BACKGROUND Concession Stand No. 2 was built in partnership with the Pleasanton Girls Softball League and the City of Pleasanton in 1993. The stand is in the southeast corner of Parking Lot No. 4 at Ken Mercer Sports Park, adjacent to Softball Field No. 7. The existing 26 -year-old, 12 -by -30 -foot wooden modular building has reached the end of its service life. There is extensive rot and deterioration to the exterior of the building. The existing 100 -amp electrical service is insufficient to meet current building demands. The surrounding concrete sidewalk has settled, creating several potential tripping hazards, and needs to be replaced to provide positive drainage away from the building and to meet ADA requirements. DISCUSSION The Concession Stand No. 2 at Ken Mercer Sports Park Project, CIP No. 17747, consists of removal of the existing building, foundation and surrounding concrete, relocation of the utilities, upgrades to the PG&E service, and installation of the new foundation, utilities, and a prefabricated building. The existing 360 -square -foot wooden modular building will be replaced with a 350 -square -foot prefabricated masonry building, matching the materials and aesthetics of Concession Stand No. 3, which is located further east in Ken Mercer Sports Park by Softball Field No. 6. Working with Recreation Staff, the interior layout of Concession Stand No. 2 was designed to improve the operating workspace within the stand. The building will have a masonry exterior similar to Concession Stand No. 3, a black composite shingle roof and an overhang over the concession stand windows (see Attachment 2). To limit the impacts of construction to the park and reduce the overall cost of the project, a prefabricated building was selected to replace the existing wood building. The building materials have a 50 -year design life and include a concrete floor and masonry walls with a shingle composite roof. LED vandal -resistant lighting fixtures will be used to reduce energy consumption. Low -flow water fixtures will be used to reduce water consumption. The existing utilities that service the current building will be reused, but the PG&E service conduit will have to be upsized to meet current codes. The existing backflow and check assembly will be upgraded to above ground to meet current codes. The surrounding sidewalks will be replaced to install the new building pad, adjust for the new building grades and fix the existing damaged sidewalk. PG&E is currently designing an upgraded service for the new concession stand that will back feed the existing restroom facility. PG&E has not completed their design but has provided a $5,000 estimate for the cost of engineering and installation. Bids Sealed bids for this project were opened on August 27, 2019. A total of ten bids were received, ranging from $429,738 to $716,000, compared with the engineer's estimate of $400,000 (see Attachment 3). The lowest responsible bid was received from Goodland Landscape Construction, Inc. of Tracy, California, in the amount of $429,738. All other bid documents were found to be in order and past work performed by Goodland Landscape Construction, Inc. was Page 2 of 3
