COUNCIL REPORT

REGULAR COUNCIL

Subject: Award of Design-Build Contract - Clayburn Road Bridge Replacement

RECOMMENDATIONS

1. THAT the Design-Build Contract for Clayburn Road Bridge Replacement, be awarded to Cewe Infrastructure Ltd., in the amount of 955,000, plus GST;

2. THAT the Lower Sumas Mountain Road Culvert Replacement be deferred for consideration with the 2016 Capital budget and the funds be reallocated to Clayburn Road Bridge Replacement; and

3. THAT the Mayor and Corporate Officer be authorized to execute all documents related to this matter.

SUMMARY OF THE ISSUE

RFP 2015-09 - Clayburn Road Bridge Replacement and Lower Sumas Mountain Road (LSMR) Culvert Replacement, closed on June 26, 2015. The proposals submitted by the three pre­selected design/build contractors came in above the available 2015 budget. At City's solicitors' advice, RFP 2015-09 was cancelled and staff requested the proponents to provide a price and design for the Clayburn Road Bridge Replacement only. Based on the prices received and after completing the design review, it is recommended to award the Clayburn Road Bridge Replacement design-build contract to Cewe Infrastructure Ltd., in the amount of $955,000, plus GST.

BACKGROUND

Request for Qualification (RFQ) 2015-01 was advertised on BC Bid. Five proponents submitted proposals. Three proponents met the requirements of the RFQ and were invited to participate in Request for Proposal (RFP) 2015-09.

At closing date, June 26, 2015, the three proponents submitted a lump sum price and design. The results were:

Company Lump Sum Price (excluding GST)

Martens Asphalt Ltd $1,447,737.55 B&B Heavy Civil Construction Ltd. $1 ,886,000.00 Cewe Infrastructure Ltd. $1 ,989,000.00

Report No. ENG 059-2015 Page 2 of 3

As the RFP is evaluated on design and price and all three prices came in above the $1M budget, the City solicitor advised that the RFP be cancelled and securities be returned.

The Clayburn Road Bridge Replacement is considered a higher priority than the LSMR Culvert Replacement. To stay within the available budget, the three proponents were requested to review their designs to comply with the minimum height and throughput volume requirements and to provide a lump sum price for the Clayburn Road Bridge Replacement only. All three proponents were given the choice to partake, and should they prefer not to participate, there would be no penalties. The closing date for the revised submission was July 15, 2015.

The designs were reviewed by staff and an independent consultant, Justin Pedley from Core Project Management. The preferred proponent is Cewe Infrastructure Ltd. (Cewe) and is recommended for award.

DISCUSSION

The results of the design review are summarized below:

Description CEWE Martens B&B Type of structure Concrete box girders Concrete box girders Concrete box girders Sub-Structure 2x6x610mm steel 2x3x457 steel piles SierraScape retaining

piles structure Bridge Soffit Elevation 4.6m 4.6m 4.6m Throughput area 42m2 42m2 42m2

Cewe's design/price is considered to be the best value to the City. Cewe's design includes a structural life expectancy of 75 years with 100 years for items subjected to corrosion. The design requires minimal maintenance as there are no expansion joints and no bearing pads. The concrete box girders proposed for the bridge are pre-stressed and with the pile design, comply with the CSA-56-14 bridge design code, BCL 625 dynamic loading requirements and CSA-56-14 seismic requirements. The cross-section for the bridge will include 2 x 3.5m travel lanes, 2 x 1.5m bike lanes/paved shoulder and a 1.5m wide sidewalk. The typical cross-sections are attached as Appendix A. Cewe will prepare an Environmental Management Plan during construction to ensure that all environmental requirements are met. Clayburn Road will be closed for through traffic during construction. Notification of the closure will be advertised on the City website and in the local newspaper. Cewe proposed the shortest schedule of 50 working days.

ISL Engineering Ltd. (ISL) will be the prime engineering consultant for Cewe. ISL is a reputable multidisciplinary engineering firm that successfully completed many large City projects, including
