III. FISCAL IMPACT:
Original Contract Amount $2,058,755.17
Previously Approved Change Order Nos. 1-6 $279,969.82
Change Order No. 7 $1,087,386.60
New Agreement Total $3,426,111.59
Item Bid within cost remaining the casing 5 the changing to Due size,
"Trenchless Crossing and 24-inch Casing for Clark Rd BNSF Crossing" will be
unused. This will ultimately represent a credit in the order of $365,000. This
credit is not reflected in the Change order amount shown above. Accounting for
this future credit, the net increase in cost due to Change order No.7 is approx.
$723,000 ($664,000+TAX).
A budget amendment is not anticipated to be needed at this time.

IV. HISTORY AND FACTS BRIEF:
On May 23, 2022, Council Approved Ordinance No. 4592 which formed LID
No. 152 ordering the sanitary sewer and lift station improvements within the
Urban Growth Area Expansion East of Road 68.
To allow the project to move forward expeditiously into construction, the scope
of work was broken into four phases, each of them packaged into a set of bid
documents and treated as an individual construction contract.
Phase 1 includes six bore trench crossings and casings to be installed.
Three of them are underneath BNSF railroad, two underneath N Glade
Road, and one underneath N Railroad Avenue (In Construction). The
proposed change order relates to this phase.
Phase 2 includes installing gravity sewer from the North end of the UGA
east to N Glade Road then running South along N Glade Road to the
future lift station. (Construction has been Substantially completed).
Phase 3 includes a Lift station at the corner of N Glade Road and Burns
Road extended, as well as a set of force mains for the connection of the
proposed system to the existing gravity collection system along Foster
Wells Road and Capital Avenue, and Foster Wells Road and Industrial
Way. (In Construction).
Phase 4 accounts for the remainder of the gravity sewer trunk mains
serving the properties west of the lift station (west of North Glade Road).
(In Construction).
V. DISCUSSION:
On Wednesday, January 10, 2024, the last and northernmost boring was
scheduled to begin below the BNSF railroad along Clark Street (extended).
Non-passable rocks were encountered as the boring began, making the 24-
inch casing deflect and misalign. The steering head was recovered.
It is noteworthy that geotechnical exploration was performed during the design
of the project in adjacent locations to the site of interest and rocks were not
detected. The phase 1 project had successfully executed 5 of the 6 borings
included in its project scope. LiDAR and Ground Penetrating Radar (GPR) are
used for surface and minimal depth scanning and would not be effective in
applications where deep ground condition assessments are desired.
Bore operation was halted upon failure on January 10, 2024. Several
alternatives were evaluated. A few key considerations were:
Estimated success rate of reattempting the 24-inch bore was very low.
Risk of damaging the equipment and losing the steering head was high
and expensive.
Page 4 of 25
The site of the bore has constraints from existing (recently installed)
utilities on the east, or receiving bore pit, along Railroad Avenue.
Existing power lines parallel to the south of the pipeline alignment.
Federal (USBR) and State(DNR) lands are adjacent to the project, so
permitting those new locations would be time-consuming.
These constraints prevented the project team from defining a new
alignment for the bore.
An increased (36-inch) casing would allow for a drill to be deployed into
the casing to fracture any rocks encountered along the alignment of the
bore.
A failed bore attempt further along the alignment would force the
equipment to be abandoned in place, rendering the alignment no longer
feasible, and increasing the cost and timeline of the project significantly.
Increasing the casing diameter from 24 inches to 36 inches was deemed the
preferred alternative, considering the likelihood of success and the lower
potential cost of all other alternatives.
This will constitute a change order to the project.
This item was presented to Council at the January 16, 2024, Regular meeting
as a discussion item.
City Staff recommends approval of Change Order No. 7 for the East Urban
Growth Area (UGA) Expansion Sewer Local Improvement District (LID) No.
152 Phase 1 Project.

East UGA Expansion Sewer LID (LID 152) Change Order Summary List:
1) Change Order 1 – Sales Tax Increase from 8.7% to 8.9% ($3,787.96): This
change order accounts for the increase of Sales tax from 8.7% to 8.9% that
began January 1st, 2023.
2) Change Order 2 – Cost Increase due to delay of Project ($54,461.86): This
project was delayed due to extended right-of-way acquisition negotiations for the
lift station parcel, permanent and temporary easements. This change order
addresses the cost to the contractor and their subcontractors to revise schedules
and storage of materials.
3) Change Order 3 – Casing Upsize for Phase 3 Force Main($28,647.89): This
change order addresses the increased size of the casing needed to be installed
for the Phase 3 contractor to be able to install the designed force main.
4) Change Order 4 – Slide rail receiving pit and work area reduction due to
change of existing conditions ($134,403.12): This change order includes the
cost needed to have and utilize a different form of shoring due to the constraints
of the site conditions differing from design because of the Darigold contractor
installing and shifting Railroad Ave along this projects construction area.
5) Change Order 5 – Additional shoring to prevent schedule delays
($22,337.27): This change order includes the Contractor ordering and utilizing a
second set of shoring to allow the use of multiple bore pits. This gives the
contractor flexibility to continue work and be prepared for the BNSF flagger
instead of incurring standby time.
6) Change Order 6 – Casing Upsize for Clark Road and BNSF crossing
($36,331.72): This change order includes the pricing for the most readily
available 36 inch casing to be ordered because the previous 24 inch bore failed.
This casing is needed to continue work as quickly as possible to reduce the
standby. The bore operation was shutdown on January 10, 2024 when rocks and
deflection of the casing were encountered.
7) Change Order 7 – Casing Upsize for Clark Road and BNSF crossing
($1,087,386.60): This proposed change order includes; the remaining amount of
the 36 inch casing to complete this bore, all contractor and subcontractor costs to
complete this bore, the removal of the 22 feet of the failed 24 inch casing bore,
the rock removal that could be associated with the current rock findings at both
ends of this bore, and the six days of standby time incurred due to the 24 inch
casing failing. Due to changing the casing size, the remaining funds within Bid
Item 5 "Trenchless Crossing and 24" Casing for Clark Rd BNSF Crossing" will be
removed from the contract amount. Decreasing the amount by $364,557.00.

Risk of continuing with 24 inch casing as “very high and very costly”
If the 24 inch bore is attempted again and fails underneath BNSF right-of-
way, cost and schedule delays will be significant.
A revised sewer alignment is problematic within the project schedule.
o DNR property to the north and USBR property to the east
o Power poles and powerlines immediately south
o New easements from Lamb Weston and USBR needed if sewer if shifted south
o Easterly terminus of bore is a fixed point in order to serve Reimann Industrial Center
o Designed sewer slopes are close to minimum slope in order to minimize depth
