AGENDA ITEM: Approve Change Order No. 2 for the Old Village Phase 5 and 6 Street,
Drainage and Utility Improvements
SUBMITTED BY: Chad Isakson, Project Engineer REVIEWED BY: Kristina Handt, City Administrator Marty Powers, Public Works Director Jack Griffin, City Engineer
ISSUE BEFORE COUNCIL: Should the City Council approve Change Order No. 2 for the Old Village Phase 5 and 6 Street, Drainage and Utility Improvements?
BACKGROUND: A-1 Excavating was awarded a construction contract on March 16, 2021 to complete the Old Village Phase 5 and 6 Street Drainage, and Utility Improvements. A preconstruction meeting was
held to kick off the construction of the project on April 14, 2021 with the first few months of work to be focused on the deep sewer tunneling along 32nd Street North. The tunneling work was scheduled to be completed from 622 feet east of Lambert Avenue to 250 feet west of Lambert Avenue. Due to obstructions (cobbles / boulders) found the contractor stopped drilling operations on June 3rd. Options to proceed with the project were presented to the City Council at the July 6, 2021 council meeting at which time staff received direction to proceed with finalizing a design for the construction of a city owned lift station to be installed on 32nd Street. Work remains in progress with a milestone 1 completion date of October 15, 2021, milestone 2 completion date of October 14, 2022, substantial completion date of June 30, 2023 and final completion date of July 28, 2023. Milestone 1 is recommended to be amended to reduce the project construction progress that is
required to be completed during the 2021 season to account for the redesign project delay. The milestone 1 completion requirements will now only include the construction of the improvements along 32nd Street between Lake Elmo Avenue and Lampert Avenue.
PROPOSAL DETAILS/ANALYSIS: A change order has been prepared and has been signed by A-1 Excavating, Inc. to address the project redesign, including the installation of a lift station on the city owned
property on 32nd Street with the removal from the scope of work of the deep sewer tunneling that was included in the original design documents. As presented at the July 6 council meeting, the sewer redesign allows for much of the sanitary sewer gravity pipe to be raised up in elevation, eliminating the deep gravity sewer from the project, along with its risks and costs. In addition, the sanitary sewer services for all properties remains unchanged from the original design documents (gravity service vs. grinder station service) and the 15-inch trunk sewer stub that will be located at Klondike and 33rd Street for future extension to the north of the UPRR will remain at a 910 invert elevation.
The engineering team and contractor have been working diligently and collaboratively since the July 6 council meeting to finalize the design details for the new lift station and other design elements. The revised plans and specifications, dated July 30, 2021 have been prepared as an amendment to the contract and will become effective upon council approval of this change order.
At the July 6 council meeting, engineering presented an estimated project cost increase of $410,000 based
on preliminary discussion and estimates with the project team. Change Order No. 2 now details the construction contract cost changes for the redesign based on the final documentation, and this report provides an updated total project cost estimate, along with an itemization of the cost changes that have
occurred since that presentation. With Change Order No. 2, the total project budget will result in an increase of $358,850 (instead of the
$410,000 previously presented). The changes are itemized below:
• Construction / material final design changes resulted in an increase of $34,250 to construct the lift
station. These changes are due to: o Increased pump size from the originally quoted pumps as a result of final design calculations. o Increased height of SCADA communication antenna based on the location of the lift station.
o Revised model of check and air release valves from the materials originally quoted. o Added check valve from the original draft design.
• A site investigation was conducted by the dewatering contractor which resulted in feedback that point well dewatering would likely not be required for construction of the structures. This results in a savings of $75,000 in the final change order. If field conditions later identify the need for this
service, there remains the potential that dewatering would need to be added into the scope of work.
• Engineering redesign fees came in under the estimated budget by $10,400 due to the existing city
standards for lift stations. Included in the $358,859 total project cost increase is an estimated $90,000 budget that the city will need
to pay the power company to extend 3-phase power to the lift station site. Xcel Energy’s design for extension of power to the site is in progress. Until Xcel Energy completes the design, the $90,000 estimate will be subject to change.
FISCAL IMPACT: This change order will increase the construction contract with A-1 Excavating in the amount of $203,950.00 bringing the revised construction contract to $6,697,662.39. This change order will also result in an estimated total project cost increase in the amount of $358,850.00. RECOMMENDATION: Staff is recommending that the City Council approve Change Order No. 2 for the Old Village Phase 5 and 6 Street, Drainage and Utility Improvements. The recommended motion for the action is as follows:
“Move to approve Change Order No. 2 for the Old Village Phase 5 and 6 Street, Drainage, and Utility Improvements, thereby increasing the contract amount by $203,950.00, increasing the total project budget by $358,850.00, and updating Milestone 1 to include 32nd Street from Lake Elmo Avenue to
Lampert Avenue to be constructed in 2021”.

Prepared concrete surfaces must be filled if the surface is too rough. Fairing the surface to fill bugholes and voids to near smooth is mandatory prior to coating application. Some surface texture after filling may be approved and recommended for adhesion of subsequent coats. (OAP) stands for Optically Activated Pigment which may be used for supplementary visual holiday detection. OAP is not a replacement for NACE standard SPO-188-2006. Galvanized metal is not recommended for wastewater immersion due to adverse chemical reaction(s).
