C1 Project Scope
The C1 project provides for the re-use and redevelopment of the existing three floor
building (redeveloping the concourse level and first expanded floor) into publicly
accessible space to accommodate new dining and retail spaces.

The project expands up four additional floors to provide office and lounge space. It
creates a rooftop mechanical penthouse, an additional expansion of the C3 hold room
(additional gate seating) and adds a loading dock.

There will be no added gates nor additional airplane operations as a result of the C1
project.

C1 Building Overview
Four additional floors on top of existing two-
story C1 Building                                                                                    Two Levels of
Lounge/Office/Mech
anical
70K sf of incremental office/lounge/ space.
25K sf of additional ADR space
(30K+ sf deficiency based on 2016 ADR study)
Additional public space consisting of more
seating in the congested C3 gate area, new
public restrooms and additional public
amenities, including 670 SF of nursing
mother's space and 722 SF of meditation
space.

Sustainable Project Framework
C1 is the Airport's first Tier 3 project
SPARC (Sustainability Project Assessment and Review
Collaboration)
- Identified key project analyses
Sustainable Design Approach
- Requires designers to conduct range of sustainability and cost
analyses
Port staff will review results and develop recommendations in
Sustainable Design Strategy
Consult with Commission's E&S Committee at 30% design

C1 - Diversity in Contracting
Diversity in Contracting (WMBE) Aspirational Goal Range for C1:
Design                   Construction
9%-15%               8%-15%
A final goal will be established before we advertise.
The Port-Gen C1 Project informational meeting on February 26 had over 120 guests.

Design Approach
Design Status and Strategy
Project Definition Document created (PDD)
Utilities and structure have been reviewed by engineers
Designer will be required to have experience "designing to budget"
Port design reviews will be limited to key personnel
Design Success
Designing to budget
Using architectural elements to draw passengers to 2nd floor ADR spaces
Creating an open and well-lit environment

12

Project Delivery
General Contractor / Construction Manager (GCCM)
The GCCM will provide and extensive survey of existing conditions in
the C1 Building
Provide a construction estimate at each major design milestone. This
approach will assist with the project team's goal of scope and budget
control.
The GCCM will provide essential input on project phasing.

Project Status             The C1 PDD was approved by the
Managing Director of the Airport on
January 17, 2020.
Still  pending  in  Status  3,  is  Airline
