Municipal Regional Permit Order No. R202015-0049 (MRP) requires the City to implement a trash capture program to reduce the trash load to the San Francisco Bay. The cooperative agreement relocated Caltrans' required trash capture device to the Koll Center Parkway public storm drain outfall at Bernal Corporate Park. The device will capture trash from most of the Bernal Corporate Park campus, portions of Bernal Avenue and portions of Caltrans' 1-680 and Bernal Interchange (an aggerate total of 92 acres). The BioClean trash capture device will be installed in-line with the 60-inch diameter storm drain line within the parking lot of 6900 Koll Center Parkway (see Attachment 2 for the Location Exhibit). The trash capture device is a prefabricated concrete structure, with baffles and screens, approximately 10 feet wide, 18 feet long, and 17 feet tall. It consists of stainless-steel-screened areas that collects floating trash, a sediment box area to collect sand and other debris that sink, and an oil and grease trap. The device will need to be cleaned two to three times a year, depending on the loading of the system. The device will be located within an existing storm drain easement. A License and Connecter Pipe Screen Maintenance Agreement was made with the owner of the property, Common Area Tract 9755, to provide additional access for construction and maintenance of the devices. A large excavation, approximately 15 feet wide, 25 feet long, and 18 feet deep, is required to set the prefabricated structure. The area will be dewatered and will be monitored to ensure there is no movement at the existing buildings. The project also includes restoration of the parking lot and landscaping. Additionally, the work includes any required by-pass pumping so the storm drain system will not be impacted by the project. When complete, the only visible parts of the trash capture device will be on-grade access manholes. Bids Sealed bids for this project were opened on February 9, 2021. A total of ten bids were received however, upon review, one bid from Kingdom Pipelines was found to be non- responsive as it did not include all bid documents. Bids ranged from a low bid of $494,600 to a high of$871,113. The lowest bid was submitted by Marshall Brothers Enterprises, Inc. of Livermore, California, in the amount of$494,600 (see Attachment 3 for the Bid Summary). This is approximately 37.3 percent higher than the Engineer's Estimate of$360,000 prepared by CGS. Staff requested that CSG review their estimate and the bids. CSG identified that the estimate they provided inadvertently dropped the proposed contingency and should have been $396,000. CSG also spoke with BioClean and confirmed that their costs have increased due to material cost increases they have been experiencing due the COVID-19 pandemic. In addition, CSG believes that worker safety requirements associated with the pandemic are also increasing costs, and maybe another reason that their estimate is low. CSG also reviewed the project's scope of work to determine if any items could be value-engineered to reduce project costs, but none were identified. The lowest four of the nine bid received are within approximately 20 percent of the low bid, and a further review indicated that the Engineer's Estimate was low, so the low bid of $494,600 from Marshall Brothers Enterprises, Inc. is considered to be competitive and responsive. All other bid documents were found to be in order and past work Page 3 of 4
