Since 1980 Wendes Systems, Inc.has proven to be the leading choice by estimators with per piece Duct Estimating Accuracy. The Wendes estimating data introduced with the Wendes Mechanical Estimating Manual in 1978 continues to be circulated today and is available for download at no cost. The Manual outlines formulas for manually calculating per piece duct […]
Commercial HVAC construction includes highly specialized engineering, materials and highly accurate multilayer labor costing built on specification driven data. There are four major fundamentals that should apply to all HVAC estimating software to ensure accurate results. Commercial HVAC estimates reire dynamic material and multi trade pricing driven by strict construction specifications. Per piece construction labor […]
HVAC Estimating Fundamentals HVAC commercial projects involve highly specialized engineering, large scale material requirements and highly accurate multi-layered labor analysis detailed in specialized reports. Commercial HVAC estimates cannot rely solely on flat rate price lists extensive databasis of materials and equipment must be updated dynamically. Sheet metal and ductwork fabrication are driven by raw weight, […]
HVAC Estimating Software Fundamentals HVAC projects require involved complex engineering, large material volumes, multi layered and very accurate labor cost analysis. Estimates should include detailed takeoff precision, detailed quantity analysis, precise shop and field labor, detailed material lists detailed in multi function reports. Takeoff data should integrate with spreadsheets and other system integrations. Detailed takeoff […]
HVAC systems require all aspects of air distribution, mechanical fluid lines, refrigeration lines and fabricated Ductwork. All of these items are part of the workflow when estimating HVAC systems manually, with spreadsheets or automated systems. Each of the systems require specialized data. Each system in the workflow requires exact fabrication cost, installation cost and material […]
