INTRODUCTION AND SCOPE OF WORK
Per the request of the City of Brea, Griffin Structures performed an analysis of the estimated construction
cost to design and construction a 6-level, 615 stall, parking structure per the plans generated by Jamboree
dated June 3, 2015.
Task #1
Review the Jamboree design and construction budget for the parking structure only to provide an
independent opinion of cost.
Task #2
Provide a comprehensive total budget to design and construction the Jamboree parking structure solution
using a Design-Build delivery method administered by the City of Brea.
TASK #1 REPORT
Jamboree Budget Analysis
Griffin Structures, Inc. with the assistance of Bomel Construction reviewed the plans and budget
prepared by Jamboree. The following summary represents our review and conclusions of the Jamboree
Budget:
•
•
•
•
•
•
Proposed parking structure is a 6-Level, 615 stall, parking structure with (2) levels of
subterranean and (4) levels above grade.
Delivery method is Design-Build
It is assumed that prevailing wages are included the budget
Total budget is $14,477,767 as estimated by Jamboree
Cost per square foot is $62/GSF as estimated by Jamboree
Cost per stall is $23,541/stall as estimated by Jamboree
Griffin Structures and Bomel Construction produced an independent estimate based on the same
Jamboree design, assumptions, qualifications, quantities, and units and the following are the results of
this independent estimate:
•
•
•
•
•
Jamboree estimate is $14,477,767
Bomel estimate is $15,573,697
Cost per square foot is $66/GSF
Cost per stall is $25,323/stall
Variance is $1,095,930 or 7.5% higher
Note: See Appendix A for detailed cost estimate comparison

Project Schedule
The Jamboree estimate did not indicate an overall timeline to design and construct only the parking
structure. Griffin is estimating the following overall timeline to design and construct only the parking
structure as the first phase of the Jamboree mixed use project. Overall timeline is based on (28) months
from when the City initiates the start of preparing the RFP,
Preparation of RFP and Pre-Qualification Phase – 4 Months
•
•
Complete the RFP and Bridging Documents – 4 Months
Pre-qualification of Design-Build teams – 3 Months
Note: Preparation of RFP and Pre-Qualification to be concurrent tasks
Issuance of RFP and Selection of Design-Build Contractor – 3 Months
•
•
RFP Response Period – 1 months
Selection of Design-Build Contractor and Award of Contract – 2 Months
Design, Plan Check, and Permits – 7 Months
•
•
Design Development and Construction Documents – 5 months
Plan Check and Permits – 2 Months
Note: Permits will be phased with Demolition/Grading/Site Utilities being a separate permit
followed by the Building Permit being issued as construction is underway on the initial phase of
work
Construction and Project Close-Out – 14 Months
•
•
Construction Phase – 12 months
Project Close-Out – 2 Months

TASK #2 REPORT (con’t)
Jamboree Parking Structure Master Budget
Note:
Due to the fact that the Jamboree parking structure is based on a mixed use project with both commercial
space on-top of the parking structure and residential on-top of the subterranean parking levels the ability to
generate a RFP and bridging document package for only a design-build parking structure will be complex
and challenging for the City. The primary challenge is the need to have multiple design firms (parking
structure, commercial, residential) providing preliminary but also reliable and complete engineering to
accommodate the future commercial and residential components that would traditionally be designed by a
separate A/E team. A mixed use project that is designed and constructed in phases is traditionally planned
and fully designed (design-bid-build) by a single prime consultant knowing that multiple factors need to be
considered for full coordination amongst the various architectural and engineering disciplines. It is not
typical to carve out only a parking structure of a mixed use phased project and deliver using a public sector
design-build delivery with only having the parking structure developed into bridging documents. This will
be important to acknowledge as this approach can affect project budget and the overall schedule timeline.
This phased project delivery requires further study to ensure the City of Brea understands the complete and
required effort to accomplish these goals.
