1. EXECUTIVE SUMMARY______________________________________________________

The Denver Federal Center (DFC) is located on the former Denver Ordnance Plant in Lakewood Colorado, and includes 44 Federal buildings of office, warehouse, lab and special use space totaling four million square feet of rental space on 623 acres. There are 28 different Federal agencies on site, making it the largest concentration of Federal agencies outside of Washington D.C. One of the major employers at the Denver Federal Center is the General Services Administration (GSA). The GSA is responsible for delivering much of the space requirements of Federal agencies, and provides national leadership, policy direction and standards in the areas of architecture, engineering, urban development, sustainable design, fine arts, historic preservation, construction services and project management.

1.a. DFC Building 67 / Bureau of Reclamation The GSA in conjunction with the Bureau of Reclamation has been tasked with reconfiguring and renovating space within Building 67 on the Denver Federal Center to support GSA and Department of the Interior (DOI) ongoing consolidation efforts to improve space utilization, optimize inventory, decrease reliance on leased space, and reduce the Government’s environmental footprint. The Bureau of Reclamation (Reclamation) is the primary tenant of Building 67, occupying approximately 90% of the 372,000 gross square foot office building. This high-rise concrete building was built in 1967, and is comprised of 14 floors and a penthouse. Building 67 currently houses approximately 1200 employees and consist of office space surrounding the elevator lobby and core area. The first level contains a full-service cafeteria, credit union, and a mail room supporting Reclamation. The consolidation of employees within Building 67 also includes the relocation of Reclamation personnel currently residing in other locations within the Denver Federal Center.

This consolidation project will provide space for approximately 1038 Bureau of Reclamation Employees within Building 67. Currently Reclamation occupies 275,107 usable square feet within the DFC’s Building 56 and Building 67. GSA has worked with Reclamation to reduce their program of requirement from 275,107 usable square feet down to 174,735 usable square feet, representing a 36% footprint reduction. While this effort is still taking place, and will be redefined during the design process, there is a requirement that a similar space reduction does take place.

The Bureau of Reclamation was established in 1902 and is best known for the dams, power plants, and canals it has constructed across the United States. Today, Reclamation is the largest wholesaler of water in the country. They bring water to more than 31 million people and provide one out of five Western farmers with irrigation water for 10 million acres of farmland. Reclamation is also the second largest producer of hydroelectric power in the United States. They have 53 power plants and provide more than 40 billion kilowatt hours generating nearly a billion dollars in power revenues and produce enough electricity to serve 3.5 million homes. The mission of the Bureau of Reclamation is to manage, develop, and protect water and related resources in an environmentally and economically sound manner in the interest of the American public.

The Bureau of Reclamation that is housed on the Denver Federal Center is currently made up of 7 primary directorates, that all perform a unique mission to the Bureau.

Therefore, each directorate has a different work style and unique space needs from one another.

Project costs, outlined herein, shall include design and construction services to complete the consolidation project. The project shall be provided in accordance with the GSA Contract and this Program of Requirements.

This Program of Requirements is organized to reflect the administrative role of the GSA.

The core, shell, and shared spaces are defined with the GSA Building section. The GSA Building is considered the “Base Building” which provides space and systems to support the “Tenant Spaces.” Whereas the tenants may have other shared (joint use) spaces, the GSA shared spaces are spaces that are used by any tenant in the building.

Public function independent of the operations of the tenants is not expected. If such a use was to be scheduled, proper security protocols would be followed to protect the interests of the tenants.

The requirements for each of the planned tenant spaces or directorates are provided in the dedicated sections herein:

Using GSA space calculation definitions, Building 67 will house Reclamation on approximately 9 floors at a utilization rate of 165 usable square feet (usf) per person without sacrificing high priority special spaces and shared spaces that assist in optimizing human performance, enhancing creativity while recruiting for the workforce of tomorrow.

The utilization rate of 165 usf per person will include support spaces such as conference areas, break rooms, phone booths, storage areas, huddle rooms, etc. The definitions for space calculation that have been agreed upon by both GSA and Reclamation are included within this POR. It is anticipated that Reclamation will occupy office space on floors 3-5 & 9-14. Currently floors 6 and 8 are occupied by other agencies and are not available for Reclamation occupancy.

