Several changes to the Contract appear warranted, and we are requesting that you consider these changes and recommend approval by the City The changes are explained in the next paragraphs. The specifications require that the computer workstations include a maintenance program that is linked to the SCADA system. This package is not very sophisticated, but does provide some maintenance functions. Between the time the project was bid and US Filter was prepanng to order the package, the manufacturer announced that they were discontinuing the program and were replacing it with a more expensive program that has additional features. The maintenance package originally specified cost $500, while the replacement program costs about $1,300. hi discussions with the City staff, we concluded that the maintenance information could be obtained using other means and that the maintenance program would be deleted from the project. A deduct of $500 is recommended. The specifications require telephone dialers to notify the staff at night and when the office is not staffed. The dialers specified did not have the capability to allow for different "lists" of callout names. The City staff requested dialers with the capability of multiple "lists A dialer was identified with this feature, but the cost is an additional $530. A change order amount of $530 is recommended. The path study completed on behalf of the City recommended the use of /s" coaxial antenna cable. As US Filter was confirming the results of the path study, they concluded that the reduced losses provided by r /e" coaxial cable would result in improved communication between the various sites We agree with their conclusion The added cost of the Heliax coaxial antenna cable is $1,040, and a change order for that amount is recommended When the project was designed and bid, the Glendalough lift station had not been designed and there was no requirement to include it in the SCADA system. US Filter has proposed a cost of $3,400 to configure the Glendalough lift station into the SCADA system, including screen development and local configuration of the remote. This change order item is recommended. City of Rosemount Attn: Mr. Andy Brotzler May 4, 2005 Revised Page 2 The SCADA system is configured to "connect" existing wells, towers and lift stations into the system without rehabilitating or reconditioning the equipment in the stations The reason was to construct a supervisory control and data acquisition system without also including rehabilitation of wellhouses, elevated storage tanks, etc However, dunng the project meetings, it has become evident that operation of the water system would benefit if several improvements were incorporated into the system that were not onginally included. Those features include the furnishing and installation of flow meters for wells RR1 and RR2 on the east side of town. The work would also include a new transmitter so the flow meter at well #8 could be included in the SCADA system to provide flow rates, total flow, and related information not available with the existmg equipment. US Filter has provided a quotation of $13,601 for this work, including the cable and conduit, configuration of the displays and reports, and the new meter heads and transmitters. Since this benefits system operation, we recommend that the City approve this change order request. At Wensmann Pond, a radio antenna is required near the control panel at the south side of the pond. The poles that are preferred and were specified for the system are dark bronze metal poles. This requires the use of a truck to auger in the pole bases, and damage to the lawns (particularly dunng wet weather) is a concern at this station due to limited access. The homeowners would be inconvenienced, and significant restoration might be required. An option is to install a fiberglass pole that can be installed using handheld equipment. The fiberglass pole can be procured and installed for an additional $525 This change order item is recommended. In summary, the following items are recommended: Dialers capable of multiple "lists" 530 Wensmann Pond pole 525 RR1 /RR2/ Well 8 flow meter 13,601 Coaxial cable 1,040 Glendalough Lift Station incorporation 3,400 Maintenance Program 500 TOTAL 18,596 The changes and modifications are recommended. Please note that US Filter has requested a six week extension of the contract for these changes and modifications. The extension is also recommended. In a related matter, the specification for the project requires a $20,000 allowance for computers and associated hardware The allowance is to be adjusted based on actual project needs. At this time, the allowance shows a balance of $14,989.70. As the project gets close to completion, a change order will be initiated to deduct the outstanding balance from the Contract. City of Rosemount Attn. Mr. Andy Brotzler May 4, 2005 Revised Page 3 We trust this information and the enclosures from US Filter will allow a decision regarding these change order items. If the change order is approved, we'll commence with the formal change order, including an extension for completion of the project based on City approval since the material cannot be ordered until the change order is approved, if that is the decision reached by the City. For your information, the following project status is provided. Original Contract Amount 371,427 Amount proposed in this request 18,596 New Contract Amount 390,023 If you require additional information, please contact me. Thank you.
