We develop an assessment of existing systems for reuse. By assessing existing equipment, we find through testing and evaluation how the equipment is performing. This analysis includes capacity of fans, controls, heating, cooling, ventilation and pressurization of areas being served. Through testing, inspection and engineering evaluation, we develop comprehensive reports that include recommendations for upgrades or reuse along with all associated probable costs. Many times we provide record drawings from data collected in the field using AutoCAD or Revit.
