What are Construction Cost Codes?

Construction cost codes are identifiers. They are unique and are assigned to different categories of expenses. These codes help track costs in a systematic way. One such system is the Master Format by the Construction Specifications Institute (CSI). It's widely used by US contractors. The master format includes 50 divisions. Each represents a different phase of construction. Some examples are masonry, electrical, or plumbing.

Please keep in mind, though, that building companies often make their own list of standard construction cost codes if the CSI's list doesn't fit exactly.

The CSI Master Format: A Standard Construction Cost Codes List

The Master Format is an extensive standard for construction cost codes. The list includes:

  • 00: Procurement and Contracting Requirements

General Requirements Subgroup

  • 01: General requirements

Facility Construction Subgroup

  • 02: Existing conditions

  • 03: Concrete

  • 04: Masonry

  • 05: Metals

  • 06: Woods, plastics, and composites

  • 07: Thermal and moisture protection

  • 08: Openings

  • 09: Finishes

  • 10: Specialties

  • 11: Equipment

  • 12: Furnishings

  • 13: Other divisions

These divisions are further broken down into specific categories for more detailed tracking.

Benefits of Using Cost Codes in Construction

Using construction cost codes provides several tangible benefits:

  • Efficient Budget Tracking: These codes allow for real-time tracking of costs. This helps in the closer monitoring of budgets. You can make timely adjustments as needed.

  • Cost Standardization: Cost codes help standardize cost categories across projects. This eases cost comparison and analysis.

  • Real-Time Cost Tracking: Cost codes provide updated financial data. They track costs as they occur.

  • Pinpoint Profitability vs. Weak Points: These codes identify profitable areas in your project. They also point out areas needing improvement.

  • Precise Estimating for Future Projects: Past project data guides future cost estimates. Cost codes make this data more accurate.

What Do You Find in a Cost Coding Structure?

A cost coding structure has unique codes. These represent different types of costs. The codes are grouped in a systematic way. This shows the relationship among different cost categories.

Consider an example. '03' denotes the 'Concrete' division. '30' represents a specific task like 'Casting Concrete'. The next level '01', '02', and '03' denote 'Labor', 'Materials', and 'Equipment'. So, the cost code '03-30-01' stands for the labor cost for casting concrete.

Construction Phases and Types

Cost codes can be allocated according to construction phases. Some examples are design, warranty, tenant improvements, and more. Each phase has different tasks. Unique cost codes can be assigned to each task. Similarly, different construction cost types can have unique codes. Examples of these types are labor, equipment, and materials.

How to Implement Cost Codes in Your Construction Business

Creating and using a construction cost code list can be simple. You just need to remember four key points:

  1. Stick to the Essentials When Making Unique Cost Codes: Assign a single code to a specific subcontractor's work. This will streamline the process.

  2. Consider All Stakeholders Needs: Create your cost codes according to the needs of those using them.

  3. Don’t Stop With Cost-Tracking: Use the data collected from cost codes for making better decisions.

  4. Use Construction Accounting Software: Using software will simplify managing your cost codes.
