SUBJECT:  Airport-wide HVAC Controls Upgrade (CIP # C800497) 
Amount of This Request:   $274,000     Source of Funds: Airport Development Fund 
Est. State and Local Taxes: $148,000      Est. Jobs Created: N/A 
Est. Total Project Cost:    $2,157,000 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to proceed with the Airportwide
Heating Ventilation & Air Conditioning (HVAC) Controls Upgrade project, and direct staff
to prepare design documents. The total amount of this request is $274,000 and the total
projected cost is $2,157,000. 
SYNOPSIS: 
Commission authorization is requested to proceed with design of the Airport-wide HVAC
Controls System. The existing system controls and/or monitors a very large and spread out
system that serves the Airport terminal campus. The controls system includes the heating and
cooling, water pumping and distribution, ventilation, cooling towers, central plant, smoke
control, natural gas and water metering, and waste pumping demands of the Airport. 
The current system suffers from significant performance issues due to obsolescence and the mix
of network types and the overall number of aging devices on the serial communications network.
The existing Airport-wide HVAC Controls System network will be upgraded to a modern
ethernet based communications network that can provide sufficient bandwidth and speed to
allow operations and maintenance personnel to better manage the Airport-wide systems.
The control systems in the building facilities located at the South Logistic Center (SLC) are not
currently connected to the Airport-wide HVAC Control System. The existing serial network
does not allow for the addition of a stand-alone system such as the one controlling the SLC. The
new system will add a wireless connection to enable addition of existing facilities such as the
South Logistic Center (SLC), and it will allow the addition of stand-alone systems with separate
servers. This will include future projects in the North and South Satellite Concourses.

The existing system components and software are a Siemens proprietary system. An existing
Competition Waiver is in place that covers the Siemens system. The project specifications will
include the proprietary system and be included in the bid package. 
The design will be developed using the Mechanical-Electrical Indefinite Delivery/Indefinite
Quantity Service Agreement, which has an ordering period end date of April 26, 2014.
This project was included in the 2013  2017 capital budget and plan of finance. 
BACKGROUND: 
The existing Airport-wide mechanical system control network has been evolving over the years
and has been modified as larger mechanical system projects have been executed. The current
network consists of a mix of serial and ethernet communications that connect the servers to the
mechanical systems' field controllers. As a result, the current system suffers from significant
performance issues due to the mix of network types, obsolescence of some components, and the
overall number of devices on the serial communications network.
The existing system currently runs on a local area network which limits the flexibility in adding
stand-alone systems to the airport wide network. The system will be upgraded to an ethernet
based wide area network (WAN). The WAN allows the Airport to add separate stand-alone
systems such as the SLC control system or future systems that may be required, e.g. at the North
and South Satellites. 
In addition to the mix of systems, there are two components of the mechanical control network
that slow down processing of important data. The first component is the existing system copper
"backbone" in Concourse A. This existing copper "backbone" transmits data slowly, creating a
bottleneck. The new ethernet system will replace the copper system to provide a "backbone"
that can transmit at 100 times faster than copper. The second component is the network
hardware and switches. These also need to be replaced to increase data transmission.
The current server and a large portion of the network hardware are at the end of their
useful/supportable life (5-7 years). Technical support is no longer available for the existing
system hardware and software. The server and hardware must be replaced. 
A good faith survey will be completed. Port Construction Services (PCS) will manage the
survey. The areas in question are located in Concourse A, we don't anticipate the need for
regulated materials abatement; however, a good faith survey is required.
PROJECT JUSTIFICATION: 
This request will authorize design services to replace the existing Airport-wide HVAC Control
System with an up-to-date data delivery system that includes a new Ethernet fiber optics
"backbone," up to date hardware, new server, and updated software. The new system will
provide the needed speed and flexibility for current and future needs as well as facilitating the
addition of stand-alone systems such as the existing facilities in the SLC.

communications. 
Update the current system network hardware major infrastructure.
Update system infrastructure hardware (servers and workstations) to replace old unsupported
equipment.
Replace existing server infrastructure in boiler control room, provide new racks and
environmentally conditioned space for new system server and communications

Budget Status and Source of Funds: 
This project, CIP #C800497, was included in the 2013  2017 capital budget and plan of finance
with a budget of $1,800,000. The original budget was developed based on a range of magnitude
and since has increased due escalation, soft cost recalculation, and addition of scope such as the
addition of the wireless connection to SLC. The budget increase will be transferred from the
Aeronautical Allowance, CIP C800404, resulting in no net change to the Aviation Division's
capital budget. The source of funds is the Airport Development Fund.

time, which allows the maintenance staff to diagnose operational problems quicker and therefore
to remedy them quicker. Operational costs will remain the same and are factored into existing
Aviation Maintenance budgets. 
STRATEGIC OBJECTIVES: 
This project will support our Century Agenda Strategic Objective to meet the region's air
transportation needs at the Airport for the next 25 years by ensuring that the infrastructure is
operationally reliable and well controlled. 
ENVIRONMENTAL SUSTAINABILITY: 
This project demonstrates environmental sustainability by improving existing Port assets and
better utilizing existing resources. This project will replace existing equipment with new more
efficient systems. A large portion of the existing materials will be recycled. 
BUSINESS PLAN OBJECTIVES: 
The project will provide a stable, reliable infrastructure that supports the Aviation Division's
strategic goal of operating a world-class international Airport by anticipating and meeting the
growing needs of our tenants, passengers, and the region's economy. 
TRIPLE BOTTOM LINE SUMMARY: 
This project supports: 
The Airport customers by improving response time to mechanical problems which
might otherwise impact travelers comfort (air temperature, water temperature, etc.).
Operational efficiency can be improved with better control and monitoring data mined
from the various mechanical systems at the Airport. 
The environment by recycling a portion of the materials to be removed and by
installing new more efficient HVAC Control System equipment. 
The community by ensuring that the Airport is effective and efficient and therefore can
remain a financially healthy neighbor and good steward of energy among local cities.
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1  Leave the equipment in place and live with the slow response time, lack of real
time data. This alternative represents growing risk to the Port. If an aging component of the
system fails, then the remote monitoring and controlling function fails. HVAC systems would
still operate at the local thermostats and controllers using either the manufacturers or recent set 
points. Equipment malfunctions would not be visible to maintenance staff until customers call in
with problems such as being too hot or cold. This is not the recommended Alternative. 
Alternative 2  Replace the existing HVAC Control System with an up to date data delivery
system that includes a new fiber optics "backbone," up-to-date hardware, new server, and
updated software. The new system will provide the needed speed and flexibility for current and
future needs as well as facilitate the addition of stand-alone systems such as the facilities in the
SLC. This is the recommended alternative.