As a part of the relocation and consolidation, incidental alterations and system upgrades to various systems, such as fire sprinkler, lighting, heating, ventilation, and air-conditioning will be necessary. There may be a need to upgrade to and within the building as part of this project as well. The selected contractor will determine this need when they complete their designs and can better estimate the power needs.

Project goals and objectives are:

Provide resilient, flexible, and capable work and meeting spaces for a 50-year old building;

Provide a clean, healthy workplace environment, free of harmful airborne contaminants and excessive noise, with access to quality light and ventilation;

Provide a workplace that allows occupants to adjust lighting, acoustic, and furnishing systems to meet personal and group comfort levels;

1.b. Design-Build Delivery GSA has selected Best Value Design-Build/Fixed Price with Award Fee as the delivery model for the DFC Building 67 / Reclamation Consolidation project for several key reasons. Chief among these are maximizing the project’s design and construction value related to prioritized needs, expectations, and goals for both GSA and Reclamation within the context of the known challenges, constraints (including price), and project risks. This model delivery approach requires the GSA to list the specific quality/quantity requirements (programmatic as well as general project expectations) throughout the GSA Contract and this Program of Requirements. Checklists are provided by GSA to document performance and compliance of the Offeror.

Design Stage services and Construction Stage work are to be performed by the Design-Build ( DB) Contractor. Design Stage services include providing Design Concept and Design Development Phase services. The scope of services for the Design Stage will require at a minimum: Professional architectural, engineering, interior design, and related consulting services for concept design documents, design development documents, and construction documents.

Construction Stage work includes preparing construction documents, providing all materials, and labor to perform the construction in conformance with the project requirements. The scope of services for the Construction Stage will require at a minimum:

preparation of construction documents, specifications, cost estimates, computer-aided design and drafting (CADD), B u i l d i n g I n f o r m a t i o n M o d e l i n g ( B I M ) , Critical Path Method (CPM) scheduling, scope management, value engineering, maintaining construction records, utilizing an electronic project management system in order to manage project documents, monitoring construction costs, commissioning, and construction.

The Design-Build contractor shall have a full understanding of the project, its contract documents, and the principles of Federal construction contracting and contract administration. Most importantly, the Design-Build contractor shall have complete responsibility for design and construction of the facility, including timely delivery within the project budget.

1.c. Design Excellence Program To ensure a high standard of excellence for the American public, GSA engages the best private sector architects and engineers to design, modernize existing and construct new Federal buildings through its internationally renowned Design Excellence Program.

The Design Excellence Program is the center for GSA's advocacy of quality in the federal built environment. It establishes nationwide policies and procedures for selecting the finest and most appropriate architects and integrated design teams for GSA commissions. The program also implements rigorous assessment processes to ensure enduring value in that work. Operating under the Design Excellence umbrella, the First Impressions, Interior Design, Lease Construction, Urban Development, and Sustainability initiatives review projects for superior performance in their respective disciplines. Equally notable, the Design Excellence Program manages national peers, distinguished private-sector design professionals appointed by the Commissioner of the Public Buildings Service to advise procurement and to critique concept designs under development. Exhibits and other events, publications, and videos underwritten by the program document the Design Excellence process as well as its most significant results: holistic environments that add contemporary form and meaning to America's rich legacy of public architecture.

2. GSA BUILDING_____________________________________________________________

The General Services Administration (GSA) is overseeing the design and construction of a consolidation project for Reclamation located within Building 67 on the Denver Federal Center campus.

Any conflicts or ambiguities within or among the referenced standards and criteria documents, or any deviations from requirements contained in the standards and criteria documents, must be reported to the GSA in writing, for determination as to applicability.

2.a.ii. Limits of Scope The limit of this scope is approximately 9 floors, which shall include elevator lobbies, work areas, conference rooms, kitchenettes, and storage rooms. The scope does not include restrooms, main public lobbies located on the first floor and lobby levels, nor does it include the larger conference rooms and cafeterias on these levels.

It is assumed that all furniture, fixtures and equipment (FFE) will not be included in the Design-Builder’s price (i.e. it will be provided by the tenant) unless noted otherwise. Furniture shall mean any movable tables, chairs, bookcases, shelves or any other office or lobby related movable items.

