"I want to take this opportunity to thank you and the team of construction professionals you assembled to work so diligently over the past two years to create the GE Sensing manufacturing and office facility in Billerica. It is hard to imagine how you might have done better. Your budgets were tight, yet you stayed within them. Your schedules were aggressive, yet you met every milestone. The quality of your work was superior and everyone within your firm, in the office and in the field, was thoroughly professional. The end-result exceeded our expectations and you and everyone at J. Calnan & Associates should take great pride in what you achieved."
