewing owner provided information

• Reviewing consultant provided information

• Teaming with qualified consultants

QUALITY CONTROL

CB Design implements several quality processes at each phase of the design that fall within the area of

QC, including:

• Principal level involvement throughout each phase of the project

• Reviewing cost estimates to ensure project design aligns with budget

• Internal reviews of design and design documents

• Code plan reviews by each discipline lead

• Using AIA Document D200 – Project Checklist

• Using project specific checklist based on owner’s requirements (Supplement B to SF 252)
