This was a complex renovation and retail expansion project on an existing occupied building. I Hittite Steel furnished and installed the structural steel and miscellaneous metals in a timely and professional manner. Because this project was on a tight schedule and to an existing building, additional coordination and flexibility were required. From the start of the shop drawing process, Hittite ably coordinated their steel to fit the existing structure and with the new storefront. This process was done in advance in order to release the storefront glass to meet the project schedule. Hittite exceeded their schedule timeframe and had the structural supports complete and accurate prior to the storefront arriving on site. Hittite also worked closely with our field staff, owne/s representatives, and other subcontractors to maintain access to building entrances at all times. Hittite was more than cooperative working within these constraints and still able to meet the schedule by working off hours work and remobilizing as needed. Your company's attitude towards good quality workmanship and timely performance is what I want in subcontractor and I look forward to continuing our working relationship in the near future.
