PREFACE

I. PREFACE

a. Background Info

Building 137 is a six story former residential structure at the U.S. Army Garrison, For t Hamilton, Brooklyn, N.Y. It is par tially occupied and in use for administrative and community service occupancies by military personnel and Depar tment of Defense civilians. Building 137 has repor ted structural deficiencies, has exceeded its useful life expectancy and is slated for demolition.

The Garrison intends the tenants of Building 137 to be relocated into Buildings 114, 218 and 125 which are either currently, par tially unoccupied (B114), or about to be vacated (B218 & 125).

The U.S. Army Corps of Engineers commissioned QPK Design to facilitate a planning charrette to:

• Create the spatial program of the impacted tenants

• Assess selected sites as options to accommodate the relocated tenants

• Estimate costs associated with the required building improvements

• and catalyze the development of a DD 1391

This Planning Charrette studied the tenant program requirements of Building 137 and 114 occupants, assessed the physical conditions of Buildings 114, 218 & 125, considered required renovation work to accommodate tenant needs, and determined an implementation approach to facilitate relocations of the tenants to new locations in the selected buildings.

PREFACE CONT’D

b. Study Process and Objectives

This repor t is based upon a five day planning charrette held on November 3rd through 7th, 2014 at For t Hamilton, Brooklyn, NY. The charrette process was designed as a group of sequential work sessions and interviews to gather broad input from Garrison Command and specific requirements from impacted stake holders. Facility tours with members of the Directorate of Public Works (DPW) familiarized the design team with existing conditions, building attributes and local resources. This process defined the programmatic needs of the proposed tenants and provided a basis for this repor t’s recommendations for implementation.

The results of the charrette are provided within this repor t, including project scope, rough order of magnitude (ROM) estimate of project cost for the recommended solution, implementation strategy and tabbed construct for the DD 1391.

Primary study objectives are as follows:

i. Define the programmatic needs of the impacted tenants:

1. Review current project goals and objectives

2. Gather relevant program and facility information

3. Determine (validate) quantitative requirements

4. Identify future tenant locations and implementation strategies

ii. Evaluate selected buildings and offer recommendations for facility improvements to suppor t future occupancies.

NARRATIVES

V. TECHNICAL NARRATIVES

a. Overview

The QPK design team performed field observations of Buildings 137, 114, 218 and 125 on November 3, 2014. Personnel included architectural, planning, and MEP and environmental engineering to evaluate the existing building conditions, define scope, and provide programmatic cost estimates for the demolition of Building 137 and renovation of Buildings 114, 218 and 125.

A technical narrative of each building follows, providing an overview of the existing buildings architecture, structural/seismic requirements, mechanical / electrical systems, Information systems, site/civil features, anti-terrorism/force-protection concerns, environmental issues and LEED/sustainable design oppor tunities.

The technical narratives are based upon the visual observations, and information obtained from existing building documents provided by the Garrison.

b. General Requirements

STRUCTURAL/SEISMIC REQUIREMENTS

QPK Design was requested to establish a structural scope of work addressing the need for a seismic upgrade to allow Buildings 114, 218 and 125 to conform with the seismic requirements of the current UFCs.

The buildings involved in the project are over 50 years old. Structural engineers have not performed on-site observations. The current condition of the buildings may have an impact on the conclusions of this structural study.

I. Information made available to this office includes the following:

A. Building 114 Original construction drawings dated early 1960’s and par tial drawings of window replacements and a boiler room renovation. Specifications and/or calculations relative to original construction were not available. Specifications, calculations or documents defining physical changes, that may have been made to the building, have not been available.

B. Building 125 Original construction drawings dated early 1960’s and par tial drawings of an undated generator pit addition and room renovation drawings. Specifications and/or calculations relative to original construction were not available. Specifications, calculations or documents defining physical changes, that may have been made to the building, were not available.

C. Building 218 Original set of construction drawings dated early 1960 and a complete set of construction drawings of an addition built in 1986. Specifications and/or calculations relative to original construction were not available. Specifications, calculations or documents defining physical changes that may have been made to the building were not available.

