  1. RSMeans: A Comprehensive Guide for Cost Estimating and Project Management

RSMeans (originally Engineering News-Record Cost Data) is a widely recognized and respected source of construction cost data utilized by professionals in the architecture, engineering, construction (AEC), and facilities management industries. This article provides a comprehensive overview of RSMeans, its components, how it’s used, and its significance in cost estimating and project management. It will be geared towards beginners, explaining the core concepts and functionalities without assuming prior knowledge.

What is RSMeans?

At its core, RSMeans is a collection of comprehensive construction cost databases. Unlike a simple price list, RSMeans provides *unit costs* – the cost of a single unit of a particular construction item. This unit cost is broken down into several key components:

  • **Material Costs:** The cost of the raw materials required for the item.
  • **Labor Costs:** The cost of the skilled and unskilled labor needed to install the item. This is often broken down by skill level and geographic location.
  • **Equipment Costs:** The cost of the machinery and tools required for installation.
  • **Overhead & Profit:** A percentage added to cover the contractor's general business expenses and profit margin.

RSMeans isn’t just *one* product. It's a suite of products delivered through various platforms. The most prominent include:

  • **RSMeans Data:** The foundational database, containing detailed cost information.
  • **RSMeans inSite:** A web-based platform providing access to the RSMeans Data, along with cost estimating tools and project management features. This is the most common access point for many professionals.
  • **RSMeans Building Construction Cost Data:** A printed book (and now digital format) that provides a condensed version of the data, historically popular but increasingly replaced by digital solutions.
  • **RSMeans Facilities Maintenance & Repair Cost Data:** Focused on the costs associated with maintaining and repairing existing buildings.
  • **RSMeans Electrical Cost Data, Mechanical Cost Data, and Plumbing Cost Data:** Specialized databases focusing on specific trades.

Why is RSMeans Important?

RSMeans data is crucial for several reasons:

  • **Accurate Cost Estimating:** Provides a reliable basis for developing accurate construction cost estimates. Accurate estimates are fundamental for securing funding, bidding on projects, and managing budgets. Cost Estimation is a critical skill.
  • **Project Feasibility Analysis:** Helps determine whether a project is financially viable. By comparing estimated costs to potential revenue, stakeholders can make informed decisions about proceeding with a project.
  • **Budget Development & Control:** Provides a benchmark for tracking project costs and identifying potential overruns. Budget Management is essential for project success.
  • **Value Engineering:** Allows for the analysis of different construction methods and materials to identify cost-saving opportunities. Value Engineering can significantly impact project profitability.
  • **Contract Negotiation:** Provides a solid foundation for negotiating fair and reasonable contract prices.
  • **Dispute Resolution:** Can be used as evidence in resolving construction disputes related to cost.
  • **Benchmarking:** Allows comparison of costs across different projects and locations.

Understanding the RSMeans Data Structure

The RSMeans data is organized hierarchically. Here’s a simplified overview:

1. **Division:** Based on the Construction Specifications Institute (CSI) MasterFormat, a standardized system for organizing construction information. There are 50 divisions, representing different aspects of the construction process (e.g., Division 03 - Concrete, Division 09 - Finishes). Understanding CSI MasterFormat is vital when working with RSMeans. 2. **Section:** Each division is further broken down into sections, representing specific components or tasks within that division (e.g., 03 30 00 - Cast-in-Place Concrete). 3. **Item:** The most granular level, representing a specific construction item (e.g., 03 30 00 - Cast-in-Place Concrete - Formwork for Walls). 4. **Assembly:** Predefined combinations of items, representing common construction assemblies (e.g., Exterior Concrete Wall). Assemblies can save significant estimating time.

Within each item, you'll find detailed cost information, including:

  • **Unit of Measure:** (e.g., per square foot, per linear foot, per each).
  • **Material Cost:** The cost of the materials required for one unit of the item.
  • **Labor Cost:** The cost of the labor required for one unit of the item, broken down by skill level.
  • **Equipment Cost:** The cost of the equipment used for one unit of the item.
  • **Total Cost:** The sum of material, labor, equipment, overhead and profit.
  • **Location Factors:** Adjustments to the base costs based on geographic location. These factors account for differences in labor rates, material prices, and other regional factors. Location Factors are crucial for accurate estimates.

How to Use RSMeans inSite (A Walkthrough)

RSMeans inSite is the primary platform most users interact with. Here's a basic walkthrough of how to use it:

1. **Login:** Access the platform through a web browser with a valid subscription. 2. **Project Setup:** Create a new project and specify the project location. This is crucial for applying the correct location factors. 3. **Navigation:** Use the CSI MasterFormat hierarchy to navigate to the relevant division, section, and item. The search function is also extremely useful. 4. **Cost Selection:** Select the appropriate cost item based on the project specifications. Pay attention to the unit of measure and the description to ensure it accurately reflects the work being performed. 5. **Cost Adjustment:** RSMeans inSite allows you to adjust the costs based on various factors, such as:
