At Outsource Drafting, we offer specialized Revit Estimation Services that transform your BIM models into powerful tools for quantity takeoffs, cost planning, and budgeting. Designed for architects, engineers, contractors, and estimators, our model-based workflows ensure that every estimate is accurate, consistent, and aligned with real-world construction requirements—including construction scheduling with estimation for better project planning and resource management. Using your Revit models, project specifications, and LOD standards, we extract detailed material quantities and generate cost data directly from the model. Our estimation process supports both LOD 300 and LOD 400 models, providing clear, coordinated outputs for early-stage budgeting, procurement planning, and detailed bid preparation. We deliver precise Revit quantity takeoffs for concrete, steel, walls, finishes, MEP systems, and more—structured by cost codes, construction phases, and zone-based breakdowns. Our model-driven approach minimizes manual errors and ensures your estimates stay in sync with design changes.
Why Choose Our Revit Estimation Services
Our Revit estimation services connect BIM models with precise cost data and quantity take-offs. By delivering accurate estimates, we help contractors, architects, and project owners improve budgeting, reduce waste, and make informed decisions.
Accurate Estimates with Revit Quantity Takeoff
Our outputs are fully compatible with Autodesk Construction Cloud (ACC), BIM 360, and leading cost estimation tools. Each estimate is dynamically linked to the model, ensuring real-time updates with every design change. This automated approach minimizes manual effort, improves accuracy, and supports smarter, data-driven decision-making at every stage of the project lifecycle.
Automated Quantity Takeoffs
We automate the extraction of quantities for materials, systems, and components directly from your Revit model. From walls and finishes to HVAC and electrical systems, our parametric takeoffs update dynamically with design revisions—ensuring accuracy and reducing manual rework.
Cost Estimation Integration
We integrate unit rates and cost data into the Revit model to generate real-time, design-aligned cost estimates. Whether you're using internal databases or vendor-specific pricing, our workflows ensure estimates reflect actual design decisions and current market conditions.
Customizable Reporting
Our reports are tailored to your project's specific requirements—whether you need detailed material breakdowns, high-level budget snapshots, or quantity schedules for tenders. We format outputs based on CSI, Uniformat, or custom standards to align with your cost control and documentation processes.
Value Engineering and Optimization
With access to real-time quantity and cost data, we assist your team in identifying cost-saving alternatives, optimizing material selections, and implementing value engineering strategies—without compromising design quality or performance.
Clash Detection and Cost Implications
We incorporate Revit’s clash detection insights into the estimation workflow to identify and assess the cost impact of design conflicts. This proactive approach enables early resolution, minimizes delays, and keeps your project on budget and schedule.
Regular Updates and Revisions
As project designs evolve, we update quantity takeoffs and cost estimates to reflect the latest changes. Our continuous tracking ensures your budgets remain aligned with model progress and scope changes—avoiding late-stage surprises.

How We Work: Our Process for Delivering Accurate, Model-Based Quantity Takeoffs Using Revit
Our Revit Quantity Takeoff Services are tailored for architects, engineers, contractors, and estimators seeking detailed, BIM-integrated quantity data to support cost estimation, budgeting, and procurement planning. Whether for early design budgeting or detailed bid preparation, we extract precise quantities directly from your detailed Revit models for takeoff—ensuring consistency and alignment with real-world construction needs.
Using your Revit files, templates, and project-specific parameters, we generate accurate quantity takeoffs for architectural, structural, and MEP elements. These include materials such as concrete, steel, masonry, finishes, piping, ductwork, and equipment. We structure all takeoffs by zones, floors, phases, or cost codes—based on your project requirements.
Our takeoff workflows are fully parametric and dynamically linked to the BIM model. As design revisions occur, quantities are automatically updated, eliminating manual rework and improving accuracy. We also apply quality control checks at every stage to ensure compliance with project standards, LOD specifications, and estimation formats like CSI or Uniformat.
The result is a clean, reliable quantity takeoff report that supports 5D BIM integration, streamlines procurement and cost analysis, and enhances informed decision-making throughout the project lifecycle.
