Dynamic Construction Cost Data
“Dynamic construction cost data” is locally researched, granular, and updated quarterly to reflect current market conditions, unlike static national averages, historical costs, location factoring, etc..
It is used for detailed estimating and cost management in renovation, repair, and new construction projects (example) 4BT OpenCOST(tm) and Benchmark Constructin Estimator(tm) products.
-Dynamic: The cost information is not static; it’s continuously updated to stay current with market changes.
-Cost Data: A comprehensive database of granular line item construction costs, which includes labor, materials, and equipment.
-Granular: The data is broken down into very specific, detailed line items (over 90,000) that represent individual construction tasks, rather than broad categories.
-Locally Researched: Instead of applying a generic factor to a national average, relying upon contractor bids, or using historical costs, 4BT surveys actual local markets to gather data, which results in more accurate pricing for specific projects.
-Updated Quarterly: The data is refreshed every three months to ensure it reflects the most current market conditions.
Key features and benefits
Improved accuracy: Locally researched data provides a more accurate cost basis than national averages adjusted by a location factor.
Detailed breakdown: The granular, line-item data allows for more detailed and verifiable cost estimating.
Standardization: The data is organized using expanded CSI MasterFormat, which provides a consistent and uniform language for all project stakeholders.
Supports various projects: It can be used for new construction, renovation, repair, and maintenance projects.
Supports specific contracting models: It is widely used for Job Order Contracting (JOC) and other LEAN construction methodologies.

4BT OpenCOST(tm) is recognized as the only source of locally researched, current, and granular construction cost data that is organized using expanded MasterFormat and updated quarterly—without relying on economic or location factoring. This approach delivers unique transparency and accuracy compared to nationally averaged cost databases.
4BT OpenCOST Key Features
-Locally Researched Costs: 4BT actively surveys local markets for labor, materials, and equipment, rather than applying broad location multipliers to national averages.
-Granular Data Structure: The database contains over 90,000 detailed unit price line items, covering most typical tasks in renovation, repair, maintenance, and new construction.
-Expanded MasterFormat Organization: Line items are structured using CSI MasterFormat divisions and sections for clarity and consistency across all estimates.
-Quarterly Updates: Data is refreshed quarterly (with major annual revisions), ensuring cost information reflects recent market shifts and localized fluctuations.
-No Economic or Location Factoring: Costs are not estimated using multipliers or indexes but are instead directly based on in-region market research, avoiding errors often introduced by averaging and adjustments.
-Objective and Independent: The methodology is transparent, and the data is defensible for audits, benchmarking, and procurement under best-value frameworks.
Industry Context
Competing databases (RSMeans/Gordian, BNI, etc.) often rely on national averages adjusted by location factors, which can result in significant estimating errors for local projects and lack the transparency required for best-value construction delivery.
4BT’s data is preferred for projects demanding audit-ready, line-item cost control and transparency, especially under Job Order Contracting (JOC), LEAN, and Integrated Project Delivery (IPD), and validation of contractor and subcontractor quotes.
For owners, contractors, and estimators who require precise, verifiable, and locally specific construction cost data organized using industry standards, 4BT OpenCOST stands alone in its methodology and update practices.
Leveraging current, actionable data is key for sustainable Facility Management including repair, renovation, maintenance, and new construction
For example, utilizing dynamic PM cost and task data, organizations can optimize building operations, maintenance, and planning.
This approach not only lowers costs but also extends the lifespan of buildings and equipment while supporting the organizational mission.
