City Council Report
City Council Meeting: October 24, 2017
Agenda Item: 3.C
1 of 4
To: Mayor and City Council
From: Susan Cline, Director, Public Works, Architecture Services
Subject: Design of Guardrail and Waterproofing Upgrades in Downtown Parking
Structures 1-5
Recommended Action
Staff recommends that the City Council:
1. Award RFP #SP2516 to Walter P. Moore Corporation, a Texas-based company,
for design services for Downtown Parking Structure Guardrail and Waterproofing
Upgrades;
2. Authorize the City Manager to negotiate and execute an agreement with Walter
P. Moore Corporation, in an amount not to exceed $243,100 (including a 10%
contingency);
3. Authorize the Director of Public Works to issue any necessary change orders to
complete additional work within contract authority.
Executive Summary
The guardrails in Parking Structures 1-5, which were built to existing codes at the time
of construction and installation of the parking structure, need to be upgraded to comply
with current codes, and the waterproofing system in Parking Structure 5 needs to be
modified to prevent water flooding into the stairwells during heavy rain events. Both
projects would improve safety and accessibility within the parking garages for residents
and visitors. On July 18, 2017, the City issued a Request for Proposals (RFP) for the
Downtown Parking Structure Guardrail and Waterproofing Upgrades Project. After
reviewing the proposals, staff recommends Walter P. Moore Corporation to perform
design services for upgrades to guardrails and waterproofing in Santa Monica
Downtown Parking Structures 1-5 in an amount not to exceed $243,100 (including a
10% contingency). Design services are estimated to be completed in December 2018.
Background
2 of 4
On June 14, 2016 (Attachment A), Council adopted and approved the FY 2016-18
Biennial Capital Improvement Program (CIP) Budget. Two projects related to parking
structure improvements are included in the approved CIP Budget: “Railing Replacement
Parking Structures 1-5” and “Parking Structure Elevator Shaft Waterproofing.” Funds
identified for each project would be combined and managed under the title “Downtown
Parking Structure Guardrail and Waterproofing Upgrades Project.”
Discussion
The public parking structures, numbered 1-5, located in Downtown Santa Monica, were
constructed in the 1960s. Over the years, a variety of upgrades including seismic
strengthening have been completed on these structures.
The existing guardrails in Parking Structures 1-5 were built in accordance with spacing
requirements in effect at the time of construction and installation, and have been
repaired and tightened periodically. The current code has more narrow steel cable
spacing requirements, and this project would upgrade the guardrails to meet these
requirements and provide enhanced life safety for the public. Staff recommended that
the design and installation of new code compliant guardrails be completed in the FY
2016-18 CIP project cycle. Locations affected include:
Parking Structure 1 at 1234 4th Street
Parking Structure 2 at 1235 2nd Street
Parking Structure 3 at 1320 4th Street
Parking Structure 4 at 1321 2nd Street
Parking Structure 5 at 1440 4th Street
Parking Structure 5 also requires a new waterproofing system to mitigate water intrusion
problems occurring in the structure’s elevator shaft and stairwells. During heavy storm
events, rainwater landing on the roof deck runs directly into the structure’s stair and
elevator shafts, resulting in pools of water at the stairwell landings and heavy flooding

on the ground floor. Modifications would need to be made to the structure’s roof, and to
the existing openings in the stairwells, which would also require protection.
Vendor/Consultant Selection
On July 18, 2017, the City issued a Request for Proposals (RFP) for the Downtown
Parking Structure Guardrail and Waterproofing Upgrades Project. The RFP was posted
on the City’s on-line bidding site, and notices were advertised in the Santa Monica Daily
Press in accordance with City Charter and Municipal Code Section 2.24.075(a)
provisions. A total of 44 vendors downloaded the RFP. Six firms responded. Responses
to the RFP were reviewed by a selection panel of staff from the Public Works and
Planning and Community Development departments.
