Description/Analysis
Issue Detail: The Old Sacramento Boardwalk was constructed nearly 30 years ago, and the wooden boardwalk required replacement. In June 2013, an assessment was conducted, and the report identified the need to install new hand rails, access ramps, rail crossings at J Street, K Street and L Street, detectable warning devices, street crossings along Front Street, as well as the construction of new stamped and colored concrete decking, additional landscaping, lighting, and electrical services. The City hired Unger Construction Company in January 2015 under City Agreement 2015-0029 to design and build the boardwalk improvements.
During construction, the project encountered many unforeseen conditions which increased project scope, particularly in the right-of-way areas at J Street, K Street and L Street. Lack of existing accurate record drawings contributed to the many unforeseen conditions. Unexpected underground deficiencies, including unknown conduit and wiring, irrigation lines, and existing concrete issues at the floodwalls adjacent to existing businesses were some of the more notable issues that were resolved.
Change Order Nos. 4 and 5 were executed for extension of time. All work under the contract has been completed. Change Order No. 6 addresses the unforeseen conditions and increased project scope described above and is required to complete and close out the project.
Policy Considerations: The recommendations in this report are in accordance with the provisions of City Code Chapter 3.60.
Economic Impacts: Change Order No. 6 is expected to create 2 jobs (1.27 direct jobs and 0.73 jobs through indirect and induced activities) and create $263,958 in total economic output ($169,204 of direct output and $94,754 of output in indirect and induced activities).
The indicated economic impacts are estimates calculated using a calculation tool developed by the Center for Strategic Economic Research (CSER). CSER utilized the IMPLAN input-output model (2009 coefficients) to quantify the economic impacts of a hypothetical $1 million of spending in various construction categories within the City of Sacramento in an average one-year period. Actual impacts could differ significantly from the estimates and neither the City of Sacramento nor CSER shall be held responsible for consequences resulting from such differences.
Environmental Considerations:
California Environmental Quality Act (CEQA): The Community Development Department, Environmental Planning Services Division determined the Old Sacramento Infrastructure Project (C13000730) would not have a significant impact to the environment. Therefore, a Mitigated Negative Declaration was prepared in compliance with Section 15070(b)(1) of the California Environmental Quality Act (CEQA) Guidelines and adopted by City Council on May 23, 2017.
The Mitigated Negative Declaration was available for Public Review during the period of January 5, 2016, through February 4, 2016. The Mitigated Negative Declaration, Mitigated Reporting Plan, and attachments are available on the City’s Community Development Department Environmental Impact Report webpage at:

Sustainability: Not applicable
Commission/Committee Action: None
Rationale for Recommendation: Change Order No. 6 to Contract No. 2015-0029 with Unger Construction Company, in the amount not to exceed $270,305 is necessary to complete and close out the project to include the costs for the additional scope of work encountered during construction related to the unforeseen site conditions, necessary building structure improvements, and other design modifications.
Financial Considerations: Sufficient funding is available in the Old Sacramento Infrastructure Project (C13000730) in the General Fund (Fund 1001) to execute Change Order No. 6 to Contract 2015-0029 in the amount of $270,305.
Local Business Enterprise (LBE): Unger Construction Company is an LBE.
Background: On May 14, 2013, City Council approved the Old Sacramento Infrastructure
Project to repair and renovate the boardwalk along the waterfront and the K Street Barge. On
March 18, 2014, City Council adopted Resolution No. 2014-0070 suspending competitive
bidding to utilize the design-build project delivery approach. On January 13, 2015 City Council
authorized the City Manager to execute a design-build contract with Unger Construction Company in the not-to-exceed amount of $722,244 to design the boardwalk and barge renovation projects.
On November 2, 2015, City Council authorized the City Manager or the City Manager’s
designee to execute Supplemental Agreement No. 1 to Contract No. 2015-0029 with Unger
Construction Co. in the amount of $72,000 to provide compensation for preliminary designs
related to the riverfront bike trail, new electrical services, additional stakeholder outreach, and design issues not included in the original contract.
On October 18, 2016, City Council passed Motion No. 2016-0315 authorizing the City Manager
or the City Manager’s designee to execute Supplemental Agreement No. 2 to Contract No.
2015-0029 with Unger Construction Co. in the amount of $48,914 to provide compensation for
design changes related to the K Street valet area, on-street parking revisions, L
Street crosswalk, additional meetings, and other refinements that were not provided for in the
original contract.
On May 23, 2017, City Council passed Resolution No. 2017-0192 authorizing the City Manager to execute Change Order No. 3 initiating the construction phase and increasing the contract amount by $7,745,774, and ratifying Change Order Nos. 1 and 2.
Change Order Nos. 4 and 5 were for extension of time. Change Order No. 6 to Contract No. 2015-0029 with Unger Construction Co. in an amount not to exceed $270,305 is necessary to close out the Old Sacramento Infrastructure Project (C13000730).