In the absence of subsurface information, seismic site class “D” was used to estimate the seismic design category. A geotechnical investigation will be required to confirm this assumption and exclude the potential of detrimental effects of soil spreading and/or excessive settlements, etc., due to potential soil liquefaction that may occur in this area.

MECHANICAL/ELECTRICAL REQUIREMENTS

In general, the buildings being considered for renovation will need new HVAC, plumbing, electric power, lighting, communication systems, fire alarm systems, and modifications to sprinkler systems. These changes are required to replace antiquated equipment, to meet the new floor plan layouts and occupant requirements, address code compliancy, and improve energy efficiency. Each building varies in its renovation requirements.

HVAC Systems It is proposed that a variable flow refrigeration (VRV) system be utilized to heat and cool the three buildings.

The system would consist of fan coil units located in the buildings, air cooled condensing units on the roofs or located inside the buildings and vented to the outside, interconnecting refrigerant piping and a heat recovery make-up air unit. The number and location of these units will need to be determined based on the building and the layout of the proposed renovations. In office areas and circulation spaces, fan coils will provide supply and return air that is ducted above ceilings. Pathways for ductwork and new chases will be required to run supply air, outdoor air, relief air, and return air to all spaces.

Exhaust systems will be modified, or new systems provided to serve toilet rooms, shower facilities, and other spaces requiring exhaust. Where possible, a heat recovery system will be provided to preheat and precool supply air with the exhaust air.

A new DDC control system will be provided to monitor and control all HVAC systems. Control panels will be provided to allow for future connection to a central base wide energy management system. In general, all spaces will be provided with individual room temperature controls. Adjacent, similar spaces, located in the same building orientation may be controlled as a group. Adjustable frequency drives will interface with the DDC controls to provide variable speed control of equipment where applicable. It is anticipated the DDC system will be capable of providing the following programming:

1. Optimal star t / stop of systems.

2. Time of day scheduling for air handing units, exhaust systems and make-up air systems.

3. Enthalpy economizer control for free cooling where applicable.

4. Maintenance schedule for all new equipment based on programmable intervals and runtime.

5. Variable speed control of air handling units based on duct static pressure.

53QPK DESIGN

6. Trend log of energy consumption, alarms, equipment points, etc. for all new equipment.

7. Alarms for high limits, low limits, and equipment failure.

Plumbing Systems New toilet rooms will be provided in each building. New piping, plumbing fixtures, and associated trim will be provided. All fixtures will be low flow type fixtures. Energy efficient gas fired domestic water heaters will be provided in each building.

Fire protection Systems It is anticipated that a wet sprinkler system will be provided in all areas. The buildings being considered have par tial or complete sprinkler systems which will need to be extended or modified to conform to the new floor plan layouts.

Electrical Systems Normal Power: Power to For t Hamilton is provided by Consolidated Edison and consists of four main

26.4 kV feeders entering the campus and serving the base substation. The substation transforms the

26.4 kV to 4160 V for campus distribution. Distribution is by a mix of overhead and underground feeders.

The individual building services are provided by either pole mounted transformers, pad mounted transformers, or transformer vaults located within the building. Primary power is metered by ConEd with additional meters located at each building to track power consumption.

There are no repor ted power issues with the overall electrical service to the base.

Emergency Power A 150 kW/187.5 kVA diesel generator with an automatic transfer switch is located in the basement level of Building 114. Building 125 has a manual transfer switch with a generator tap box to accommodate a temporary generator. Building 218 has no provisions for emergency power.

Lighting Lighting generally consists of fluorescent fixtures. It is recommended that LED type lighting fixtures compatible with the new ceiling systems be provided for renovated spaces. Interior rooms and office spaces will have multilevel lighting controls with task lighting at desks. All office and conference room type spaces will receive automatic lighting controls consisting of occupancy or vacancy sensors.

Exterior lighting will be controlled by a time clock and the building energy management system. New edge lit type LED signs with battery back-up and self-diagnostics will be provided. Emergency lighting will be provided by self-contained emergency packs in the normal lighting fixtures.

Communications A typical office space will be set up for a minimum of two computers. Wireless access points will provide coverage to conference rooms and office spaces. Poke through devices under conference tables will provide connectivity of telephone and data to system furniture.

