In the 1980s, company resources went into transforming the Logan Quarry into a state of the art, fully modernized operation. In honor of our founder, it was renamed the A.R. Wilson Quarry in 1989. In 1986, A.R.’s grandson, Bruce W. Woolpert, joined the company and ushered in a new approach to total quality management. A concrete plant in Redwood City and an asphalt facility in South San Francisco were added, and in 1988, Graniterock reinstituted its Construction Division with California Contractors’ License Number 22.

The year 2000 marked a new millennium and one hundred years of business for Graniterock. There was much to celebrate, but the decade brought the entire nation unexpected challenges.

2020 - Today

Graniterock celebrated its 120th birthday in February 2020 with a giant bash with more than 700 team members and their partners at the Fairmont Hotel in San Jose. The roaring 1920s themed gala took place a few weeks before the Covid-19 pandemic halted normal business operations in March. While many businesses were forced to close to stop the spread of the deadly virus, California’s construction industry was deemed an “essential business” and allowed to continue operations with social distancing, face masks and other regulations in place. Graniterock team members worked diligently through the pandemic with the company taking great measures to keep everyone safe. In January 2023, Peter Lemon, who started at Graniterock as an intern from UC Davis in 1998, was named President and CEO as Tom Squeri stepped down. Tom became co-chairman of Graniterock’s Board of Directors, sharing the duties with longtime board member John Orcutt.
