I. Executive Summary

A. Goals and Needs:

1. The primary objective of the Project is to restore the Laundry Building (Bldg 45) to an operational facility. The building is located at the Veterans Affairs Medical

Center (VAMC), 940 Belmont Street, Brockton, MA. The building has been dormant for several years. An earlier project was partially completed, then terminated for convenience due, in part, to the discovery of unforeseen structural issues with the building. The original building was constructed in 1951 with subsequent additions through 2019 for a total area of 41,473 sf +/-. The aforementioned project involved the Civil engineering-related work, re-roofing, replacements of exterior doors and windows, renovation of laundry processing areas, office areas, employee lounge and locker rooms, and all Fire Protection, Plumbing, Mechanical, and Electrical, & systems.

2. The replacement of all Laundry Equipment was planned to be provided under a separate contract which was in place when the Project was suspended. The

Laundry equipment included in the previous design was purchased by the VA, but not installed. It is currently being stored offsite and is planned to be installed under a separate, future contract for this Project.

3. Doors, windows, and roof have been replaced as components of previous projects and are considered well within the span of their useful life. Thus, no work to the exterior of the of the building, except minor repair or Mechanical work is anticipated.

4. The project’s scope of work excludes civil engineering-related design and construction. As such, all civil, survey, landscape, Geotech, and any other design and survey work is excluded.

5. The Project design seeks to resolve structural issues with the building and complete the work, based as closely as practical, on the design concept developed for the prior Project. The design will consider retaining previously installed architectural and engineering work to recoup maximum value from that initial investment.

However, installed work that has deteriorated since installation will typically not be retained.

6. The adequacy of the previous design will be analyzed for current and future needs. Code conformance for this design will also be re-examined.

Recommendations for improvements will be made for Owner consideration as practical.

7. Due to the length of time the building has lain dormant, Much of the HVAC equipment, which was never been started, has become unwarrantable and could be subject to replacement. It has also been noted that much of the new Plumbing work was not installed in a code compliant manner and should be corrected. The

Page I - 2

VA has agreed to take responsibility for retro-commissioning any new existing equipment retained from previous projects. If it is determined this equipment remains unwarrantable, the VA has agreed to take responsibility for its use and any maintenance issues that ensue.

8. The structural issues referenced above primarily concern the floor of the main laundry area in the original 1951 building. Options for addressing these issues were vetted and further discussed in the Structural Narrative included with the DD1

Submission. As such, it has been determined there is only one viable option for remediation. This solution has been further developed and is represented in the

Structural Drawings and Specifications included in this submission.

9. The previous design concept envisioned a fully functioning self-contained laundry facility including washing, drying, folding and preparation. Soiled and Clean areas will be fully separated and full access for both receiving and shipping is anticipated.

10. The Project is intended to restore the VA’s ability to perform all laundry services provided to VISN 1 by Brockton. Currently these services are being performed off-site by outside vendors.

11. The Design includes support spaces for staff such as lockers, changing and lounge spaces. These spaces were largely completed during the previous project, however suggestions for maintenance and repair items will be included in our Project. As noted above, code compliance issues have been noted in these areas that will require correction. Since it has been determined that the only feasible structural remediation solution will require overhead work in these areas, existing ceilings, HVAC systems, Fire Protection systems, and Electrical work will require removal and replacement. Any work discovered that is not code conforming must be brought up-to-code as it is reinstalled.

12. The building is currently out of service and not connected to any other part of the facility. Thus, no isolation or maintenance of any ongoing services are anticipated.

We have not included any efforts for Abatement Air Monitoring or final clean closure.

13. The Project should be constructed in two informal phases as noted below.

Scheduling and any overlap of these phases is at the Contractors discretion:

a. The initial phase will include the remediation of structural deficiencies.

b. A secondary phase will include construction of all interior architectural, fire protection, plumbing, mechanical, and electrical systems needed to support the laundry facility.

c. The final phase would include the installation of laundry equipment under a separate contract. Though this project is designed around this existing equipment, the delivery and installation of this equipment is NOT to be included in this project.

Page I - 3

14. Commissioning: The VA previously confirmed that Commissioning was not required for this Project. However, it has since been determined that limited retro-commissioning will be required. See Specification Section 019100 for further details.

15. Coordination with SHPO was not required as part of this process prior to this phase.

However, based on further investigations, it has subsequently been determined that submission and review by SHPO is required. Drawings have been submitted and the results of that review require no further action.

