H. Phasing:

Building 1, five (5) stories high with an attic, was constructed in

1933 as the main hospital on the Veterans Administration Bay Pines

Medical Campus. A stucco exterior finish is applied over 12” thick masonry walls supported on a concrete frame structure. The existing concrete structure is composed of columns and a beam with one-way joist floor system. An existing wood framed roof and attic occupy the space above the concrete framed typical floors below. The crawl space has a concrete structure. Both attic and crawl space contain building HVAC, Plumbing, Electrical, Voice/ Data and Fire Protection systems that are general in nature to the overall building systems.

In 1983 the current main hospital, Building 100, was built as a replacement hospital for Building 1 which was converted in a total rehabilitation of both exterior and interior into a Psychiatric

Hospital. All finish materials were removed exposing the masonry walls and concrete frame. During this rehabilitation a food service function was installed on the 1st floor which today operates as the Canteen for the entire Medical Campus. With the construction of the currently proposed Mental Health Addition as an addition to Building 100, the interior partitions and supporting MEP utilities will once again be totally renovated to create a Business Occupancy, Primary Care

Outpatient facility from the current Institutional, Hospital occupancy.

Existing interior partitions finishes, and ceilings will again be removed exposing the masonry walls and the exposed concrete structure.

During this total interior rehabilitation effort, however, portions of the building will remain open with medical campus functions operating during the construction. It is not envisioned that any clinical function will remain in Building 1. All those existing clinical functions relocated to the new Mental Health Addition. The critical occupancy that will require continued use is the food service function

B1 PACT Primary Care Renovations

01 00 00 -9 of the canteen. The use of interior space will result in various undetermined Medical Campus functions using floor space during construction on other floors of Building 1. This will result in a phased construction schedule and duplication of new and existing utility infrastructure to maintain current, remaining occupancies and newly installed occupancies.

The mixture of construction activities and existing/ new occupancy of the building is a critical issue of any phased construction.

Authorities having jurisdiction require separate occupancy inspections to ensure that life safety requirements are met in any phased construction project. Means of egress, environmental considerations regarding noise and dust, and contamination of the quality of air environment during any hazardous material removal are concerns during construction and final occupancy simultaneous use of the building. With the complications of a phased construction schedule of the building is the further heightening of these dangers by adding an Assembly Use, Restaurant/ Kitchen activity combination to the occupancy considerations. Means of egress concerns are heightened and the freedom from airborne dust during construction, especially involving possible hazardous materials becomes an especially important criterion. It becomes an essential element to the cost of general conditions to any

Construction Contract.

The cost of the phased construction needs to address the duplication of

MEP systems and the commissioning of the operating system. Not only are the systems redundant between new and existing but the commissioning effort portion of the work to ensure those systems are operating per designed criteria is also a redundant effort not only for the various phases but also for the total, final building operating system.

The proposed construction phases of Building 1 are the following:

Phase 1

It is proposed to start interior alterations, Phase 1, on the second

(2nd), third (3rd), fourth (4th) and fifth (5th) floors of Building 1 while also completing general building scope of work to the utility infrastructure on the first (1st) floor, attic, and crawl space. To

B1 PACT Primary Care Renovations

01 00 00 -10 maintain existing use of the building on the first (1st) floor there needs to be juxtaposed next to each other redundant systems of existing and new. During the construction phase on the 2nd,3rd, 4th, and 5th floors while the 1st floor is occupied will require a separation between public access and construction access.

The proposed phasing and continued use of the building during construction will involve periodic shutdowns and disruption in utility service which can be scheduled during off hours, but this comes with an additional price.

Phase 2

Exterior work to provide a new accessible covered entry, drive improvements, parking lots, and landscaping, and work covered in the

Civil Engineering drawings for exterior improvements.

Phasing this large-scale renovation project further will not be required since the design intent is for the Construction Manager to have access to floor 2 through 5 at the same time, and the construction will be handled in one phase. Based on analysis of the existing systems and proposed new floor plan layouts, the following additional work is required beyond the construction effort involved if this building were completely shut-down during interior alterations.

HVAC

Chilled Water Lines

Sections of the main chilled water distribution in the crawl space, 1st floor and two main piping risers will have to be replaced.

In order to keep the 1st floor of Building 1 and Buildings 22 and 23 operational, piping work will be needed as shown on the “pre-demolition” plans. Temporary cooling to the four air handlers on the 1st floor would be required (approx. 104 tons), along with cooling for

Building 22 and 23 (approx. 270 tons). The intent is to continue to utilize chilled water from the central chilled water plant. This can be accomplished by installing new main piping and hot-tapping into the existing 12ӯ either with a new 10ӯ service to replace the 8ӯ or with an additional 6ӯ or 8ӯ to supplement the existing 8ӯ piping. The

B1 PACT Primary Care Renovations

01 00 00 -11 existing chilled water pumps will be used to serve the floors and buildings still operating during Phase I of the renovation. A temporary air-cooled chiller with its own pumping system should be considered during any temporary shut down and high-risk procedure (i.e.

hot-tapping) to ensure minimal or no downtime of the existing cooling system.

Once the new piping risers are in place and energized, the existing four air handlers on the 1st floor (i.e. 104 tons) and the cooling systems in Building 22 and 23 (i.e. 270 tons) will be switched over.

Outside Air Intake

One of the air handlers on the 1st floor has its outside air (OA) provided through the two main an existing OA duct riser. Temporary duct connecting temporary supply fans in the attic to the existing risers will be required. Note that the existing supply air fans are in conflict with the proposed location of the new mechanical equipment in the attic, requiring either the fans, or the usage of rental fans.

