1. What Is RSMeans and Why It Matters

RSMeans Data is a leading construction cost database widely used by contractors, architects, engineers, and estimators. It provides unit costs for thousands of construction items, covering materials, labor, and equipment for nearly every trade.

Each entry includes essential cost details such as:

• Unit of measurement (e.g., per square foot, cubic yard, or linear foot)
• Material cost
• Labor cost
• Equipment cost
• Productivity rates and crew data
• Location adjustment factors

Unlike standard estimating spreadsheets or guesswork, RSMeans is built on real industry research and updated annually to reflect market conditions. This makes it a trusted benchmark for feasibility studies, bids, and cost planning across North America.

Step 2: Set Up Your Account

Once you’ve subscribed, log into your RSMeans Data Online account. Configure:

• Default location: This determines the cost adjustment factor for your city or region.
• Measurement unit system: Choose between Imperial or Metric, depending on project requirements.
• User roles and permissions: If multiple team members are estimating, assign roles for collaboration and review.

3. Understanding RSMeans Data Structure

To use RSMeans efficiently, you need to understand how its data is structured. Each cost item typically includes:

• Item Number: The reference code that identifies a specific material or task.
• Description: Detailed explanation of the item (e.g., “Concrete, 3000 psi, reinforced”).
• Unit Cost Breakdown: Divided into material, labor, and equipment.
• Crew and Productivity Data: Lists the labor composition and daily output.
• Location Factor: Adjustment based on regional cost variations.

This level of detail ensures transparency and traceability — two vital elements of professional estimating.

4. Step-by-Step: Creating an Estimate with RSMeans

Step 1: Start a New Estimate

Once inside the RSMeans dashboard:

1. Click “Create New Estimate.”
2. Name your project clearly (e.g., “Residential Addition – Austin, TX”).
3. Select your base location to apply the correct regional cost factor.

This ensures your cost data reflects local wage rates, material availability, and transportation costs.

---

Step 2: Search for Line Items

Use the search bar to find cost items by:

• Keyword (e.g., “asphalt paving,” “roofing shingles”)
• CSI Division (e.g., Division 3 for Concrete, Division 9 for Finishes)
• RSMeans Item Code

Click on an item to view its breakdown. Each entry displays:

• Material cost per unit
• Labor cost per unit
• Equipment cost
• Total unit price

If your project involves repetitive work, you can save frequently used items to a custom list.

---

Step 3: Add Quantities

After selecting items, input your measured quantities. For example:

• Concrete (CY): 150 cubic yards
• Rebar (LB): 12,000 pounds
• Formwork (SFCA): 3,000 square feet

RSMeans automatically multiplies your entered quantities by unit prices to calculate total costs.

---

Step 4: Apply Location Adjustments

Regional variations in labor and material costs are significant in construction.
Use the built-in location adjustment factor in RSMeans to modify your estimate according to the project’s location.

For instance, a project in New York City will have higher labor and equipment costs than one in rural Texas. This ensures your estimates are geographically accurate and realistic.

---

Step 5: Use Assemblies for Faster Estimating

Assemblies are pre-grouped combinations of multiple line items representing a system or component (for example, “Interior Partition Wall – Drywall”).

Instead of manually adding each component (studs, screws, gypsum board, joint compound, etc.), you can add an assembly that automatically includes all related costs.

Assemblies are particularly useful during:

• Conceptual estimating
• Design development phases
• Feasibility studies

You can adjust dimensions, materials, and finishes within the assembly to match your specific project scope.

---

Step 6: Review Crew and Productivity Data

Each RSMeans item includes crew composition — for instance:

• 1 Laborer
• 1 Carpenter
• 1 Equipment Operator

It also provides daily productivity rates, showing how much work the crew can complete in a day. Reviewing these details ensures your labor assumptions are realistic and aligned with your team’s capabilities.

If you know your crew works faster or slower than the RSMeans standard rate, you can adjust productivity to fit your local performance metrics.

---

Step 7: Include Overhead, Profit, and Contingencies

Once you’ve completed your base estimate:

1. Add contractor overhead and profit (O&P) — typically 10% to 20%.
2. Include contingency allowances for design uncertainty or potential price changes.
3. Adjust markup for risk, project complexity, or schedule demands.

These additions convert your raw cost data into a total construction estimate suitable for client presentation or bidding.

5. Using Square-Foot Models for Conceptual Estimating

When detailed drawings are unavailable, RSMeans offers Square-Foot Models — high-level templates that estimate cost based on building type, size, and quality level.

For example:

• A standard office building: $160 to $250 per square foot
• A mid-range hospital: $400 to $700 per square foot

You simply input:

• Building type
• Gross floor area
• Number of stories
• Quality level (Economy, Average, or Premium)
• Location adjustment

The model outputs a detailed cost summary that can later be refined as design details emerge.

---

6. Reporting and Documentation

After finalizing your estimate:

• Generate a summary report for total project cost.
• Export a detailed line-item report for internal review or client transparency.
• Include notes and assumptions to clarify inclusions, exclusions, and scope boundaries.

Proper documentation enhances credibility, helps clients understand your pricing, and reduces disputes later in the project.

7. Common Mistakes to Avoid

Even experienced estimators can make errors when using cost databases. Avoid these pitfalls:

1. Ignoring Location Factors: Always verify regional adjustments.
2. Not Updating Cost Data: RSMeans updates annually; use the latest edition.
3. Overlooking Crew Productivity: Your team’s pace might differ from RSMeans standards.
4. Forgetting Soft Costs: Add design, permits, and administrative expenses where relevant.
5. Skipping Validation: Always cross-check major items with supplier quotes.

9. Advanced Tips for Professionals

• Integrate RSMeans with Takeoff Tools: Import quantities from digital drawings for faster estimates.
• Maintain Historical Cost Records: Track previous projects to benchmark and calibrate future bids.
• Review Annual Updates: Construction costs fluctuate — regularly compare year-to-year data.
• Use Custom Assemblies: Build company-specific templates for repeated work types (e.g., foundation systems, interior partitions).

These habits not only improve speed and accuracy but also make your estimates defensible and repeatable.
