TO: HONORABLE MAYOR AND MEMBERS OF CITY COUNCIL
FROM: DIRECTOR OF PUBLIC WORKS
DATE: SEPTEMBER 16, 2003
SUBJECT: AWARD OF CONTRACT FOR STORM DRAIN SYSTEM VIDEO INSPECTION
Staff Coordinator: Glen W.C. Kau, Sr. Engineer
At it’s regularly scheduled meeting of August 19, 2003 the Council awarded a Professional Services Agreement to AKM Consulting Engineers to perform an update to the 1998 Storm Drain System Master Plan Study. The update will evaluate areas not previously considered, update costs, update hydrology, update base maps to reflect work completed, and convert data into a GIS format. An engineering firm will provide these services and base their evaluation principally on a modeled view of the system to determine if portions of the system are undersized.
To fully understand the City’s storm drain system, an assessment of the field conditions of pipes must also be made. To determine field conditions the services of a firm capable of performing video inspections is required. This report recommends the award of a contract for those services. It is anticipated that approximately 20% of the City’s storm drain system will be inspected by this contract.
The results of this contract together with the results of the Sewer System Master Plan awarded on August 5, 2003, and the Storm Drain Master Plan awarded on August 19, 2003 will provide a comprehensive evaluation of the City’s sewer and storm drain systems.
In similar fashion as the Sewer System Master Plan Study, in order to fully understand the needs of the Storm Drain System, information has to be collected from both the modeled view, and the in-field view as well. The model (calculated) data will provide (predict) what the performance capabilities of the storm drain are supposed to be.
The in-field data (video inspection) will determine what the actual physical conditions of the storm drain pipe are. The hydraulic model can only identify as to where and what branches of pipe (locations) within the storm drain system as being hydraulically deficient based on parameters such as age, material, flow conditions, etc. To validate the hydrology model’s results, video inspection services are required to capture in-field pipe condition information. Video inspection can also be used to determine how the pipe actually performs in the field under flow conditions, as well as indicate what possible methods/options to employ are for rehabilitation. With the Storm Drain Master Plan Update project is just getting underway, the actual locations to be video inspected have yet to be determined. The 1998 Storm Drain System Master Plan already indicated areas considered to be hydraulically deficient. This information will be used as starting information when determining the actual areas to be video inspected.
To acquire video inspection services, staff requested proposals from companies that are familiar with the peninsula and are geographically desirable (mobilization) to receive reasonable costs. With approximately 24,420 linear feet of storm drain pipe in the system, approximately a quarter will be selected for video inspection to collaborate with the model’s results. Video inspection services will be let out in 2,000’ increments to correspond with the findings of the Storm Drain Update Study
Three proposals for On-Call video inspection services were solicited for and received. The most responsive proposal was submitted by National Plant Services (NPS). With a total linear footage of 8,000’, to be let out in 2,000’ increments, their proposal was deemed most responsive. NPS has performed on-call video inspection services for the City on numerous occasions, and has provided excellent service and work product. All video materials will be delivered on Video-CD (VCD), along with the associated video inspection logs. With amount of pipe clearing unknown until actually undertaken, staff recommends that a contract for the not-to-exceed amount of $25,000 be awarded. This amount (which includes both video inspection and pipe clearing) is estimated based on previous pipe clearing efforts experienced from the Mustang Road Storm Drain repair project. Once the storm drain pipe locations have been determined from the Storm Drain System update, the first pipe segments to be videoed will be executed.
Adopting the staff recommendation will award a contract to National Plant Services, Inc. for video inspection services of the Storm Drain System. This video inspection information will be used in conjunction with the Storm Drain System Master Plan Study Update, the existing storm drain system database and maps, and help staff understand the City’s storm drain deficiencies.
Adequate funds are budgeted in the FY 2003-04 Infrastructure Improvement Program for the recommended actions.
When the FY 2003 – 04 Budget was adopted funding for this project, together with funding for the Sewer System Master Plan ($282,440) awarded on August 5, 2003 and the Storm Drain Master Plan Update ($42,164) awarded on August 19, 2003 were inadvertently programmed under maintenance programs rather than the Infrastructure Improvements Program. The attached resolution, which does not revise appropriations, shifts funds to their proper program.