16. While we incorporate sustainable design elements, when possible, LEED/Green

Globes/other green initiatives are not required as a function of this design.

17. We have anticipated all utility work will be internal to the building.

18. Life Cycle and energy modeling services are excluded.

19. The Final Project Design Documents include Drawings and Specifications for use by the Government in soliciting bids to complete the construction of the Project utilizing a Design/Bid/Build delivery process.

B. Project Budget Estimate

1. The original Estimated Construction Cost (ECC) indicated in the Statement of Work is

$4,000,000.

2. A detailed cost estimate was developed based on the Schematic Design Submittal

Documents

3. The Estimated Construction Cost (ECC) based on the Schematic Design Documents was

$7,714,566.

4. The Estimated Construction Cost (ECC) based on the DD1 Design Documents is $6,993,721.

5. The Estimated Construction Cost (ECC) based on the DD2 Design Documents is $8,849,449.

This increase reflects the more detailed design work available during this phase in the

Plumbing Mechanical & Electrical trades.

6. The Estimated Construction Cost (ECC) based on the FINAL Design Documents is $8,841,724.

C. Project Schedule

1. A copy of the current Project Design Schedule is Provided as Appendix F3.2. This schedule, (REV 6) submitted with this CD package, is still valid and the project remains on this schedule.

IV. Structural

A. Goals and Needs:

1. Structural work on this project includes analysis of the existing floor and roof structure to support new laundry equipment at Building 45 at the Brockton VA Medical Center. The design shall be based on all

VA and state building code requirements.

B. Existing Conditions

I. The existing building is a multi-story concrete and steel framed building that was constructed over multiple eras starting in 1951 and ending in 2019.

The original building constructed in 1951 consists of reinforced concrete floor first floor slab supported by reinforced concrete beams. The roof of the original building is constructed of concrete roof deck supported by structural steel roof trusses. The steel roof trusses are supported by wide flange steel columns founded on the first floor. The steel columns and concrete floor framing are supported by reinforced concrete columns down to the reinforced concrete isolated footings. The basement level floor is constructed of reinforced concrete slab on grade.

A new multistory structural steel framed addition was added to the south side of the original building. The roof of the addition consists of metal deck supported by open web steel joists. The joists are supported by structural steel beams. The first floor is constructed of concrete filled metal deck filled supported by structural steel beams.

The steel roof and floor beams are supported by structural steel columns and founded on reinforced isolated footings.

Several additions of unknown age were added as the original structural drawings are not available. Steel framed additions were added to the west and north sides of the building. Two metal building structures were added to the north and south side of the previous additions mentioned above.

In 2020 ZA Engineering conducted a structural investigation of the existing first floor slab conditions as well as as-built structural analysis of the first floor based on their in-situ findings. The results of the study indicated that the first-floor slab could only support an 88 psf

Dead Load and a 78 psf Live Load. This live load is much below what would be expected by code for a laundry facility which would be a minimum of 100 psf. While we concur with the findings, the original analysis did not appear to evaluate the first floor beam system. Based

Page IV-2 on our preliminary analysis these beams also cannot support the required live loads.

Retrofit of the existing first floor will be required in order to use the existing first floor to support the new laundry equipment. Based on analysis and discussions with the VA we are moving forward with the retrofit approach shown below.

1. In-Situ Reinforcement:

a. Provide new supplemental steel beams between existing concrete beams to support the existing slab and reduce the existing slab spans. This will require compete access to the underside of the existing structure and will likely require demolition of existing ceilings and MEP components such as ductwork and piping.

b. Enlarge/Deepen existing concrete beams to support the new slab equipment and live loads. Deepening the beams will require new reinforcing at the bottom of the beam and addition of 6” of concrete be added and bonded to the existing concrete beam.

c. This option provides the best blend of construction feasibility and consideration for requirements of the new equipment.

d. Minimizing movement of existing components supported by this floor make this option the least feasible.

