Consider change order for engineering services related to City project #08-21; water tower #3

Council awarded a contract for engineering services on water tower #3 to Progressive Consulting Engineers (PCE), in an amount not to exceed $169,330, on April 22, 2008.  During implementation of the project the tower location moved twice.  Initially it was to be located in Elmcrest Park, but due to poor soil conditions an alternative location was investigated, chosen, and acquired.  This move occurred during production of the preliminary design report, and water distribution modeling, site analysis, and report updates were required, resulting in an amended scope with an increased budget of $5,000.  Following final approval of the project and award of a construction contract the tower moved again within the newly acquired site, for which a change order was processed and approved by Council on July 28, 2009.  At that time PCE requested an additional $5,000 for further revisions to the plans, but staff recommended delaying such action until the project was closer to completion to see if cost savings could be realized throughout the construction process.  The project is now substantially complete, and while some savings were realized PCE has requested additional compensation in the amount of $2,700 to cover revisions associated with the tower relocation.  The 2 scope revisions outlined above results in a total contract increase in the amount of $7,700.

At the time of approval of this project Council provided the Director of Public Works with authority to process change orders up to a maximum of $15,000.  These scope revisions have been approved at staff level, but are being advanced to Council for formal processing.

 

The original contracted construction project was approved in the amount of $3,188,400, and with change orders has increased to a final cost of $3,225,553.  The approved change orders are as follows:

Staff recommends approval of a change order to the PCE contract in the amount of $7,700 for required project revisions outside of the original scope.  It is further recommended to approve a change order to the Chicago Bridge & Iron (CB&I) contract in the amount of $14,276 for required construction revisions.

Motion to approve the change orders.
