A RESOLUTION OF THE MAYOR AND CITY COMMISSION OF THE CITY OF MIAMI BEACH, FLORIDA, APPROVING AND AUTHORIZING THE MAYOR AND CITY CLERK TO EXECUTE AMENDMENT NO. 1 TO THE PROFESSIONAL SERVICE AGREEMENT BETWEEN THE CITY AND WADE TRIM INC., PURSUANT TO RFQ NO. 2017-003-KB, FOR ARCHITECTURAL AND ENGINEERING DESIGN SERVICES FOR THE 1ST STREET (ALTON ROAD TO WASHINGTON AVENUE) PROJECT, IN THE NOT TO EXCEED AMOUNT OF $618,801, TO 1) DEVELOP A HYDRAULIC MODEL USING THE CITY'S 10-YEAR, 24-HOUR STORM EVENT, 2) INCORPORATE THE RESULTS OF THE HYDRAULIC MODEL AS PART OF THE DESIGN DOCUMENTS FOR THE PROJECT, AND 3) CONTINUE THE COORDINATION EFFORTS FOR THE SELECTION OF THE APPROPRIATE ROADWAY CROSS SECTION AND THE LOCATION OF THE PUMP STATION AND OUTFALL, FOR A TOTAL PROJECT DESIGN COST OF $1,873,100.

On March 1, 2017, the Mayor and City Commission approved Resolution No. 2017-29759, accepting the recommendation of the City Manager, pursuant to Request for Qualifications (RFQ) No. 2017-003-KB for Architectural and Engineering Design Services for the 1st Street (Alton Road to Washington Avenue) Project, and to enter into negotiations with Wade Trim Inc., as the top ranked proposer.

On June 16, 2017, the City and Wade Trim Inc. executed an agreement to perform design, permitting and construction services for the 1st Street road and drainage improvements between Washington Avenue and Alton Road, including the design of the drainage trunk lines along Alton Road and Washington Avenue, between Fifth Street and South Point Drive.

The design was based on the hydraulic model for the South Pointe Neighborhood project developed by AECOM as part of the stormwater program, which included pipe and pump station size based on the design storm event of a 5-year, 24-hour rain event.

The design included a fixed location of the pump station at the triangular park at the southeast corner of 1st Street and Alton Road, and an outfall to the Marina along an 80 foot utility easement held by the City at the main entrance of the Murano at the Portofino property.

In the past two years, Wade Trim Inc. and City staff have coordinated with residents and project stakeholders to develop a consensus on an appropriate typical section along 1st Street. Project stakeholders have requested that the City evaluate other potential options for the location of the pump station and outfall.  The project is in the preliminary design stage and will proceed to the final design stage once the proposed roadway cross section, location of the pump station and its outfall are selected.

On October 18, 2017, the City Commission adopted Resolution 2017-30039, to increase the design storm event from a 5 year, 24 hour duration to a 10 year, 24 hour duration. Due to the aforementioned change, the City requested Wade Trim Inc. to provide a proposal to perform the following additional tasks not included in the original scope of services:

   a. Develop a hydraulic model using the 10-year, 24-hour storm event for the post and pre development conditions and take ownership of the model;
    b. Incorporate the results of the hydraulic model which is expected to substantially increase the size of the pump station and the major trunk lines along Alton Road, Washington Avenue and 1st Street;
    c. Continue the coordination efforts for the selection of the appropriate roadway cross section, as well as the location of the pump station and its outfall.

Following several weeks of negotiations, City staff and Wade Trim Inc. have reached a reasonable and fair fee for the aforementioned scope in the amount of $618,801 for a total project cost of $1,873,100.