Equipment shall mean computers, printers, laboratory equipment, or other items mobile and specific to each tenant.

The Design-Builder is otherwise expected to provide all fees, materials, labor to allow each tenant to move into the space and connect their own FF&E as described herein.

It shall be the responsibility of the Design-Builder to review, understand and provide the required utilities and connections to allow all tenants to connect and use their furniture and equipment following turnover of the space.

2.a.iii. Sustainability It is expected that this building will incorporate as many elements of sustainability and current sustainable technologies as possible to have a http://www.wbdg.org/sustainableEO) minimum negative impact on the earth. Passive design should be first. For example, attention should be given in maximizing daylight and natural ventilation. Proposed systems should be modeled and rigorously evaluated for first costs, life cycle costs, and carbon savings with an emphasis on reducing consumption – consumption of energy and consumption of replaceable parts and components.

2.a.iv. Site Location and Access The site is located in western Lakewood on the Denver Federal Center property and is east of Gate 4 off of 4th Avenue from Union Boulevard, directly adjacent to 7th Street on the Denver Federal Center (DFC).

The DFC site can be accessed from major roadways of 6th Avenue, Kipling Street or Union Boulevard.

Although there is no direct access to 6 th Avenue, Kipling Street has access to the site from Gate 2 and Gate 1. Gate 1 is specified for visitors, and has guard stations for both badged and un-badged visitors and employees. Gate 2 is to be used primarily for deliveries, and all delivery vehicles will be searched prior to being provided access onto the Federal Center site. Gate 4 from Union Boulevard on the west is also a visitor designated entrance.

All members of the design-build team, including all subcontractors shall comply with the required badging procedures for site access, which will be coordinated through GSA’s Contracting Officer. All visitors must present a valid government issued ID, may be subject to random vehicle searches.

2.b. Program Summary

2.b.i Space Requirements The following strategies shall be utilized during the design development:

• Demolition of existing light gauge-framed gypsum board walls, in addition to the removal of carpet, acoustic ceilings, and lighting. Other miscellaneous demolition is also required.

• Conference spaces, huddle rooms, phone booths, reception areas and enclosed office spaces will be utilized to create a buffer zone between the building core and the general workplace environment.

• The existing numbers of conference room spaces are to be maintained at a minimum, but preferably increased throughout the space (estimated numbers required will be provided during the developed during the design phase), will be shared conference rooms distributed evenly on each floor as allowed by space availability, and attached to the building core.

• The perimeter zone will be kept open to preserve maintenance access to building systems and to optimize natural light and views across the workplace environment. No walls are allowed to connect to the building perimeter.

• Approximately 111 new enclosed offices will be required. This can be achieved by hard walls or preferably demountable walls.

• Controlled security access off the elevator lobby of each floor of the building occupied by Reclamation.

• All lobby level and 1st floor conference rooms will need to be included within the utilization rate, however upgrades to these rooms are not included in this project.

• Create a sense of branding within the Reclamation workspace that highlights the mission of the Bureau of Reclamation in addition to motivating its employees in representing the agency’s objectives.

2.b.ii. Interior The interior environment shall be designed to enhance occupant comfort, productivity, creativity, and general health and well-being. The interior will be an environment that fosters the mission of each directorate, as well as a sense of community, to reflect 21st century workplace strategies. Materials, colors and textures shall create an enjoyable, open yet cozy well defined user experience for both everyday users and visitors to the building.

The interior environment should reflect that there are different directorates, but the design should be complementary. This may tie to a larger way-finding design for the building, so that it is approached cohesively.

2.b.iii. Restrooms Restrooms repairs and alterations are not included within this project unless adjusted building floor occupancy requires additional facilities, in accordance with the latest International Plumbing Code.

2.b.iv. Office Areas The employee office areas should be designed based on the function of its occupants. Since each Directorate has a distinctly different function, the employee office areas from floor-to-floor, and within directorates, may be somewhat different. A more open floor concept is desirable to improve the HVAC effectiveness and to increase the light that moves toward the center of the building, while still meeting the working need of each directorate.

