The Importance of Standardized Cost Data to Efficient Construction Delivery

Standardized Cost Data Drive Efficient Project Delivery

The ability to accurately communicate detailed cost data and associated tasks from concept through construction, repair, maintenance, and renovation is critical to efficient life-cycle management for the built environment.

Despite this fundamental fact, construction cost data is rarely communicated in a standardized format that is easily understood by all parties…  architects, engineers, contractors, owners, and building users.

The simple truth is that without detailed line time descriptions of construction task and requirements, communicate in plain English, is it impossible to collaboratively communicate and fully understand budget needs.

standardized construction cost data

Multiple factors impact renovation, repair, maintenance, sustainability, and new construction budgets:

  1. Productivity
  2. Labor
  3. Location
  4. Materials
  5. Project Size
  6. Materials
  7. Time
  8. Site Factors
  9. Construction Delivery Method
  10. ….

Building Cost Models – Uniformat II

Building cost models are based upon major buildings systems as defined by the Uniformat II classification system.

Building and/or system models are experience-based and useful for conceptual cost estimating and/or capital renewal and/or life-cycle capital planning.

Building and/or system models are generally based upon the input of parameter values for each major Uniformat category as expressed in square feet, linear feet, ceiling height, number of floors, building type/use, quality, security, productivity, exterior finish, duty use, % heated/cooled, numb er of corners,  and location.

Typical building types include office, laboratory, education, assembly, stadium, warehouse, police, fire, etc.
