COVID 19 Update (September 2020):

The health of our Employees, Clients, and Colleagues is very important to us.  After the initial March lockdown, where 100% of our employees were working remotely, we now have only personnel working on essential projects in the office.  Those employees coming into the office have followed NYS protocols–wearing masks, keeping 6’ distance, not gathering in groups, hand washing/sanitizing, and submitting health check/contact tracing forms for each day they are in.

The remaining staff continues to seamlessly work from home.  Remote working has been very successful, and as long as it remains workable for our Employees and Clients, we will continue to do so until further notice.

We are proud of our staff for their commitment to providing the best services to our Clients in the middle of a pandemic.  Yet we look forward to the time when we can all be back together.

If you have any questions or are in need of engineering/architecture services, we are here. Call or email us.

Stay Safe. Wear a Mask. Social Distance. Wash your Hands.
