EXECUTIVE SUMMARY
PROJECT: Chicago Ditch Dam Rehabilitation
2
Proposal No. 2. Construct the replacement intake control structure
at the same location as the original intake structure. Use of this
approach is expected to produce desired value added features
(avoiding flooding issues, potential risk of structure movement
necessitating replacement, etcetera) and had the potential to reduce
costs by about $95,100.
Proposal No. 3. Install automation equipment to control gates and
measure flows. The Value Study Team estimated that this approach
would produce several desired value added features (avoiding
expertise, production losses, potential risk to staff, etcetera).
However, it had the potential to increase costs by about $13,700 over
the life of the diversion facilities.
Proposal No. 4. Use precast units to construct gate floor, walls,
and support blocks. It was estimated that this approach would produce
several desired value added features (reducing lost water diversion
time, construction time, and removing gate associated seasonal
requirements) and had the potential to reduce costs by about $5,800.
Assuming the maximum cost savings for proposals that are independent of each
other were selected, the maximum potential saving for the independent
proposals resulting from the value study was about $653,000 (pursuant to Part
IV of the Interior Office of Management and Budget Fiscal Year report for
FY97.) The cost to perform the value study was less than $20,000.
Additional Items for Further Study.
More than ten additional items for further study were also recommended. These
are items that, due to time constraints, the lack of apparent large
significant savings or value added during initial idea evaluations,
complexity of idea, or scope of the idea (as compared to the study scope),
make further investigation by the Value Study Team, within their limited time
constraints, inadvisable. They are submitted for further consideration and
development to add value for the project. The Value Study Team did not
develop these concepts to the detail of the previous alternative proposals.
