ZDS provided professional engineering design, bidding, construction administration, and commissioning services for HVAC upgrades at the Tyler Consolidated Middle/High School to meet Indoor Air Quality and today’s energy codes.  The initial step in the project was to provide engineering investigations of existing conditions where ZDS performed 3D Scan-to-BIM for reliable and accurate 3D capture of “built” conditions to use in design, bidding, and construction. The 3D scans were also valuable to communicate remotely between the Owner and Contractors. The demolition and new work to be included in Phase I of the project included two (2) new high efficient chillers piped so they could be used even during winter months, three (3) new high-efficient condensing boilers, variable water volume hydronic pump system, VAV Air-Handling Units, VAV Blower Coil Units, Fan Coil Units, Energy Recovery Ventilators, DDC control upgrades, select new hydronic piping and ductwork for the equipment, exhaust fans, electric work associated with serving the new HVAC system equipment and new electrical panel-boards. The energy-efficient design qualifies this school for the federal EPAct credit and will provide excellent long-term operating savings to the Tyler County School systems over the life of the new systems. The school remained occupied, and the phasing of the Work was critical throughout the construction process. The project was completed ahead of schedule and within the allocated budget.

Phase II work is under construction and intended to complete the HVAC upgrades, renovate the auditorium, additions/renovations to the headhouse (greenhouse), a two-story addition, and provide highly efficient lighting and renovate the auditorium into a showcase for the community.
