RECOMMENDATION
Staff recommends the City Council approve an amendment to the existing professional services agreement with NV5 for construction management and inspection services in an amount not-to-exceed $122,532 for the Construction of Diversion Sewer Pipes to Abandon Mesmer and Overland Sewer Pump Stations, Project No. PZ-946.
BACKGROUND/DISCUSSION
On March 18, 2019, the City Council (1) awarded a construction contract in the amount of $11,732,055 to Ramona Inc, for the construction of Diversion Sewer Pipes to Abandon Mesmer and Overland Sewer Pump Stations, Project No. PZ-946; and 2) approved a professional services agreement in an amount not-to-exceed $419,865 (plus $42,000 contingency amount) to NV5 for construction management and inspection services. The completion of this project will allow the sewer flow from Mesmer Station and Overland Station be diverted to the newly completed Bankfield Station. The Mesmer Station is proposed to be repurposed to a low flow diversion project.
On January 11, 2021, the City Council approved a contract amendment to NV5’s contract in the amount of $235,548 to extend the construction management and fulltime inspection services from November 2020 through May 2021, due to outside agency permitting delays and unexpected night work as required by City of Los Angeles for work within their jurisdiction.
The additional change order as approved by the City Council for NV5 was expended in August 2021. NV5 is requesting an estimated $122,532 to cover August 2021 through November 2021 for additional construction management and inspection services until project completion. In the revised permit from Caltrans, it is required that the abandoned sewer mains under the 405 and 90 freeways be filled in with slurry and this has extended the construction duration
The total projected construction engineering fee to be provided by NV5 is $800,903, which represents 6.7% of the construction cost. This is considered a low percentage in the industry for construction engineering.
