Explanation
This legislation modifies the existing contract with DLZ Ohio, Incorporated, for design of the Main Street Bridge over the Scioto River in the amount of $599,763.00.
The Main Street Bridge is being designed as a community landmark that will safely serve motorists and pedestrians for generations to come while providing a necessary connection to Franklinton.
The current design contract amount is $7,714,762.00. The total contract amount including this modification is $8,314,525.00. This contract modification allows the design consultant to provide construction phase services. The cost associated with the modification was established after negotiation with the design consultant on the engineering required and the timeframe necessary for these efforts. It is in the City's best interest to continue this work with the established design team because of their current knowledge of the project and the uniqueness of this type of structure.
The contractor for this project is Kokosing Construction Company, and the project is being managed by the Ohio Department of Transportation. The City of Columbus engaged the design consultant, and is responsible for all costs associated with the design contract. The current design contract included $683,700.00, out of the estimated $1,174,905.00 for construction related services. Since the beginning of the construction phase, the design consultant has put in additional effort that was not originally anticipated, but was required. This additional effort amounts to an additional $114,934.00. The costs for the additional efforts have been slightly offset by savings in other areas, and currently amount to an additional $87,646.00 over the original estimated cost.
Since this was a multi-year project, this additional money has not been needed until this time.
DLZ Ohio's contract compliance number is 31-1268980; this expires April 16, 2009.