It is also necessary to centralize the location of personnel within a directorate to consolidated floors as much as possible, with the exception of a few offices such as the Civil Rights Office. These exceptions will be provided prior to floor design.

Some directorates have indicated a preference for open, collaborative workspaces, while others anticipate performing more effectively in a concentrative workspace where collaboration takes place in conference rooms.

Consideration should be given to segregating high traffic areas and visual distractions from employee workspaces.

Workspaces for some directorates will require more storage elements within and adjacent to the workstations to maximize productivity.

“Hoteling” workstations are envisioned for some directorates.

Workstations will include at least two power outlets and two data drops per workspace for efficient working conditions.

Open office workstation areas will be designed to be flexible and expandable, and will have ample daylight and at minimum, visual connections to the outdoors. Lighting will utilize daylight harvesting and will provide for ample light with an indirect component to the fixtures. The lighting layout will allow for reconfiguration of and flexibility with the open office workstations. Acoustic elements will be artfully provided to eliminate excess sound reverberation which can become a distraction and a deterrent in open office situations.

In addition to acoustic damping elements and space layout to separate high noise areas from concentrative workspace, an effective masking (white noise) system is encouraged to be designed as part of the space.

The use of color for identification and way-finding is encouraged, as well as the use of materials and textures to aid in the comfort, productivity, creativity, and general health and well-being of the occupants.

2.b.v. Kitchenettes Kitchenettes consisting of built in cabinets and countertops, two with sinks, are currently located on each floor. The program requires that as many as two new kitchenettes be installed (all with sinks and garbage disposals) on each floor that will be occupied by Reclamation as part of this project. All cabinets and countertops should be removed and replaced with cabinets and countertops that meet requirements in the new break rooms at each floor. Refrigerators should be provided at each location. The kitchenettes should be located where most efficient within the design and construction.

2.b.vi. Phone Booths

Phone booths will be required for individual space with privacy for short term use.

These spaces should be available on all floors that will be occupied by Reclamation as part of this project. These private “acoustically sound” rooms shall be approximately 36 square feet, and be fit out with mechanical, electrical, data, and lighting. In addition, a desk height counter is also anticipated. It is estimated that 36 phone booths will be needed (four per floor).

2.b.vii. Conference Rooms It is important to incorporate the use of more conference rooms into the workplace for both formal and informal meetings. The conference rooms should have an atmosphere of collaboration, productivity, and engagement A mixture of conference room sizes should be provided on each floor based on the agency’s requirements to include:

• Huddle Spaces (2-3 people) – approximately 18 (2 per floor)

• Small Conference Rooms (4-6 people) – approximately 18 (2 per floor)

• Medium Conference Rooms (8-12 people) – approximately 19 (one adjacent to each directorate’s office with the remaining distributed amongst the floors.)

• Large Conference Rooms (13-25 people) – approximately 12 (distributed among the floors with at least one per floor.)

2.c System Narratives 2.c.i. Site Systems 2.c.i.1. Utilities

The DB Constructor shall provide a comprehensive utility survey to include, but not limited to, electrical, sewer, water, telephone, fiber optic, and gas in an effort to understand and assess the utilities needed and affected by the project including:

• The condition of the systems conformance to PBS-P100.

• Capacity (flow, pressure, etc) sufficient to meet the needs of the building and not diminish service to others on the line.

• Connection requirements

Other utilities services (gas, electric, communications, etc.) should be coordinated with the respective franchise owner and the design team. Modifications to existing utility facilities that are required based on the design shall be provided by the DB Constructor prior to performing work. Shut downs, if necessary, must be coordinated with GSA.

2.c.i.2. Power

The site electrical system is fed from a medium voltage loop system on the GSA campus. As-builts will be provided as an attachment to this solicitation.

2.c.ii. Architectural Systems 2.c.ii.1. Windows Exterior window replacement will not be a component of this project.

2.c.ii.2. Partitions

Interior walls and partitions shall meet code requirements and meet Reclamation’s needs. Partitions in high use areas and those walls separating the elevator core / joint use space from Reclamation’s workspace shall be of a more durable construction and finish than those in the typical office space. Interior partitions shall be metal frames gypsum board partitions and follow acoustical best practice, unless stated otherwise. Blocking shall be provided at all office partitions to accommodate planned and future wall mounted equipment, casework, shelving, other items requiring anchorage.

