The Farm Development Project is currently under construction and The Avenue is planned to begin construction in FY21. Both developments reside along Alma Drive north of Ridgeview Drive. These abutting developments require adding two lanes to the outside of Alma Drive (north of Ridgeview Drive), as has been intended to finish the roadway. The Farm Development will also have a direct impact to Ridgeview Drive specifically requiring the need for two westbound lanes on Ridgeview Drive from Watters Branch Creek to Alma Drive. The proposed lanes on Alma Drive and Ridgeview Drive will accommodate the anticipated traffic volume increase on both roadways. At project completion, Alma Drive will be a six-lane divided roadway and Ridgeview Drive will be four-lane divided roadway.
Both roadways are identified on the City's Master Thoroughfare Plan as well as Collin County's Master Thoroughfare Plans as eventually being six-lane divided roadways in the final build-out condition.
This project was bid with alternates for the ease of funding source allocation. Staff recommends awarding the base bid with all alternates, described below. By awarding these alternates with the base bid, the City will achieve cost saving through economy of scale and a single mobilization fee. There will also be valuable time savings by allowing our chosen contactor to complete all the work at once as well future traffic impacts with smaller separate construction projects.
Base Bid: Includes the cost of construction for the additional northbound and southbound lanes of Alma Drive, and the westbound lanes on Ridgeview Drive. Drainage infrastructure will also be built with the base Bid.
Alternate 1: Includes the cost of construction for right and left turn lanes into the future Farm development. The Developers of the Farm will provide reimbursement the cost of the right turn lanes into their development, in accordance with the approved Development Agreement, in the amount of $194,481.97.
Alternate 2: Includes the cost of installing LED roadway illumination within the median of Ridgeview Drive.
Alternate 3: Includes the cost of upgrading the traffic signal infrastructure. With the additional lanes at the intersection of Alma and Ridgeview Drives signal improvements are required to bring the existing signal up to industry standards and will also provide ADA compliance at the intersection.
Alternate 4: Includes the cost of construction for the dedicated right turn lane for southbound Alma Drive to westbound Exchange Parkway. This also includes sidewalk, ramp and pedestrian pole relocations necessary.

This project was competitively bid and publicly advertised, with terms for selection based on "best value". Upon review of the price proposals, reference checks, past work experience of each bidder, and the time of completion bid on the project it is recommended to award the contract to Ed Bell Construction Company. Time savings were considered due to an expected increase in demand for developments nearing completion in McKinney and the future developments in Allen. This allows for less construction related delays for the traveling public. Time savings for each bidder was calculated by adding the value of a calendar day to the proposed bid. Bids were normalized in the attached Normalized Bid Evaluation Chart to show the lowest bidder, when considering time for completion as well as absolute price. The value of each day saved was estimated to be $1,500 in value added to any bid with greater time proposed for completion. After evaluating the complete bid packages in this manner, Ed Bell Construction Company represents the best value.
