The City is seeking proposals from experienced and qualified Delaware licensed firms for entering into a three (3) year agreement to perform any engineering service agreed upon with the winner bidder. Any award of contract(s) by the City for professional engineering services would be for a three (3) year period with the City reserving the option to extend such contract(s) for two (2), additional one (1) year periods, or portions thereof, if the City determines that extending the contract(s) would be in its best interest. A successful contract award by the City does not necessarily guarantee any amount or type of engineering services as the City intends to use the selected consultant only when the City’s regular work force is unable to perform the needed engineering services. Lastly, this will be a non-exclusive contract and nothing herein shall limit the City's right to obtain proposals or services from other professionals for similar projects at any time the City so chooses.
