Subject Allison WWTP Mechanical Bar Screen and Got Removal Improvements
City Protect No.7417
Dear Natasha:
The scope of the subject project included cleaning out and refurbishing the existing
aeration system in the West Aeration Basins. The existing East Aeration Basins are also in
need of cleaning out and refurbishment. The existing E.Aeration Basins have not been cleaned
out since the basins were put into service in 1985 and there are obvious issues with the aeration
system. The air system is used to add oxygen to the biological process and keep the solids in
suspension. There are missing air drop pipes and loose air drop pipes throughout the basins. It
is likely, based on what was found at the W. Aeration Basins, that the existing air drop lower
support systems need to be replaced. We recommend that the existing E. Aeration Basins be
taken out of service and completely cleaned out of settled grit, debris, rags, eta and that the
existing air drop aeration system be refurbished by replacing missing air drops, replacing
damaged air drops and replacing the lower support system.
Other additional work that has been added to the scope of the project is listed in
the following:
1. 16" Dia. Pipe Replacement(Change Order No. 2): The existing 16' D.I. pipe between the
Grit Removal Unit and West Aeration Basins was found to be severely corroded in the top
and needed to be replaced when uncovered for installation of the new 24"dia.force main.
2. Existing 24" valve replacement (Change Order No. 3): The existing 24" plug valve on the
force main that feeds the Existing Grit Removal Unit was open and either inoperable or
broke when the Plant Operator's tried to close it to redirect flow to the new Mechanical Bar
Screen Facility. This valve is critical to the operation of the plant and needs to be operable
in order to re-direct flow from the Grit Removal Unit to the New Mech. Bar Screen Facility.
3. Grit Removal Weir Replacement(Change Order No. 3): The original scope did not call for
the replacement of the two discharge weirs but, after the unit had been drained, they were
found to be in very bad shape and were replaced.
4. New Electrical Receptacles (Change Order No. 3): Plant staff requested that two duplex
receptacles be located on the upper bar screen level to provide a dedicated circuit for the
plant's raw influent sample which they would like to locate in this area.
5. Mech. Bar Screen Wider Entrance Driveway: During construction Plant staff requested that
the driveway entrance to the debris containers be made wider to provide more space for the
City's hook truck to back up and pick up the containers instead of pulling the containers out
to the parking area. The cost to make the driveway wider was minor at$4759 due to 5%
extra provide with the bid quantities but it did require revising/redrawing of Sheet 4 of the
Plans to show the dimensional changes and revisions to the pavement grades.

A summary of the costs of the additional work added or work proposed to be added to
the construction contract Is provided in the following:
CO#2: W.Aeration Basin Influent Pipe Replacement $ 15,108
CO#3: Grit Removal 24"Valve and Pipe Replacement $ 89,725
CON: Grit Removal Weir and New Electrical Receptacle $ 7,614
CO#4: Mech.Bar Screen wider driveway(additional quantities) $ 4,759
CO#4: E.Aeration Basin Cleanout and Air System Refurbish(Est.) $263.400
Total Additional Construction Cost $380,806
Attached is a summary of change orders to date and pending additional ems of work.
This summary does not include the E. Aeration Basin work. Pending additional work items
include final quantities used for missing air drops and clamps in the W. Aeration Basins and
large quantity of grit found in the existing Grit Removal Unit. The Grit Removal Unit has
apparently been out of service for some time and the grit found and removed by the Contractor
was over twice what was noted in the unit when it had been drained during the design phase in
2009. Based on the attached summary there should be approximately $450,000 of change
order capacity left in the project This is more than enough to fund the change order for work at
the E.Aeration Basins.
The additional engineering services required for the additional work items include initial
investigation, located original equipment drawings, develop scope and plans, contacting the
Contractor concerning the additional work, negotiating and preparing change order, submittal
review, answering Contractor questions, checking progress, punch lists and checking
completion.
We request that our present AE contract be amended by$26,800 to add the engineering
services to accomplish this additional work. Please review and let me know should you have
any questions or comments.
Sincerely,
URBAN ENGINEERING
