1b1. Country Suites Contract Amendment lb - ir CITY OF CHANHASSEN 0- 114? 690 COULTER DRIVE • P.O. BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937-1900 • FAX (612) 937-5739 MEMORANDUM z- s. TO: Don Ashworth, City Manager ' FROM: Gary Warren , City Engineer DATE: October 3 , 1990 SUBJ: Approve Contract Amendment No. 2 for Country Hospitality Suites Improvement Project No. 89-25 By the nature of the beast , the Country Hospitality Suites Y ► Y F Y improvement project has been fraught with coordination challenges and changes . Working on a site improvement of this nature with the time constraints imposed by the lending agencies has resulted in a lot of lost hair on the parts of all parties involved. The attached Contract Amendment No. 2 provides a synopsis of necessary scope adjustments which were undertaken as the project ' progressed. The attached October 1 , 1990 correspondence from BRW accurately summarizes the necessary change elements. Fortunately in this regard the net change to the contract is a deduct of $3 ,940 . 06 . This is due largely to the $24,000 savings which resulted from the decision to use restrained joints on the watermain rather than ball-joint pipe . I find the attached Contract Amendment No. 2 in order and therefore recommend approval and establishing a revised contract ceiling amount of $320,097 . 89 . ' ktm Attachments : 1.

I C.P. 89-25 CONTRACT AMENDMENT NUMBER TWO IDear Mr. Warren: Please find enclosed six copies of Contract Amendment Number Two for the above referenced project for your approval . The amendment has been prepared to include IInew bid items and revis-ed contract quantities as required by the following modifications to the project: IIA. Watermain Repair — Dinner Theatre The plans and specifications specified the installation of Ball Joint I Watermain pipe to address concerns about the stability of the fill area where the watermain was to be constructed. Subsequent to receipt of bids, we reviewed the cost of Ball Joint Pipe, the site, and discussed this ' further with the contractor. It was our conclusion that restrained joint watermain was a more cost effective solution for this installation and we directed the contractor to proceed with the installation of restrained 1 joint rather that Ball Joint Pipe. B. Subgrade Correction — Country Suites Hotel ISite preparation and subgrade correction were the responsibility of the developer prior to the construction of the Parking Lot Base by this I contractor. However, this work was not completed by the developer. They requested that this work be completed by the City contractor in order to save time and to allow improved coordination of the work. IAt the request of the developer and your direction we directed the contractor to proceed with subgrade excavation and the restoration to 1 subgrade utilizing Geotextile Fabric and extra depth aggregate base as summarized by Item Number Two of Contract Amendment Number Two.

The Contractor has installed field lok gasket ductile iron pipe in substi- tution for the ductile iron ball joint pipe originally specified for the water main repair-work east of the Country Hospitality Suites site.