C. Scope of Structural Demolition:

1. Partial basement slab demolition.

2. Partial non-bearing wall demolition to enlarge existing openings.

3. Partial first floor demolition to install new chase

4. Partial roof feck demolition to install new roof penetrations

5. Demolish existing cut bar joists.

D. Scope of New Structural Work:

1. Install new structural steel framing between existing concrete beams below the existing floor slab.

Page IV-3

2. Enlarge the depth of the existing concrete beams via new rebar and concrete installation.

3. Install new carbon fiber reinforcing and steel rebar shear reinforcing.

4. Install new footing enlargement concrete.

5. Install column reinforcing steel.

6. Install new floor decking in areas of deteriorated floor decking.

7. Install new basement slab on grade.

8. Install new lintels at enlarged openings.

9. Install new steel beams to replace existing cut joists.

10. Install new stair foundation.

11. Install new stair framing.

12. Install New Masonry wall and wall footing.

A. Design Requirements

1. The primary objective of the Project is to restore the Laundry Building (Bldg. 45) to an operational facility. The building has been dormant since 2016.

2. Programming and Conceptual Design: The Design Scope of Work is generally based on the Statement of Work & associated attachments and discussion received during the Kickoff Meeting with VA Stakeholders on November 21, 2022.

Subsequently, the AE SOW was expanded to include laundry consulting services to coordinate the design of architectural and engineering systems including structural remediation.

3. The base building was constructed in 1951 with subsequent additions in 1975, 1983, 1997, 2008, 2016, & 2019 for a total area of 41,473 sf +/-.

4. An earlier project (2016) was under construction and was terminated for convenience.

5. In 2019, an addition was constructed which added new switchgear, panelboards and other electrical gear in a new attached building. This addition circumvented the Electrical design incorporated in the 2016 Project and included emergency power.

6. The 2016 project, which was not completed, involved the addition of Office and

Receiving areas and the complete renovation of the Main Laundry area, employee lounge and locker rooms, and all Mechanical, Electrical, Fire Protection &

Plumbing systems. All demolition work was completed as well as the renovation or addition of Receiving, Offices, Lounge, and locker rooms. The current Project will complete the design of these remaining areas utilizing durable and efficient materials and systems.

7. The previous design concept envisioned a fully functioning self-contained laundry facility including washing, drying, folding and preparation. Soiled and Clean areas will be fully separated and full access for both receiving and shipping is anticipated.

8. The Current Project will include a review of ALM Laundry Infection Prevention

Control Guidelines and HLAC 2023 Accreditation Standards. Built elements will be incorporated as applicable.

The current Project design seeks to resolve structural issues with the base building and complete the work, based as closely as practical, on the most recent design concept. The objective is to use as much of the existing equipment as possible to recoup maximum value from that initial investment. There has been considerable discussion regarding the viability of this equipment, particularly the HVAC units.

The VA has agreed to take responsibility for retro-commissioning any new existing equipment retained from previous projects. If it is determined this equipment

Page V-2 remains unwarrantable, the VA has agreed to take responsibility for its use and any maintenance issues that ensue.

9. The current Project was submitted as a Schematic Design on January 26, 2024.

This Submittal was not accepted as there was some miscommunication regarding the level of completion anticipated at this stage. Though no formal review was conducted, a review meeting was held on February 1, 2024, to offer informal feedback and direction from the VA. Minutes from this meeting are attached to this report as Appendix C1. Subsequently, the first of two Design Development packages (DD1) was submitted March 18, 2024. This submittal was reviewed, and comments generated by the VA in response to submittal DD1 are attached to this current report. Those comments were addressed within the context of this current submittal.

10. It is our understanding that the roof was replaced under the previous construction project. Water intrusion was observed during our site visit on 12/18/2023. The source could not be investigated at that time due to severe weather conditions. As this roof should still be under warranty from the recent installation, it is recommended that repair of these leaks be performed under warranty by the roofing company that performed that work. This warranty work should be independent of the current Project. There will be some new roof penetrations required as a component of this current project and those should be coordinated with the entity holding the roof warranty as well.

11. It has been observed that Plumbing work installed during the previous renovation is not code conforming and could require remediation. This will require selective demolition and repair of finishes already installed in the previous renovation, predominantly in the locker rooms and lounge. The VA expressed preference to retain all work in place and every effort will be made to do so. However, structural remediation will also require some removal and replacement of existing systems, and this can and will require bringing any system affected up to current codes.

12. The structural issues mentioned above primarily concern the floor on level 1 in the original 1951 building. In addition to the fact there has been some deterioration and the slab itself has been compromised, the 1951 design does not meet current live load code requirements and will not support the new laundry equipment. Nor is there provision for dynamic loads introduced by that equipment while in operation. Several alternative options for remediation presented in the schematic structural narrative were vetted. The only practical solution emerged, that defined as Option One in the Schematic Narrative. This solution WILL require some measure of removal and replacement of ceilings and HVAC ductwork installed during the most recent renovation.

13. Some deterioration of metal decking contained in the 1985 Addition was observed. It was learned this deterioration was likely the result of chemical storage and mixing in open vats below and is not likely to continue to be an issue

Page V-3 in the future as chemicals will no longer be mixed in open vats. The Structural remediation recommended calls for selective replacement of damaged deck sections only.

B. Life Safety:

1. The following items are in the process of being addressed:

a. An internal Life Safety Study has been performed. The findings are documented on Drawings LS101 & LS102 which are included in the

Drawings provided with this submittal.

b. A third-party Life Safety Review was conducted, and comments were received on July 3, 2024.

c. The Life Safety Study has confirmed that an additional exit and associated exterior stair leading from the East side is required to provide additional egress from the First Level. The drawings reflect the addition of a new exit door and exit stair from the West side of Area 105. In addition, a new egress door has been added to connect Room 102 with the egress pass through to Area 105.

2. Stairs: The existing exterior stairs appear to be adequate and will remain. An additional stair has been added to the west elevation outside Area 105.

C. Spaces Included in Design

1. Spatial definitions are as documented on Drawings LS101 & LS102 which are included in the Drawings provided with this submittal.

a. Areas within the Areas defined as Industrial, Accessory, Storage, &

Mechanical are included in the Scope of this renovation.

b. Spaces defined as Assembly, Locker Area, and Business are considered completed during the previous project and are not intended to be included in the scope of this renovation. However, Structural remediation in the Assembly and Locker Rooms will likely require some repair and replacement of work already in place. Business areas (and staff restrooms) will not be affected and will be considered excluded from the current Project. At the request of the VA, Light Storage Room B005 is also excluded from the project.

D. Scope of Demolition:

1. Demolition will include existing construction as needed to construct new work included in the Project design.

Page V-4

2. This Project WILL include large-scale repair or replacement of floor systems in the main laundry room particularly on the Soiled side which will require selective demolition.

3. Work included in the Renovation Area will not be required to be performed after hours.

4. A survey of the project area for asbestos (ACM) and lead-based paints (LBP) is excluded from the Scope of Work. It is assumed that all remediation work was completed by the previous project.

E. Scope of New Work:

1. Construction will include all areas included within the Scope of Work. Office areas, the Elevator, Light Storage Room B005, and the first-floor restrooms are specifically excluded.

2. Finishes will be replaced throughout the Project area, except for areas which received new finishes during the previous project that are suitable for re-use and can be protected from damage by construction operations.

3. Work will be coordinated with and designed to accommodate work required for structural, fire protection, plumbing, mechanical, and electrical systems included in the Project.

4. Doors, windows, and roof have been recently replaced as components of previous projects and are considered well within the span of their useful life. Thus, no work to the exterior of the of the building, except minor repair or Mechanical work is anticipated.

5. Owner Furnished or Installed Items:

a. Furniture, Furnishings, and Equipment

Laundry Machines and equipment are understood to be currently in the VA’s possession and are to be considered Owner furnished.

The installation of Laundry Equipment, including the Soiled Sort

Platform, associated stairs, overhead rail system and support structures are all to be considered future work and, though accommodated by the current design, F. Codes and Standards:

VI. Fire Protection

Page VI - 1

VI. Fire Protection

A. Design Requirements

1. The scope of the project is to provide adequate fire protection design to support the renovation of Laundry Building 45 at the VA Boston Healthcare

System – Brockton Campus.

2. The fire protection features of the facility including suppression and related components shall be a delegated designed. Design shall be incorporated under the direction of a registered fire protection engineer, a level 3 or higher NICET sprinkler technician certified in water-based sprinkler system layout, and a level 3 or higher NICET Fire Alarm Technician.

B. Survey of Existing Conditions:

1. The original design included a new sprinkler system. The sprinkler system installation is at approximately 80% completion throughout the building, with the first floor being complete and the majority of the basement level also complete. Email traffic indicates that when the project was abandoned, the system was filled with anti-freeze.

2. The original design included an upgraded fire alarm system, including the reuse of certain fire alarm components. The fire alarm system is at approximately 95% completion throughout the building, with the system substantially being installed at this time.

