Tips on Estimating Variable Air Volume Unit Costs from RSMeans
 | Review all construction documentation before proceeding with the estimate for HVAC. It is not unusual to find items on the plans, but not in the specifications; or they may be in the specifications but not on the drawings. Also check any and all communications; the owner may have requested a change or expressed a concern or a specific need, and not have had it included in your drawings or specifications. |
