In 1993 ENGLEKIRK SYSTEMS DEVELOPMENT, INC. (ESDI) was created so as to allow more focus on the development of unique products or ideas that improve the constructibility, function or performance of building systems. In addition to being a service business to help our clients develop technical justification for unique ideas, create design procedures, and obtain regulatory approval, ESDI also invests in the development of its own products, evaluates through test and analysis the performance of the product, and pursues regulatory approval. Cooperative ventures with recognized product manufacturers are then created for the manufacture and sale of the product.