SIPRNet and classified telephones will be provided in the OME.

Special Systems Security: Access control (dual technology card & PIN) and a CCTV camera will be provided to the SCIF entrance. CCTV camera infrastructure will be provided for full exterior coverage and selected interior area coverage around Building 114.

54QPK DESIGN

Technology Infrastructure for overhead projectors and roll-in large format touch screens are provided for conference rooms.

Fire Alarm and Mass Notification System All buildings reviewed under this task order have a fire alarm system. However, only Building 114 has a panel that may be expanded to provide a code compliant fire alarm and mass notification system.

SimplexGrinnell is the recommended manufacturer due to compatibility with the base fire depar tment receiving station. Communication to the Ft. Hamilton receiving station (For t Hamilton Fire Depar tment) is generally through dedicated fiber optic cabling with Building 114 repor ting through a 6-pair copper cable connection.

Each building renovation under this task order will provide a system that repor ts to the fire depar tment central station individual point alarms.

ANTI-TERRORISM/FORCE PROTECTION REQUIREMENTS

Force Protection and Anti-Terrorism Standards UFC 4-010-01, 9 February 2012, change 1,dated 1 October 2013 and UFC 4-010-02 9 February 2012 are considered applicable to Buildings 114, 218 and 125. It is possible that buildings 218 and 125 may become exempt from mandatory application of the standard once replacement value is made available and cost of alterations/renovations is compared. For the purpose of this narrative it is assumed that the improvement costs will exceed the 50% existing building values (paragraph 1-8.2.1) and ATFP standards will be applied.

All three facilities are sited within a controlled perimeter with parking and access roads within that perimeter. The following standards would apply as noted:

• Standard 1 – Stand-off Distances.

• Standard 2 – Unobstructed space.

• Standard 3 – Drive-Up Drop-Off Areas.

• Standard 4 – Access Roads.

• Standard 5 – Parking Beneath Buildings or on Rooftops. Not applicable.

ENVIRONMENTAL REQUIREMENTS

Environmental Systems On November 3, 2014, a walkthrough was conducted for the referenced buildings located at For t Hamilton, Brooklyn, New York. The intent of the walkthrough was for design staff to familiarize themselves with building layout and discuss office space needs. Several repor ts associated with the environmental conditions of the buildings were provided by Peter Koutroubis who is For t Hamilton’s Environmental Manager. The repor t files that he provided include:

• Building 125

• LEAD PAINT SURVEY (4/1995)

• ACM Survey

• Building 218

• LEAD PAINT SURVEY (4/1995)

• ACM Survey

• Building 114

• Limited Lead Paint Repor t (3/2009)

• ACM Repor t (6/2008)

• Building 137

• A tank closure repor t (9/2010)

It is understood that the project will include razing Building 137, and complete floor-by-floor demolition and remodeling of Buildings 114, 125, and 218. Generally speaking, the main items that have the potential to have a major impact of the cost of this type of work is asbestos containing materials (ACM), PCBs in building materials, and lead based paint. A review of the documents referenced above suggest that

previous investigations were limited, and focused only on areas that were expected to be disturbed based on “renovation design drawings” prepared by third par ties. As a result, it is suggested that each of the buildings referenced above undergo a pre-demolition survey for asbestos, PCBs in building materials, and lead.

Site Utilities The majority of the site utilities will not require modification, however some buildings will require modification, and all will need fur ther analysis to determine if the existing services are adequate to serve the new occupancy.

SUSTAINABILITY REQUIREMENTS

Sustainable Design Consistent with the United Facilities Criteria for High Performance and Sustainable Buildings, the proposed For t Hamilton Renovations shall follow the USGBC, LEED™ 2009 rating system, silver level criteria, for new construction and major renovations. (Silver level cer tification requires 50 – 59 points)

Following the Technical Narratives for Building 114, 218 and 125 are LEED™ project checklists, (defining credits pursued to achieve silver level cer tification). Credit pursuits were selected based upon the characteristics of the site, building type, use and project budget. The economic viability of the pursued credits should be reviewed and updated at each subsequent project phase.

