SUBJECT: POS Maintenance Warehouse Building 2 Demolition 
(WP# 200101; CIP C001760) 
Amount of This Request: $ 0          Source of Funds: Airport Development Fund 
Third Runway Project Authorization to Date Including this Request: $1,128,956,000 
State and Local Taxes Paid Expected to be paid: $83,000 (total demolition project) 
Total Estimated Project Costs: $1,351,000                   Jobs Created: 20 
ACTION REQUESTED: 
Request Port Commission authorization for the Chief Executive Officer to advertise and execute
a major construction contract for the POS Maintenance Warehouse Building 2 demolition,
located within the South Runway Protection Zone (RPZ) of Runway 16R/34L (also known as the 
Third Runway). The budget for this request is included in the previously authorized budget for
the Third Runway Project. 
SYNOPSIS: 
The vacant POS Maintenance Warehouse Building 2 is the last remaining building to be
demolished as part of the construction and activation of Runway 16R/34L. T he Federal Aviation
Administration (FAA) safety regulations require vacation of the RPZ which lies directly to the
south. No additional budget is necessary to complete this demolition project. It will be
competitively bid. 
BACKGROUND: 
The final phase of demolition within the South RPZ of Runway 16R/34L was authorized in
August of 2006. With numerous delays in the construction of the new POS Maintenance facility,
permission was granted by the FAA to extend the occupancy of this final building within the
South RPZ until the new Maintenance Facility could be completed. The Maintenance Facility
has now been completed and the old POS Maintenance Warehouse Building 2 is vacant and
ready for demolition. 
This authorization will allow construction bids to be obtained for the scope of work under the
overall Third Runway Project. Although the runway is operational, certain projects associated

with the runway must be completed as required by other agencies like the FAA and before the
overall project will be complete. No additional budget is being requested. Sufficient budget for
this work within the Third Runway Project has already been authorized by the Commission. 
The cost of this work is estimated to be $1,351,000. 
PROJECT JUSTIFICATION: 
Project Objectives:

the South RPZ for Runway 16R/34L as directed by the FAA, in accordance with approval of the
Third Runway project.

Project Cost Breakdown: 
Construction Costs                            $905,000 
Sales Tax                                   $83,000 
Aviation Project Management and other soft costs        $250,000 
Total                                      $1,351,000 
Budget Status and Source of Funds: 
This project is included in the 2011-15 capital budget and Plan of Finance within the Third
Runway Program (CIP #C001760). The funding source will be the Airport Development Fund. 
Financial Analysis and Summary: 
These estimated costs will not cause the total projected costs to exceed the revised budget, and
will not affect cost per enplanement (CPE) as these projects were already included in the CPE
forecast. While the cost for this requested action will increase CPE by less the $.01, there is no
change to the business plan forecast as this project was included. 
Lifecycle Cost and Savings: 
There is no life cycle cost associated with the demolition of this project. 
ENVIRONMENT AND SUSTAINABILITY:
This demolition project is utilizing the Port's new Construction Waste Management
specification. The specification requires the contractor to divert at least 75% of construction,
demolition, or land clearing materials from the project through salvage, reuse, or recycling.
This building was found to contain regulated levels of polychlorinated biphenyls (PCBs). Prior
to the demolition of the building, the construction contractor will be responsible for removal of
all PCB containing materials. Aviation Environmental Programs will manage disposal of these
materials in coordination with the removal by the contractor. 
STRATEGIC OBJECTIVES: 
This project supports the Port's strategy to "Ensure Airport and Seaport Vitality." 
BUSINESS PLAN OBJECTIVES: 
Demolition of identified buildings within the South RPZ of Runway 16R/34L is in compliance
with the safety concerns and regulations outlined by the FAA. 
TRIPLE BOTTOM LINE SUMMARY: 
Demolition of this building in the South RPZ is a requirement of the FAA regarding life safety in
the vicinity of Runway16R/34L. Final agreement with the FAA stated that the building would
be demolished by the end of 2011. It is the Port's understanding that beginning demolition of the
POS Maintenance Warehouse Building 2 by the end of 2011 is acceptable to FAA. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternatives in this project have been exercised in the delays previously requested of the FAA in
order that the POS Maintenance could remain in the building until a more appropriate site could

be constructed. The alternative of further delaying demolition of the building or to not demolish
the building would result in the Port not complying with FAA safety regulations. Neither of 
these alternatives is recommended. The recommendation is to proceed with the de molition
project as currently scheduled in order to fulfill the Port's commitment to FAA and comply with
FAA safety regulations.
