SCOPE OF SERVICES

MONROE COUNTY
KEY WEST INTERNATIONAL AIRPORT (EYW)
ENGINEERING DESIGN AND BIDDING SERVICES
FOR THE
CUSTOMS AND BORDER PROTECTION FACILITY — PHASE III TO FINAL
SUPPLEMENTAL SERVICES FOR ROOF REPLACEMENT, HVAC IMPROVEMENTS AND
STRUCTURAL FOUNDATION EVALUATION
I. PROJECT UNDERSTANDING
The McFarland Johnson (MJ) Team is currently working on the architectural and
engineering design for the Annex Building / Customs and Border Protection Facility
improvements at Key West International Airport. These improvements include
implementation of a new internal layout of the building to accommodate an expansion and
improved functionality of the current CBP facilities.
During the design team's initial evaluation of the existing building, CBP and Airport staff
noted that the existing Annex Building has ongoing issues with roof leaks, and that the
existing HVAC roof top units were assumed to be one of the sources for the leaks.
Additionally, during the team's initial evaluation of the existing building, Airport staff noted
that the existing Annex Building foundation columns were cracking and spalling.
As a result of the above conditions, the MJ Team has been asked to provide a
supplemental proposal to address re- roofing of the existing building, and the replacement
of the existing roof top HVAC units with a new air - cooled chiller plant serving Variable Air
Volume (VAV) air handler units, as well as provide a supplemental proposal to evaluate
the existing building columns and provide a recommendation for repair.
The work in this supplemental re- roofing and HVAC design will consist of Architectural
and Engineering Design Services for preparation of construction documents, plans, and
specifications, for the re- roofing of the Annex Building and replacement of the existing
HVAC system with a new system. The work in this supplemental foundation evaluation
will consist of Material Testing and Structural Engineering Design Services to determine
the cause of the distresses (as shown in photos below) and provide repair details.

Task Order 2017 -02A
II. DESIGN PHASE - ROOF REPLACEMENT AND HVAC
A. Existing Conditions Evaluation - Perform preliminary field investigation of the
existing Annex building roof system, HVAC system, and associated structural
support and utility connections. Review of as -built information (drawings, calcs,
etc.).
B. Roof Design - It is anticipated that the existing roof will be removed, including
insulation down the structural deck, and new insulation and roofing will be installed
prior to the completion of any improvements to the internal layout of the building.
Coordination with HVAC rooftop unit removal and infill of existing openings will be
provided. Roofing Design to consist of the following documents:
1. Roof Demolition / Existing Conditions Plan
2. New Roof Plan with layout of tapered insulation slopes, drains, and roof top
equipment located.
3. Roofing details for typical roof section, roof drains, wall flashing, parapet
flashing, etc.
4. Specifications for roof system, insulation, and roof accessories.
5. Florida Product / Miami Dade Product Approval NOA identification for rated
roof system approved for the project wind zone.
C. HVAC Design — The new HVAC system shall include an air - cooled chiller, modular
VAV air handlers and VAV terminals utilized for zone control. The air - cooled chiller
shall be mounted on a platform providing service access with elevation of

approximately 10' -0" above finished grade. The chiller shall include integral chilled
water pumps, expansion tank. Air handling units shall be mounted in mechanical
space and abandoned generator room at 2 nd level /mezzanine. Preliminary design
assumptions: four (4) air handlers sized at 6000 cfm each with variable speed drives.
Variable volume terminal units shall be located in ceiling plenum. Due to low
clearance above ceiling (approximately 20" from ceiling to structure) the VAV
terminals will be low profile type. It is proposed that a return air plenum be used
similar to the existing conditions. IT cabling /wire located in this area will be "plenum
rated ". Electric heating coils shall be provided in VAV terminals to meet the heating
loads. Energy recovery shall be considered for pretreatment of the outside air and
CD
reducing the HVAC building load. It is anticipated that the total cooling system load
for the Annex Building will be approximately 60 tons. Dedicated mini -split systems CD
shall be provided for LAN and IDF rooms. Exhaust shall be provided for restrooms, L_,
janitor closet and locker area. HVAC Design to consist of the following documents: E
1. HVAC System Demolition / Existing Conditions Plan
2. HVAC System Construction Phasing Plans
3. New HVAC System layout Plans
4. HVAC system Details
5. Electrical power distribution plans for new system, including circuiting,
raceway, and disconnecting means.
CD
6. Specifications for new HVAC system.
An alternative HVAC Design will be considered, which includes a Variable
Refrigerant Flow System (VRF) utilizing several indoor DX air handling units served
by a common outdoor condensing unit with manifolded refrigerant piping. The
advantages of this system are that construction phasing of the interior renovation
could easily be accomplished by providing new small capacity indoor air handlers
mounted in the ceiling for each space. The smaller ductless units would readily fit
within the limited ceiling clearance. These small air handlers called "cassette" units
are designed for grid ceiling installation and have their own thermostat providing
zone control. The VRF systems are very efficient with high EER ratings.
Disadvantages are maintaining numerous above ceiling units and a dedicated 100%
outdoor air unit would be required to provide ventilation air to all spaces. The VRF
outdoor units typically come in sizes up to 20 tons; three (3) — 20 -ton systems would
be required to serve the entire facility.
III. DESIGN PHASE — FOUNDATION EVALUATION
A. Existing Conditions Evaluation — Preliminary site visit to select core locations and
verify access of the locations for coring equipment.

Task Order 2017 -02A
B. Concrete Coring — A sample size of seven (7) columns will be cored (3" diameter).
Six cores will be extracted from distressed concrete and one core will be extracted
from concrete showing no distress. Selected core locations will be scanned with
ground penetrating radar to minimize the chance of cutting of any reinforcing steel
within the concrete structure. Core holes will be patched with a high strength repair
mortar, BASF 10 -61, or approved equal.
C. Material Testing:
1. The same day as the cores are extracted from the columns, they will be
subjected to a Phenolphthalein indicator solution on the fresh cut surface of
CD
the cores to check for the degree of carbonation that has occurred in the
CD
concrete.
2. Two of the core samples from distressed locations, along with the one core
E
from a non - distressed location, will be subjected to petrographic analysis. The
Petrographic Analysis will be completed in substantial compliance with ASTM
C856 -04, "Standard Practice for Petrographic Examination of Hardened
Concrete ".
As part of petrographic analysis, a portion of one core sample will
be tested in accordance with ASTM C642, Standard Test Method for Density,
Absorption, and Voids in Hardened Concrete.
3. One -inch thick wafers will be cut from the outer face of each core sample and
CD
the wafers will be tested for chloride content and pH. Chloride Testing will be
CD
performed on each sample in accordance with rapid German Instruments
Method.