Environmental Benefits Conserve Energy: Proposed new HVAC systems, building envelope enhancements, LED lighting, lighting controls and systems commissioning will contribute to efficient energy use. Automated building controls may be implemented to maximize energy performance as recommended by the LEED program. Glazing systems shall be selected to have low-E coatings and low solar heat gain coefficient.

Save Water and Resources: The selection of materials and systems shall be prioritized to consume fewer resources. Installation of low flow water fixtures and sensors will contribute to water use reduction.

Utilization of sustainably grown lumber (FSC cer tified), selection of recycled and renewable materials will be specified where appropriate and practical.

Reduce Erosion and Pollution of Waterways: Green stormwater management practices reduce waterway erosion and pollution caused by runoff.

Reduce Waste: Each project should incorporate a construction waste management and disposal plan requiring recycling of metals, wood, concrete, cardboard, etc. to significantly decrease the amount of solid waste added to landfills. Recycling locations will be integrated into the design to promote occupant recycling. The LED lighting will minimize fluorescent lights containing mercury.

Economic Benefits Reduce Operating Costs: Reductions in energy and water use result in cost savings on utility bills.

57QPK DESIGN

Constructed in 1953, Building 137 was originally built as a six story residential structure with two stories of parking and storage space below. Each above grade floor occupies approximately 17,400 SF. The building is designed in a cruciform layout, with three wings (“A”, “B”, & “C”). Currently, only the “C” wing is occupied, primarily for office and administration used by military and civilian personnel.

Previous structural engineering repor ts by others have indicated that this building has structural deficiencies in the two basement levels due to long term water infiltration. As a result, timber shoring has been installed to provide suppor t for the stories above as a stop gap measure to temporarily extend building use. Access to the basement spaces is not permitted.

Due to the life safety risks caused by the structural deficiencies, the Garrison has been directed by the Depar tment of the Army to demolish this building by 2016.

BUILDING 137

58QPK DESIGN

i. Architectural Building Structure The building is constructed of a concrete encased steel internal frame with load bearing, non-reinforced, masonry exterior walls and cast in place concrete floor slabs on basement through first floor. Timber floor joists are repor ted to suppor t the second through roof levels. The core stair towers and elevator shaft are masonry or concrete construction. The exterior of the building is clad with stucco, exterior insulated finish system, that was observed to be in poor condition.

Each wing is equipped with an elevator and one egress stair (egress is not code compliant).

Demolition This building is recommended for demolition by deconstruction. Scope shall include removal of structure in its entirety, including foundations and basement slabs.

Non-hazardous demolition debris should be recycled or salvaged to the greatest extent possible to diver t disposal in landfills and incineration facilities.

ii. MEP Utility Services It is recommended that the following site utility work be performed prior to demolition of the Building 137.

Water: The water line serving the facility has a main grid shutoff valve. It is recommended that the water be shut off, the water piping removed between the building and the shut off valve and the line capped at the valve.

Sanitary: It is recommended that the sanitary line serving the building be removed back to the main and capped at the demolition boundary line.

Storm systems: An analysis of the storm system catch basins will be required to evaluate if there is enough capacity to handle the newly configured site that is left after the building is demolished.

Gas: It is recommended that the gas line serving the building be removed back to the main and capped at the demolition boundary line.

Electrical: It is recommended that electrical lines serving the building be removed back to the nearest structure or pole to remain. Copper and fiber optic communication lines shall be removed back to the nearest structure beyond the demolition boundary line.

There is an overhead electric and communication line that runs along the southeast (back side) and south-west sides of the building. The lines contain the 4160 V “A” service loop and fiber optic cabling serving the nor thern side of the base as well as other communication lines. These lines need to be relocated to allow demolishing of Building 137. The path and method (overhead or underground) of relocation requires additional assessment to determine the desired routing.

iii. Environmental Lead Paint Based on the age of the building it seems likely that lead based paint may be present throughout the building. To identify the lead based paint a survey should be completed that includes collection of bulk samples for TCLP lead analysis under the Resource Conservation and Recovery Act.

