Description/Analysis
Issue Detail: The outdoor dining deck overlooking the Sacramento River, located at 1110 Front Street in Old Sacramento (formerly leased to the Rio City Café), was deemed unsafe and in need of replacement. A local Engineering firm, Lionakis, was retained to evaluate the deck in 2019. Based on the results of their study, they recommended a complete deck replacement using wood timber and structural steel. In August of 2022, the City Council approved Motion No. 2022-0288 suspending competitive bidding to allow the use of a design-assist approach to construction based on the complexity of removing and replacing the deck located over the Sacramento River.

File ID: 2025-00727 3/25/2025 Discussion Item 20.

A Request for Qualifications, Q22014541002, was issued on September 14, 2022, soliciting Design Assist Contractors for the demolition and construction of a new deck. Only one contractor, Traimid Construction of Central California, Inc. (Triamid), submitted a proposal. After reviewing the proposal, and an interview, they were chosen as the Design Assist Contractor. Lionakis in collaboration with Triamid have completed the design and are prepared to enter the construction phase. Because the work must be completed over the Sacramento River, the allowable construction window is from May 1 to October 31 of each calendar year. Staff is targeting May of 2025 to begin work and complete it by the end of October 2025.

Policy Considerations: The recommendations in this report are in accordance with the provisions of City Code Chapter 3.56.090 requiring City Council approval for agreements equal to or greater than $250,000.

Sacramento City Code Section 4.04.020 and the City Council Rules of Procedure (Chapter 7, Section E.2.d) require that unless waived by 2/3 vote of the City Council, all contracts and labor agreements great than $1,000,000 shall be made available to the public at least ten (10) days prior to Council action. This item was published for 10-day review on March 14, 2025, in compliance with the City Code.

Economic Impacts: The recommended contract is expected to create 21.41 jobs (13.60 direct jobs and 7.81 jobs through indirect and induced activities) and create $2,825,492 in total economic output ($1,811,214 of direct output and another $1,014,278 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 impact 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 action is exempt from review under the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines section 15301. Required maintenance and rehabilitation of existing serviceable deck and structure and part of existing building with no expansion of existing use.

Sustainability: Not applicable
Commission/Committee Action: Not applicable
Rationale for Recommendation: Lionakis in collaboration with Triamid have completed the design for a new deck. Triamid has developed a Guaranteed Maximum Price (GMP) based on the final deck

File ID: 2025-00727 3/25/2025 Discussion Item 20.
design. Staff recommend accepting the GMP and executing Contract Supplement No. 1 to City Agreement No. 2023-0918 with Triamid in the not-to-exceed amount by $2,893,424 for a new total not-to-exceed amount of $3,073,352; and increasing the City Manager’s change order authority to six percent ($184,401) of the new not-to-exceed amount of $3,073,352 for the construction of the deck.

Financial Considerations: The costs for reconstruction of the new deck are estimated at $3,073,352 in contract costs. In addition, the City may incur construction management and other administrative costs as the project progresses.

The City has been awarded approximately $4.6 million in grant funds from the State of California for Riverfront safety and pedestrian improvements. These funds will be allocated to the Old Sac Revitalization and Improvement Project (C15002100) to restore the deck, and these improvements will create a safer environment for the community.

Local Business Enterprise (LBE): Trimid Construction of Central California, Inc. is an LBE.

Cast-In-Place Concrete January 26, 2024

B. Add no water during delivery and at the project site unless spe cifically accepted by Architect. If water is withheld at batch plant, indicate in delivery ticket the design water for accepted mix, moisture content of aggregates, and free water added at batch plant. If total water added at plant is less than design water to attain slump of accepted mix design, water may be added to concrete at job site, not to exceed the design water content , subject to the limitations specified in ASTM C94/C94M. If additional slump is required, use water reducing admixture.

C. Discharge mixed concrete within 1 -1/2 hours after the introduction of mixing water to the cement and aggregates. Reduce this time to 45 minutes when the concrete temperature exceeds 85 degrees F , unless appropriate measures as specified in ACI SPEC-305.1 are taken to maintain slump and temperature of concrete . Slump and concrete temperature can be maintained within limits longer with the use of retarding admixtures or hydration -control admixtures.

D. Place concrete within fifteen minutes after it ha s been discharged from the mixer. Handle concrete from mixer to forms in a continuous manner.

E. Deposit concrete as close as possible to its final position in the forms, with no vertical drop greater than five feet except where suitable equipment is provided to prevent segregation and where specifically authorized.

F. Deposit concrete continuously or in layers of such thickness that no new concrete will be placed on concrete that has hardened enough to cause seams or planes of weakness. If concrete cannot be pla ced continuously, provide construction joints as specified. Deposit concrete to avoid segregation.

G. Deposit concrete in forms in horizontal layers no deeper than 24 inches and in a manner to avoid inclined construction joints. Place each layer while precedi ng layer is still plastic to avoid cold joints.

H. Pumping concrete, when specifically accepted, may be conveyed by positive displacement pump such as pi ston or squeeze pressure type; pneumatic placing equipment is not permitted. Use rigid steel pipe or heavy -duty flexible hose with an inside diameter at least three times the nominal maximum -size coarse aggregate, but not less than 4 inches.

Aluminum pipe is not allowed.

I. Provide adequate scaffolding, ramps and walkways in a manner so that personnel and equipment are not supported by in-place reinforcement.

J. Consolidation: Consolidate placed concrete with mechanical vi brating equipment per ACI SPEC-301.

1. Consolidate each layer of concrete immediately after placing using internal vibrators, except for slabs 4 inches thick or less.

2. Insert and withdraw vibrators vertically at uniformly spaced location no farther than the visible effectiveness of the vibrator. Hold vibrator stationary and slowly withd raw vertically while operating.

3. Do not use vibrators to transport concrete inside forms.

4. Place vibrator to rapidly penetrate placed layer and at least 6 inches into preceding layer. Do not insert vibrators into lower layers that have begun to lose plasticity. Limit vibration duration to time necessary to consolidate co ncrete and complete embedment of reinforcement and other embedded items without causing mix to segregate.

3. Screed slab surfaces with a straightedge and strike off to correct elevations.

4. Slope exterior surfaces for drainage as directed, unless otherwise shown.

L. Hot Weather Concreting: Place concrete according to ACI SPEC-305.1 and as follows:

1. Cool components before mixing to maintain concrete temperature below 85 degrees F at time of placement. Chilled mixing water or chopped ice may be used to control temperature. Calculate and include water equivalent of ice in designed water cement ratio.

2. Cover steel reinforcement with water-soaked burlap so steel temperature will not exceed ambient air temperature immediately before embedding in concrete.

3. Fog-spray forms, steel reinforcement, and subgrade just before placing concrete. Keep subgrade moisture uniform without standing water, soft spots, or dry areas.

4. Protect concrete from surface drying; moisture loss from concrete in plastic state shall be maintained below 0.1 pounds per square foot per hour. Methods may include, but are not limited to: evaporation retardant, sun shades, wind breaks, and fog misting.

M. Cold Weather Concreting: Place concrete according to ACI SPEC-306.1 and as follows:
