M&S Mechanical has expanded its Corporate Interiors Construction division, adding Salvatore Cammalleri as vice president, estimating and Kristin Haufmann as assistant estimator. The two boast more than 35 years of combined experience and longstanding relationships with architects, engineers and general contractors.
Cammalleri recently served as director of estimating for Donnelly Mechanical, helping to double its construction revenue and securing more than $300 million in project awards. Prior to Donnelly, he worked as estimator/project manager and purchaser for BP Mechanical Corp.
Haufmann most recently worked with Donnelly Mechanical and BP Mechanical, supporting their estimating departments. She has a proven ability to pre-analyze projects and ITBs, organize trades, schedule operations and close out jobs. She will be a key team member in coordinating timely responses to general contractors and working with project managers to stay proactive with project scope and data.
“Salvatore and Kristin have a proven track record of success in the estimating field and have been essential to their teams’ success,” said Sal Amato, president and CEO, M&S Mechanical. “We look forward to their helping M&S continue to grow its tri-state presence.”
M&S Mechanical is a one-stop-shop for commercial HVAC, plumbing and fire suppression services.
