about us

CityScape Engineering (CSE) was founded in 2009 by Hadi Djohan with over 20 years of experience. In 2015, CSE called Port Washington its new home. From the inception, CSE has attracted highly talented and ambitious team members, and together, we’ve established an institution that not only delivers, but is also sensitive to our clients’ needs.

Solutions Engineered is our business philosophy. From the start, our goal has been to provide our clients with excellent customer service while providing economic solutions to their design challenges. Our experience includes design, inspection, quality control, and project management. Our clients come back for our attentive service and value conscious solutions engineered!
