Quantity Increase: <br /> <br />Background: Upon review of our project files and in discussing the additional quantities <br />and costs with office staff who calculated the modular block wail, the following history <br />has been extrapolated to the best of everybody's knowledge. Originally the modular <br />block wall was separated for bid by structural wall and the turtle wall and then combined <br />into one quantity by State-Aid direction. However, the deficiency bettween the modular <br />block quantity included in the Bid Form and in the quantity, required by the approved <br />plans most likely occurred because the buried portion of the modular bloCk wall was not <br />included in the hid calculations. The project specifications state that below and above <br />ground modular block wall will be included for payment. In general, this means that at <br />the Turtle Wall approximately one (1) foot of bury depth was not included in the bid <br />calculations along with deeper block buried at higher wall locations, which were <br />included. A rough calculation indicat~-~that there is approximatel, y 3,500 feet of total <br />modular wall. A majority of the modular block overrun from the Bid Form quantity <br />would be attributed to not including the bury depth along the len~h of the Wall in the Bid <br />Form. The Bid Form quantity for project modular block walls is 6,845 sf versus the <br />actual installed quantity of 11,225 sf. <br /> <br />G;\Meadota Heights Production\Cliems\Rmn. ey\99-__ -s\Cor~espoadence\200lklankowski Ltr 8-7-01 .doc <br /> <br /> Offices: Hibbing · Minnetonka · St. Paul .
