When this structural and civil engineering consulting firm isn’t providing its expertise to architects, contractors, building owners, municipalities and other companies, its employees are enjoying a host of perks from within the office.

Casual dress and flexible hours are offered daily in Wallace Engineering’s energy-efficient environment. Employees also receive additional pay beyond 40-hour workweeks, as well as raises twice a year.

A fitness boot camp and yoga classes are offered on-site, and there’s a bocce ball court on the roof of the building for those seeking a little fun in the sun. Employees also can enjoy the rooftop for picnics, relaxing, socializing or just to recharge and refresh.

All employees are recognized and receive gifts for their 10-, 20- and subsequent five-year anniversaries, and the value of the gifts increases progressively with tenure.

Management exercises an open-book policy in regard to project and financial performance, allowing employees insight into firm success and decision-making, which also provides the opportunity to learn additional project management and business skills.

All principals and associates have participated in and completed a six-month leadership program titled “1-on-1 Management: What Every Great Manager Knows That You Don’t.”

Once a month, all birthdays are celebrated with cake and ice cream.
