Title
Grasslands Subdivision Water Main Connection - Proposal
History
This year’s approved budget included connecting the dead end water mains between the Grasslands subdivision and the Brook Hills subdivision. Currently there is a single domestic water source servicing the Grasslands subdivision. This connection will provide a secondary source for the area and eliminate two existing dead-end water mains. Gallagher and Henry own the property and has agreed to allow the installation. A plat of easement for the watermain is needed for the construction and maintenance of the water main on the property which is currently being farmed.
The Public Works Department reviewed two methods for completing the work. Proposals were obtained to evaluate the two methods. The first method followed the traditional design, bid, construction, sequence. A proposal for design, bid documents, permitting and platting was obtained from HR Green in the amount of $9,975. A construction proposal from Airy’s Inc. totaled $34,504. The total cost using this method is estimated to be $44,479.
The second method, Design-Build, has the benefit of a significantly reduced timeframe, lower engineering costs and strong contractor commitment. It is currently being used for the Watermain Replacement Project in Orland Hills Garden and Old Orland (near Ravinia Avenue and 144th Place). This work is being performed by Austin-Tyler Construction, LLC of Elwood, Illinois. A proposal was requested from Austin-Tyler for design, permitting, platting and construction of the Grasslands Water Main Connection. The proposal was provided at $39,600. Staff recommends advancing this project using Austin-Tyler for a Design-Build project.