Any additional costs for demountable walls for enclosed office spaces, huddle spaces, phone booths, and all sizes of conference room spaces shall be priced separately as an option (Option: Demountable Walls).

The demountable walls shall have approximately the same sound attenuation as drywall without insulation (>30 STC) and be of sturdy construction such that equipment and furniture can be mounted to the surfaces. Demountable walls shall be constructed with universal frames for interchangeability and flexibility.

2.c.ii.3. Ceilings It is anticipated that the existing structural waffle slab will continue to be exposed at all contiguous open workplace environments, as it is under current conditions. In this scenario, there is a need for some acoustical treatments, i.e. sound clouds and white noise which will need to be provided to mitigate sound bounce and transmission. Offices, conference rooms, kitchenettes, and copy/print rooms are expected to have acoustical ceilings with an extension to the grid (if applicable) or new grid and all new ceiling tiles. Noise masking at interfaces between dropped ceilings and areas with the exposed waffle slab is necessary.

2.c.ii.4. Finishes

Building 67 generally has three space types – office, restroom, and utility

– and within each space type the finishes are similar throughout the building. The floors have been remodeled over the years and though the materials are similar throughout the building, ages of the finishes and layout varies. It is expected that the DB will demo and replace all finishes in areas included in the scope of this project.

All construction and materials are required to be institutional quality, consistent with an attractive finish that is easy to maintain. The lifetime of the material and the ability for materials to be replaced should be taken into consideration so that updates in high traffic or high abuse areas can be more easily achieved. All interior finishes (including adhesives and sealants) are assumed to be low in volatile organic compounds (VOC’s), consistent with the sustainable design goals.

Office Standard - Office standard finishes include the following that will be determined during design:

• Walls: Paint – color and finish to be determined.

• Floors: New commercial carpet tile; new rubber base. Option for raised floors.

• Ceilings: New acoustic lay-in tile NRC 0.70 or similar and grid.

Sound clouds shall be constructed of appropriate acoustic materials

• Doors: New flush wood doors and frames (except at stairways).

Hollow metal doors and frames at stairways should be repainted.

Option for sliding barn doors shall be included with the demountable wall system.

• Window treatment: All existing and new interior and exterior locations will need new window treatments.

Utility Standard Finishes - Utility standard finishes include the following:

• Walls: Paint with a semi-gloss finish – color to be determined.

• Floors: Concrete, new sealed or resilient flooring, new rubber base

• Ceilings: Exposed to structure and utilities, painted.

Any gypsum surface exceeding 15 lineal feet or 100 square feet shall have a level 5 finish.

2.c.ii.5. Equipment

The DB Constructor shall schedule and coordinate all equipment with respect to responsibilities to furnish, rough-in, placement, connection, and testing.

2.c.ii.6. Acoustics GSA P-100 Acoustical Requirements

2.c.iii. Mechanical and Plumbing Systems All information provided within this section shall be verified by the DB contractor in relation to existing conditions and recommendations.

Heating is provided by steam boilers located in a different building; cooling is provided by centrifugal chillers. The first floor and lobby level are serviced by air handling units with chilled water and steam coils, as well as perimeter steam baseboard heaters. Floors 3-14 are serviced by central air distribution fans with chilled water and steam coils. On the perimeter, the air is distributed through induction units with variable temperature coils. On the interior, hot deck and cool deck air is distributed to mixing boxes. There is also an auxiliary condenser water riser loop providing heat rejection for various heat pumps throughout the building. While some of the major equipment components are recommended to be repaired (Building 67 – Bureau of Reclamation Space Consolidation, Building System Study; dated February 5, 2016 (BSS)) the air distribution system within the building seems to receive the largest complaints. The DB will need to extend ductwork from the interior soffit out into the new tenant space as required to provide better thermal comfort. In addition, new grilles, registers, and diffusers are required for those areas extended. In addition, the existing HVAC system shall be cleaned.

2.c.iii.1. Air Distribution – Induction Unit System

The induction unit system serves the perimeter zones of floors 3-14, divided into two halves, floors 3-8 and 9-14. Each of those systems is further divided into four air streams, corresponding to the four cardinal building exposures. The air is then distributed to induction units lining the perimeter of each floor.