Once the new OA riser is installed, the temporary duct connection can be disconnected and the floor space used on floors 2, 3, 4 and 5 can be recaptured.

Exhaust Air

The exhaust air (EA) is handled in a similar manner, although there are four risers in addition to the two main risers in the chases adjacent to the stacked mechanical rooms. These additional four risers serve the 1st and 2nd floor and will have to be maintained operational throughout the renovation. Temporary fans may be required during the renovation, if the existing ones cannot be slowed down to exhaust the reduced flow rate of just the 1st floor.

Hot Water Heating Pumps/ Steam Converter

The existing steam-to-hot water converter produces heating hot water for both Building 1 and Building 22. Before any demolition is done, a temporary steam-to-hot-water converter shall be installed and energized, as shown on the “pre-demolition” plans.

B1 PACT Primary Care Renovations

01 00 00 -12

A pre-design test of all air handlers, exhaust fans, outside air fans, pumps in Building 1, as well as chilled water and heating hot water flows to buildings 22 and 23 is needed and should be included in this project’s estimated cost. This work shall be sub-contracted with a NEBB or AABC certified agency.

Electrical Distribution

Electrical Power Supply

To proceed with the proposed sequence of construction, it is proposed to furnish temporary power distribution via a (approximately 750 kva) pad mounted transformer and associated weatherproof distribution equipment located outside at the East side of Building 1 adjacent to existing manhole 216 during the replacement of the existing unit substation. This temporary transformer and distribution equipment shall have the capacity for furnishing power to the first, second, third floor, connecting corridors and attic equipment. All temporary feeder conductors shall be protected from damage and may be run exposed to the appropriate panel boards or distribution equipment in the 1st floor. The temporary transformer and associated distribution equipment shall be temporarily served by one of the existing campus looped 12.47kV normal power feeder via new splice tap at existing manhole 216.

After the new permanent unit substation has been installed, tested and commissioned, the temporary transformer and associated weatherproof distribution equipment shall be disconnected and removed. The new electrical distribution equipment shall be connected directly to the permanent distribution equipment.

Emergency Generator

Also, at this time, the existing standby generator will be replaced under Bid Option No. 1. A temporary (approximately 800kw) standby generator shall be furnish and install outside the building with sufficient fuel capacity for 96 hours at full load condition. The temporary generator shall serve all Equipment Branch and Life Safety loads for the 1st floor and common areas, emergency load for Building 22 and Building 23, that is presently served from Building 1 emergency generator. This generator can be located outside adjacent to the

B1 PACT Primary Care Renovations

01 00 00 -13 loading dock; thereby allowing the running of the generator feeder cables into the essential electrical room for connection to existing panels EGDP (Building 1) and EMDP (Building 22).

Once the permanent standby generator is installed, tested and commissioned, the temporary generator may be disconnected and removed.

Additional Work Considerations

In addition to the extra work described above, the following existing systems and/or utilities during Building No1 renovation will be impacted and further temporary work and equipment may be required.

1- The existing fire pump will be replaced. (Life Safety Issue).

2- The existing fire alarm system will be replaced. (Life Safety Issue).

3- Existing security and telephone systems will be replaced.

Additional Concerns

1- Hazards associated with a designated construction zone located above and around the first floor Canteen. This includes access (exterior pathways) to the Canteen, dust infiltration, noise from construction activities, possible exposure to hazardous materials removed during construction, and associated insurance implications; for both contractor and VA. Additionally, there is the possibility that due to second floor construction, access to the first floor may be necessary for under second floor work. (First floor plenum space).

2- The possible disruption or increased complications in food and supplies delivery due to construction activities in removal of existing electrical substation, generator set, underground generator fuel tank and underground transformer oil containment tank; installation of new underground generator fuel tank, installation of new generator and electrical unit substation and the possible re-routing of new underground high voltage (12,470 volts) feeders.

3- The hazards and operational adjustments required of furnishing temporary utilities or systems required for the proper operation of the

Canteen; i.e. electric power, emergency electric power (temporary standby generator), fire pump and associated fire protection piping

B1 PACT Primary Care Renovations

01 00 00 -14 system, fire alarm system, chilled water and associated equipment

(pumps), steam, domestic water, LP gas, ventilation equipment, security and telephone systems.

Plumbing

As part of Phase 1, the Domestic Water Booster Pump System located on the First Floor of Area B will be replaced. The Domestic Water Heating

System will be re-piped. Interruption of the Domestic Water Service will be required to make the tie-ins of the new systems. Roof drainage and rainwater leaders will be rerouted on various floors during the renovation processes. The sanitary waste and vent systems for Floors 3, 4, and 5 will be collected in the ceiling space of the Floor 2, tied together and drop through Floors 1 and 2 adjacent to column structures or in chases down to the crawl space. The sanitary waste and vent systems will be redistributed for the renovation of Floors 2 – 5 requiring ceiling access in Floors 1 – 4 for collection of the sanitary waste piping from the new plumbing fixtures on the floors above.

The Floor 1 domestic water systems are fed up from the crawl space below with limited domestic water piping above Floor 1 ceiling. A 4” cold water, 2 1/2” hot water, and 1 1/4” hot water return piping rises in a chase just west the main elevator banks up from the crawl space to

Floor 2. The domestic water systems are then distributed above the ceiling down to Floor 2 fixtures up to risers serving Patient Floors 3, 4, 5.

Domestic Water

Under Phase 1, Floor 1 would remain in operation while renovating

Floors 2 through 5. The domestic water systems in the ceiling space of

Floor 2 would remain in operation including the risers up through Floor
