COVID ANNOUNCEMENT: (Updated 11/16/2020)

CLSI is open for business and ready to meet your engineering and surveying needs. Amid the Coronavirus (COVID-19) challenges we have been forced to make changes to our standard procedures with some staff working remotely and limiting access to our office. We want to do our best to safeguard our staff and their families while meeting the directives of the Government. We also need to maintain our ability to execute the work and meet your expectations.

Access to our office is restricted to staff only. We request all meetings to be held virtually or on the site. If we agree to an in-office meeting, those entering the office are required to wear face coverings. There is a dropbox in the porch vestibule which is open 24/7 for sending and receiving correspondence.

We will continue to work as efficiently as possible with the understanding that many government agencies have redeployed some of their staff to telework and, as a result, we anticipate delays addressing concerns, scheduling meetings, and obtaining comments/approvals like we did in the spring months.

We are confident that with the measures we have put into place, we can minimize disrupting the business at hand. Please contact your Project Manager should you have any questions or concerns.

CLSI has a diverse staff of qualified professionals experienced in providing a wide variety of planning, engineering, surveying, and environmental consulting services. This allows us to serve the needs of various private and public sector clients in Maryland and Pennsylvania. Our staff included professionally licensed engineers and surveyors with an intimate knowledge of their project assignments from concept through completion.

Located in Central Maryland, CLSI has easy access to all regional project sites as well as to State agencies. We have the staff and technical capability to consistently handle your projects with state-of-the-art technology and innovative approaches that are on the leading edge of the engineering and surveying profession.

Important to our success is that we continue to meet the needs of our clients consistently. We are dedicated to maintaining a high level of performance and satisfaction. It is very fulfilling to us that 90% of our business consists of repeat customers.
