Memorandum

To:Honorable Mayor and Town Council
From:Alex Rey, Town Manager
Subject:Award of a Work Order for Design and Construction Administration for NW 67th Avenue Widening Project
Date:3/7/2017

Recommendation:
It is recommended that the Town Council authorize the Town Manager to execute a work order under an existing contract for miscellaneous engineering services, contract 2012-04ME, in the amount of $148,000 which includes a base amount of $134,482 plus a $13,518 contingency to Marlin Engineering, which is the consulting firm that worked on the conceptual design feasibility study for the NW 67th Avenue Widening Project. The work order includes design, permitting, and construction administration. Funding in the amount of $411,415 from the Capital Projects Fund is designated for the NW 67th Avenue and Windmill Gate Road Improvement Projects in Fiscal Year 2016-2017.
Background:

At the Town Council's October 6, 2015 meeting, resolution 15-1330 was passed adopting 23 strategies to address transportation issues facing the Town. One of the strategies identified was the widening of NW 67th Avenue to add an additional through lane on the northbound approach near the Palmetto Expressway intersection. The goal of this project is to help alleviate peak hour congestion in this area.

Earlier last year the Town issued a work order to Marlin Engineering to perform a design feasibility study, which consisted of studying and developing concept alternatives for the northbound through lane on the southern approach to the intersection at NW 67th Avenue and NW 167th Street. The recommendation adds an additional through lane by taking away part of the median from approximately 77 ft. south of Windmill Gate Road to NW 167th Street and reducing the width of the travel lanes. Thisalternativedoes not require the purchase of additional right of way and added the most capacity compared to the other two proposed alternatives. The improvements for NW 67th Avenue will extend from approximately 300 ft.


south of Windmill Gate Road up to NW 167th Street and will include:

  • Removing a portion of the existing median 77 ft. south of Windmill Gate Road to NW 167th Street to accommodate the additional through lane
  • Milling and Resurfacing of the northbound portion of NW 67th Avenue approximately 300 ft. south of the Windmill Gate Road intersection to NW 167th Street
  • Upgrading the traffic signal at the Windmill Gate intersection from span wires to mast arms and including pedestrian countdown features at this intersection
  • Modifying the existing traffic signal at NW 167th Street intersection to include a three section head on the upright to control right turn movements

The work to be completed by Marlin Engineering under this work order will include pre-design services and testing, surveying, roadway analysis, design plans, permitting assistance, and construction administration for this project. As part of this work order, Marlin Engineering will also be doing construction administration for the Windmill Gate Road project. Improvements to Windmill Gate Road will include the widening the road to include an additional through lane going east bound. It was determined since both projects are in close proximity; the Town should have one firm overseeing the construction administration, since both projects are expected to be constructed together under one contract.

The total amount for this work order is $134,482.00 plus a contingency in the amount of $13,518 for unforeseen conditions or circumstances.

Alternatively, we are exploring using the transportation impact fee credit for the design and construction of this projects.