Asbestos Containing Materials A pre-demolition asbestos survey is required, however, no documentation has been provided suggesting that an asbestos survey has been completed. The pre-demolition survey is required so that ACM can be identified and abated before demolition proceeds. If no, pre-demolition asbestos survey is completed then demolition debris will need to be managed as ACM which will increase the cost of the project. Based on the age of the building, and limited survey repor ts it is reasonable to assume that ACM is present in some of the buildings. The types of materials that could contain ACM include, but are not limited to, floor tiles, mastics, window caulk, and joint compound.

PCBs in Building Materials It does not appear that a PCBs in building materials survey has been completed for Building 137. Based on the age of the building it is possible that window caulks, some layers of paint, building materials, and masonry caulks may contain PCBs. A PCBs in building materials survey should be completed prior to any renovation activities.

Underground Storage Tanks (USTs) Two 25,000 gallon heating oil USTs are located in proximity to Building 137. The tanks were repor tedly abandoned in-place with an iner t concrete like material. It is recommended that the USTs be removed during demolition. Based on laboratory data provided by base environmental staff some residual contamination was detected in subsurface soils, therefore, if the USTs are removed it is likely that contaminated soil may be encountered that may require management.

Universal Waste Electronic Waste, and PCB Containing Light Ballasts. Universal wastes (eg. Batteries for emergency lights, fluorescent light bulbs, mercury containing thermostats), and electronic waste (e.g. computers, CRT moni-tors), and light ballasts should be inventoried prior to demolition. These items will require appropriate management.

iv. Civil/Site Site Restoration Once the building is removed, the basement and foundation areas should be back-filled with clean type fill and compacted to prevent ground settlement. It is recommended that a layer of topsoil be installed and lawn or ground cover be planted to stabilize the soil and prevent erosion. Storm water drainage and runoff design be required to be developed the following project phases.

60QPK DESIGN

Constructed in 1962, Building 114 was originally built as a two story medical facility. Each above grade floor occupies approximately 15,000 SF. The building is designed in a linear layout, running nor th/south, with a central corridor and two main entrances positioned at third points, facing White Avenue. The basement is primarily accessed through a small tunnel below an overpass drive on the south end of the building.

Original program spaces ranged from medical, office, exam, procedure and operating spaces to dental and veterinarian facilities. The building use has evolved over the years and currently houses a wide array of functions including:

• Government Travel / Passpor t office / ID Card Services

• DHR / Work Force Development / Military Personnel

• Substance Abuse program

• Logistics Readiness Center

• Civilian Personnel office

• Public Affairs office

• DVA Credit Union

• Army National Guard Unit

• Pharmacy

• Medical Recruiting

It is anticipated that this building will get a complete gut and rehabilitation to meet the new programmatic needs as defined in this repor t.

61QPK DESIGN

Building Structure The building frame is constructed of cast-in-place reinforced concrete columns, cast in place concrete floor and roof slabs. The structure is suppor ted by reinforced concrete basement and foundation walls on spread footings. No visual signs of structural issues were repor ted or observed. Interior par titions are non-load bearing and reconfiguration of walls for future renovations are possible.

Exterior The building exterior construction is brick cavity wall construction with a 2” air space and 4” Concrete masonry unit back up. Per existing building drawings, exterior walls are not insulated. Some signs of water infiltration and or deterioration was observed at several locations on the building exterior:

• Nor th end wall at first and second story ceiling levels

• Central east elevation

• Several locations at window sills • Concrete spauling at area ways

Fur ther investigation and repair of deteriorated brick areas should be included in future phases of the project.

62QPK DESIGN

Roof deck is cast in place concrete covered by a modified bitumen roof system, approximately 10 years old. Secure fall protection tie in points were observed on the roof. No current leaks repor ted. Roof test cuts are recommended to assess system configuration including amount and condition of insulation.

Windows and main public entry’s are aluminum with insulating glass. Most are not original to the building.

Per visual assessment, it is anticipated that the window systems are not in compliance with current AT/ FP standards.

Utility doors and frames are hollow metal type and should be replaced as par t of the building renovation.

Due to the construction of the existing exterior walls, including lack of insulation, structural reinforcement, and AT/FP window replacement scope, it is recommended for the exterior building envelope to be replaced with a new wall system.