3. At the time the previous project was “terminated for convenience,” a temporary fire alarm system was installed.

C. Scope of Demolition:

1. All existing sprinkler system components are existing to remain. Main piping components including the backflow preventer, riser check valve, etc., are existing and shall be moved to a new location to provide a more maintainable system. Additionally, the new riser location will be served by a water line that penetrates the exterior wall adjacent, as opposed to the current location where the water line runs under a significant portion of building slab.

2. As the previous renovation included a mix of new and existing devices

(including a relocated FACP), all “new” fire alarm devices are existing to remain. Conduit and wiring for the new system will remain, and the wiring and components associated with the temporary system will be demolished.

Page VI - 2

D. Scope of New Work:

1. The contractor will complete the installation of the sprinkler system and make minor adjustments. The layout shall provide sprinkler coverage that, within the scope of work, is in full compliance with NFPA 13.

2. The contractor will make minor adjustments to the new fire alarm system

(substantially installed under a previous project) that within the scope of work, is in full compliance with NFPA 72.

E. Sprinkler System:

1. The following is the basis of design:

a. At the completion of this project, automatic wet pipe sprinkler protection will be provided for the entirety of building 45. A new system was substantially completed under a previous project, but there are some areas that require system installation or adjustment. The requirements indicated below will be incorporated into the design for all areas:

i. Sprinkler protection for the majority of the building shall be installed in accordance with NFPA 13 for ordinary hazard with some areas of light hazard.

a. Coverage per sprinkler head

• Light hazard is 225 ft2.

• Ordinary hazard is 130 ft2.

b. Design density

• Light hazard – 0.10 gpm per 1500 ft2

• Ordinary hazard – 0.20 gpm per 2500 ft2

ii. Maximum spacing per sprinkler shall not exceed limits specified in

NFPA 13.

iii. Pendent sprinkler heads shall be installed on return bends and all pendent heads shall be coordinated with other ceiling equipment or centered in the ceiling tiles.

2. Interior Piping and Components:

a. Sprinkler piping shall be steel and in accordance with NFPA 13. Piping 2” and smaller shall be sch. 40 and piping 2-1/2” and larger will be a minimum of sch. 10.

b. All sprinkler piping shall be supported from the building structure in accordance with NFPA 13.

Page VI - 3

3. Water Supply:

a. An updated water flow test is required and shall be conducted per

NFPA 291.

G. Fire Alarm System:

1. A new system was largely completed under a previous construction contract.

This project will provide minor adjustments to that system and complete the installation.

2. We have attempted to contact the fire protection maintenance contractor to determine if the existing FACP (located on the floor at our site visit) should be reinstalled or a new FACP provided. We have not received a return call.

The design currently indicates to provide a new EST4 fire alarm control panel.

3. Smoke detection will be provided at any fire alarm control panels. The fire alarm control panel will be located in a conditioned space. Notification appliance circuits will be Class B, signaling line circuits will be Class B, speaker/strobe circuits will be Class B, and Initiation Device Circuits will be

Class B.

4. Evacuation alarm activation will be via manual pull stations at building exits, smoke detectors and a waterflow switch.

5. Sprinkler system tamper switches and any duct smoke detectors (where required) will be monitored as supervisory conditions.

6. Speaker/strobes will be located throughout the building for occupant notification.

Sec on 4.5 – Legionella Mi ga on in VA Facili es of the VA Plumbing Design

Manual was updated in May of 2018. This update incorporated many changes aimed to be er define the requirements and the implementa on of Legionella mi ga on measures in VA facili es. Part of these changes require early coordina on between the plumbing design and each facility’s standing Water

Safety Commi ee. The Water Safety Commi ee was established by VHA

Direc ve 1061.

Legionella Design Approach:

To comply with the Plumbing Design Manual and VHA Direc ve 1061, the following features will be included in the project design:

1 Domes c Water Design Criteria

a. Piping will be routed to minimize fixture run-out lengths. These runouts shall not exceed the volume limits as described in sec on 4.4.2.b of the VA

Plumbing Design Manual. Runouts required to reconnect exis ng plumbing fixture branches located beyond the area of work might exceed the volume limita ons depending on their loca on and the exis ng pipe rou ng.

b. The hot water will be circulated and/or connect to the exis ng hot water circula on system.

c. Temperature monitoring device ports, for both hot and cold-water, will be located at the main riser, at the most remote fixture, and at the end of the hot water recircula on line prior to mixing.

d. All piping will be properly sized for all new and exis ng fixtures served within the scope of work area.

e. This project will include ASSE cer fied tempering valves in the project area.

