BACKGROUND AND DISCUSSION:
Rehabilitation of existing storm drain lines was a component of the Water Quality Flood
Protection Program. This Storm Drain Point Repair Project identified several pipes that
could not be lined due to local structural failure of the pipes. Seven specific locations
needed to be repaired or replaced.
The Project was awarded in May 2017 to G.B. Cooke, Inc. The scope of this project
consisted of replacing all existing storm drain pipes. During the construction of the
1
project, it was determined that the pipes at three locations could be lined rather than
being replaced. The decision was made to line these three pipes instead of
replacement, which resulted in some savings. As the construction went on, field
changes occurred to provide an acceptable outfall with energy dissipaters in one
location, which was not part of the original design. In another location, the existing pipe
was between two houses which created additional challenges/costs to replace the pipe.
In the last location, we could not get access to the pipe, due to lack of any easement.
The property owner did not allow us to access the pipe through his property and,
consequently, there was additional cost to finish the work by having to access the pipe
from the other end. The additional costs to finish the project exceeded the savings,
which is reflected in the executed change orders. The contractor’s work is now finished
and has been successfully reviewed for conformance to the project plans and
specifications. The total cost of the project is summarized in the following table:
