WHO WE ARE

PROFESSIONAL QUALIFICATIONS

Seal Engineering, Inc.’s professional staff consists of civil and structural engineers.  Professional engineers are registered to practice in the Commonwealth of Virginia, Maryland, the District of Columbia, and West Virginia.  All staff engineers are trained, experienced and licensed to operate laboratory and nondestructive materials testing equipment.

SPECIALIZED EXPERIENCE

We pride ourselves on careful and thorough investigations and reports.  Our recommendations and designs emphasize maintenance and repair whenever possible to maximize the service life of the building envelope.  We recommend replacement only when it is clearly the most practical and economical alternative.  Our engineering services have proven successful in the bidding process, where our sound, clear and practical designs and bid packages have obtained truly competitive bids.  For special assistance beyond our capabilities, we work closely with several architectural and engineering firms, materials consultants and testing laboratories.

QUALITY CONTROL/ ASSURANCE

Our rigorous internal quality control/assurance program ensures coordinated and technically accurate reports, plans, designs, specifications and construction cost estimates.  Work performed by our engineering designers and consultants is carefully reviewed by our Quality Control Principal, David DiQuollo.
