Dear Mr. Rakesh Chaubey:
This memo is to clarify the reasons why the original re-plumbing of service for Lots 11 A& 12A
Block 123 of the Original City of fort Worth was unsuccessful. Based upon the landowner and City
policy, as expressed by the City Staff, the original design was directed toward minimizing parking
obstruction to the business on the subject property. This excluded designing a service across the existing
parking lot to the proposed manhole 2+53 M4-B in Cummings street, which had a gravel surface at the
time of design. Here are additional reasons to the original design:
• Pre-Design and Pre-Construction could not televise L-1904 to locate the functioning service
line for the structure on subject property.
• A manhole only labeled as MH 6 near the center of Block 123 could not be located by City
services,television inspection, or our firm.
• A uniform slope was interpolated from the 2 known manholes on L-1904 being 515 feet
apart. Combined with the distance, missing manhole and inability to televise L-1904 a true
slope and depth for the existing service could not be known until construction began.
• Due to a 24"water main being out of position as reported on City of Fort Worth as-built
sheets, the original designed was compromised. The new manhole invert position,in the
intersection of Bluff and Pecan streets is at least a foot higher than designed.
• The service route to manhole 27+64 in Pecan Street could have been achieved with a 1%
slope on the 4" service and lowering the manhole invert to 609.78 resulting in a 0.5%slope to
the new manhole position in the intersection of Bluff St. and Pecan St.
Based upon these facts, it is our contention that the change in design was the result of changes in data that
was not available at the time of original design. We therefore request and additional amendment to
increase the contract amount by$1,197.15 to provide for additional services.