The air from the supply fans is accelerated through nozzles in the units to induce additional air movement from the air space. That air is then directed through mixed temperature water coil to maintain an average space temperature set-point of all floors of each exposure.

The existing perimeter induction units as constructed provide limitations on how the adjacent space can be utilized in the space plan. Currently, a walkway is provided to allow for circulation to workplaces, and this space allows for maintenance to occur on these systems at any moment without the need to move equipment or furnishings.

The DB contractor shall add additional control valves to the induction units to increase comfort control capabilities. In addition, induction units shall be cleaned after construction has been completed on the floor and prior to occupancy of that floor.

2.c.iii.2. Air Distribution – Fans/Coils – Floors 3-8

The air conditioning and distribution for the induction unit system serving floors 3-8 is in the first floor mechanical room. 80,000 CFM of outside air is brought through the building through the intake louvers on the first floor. Steam pre-heat coil PC-1, along with face-and-bypass dampers temper air when necessitated by low outside temperatures. Outside air and return air are mixed before being divided into two airstreams serving both this system through SF-2 and the dual deck system through SF-1 (see floors 3-8 dual deck system). The total design outside air percentage is for the two systems combined is 77%. After the division, the air is run through cooling coil SC-2, and then onto SF-s. SF-2 is a 44,000CFM fan driven by a 100hp motor powered by a VFD. The VFD modulates to maintain a building static pressure set-point. After the fan, the airstream is divided into four, one for each cardinal building exposure. Then each of those airstreams is heated by reheat coils RC- 2, 3, 4, 5 before being distributed to the induction units on each floor.

Those coils are controlled to a discharge air temperature set- point, reset based on outside air temperature.

The DB contractor shall replace the steam coils and associated piping as part of this project. In addition, ductwork distribution to support any new proposed enclosed spaces within the floor plate would need to be re-routed and/or introduced from the primary duct to deliver air to these new spaces. All ductwork shall be cleaned after construction of the floor and

2.c.iii.3. Air Distribution – Fans/Coils – Floors 9-14

The air conditioning and distribution for the induction unit system serving floors 9-14 is in the penthouse mechanical room. 44,000 CFM of outside air is brought into the building through sidewall intake louvers in the penthouse. Steam pre-heat coil PC-3, along with face-and-bypass dampers temper air when necessitated by low outside air temperatures.

Outside air and return air are mixed before being filtered and enter SF-4.

The design outside air percentage is 100%. The air is run through cooling coil SC-4, and then onto SF-4. SF-4 is a 44,000 CFM fan driven by a 100hp motor powered by a VFD. The VFD modulates to maintain a building static pressure set-point. After the fan, the airstream is divided into four, one for each cardinal building exposure. Then each of those airstreams is heated by reheat coils RC-7, 8,9,10 before being distributed to the induction units on each floor. These coils are controlled to a discharge air temperature set-point, reset based on outside air temperature.

The DB contractor shall replace the steam coils and associated piping as part of this project. In addition, ductwork distribution to support any new proposed enclosed spaces within the floor plate would need to be re-routed and/or introduced from the primary duct to deliver air to these new spaces. All ductwork shall be cleaned after construction of the floor and

2.c.iii.4. Air Distribution – Mixed Temperature Water Loop

The mixed temperature water loops serve the coils in the induction units.

There are four individual loops, one corresponding to each cardinal building exposure. Each loop is circulated by a pump (east and west pumps are 15 hp and north and south pumps are 7.5hp). Control valves allow chilled water to be mixed into each circulating loop to decrease the temperature as needed. The temperature set-point of each loop is determined based on space temperature sensors on each exposure of each floor that are averaged.

The DB contractor shall install new control valves on the induction units and change the sequence of operations to increase comfort control. In addition, ductwork distribution to support any new proposed enclosed spaces within the floor plate would need to be re-routed and/or introduced from the primary duct to deliver air to these new spaces. All ductwork shall be cleaned after construction of the floor and prior to occupancy of that floor.