These tempering valves will allow for elevated hot water supply temperatures. The point of use tempering valves will have a bypass installed to allow for thermal eradica on.

f. Domes c cold-water recircula on is cited as a possible Legionella mi ga on strategy in the VA Plumbing Design Manual. It is our intent not to recirculate cold water in this project.

2 This project is a partial renovation of the facility, therefore not all requirements of the VA Plumbing Design Manual and VHA Directive 1061 are implemented, as a number of these requirements are written for facility wide implementation. The following Legionella mitigation features have not been included:

a. Any means of supplemental water disinfec on

b. Any taps for temporary booster heaters for thermal eradica on

c. Domes c water mapping for the balance of the facility. Also not included is the upda ng of an exis ng mapping plan.

d. Installa on of a con nuous water quality monitoring system.

VIII. Mechanical

1. The mechanical scope of this project is to complete the HVAC systems based on the previously halted renovation project, including but not limited to equipment, ductwork, piping, and Siemens Design controls and control interface to the facility building automation system, for

Building 45, VISN 1 Laundry Facility. This design is required to comply with current Codes and DVA design standards, as indicated in the project SOW. The building is located at Veterans Affairs’ Medical

Center (VAMC), 940 Belmont Street, Brockton, MA. The design shall incorporate VA directives and guides, as required.

B. Existing Conditions:

1. Existing Conditions of partially renovated Building 45, VISN 1 Laundry

Facility.

a. Building 45 has been partially renovated to accept the stored material and equipment to process the laundry at the Brockton

VA. The construction was temporarily discontinued due to deficiencies in the flooring structure. A new design is required to be initiated to correct these deficiencies to ensure adequate support for the installed equipment.

b. All the original HVAC equipment and system demo has been completed.

c. Some of the HVAC equipment associated with the initial renovation project has been installed, including but not limited to heating-ventilating units, variable refrigerant fan coil units, unit heaters, piping, ductwork, insulation, grilles, and louvers.

Although this equipment has been installed, it has never had required start-up procedures and has sat idle for a period, extending beyond the specified warranty period. It is not recommended to operate this equipment without undergoing extensive mechanical system inspection and startup procedures.

d. The HVAC infrastructure, (i.e. refrigerant piping, HW piping, ductwork, insulation, grilles, diffusers, louvers, etc.), installed during the partial renovation exist at various levels of completion and may require reconfiguration in those areas requiring structural repair to avoid interference with that work.

Page VIII - 2

e. Control systems appear not to have been installed during the partial renovation.

C. Scope of Demolition:

1. All previously installed HVAC equipment will be reused whenever possible.

2. Existing HVAC ductwork, piping and appurtenances will selectively be removed, replaced and/or reconfigured as required to accommodate newly selected equipment.

3. In those areas requiring structural modifications, HVAC equipment and associated infrastructure will require selective and replacement to accommodate that work.

1. Heating System:

a. The occupied spaces will use a variable refrigerant flow (VRF) system(s) heat pump system for zone heating, as required. In those zones requiring simultaneous heating/cooling heat recovery

VRF condensers will be used. Storage spaces and other normally unoccupied spaces will use hot water unit heaters. Heating hot water will be produced through a steam-to hot water converter.

b. Ventilation air will be heated with hot water through a coil located in zoned heating & ventilating (HV) units.

2. Cooling System:

a. The occupied spaces will use a variable refrigerant flow system

(VRF) heat pump system for zone cooling, as required.

3. Ventilation and Exhaust Air System:

a. Make up air for process and required ventilation air will be introduced through HV units.

b. Building mass air balance will incorporate building/space exhaust fans to support the process equipment and building pressurization requirements. The air-change rate and +/- space pressurization will be maintained through constant air volume offset between required spaces.

4. Air Distribution:

a. Spaces requiring complete HVAC are conditioned by a combination of ducted VRF fan-coil units and non-ducted zone modules. Each FCU will be equipped with a filter/mixing box with

Page VIII - 3 disposable air filters, and DX coil. The system allows accurate zone temperature control.

E. HVAC Control System:

1. The building Automation Controls System will be a Siemens Design control system, consisting of a Direct Digital Control Panel (DDCP) and field mounted controllers, as required, which communicate over a local area network. A central workstation will be provided to allow for monitoring systems, set-point adjustments, trending, and alarming at the building level. Additionally, the control systems will be integrated with the facility building automation system.
