About this file

Written by GovTribe AI ·

This is a technical attachment document for a California Micro LBE set-aside solicitation (CON26-0055) issued by the City and County of San Francisco for Golden Gate Park (GGP) Tennis Court Maintenance services. The document contains detailed bump measurement data and repair history for all 18 tennis courts at the Goldman Tennis Center, tracking surface defects from December 2021 through April 2026. The solicitation requires maintenance services for these courts, with a pre-bid meeting scheduled for Thursday, May 28, 2026 at 9:00 a.m. at the tennis center located at approximately 50 Bowling Green Drive in Golden Gate Park. Written questions must be submitted no later than Thursday, June 4, 2026 by 5:00 p.m., and bids are due no later than Thursday, June 11, 2026 by 2:30 p.m. The attachment demonstrates that Lifetime Activities staff has been monitoring court conditions using a custom "bump thumper" measurement device since December 2024, recording bump heights and locations using a grid system to track surface hazards.

The cost estimate for this maintenance contract is $429,000, and a Class A License is required. Courts 9, 10, 11, 12, and 13 are designated for full resurfacing in May 2025, while Courts 1 through 8 and 14-D require bump repairs in May 2025, with Courts 4 and 7 also scheduled for repairs in April 2024. The historical data shows escalating bump conditions across most courts, with varying repair dates documented from May 2021 through May 2023. Addendum #1 was posted on June 3, 2026, though this does not change the bid due date. Questions and bid submissions should be directed to gabriel.meil@sfgov.org and bridget.webster@sfgov.org.

Prior to a measurement device being created for the specific need of measuring court bumps, Lifetime Activities Staff identified the quantity of bumps per court. Since December of 2024, Lifetime Activities has used a custom-made “bump thumper” to measure the height of each bump. In addition, the staff also notates the approximate location of each bump, divot or crack on the court with the use of grid system.

While not a perfectly scientific system, this allows the team to track the location and potential hazard that each blemish may create.
