Explanation
§ The Irwin Creek Wastewater Treatment Plant Project is located on Westmont Drive in West Charlotte.
§ The Plant is currently undergoing extensive renovations known as the Irwin Creek Phase 2 Project. Construction will be completed in the spring of 2019.
§ The plant has three existing secondary clarifiers which were constructed in 2000. Clarifiers are circular concrete tanks with metal working components and are 125 feet in diameter.
§ The repair and replacement of the existing secondary clarifiers was initially planned as a future project; however, the metal and concrete deterioration rate and age of the equipment requires faster action to prevent failure.
Action A
§ On January 11, 2016, City Council awarded the low bid price of $39,732,000 to Ulliman Schutte Construction, LLC.
§ The bid included the addition of a new fourth secondary clarifier adjacent to the three existing clarifiers described above.
§ Based on inspection results, it is recommended that replacing the mechanisms and associated work proceed as a Change Order to Ulliman Schutte’s construction contract.
§ The Change Order will accelerate clarifier rehabilitation.
§ The Change Order price is based on existing bid price and similar recently performed work.
§ The new total value of the contract is $42,823,052.
Action B
§ On January 13, 2014, City Council awarded the engineering firm of Hazen and Sawyer a contract for design and construction administration services in the amount of $4,132,979.
§ On January 29, 2016, Amendment #1 was approved for no additional cost. This amendment restructured unused allowances to provide for additional construction administration services.
§ Amendment #2 provides for:
o Additional construction administration services for the time extension for construction.
o Additional field design services due to changed conditions and constructability issues.
§ The new total value of the contract is $4,482,327.
