Learn Why 4BT’s Data Structure Excels.

Construction cost data must be valid, reliable, and verifiable to objectively and realistically represent current local market conditions.
- Exclusive source of current, LOCAL MARKET commercial construction cost data
- Measurably improve Cost Visibility and Cost Management Capabilities
- Evaluate and validate contractor bids / proposals with verifiable cost data for materials, labor, and equipment
- Eliminate Guesswork: Remove reliance on error prone “market average cost data, location and economic adjustment factors.
- Support LEAN and Value Management Principles: Enable waste reduction, value generation, and continuous improvement by providing verifiable and actionable data.
- Adapt to Market Realities: Ensure projects are not derailed by unexpected cost changes.
Care should be given as to what form of cost data is being used.
Objective, verifiable, and locally researched detailed line-item construction tasks, replete with labor, material, equipment and productivity information, provide the highest level of cost visibility and cost management capability. 4BT exclusively offers this information for any location, with all line-items organized using expanded CSI MasterFormat, enabling clear communication, collaboration, and alignment with all technical domains and participants throughout the planning, procurement, and project delivery lifecycle.
Other, less stringent forms of cost estimating include the following:
- national average line-item cost data (with or without adjustment or localization factors),
- system level cost data,
- assembly level cost data,
- building level,
- and/or other forms of parametric cost data,
- historical cost data and economic factoring,
- contractor, subcontractor quotes.
[NOTE: UNIFORMAT is best used to express functional elements (assemblies) of a repair, renovation, maintnenance, or new build project). It provides a consistent approach that describes associated components across different projects in cost and function. UNIFORMAT primarily use is in early stages of a project where a specific work scope (scope of work/SOW) has not been fully defined and critical characteristics of the projects not yet been determined, or to denote “Assemblies” that are create from MasterFormat unit price book line items. MasterFormat, accounts for specific details of practical knowledge and terminology inclusive of means nd methods, and is primarilpy used at stages of a project where enough particulars and specific work scopes have been established, such as when a project is ready for procurement, or for the development of a reliable cost.]