The new exterior envelope should be designed to current energy code standards and include reinforcing to accommodate blast resistant compliant windows.

Interior The Building has four primary exit stairs and one elevator is provided. Current stair hand and guard railings are not compliant and will require enhancement or replacement in the renovation project.

63QPK DESIGN

Interior par titions are typically concrete block with plaster finish. Corridors are fur ther enhanced with a glazed terracotta tile wainscot. Floor finishes are primarily vinyl tile (should test for asbestos content) and ceilings are lay in type, with some plaster in areas such as vestibules and non-renovated offices. Some areas of paint adhesion problems were observed in various areas of the building.

Doors are primarily hollow metal type.

The DVA Credit unit located on the first floor is newly renovated. We have learned that the Credit Union will no longer remain in this building.

It is anticipated that most interior par titions will be removed and replaced in the renovation project. The elevator should be evaluated for code compliance and up-graded as required.

ii. Structural/Seismic Building 114 was constructed in 1960. The structural system consists of reinforced concrete columns suppor ting two levels of two-way flat slab floors with perimeter spandrel beams and one level of one-way concrete joist roof slab. The building is two levels plus a basement.

A one inch wide expansion joint divides the building into two structural independent segments. The roof level framing, at the nor th end, incorporates cantilevered reinforced concrete joists. The reinforced concrete roof cantilevers and a por tion of second level low roof flat areas may be susceptible to deterioration and should be examined.

The exterior walls are un-reinforced masonry (URM) incorporating a 4 inch veneer and 4 inch backup wall with a 2 inch air space. The existing walls may require modification to resist lateral loads.

Our understanding of the design objective, in regard to progressive collapse, is that Building 114 must meet minimum provisions for prevention progressive collapse as it consists of two elevated levels and one occupied basement.

Preliminary Scope of Structural Retrofit Work

Based on our knowledge of the building we anticipate the following scope of structural work for Building 114:

1. Evaluation of existing condition of structural components.

2. Possible remedial work of areas affected by deterioration.

3. Geotechnical investigation for confirmation of assumed seismic soil classification and exclusion of liquefaction potential.

4. Tier 3 seismic evaluation and seismic retrofit design based on defined objective and hazard level.

5. Removal and replacement of exterior URM walls and replacement with system comprised of reinforced shear walls and ductile framing of window openings adequate to resist AT/FP blast protection requirements.

6. The elongated shape of this building results in a large diaphragm aspect ratio of length to width. Additional reinforced concrete shear walls may be required in the building transverse direction. Ver tical alignment of these walls, through the entire height of the building, will be required to avoid effects of seismic system irregularities. Some additional construction of foundations should be anticipated for suppor t and transfer of forces from transverse shear walls to underlying soil.

7. Elimination of the expansion joint may resolve remediation of a potentially insufficient seismic separation between the two building segments.

8. Progressive collapse mitigation of exterior structural framing. Additional columns/foundations may be required.

SUMMARY OF FINDINGS

HVAC Systems The existing HVAC systems located in the building are not adequate due to a number of factors including lack of cooling capacity, age of systems, equipment inefficiency, condition of equipment, and inability to adequately control the systems. Systems are old and have exceeded their ASHRAE estimated useful life. It is recommended that all systems be replaced.

At this point in time the cooling load associated with the 46,000 square foot building is estimated at approximately 130 tons. The heating load is estimated at approximately 921,650 Btu/h. Actual heating and cooling requirements will need to be determined once space usage is established.

Plumbing Systems The plumbing system in the building appears to be original. It is recommended that the cold water, hot water, vent, sanitary, storm piping within the building and fixtures and trim be replaced.

Fire Protection System A fire protection system would be provided in all areas.

Electric Systems It is recommended that the service be up-sized and provide new power distribution, emergency power, lighting, communications, fire alarm and mass notification, and security systems be replaced.

Site Utilities Water: Facility personnel stated that the water pressure and flow are adequate at the building. However, it is anticipated that the site water laterals will need to be replaced.

Sanitary System: It is anticipated there will be sanitary system modifications associated with the project.

Storm water: It is anticipated there will not be site storm system modifications associated with the project.

Gas Service: No changes are required for the natural gas system serving the building.