2.c.iii.5. Air Distribution – Dual Deck System – Floors 3-8

The dual deck system serves interior zones of floors 3-14, divided into two halves, floors 3-8 and 9-14. Once conditioned in the first floor and penthouse mechanical rooms, respectively, a hot deck duct riser of 80 degrees and a cold deck riser of 55 degrees run up and down the building respectively. The two airstreams are ducted to several mixing boxes on each floor where the air is combined in proportion to maintain a space temperature set-point controlled by a thermostat.

The air conditioning and distribution for the dual deck system serving floors 3-8 is located in the first floor mechanical room. 80,000 CFM of outside air is brought through the building through the intake louvers on the first floor. Steam pre-heat coil PC-1, along with face-and-bypass dampers temper air when necessitated by low outside temperatures.

Outside air and return air are mixed before being divided into two airstreams serving both this system through SF-1 and the induction unit system through SF-2 (see floors 3-8 induction unit system). The total design outside air percentage is for the two systems combined is 77%.

SF-1 is a 70,000CFM fan driven by a 100hp motor powered by a VFD.

The VFD modulates to maintain a building static pressure set-point. The airstream is divided in two. The hot deck is heated by steam coil RC-1, and the cold deck is cooled by cooling coil SC-1, each to respective discharge air temperature set-points, and then distributed to each floor.

The DB contractor shall replace the steam coils as part of this project and extend the floor-by-floor ductwork to increase air distribution effectiveness and duct to enclosed spaces as required. In addition, ductwork distribution to support any new proposed enclosed spaces within the floor plate would need to be re-routed and/or introduced from the primary duct to deliver air to these new spaces. All ductwork shall be cleaned after construction of the floor and prior to occupancy of that floor.

2.c.iii.6. Air Distribution – Dual Deck System – Floors 9-14

The air conditioning and distribution for the dual deck system serving floors 9-14 is in the penthouse mechanical room. 15,000 CFM of outside air is brought into the building through sidewall intake louvers in the penthouse. Steam pre-heat coil PC-2, along with face-and-bypass dampers temper air when necessitated by low outside air temperatures.

Outside air and return air are mixed before being filtered and enter SF-3.

The design outside air percentage is 21%. SF-3 is a 72,000 CFM fan driven by a 100hp motor powered by a VFD. The VFD modulates to maintain a building static pressure set-point. The airstream is then divided in two. The hot deck is heated by steam coil RC-6, and the cold deck is cooled by cooling coil SC-3, each to respective discharge air temperature set-points, and then distributed to each floor.

The DB contractor shall replace the steam coils as part of this project and extend the floor-by-floor ductwork to increase air distribution effectiveness and duct to enclosed spaces as required. All ductwork shall be cleaned after construction of the floor and prior to occupancy of that floor.

2.c.iii.7. Controls All information provided within this section shall be verified by the DB contractor in relation to existing conditions and recommendations.

A DCC system was added to the building in 1992. However, most actuators are still pneumatic. Some parts of the systems have been updated more recently, however the entire system should be gone through and adjusted as part of this project.

The DB contractor shall install new additional control valves for the induction units and change the sequence of operations to increase comfort control. As part of the installation of the new control valves, the system should be rebalanced.

2.c.iii.8. Domestic Waste and Vent Piping contractor in relation to existing conditions and recommendations.

Domestic waste and vent piping serves restrooms throughout the building, break rooms, and the kitchen. Demolish existing piping from kitchenettes back to mains. Install new waste and vent piping for new kitchens. It is anticipated that this new waste riser will need to be added in a new plumbing chase at the building core. The waste piping should be large enough to allow for additional future capacity.

2.c.iii.9. Domestic Hot Water and Cold Water Piping contractor in relation to existing conditions and recommendations.

The domestic hot water and cold water piping serves restrooms throughout the building, break rooms, and the kitchen. Break rooms only exist on a few floors, and the Kitchen exists on the first floor only.

Demolish existing kitchen fixtures and associated piping back to mains.

Provide new hot and cold water piping and fixtures to all new break room kitchenettes areas on each floor.

2.c.iv. Accessibility New designs for each floor will ensure layouts meet accessibility requirements.

Deficiencies in the restrooms will be addressed under the separate, ongoing, restroom project.
