Strategic Services

As-Built Floor Plans

We capture what exists with precision and reconcile it to the record—so every design, bid, and decision starts from truth.


  • Multi-pass laser capture + photographic notes

  • Reconciled to original CDs/addenda and prior as-builts

  • Modeled to CAD/BIM/REVIT with disciplined layers

  • Versioned updates with narrative change logs

Detailed architectural as-built floor plan generated from laser field measurements, CAD, and BIM data — providing a verified foundation for design, construction, and asset planning.

Strategic Services

Measurement Reports

We pair targeted field verification with the historical record to resolve what a scan can’t—legacy lease lines, intent, and standards.


  • Evidence review: CDs, prior reports, leases, permits

  • On-site checks at lines that move the math

  • BOMA/IPMS/REBNY applied to the intended use

    • Traced USF/RSF/IPMS, Load Factors, Cleanable Area

Measurement report visualization showing reconciled floor area calculations and verified load factors — combining historical records, lease lines, and field data to reveal hidden square footage value.

Strategic Services

Space Accounting

We turn measurements into a governed system so square footage stays accurate as buildings change.


  • Effective dating, suite lineage, exception handling

  • Allocator logic for clean chargebacks/recoveries

  • Approvals and roles; every change leaves a trace

    • Integrations/exports for leasing, finance, BI

Dynamic space accounting dashboard illustrating how square footage is tracked and allocated across a property portfolio — ensuring accurate occupancy data and optimized asset performance over time.

Strategic Services

Square Footage Optimization

We set usage next to allocation and surface specific, trackable opportunities—not generalities.


  • Map real use vs. assigned areas at suite level

  • Before/after exhibits tied to drawings/standards

  • Operational steps for lease/billing/reporting

  • Monitored through change; documented gains (2–4% RSF where misalignments existed)

Before-and-after floor plan comparison highlighting newly identified usable square footage and improved load factors — demonstrating 2–4% revenue-generating optimization opportunities.

Strategic Services

Orders & Occupant Services

Tenant and suite changes are governed as they happen—no more waiting on stale PDFs.


  • Orders submitted in-platform (from the drawing when needed)

  • Approvals, timestamps, effective dates captured

  • Real-time state for leasing/finance/FM reports

  • Less email churn; faster, cleaner period-end

Real-time tenant reconciliation dashboard showing suite changes, move-ins, and allocations — replacing static PDFs with a continuously updated, auditable record.

Strategic Services

Data Centralization

TruSpace™ centralizes drawings, stacking plans, tenant orders, and analytics—so everyone sees the same, current truth.


  • Drawing Vault™: ingestion, indexing, permissions, versioning

  • StackTower™: dynamic stacking from verified data with lineage

  • Orders: request→review→approve workflows + audit trail

  • Smart Data: verified KPIs with click-through to the plan

Centralized data platform showing integrated drawing repository, dynamic stacking plans, and analytics — connecting measurement data, tenant updates, and performance insights in one unified system.

Strategic Services

Smart Data

Smart Data replaces estimates with verified metrics—one dashboard that rolls up the portfolio and drills to suites.


  • KPIs anchored to verified RSF/USF and standards

  • Apples-to-apples side-by-sides across assets

  • Drill-through: portfolio → building → floor → suite

  • Forecasts with provenance and visible variance

Smart Data analytics interface displaying portfolio-wide metrics and KPIs linked directly to verified measurements — enabling accurate forecasting and confident decision-making.

Strategic Services

Certification & Standards Application

We validate areas and make standards choices explicit, producing a package built for lenders, buyers, tenants, and counsel.

  • Independent review + targeted re-measurement

  • Written rationale for standard selection/edge cases

  • Certification letter, variance schedule, exhibits

  • Clear ties back to drawings and calculations

Certified measurement documentation and variance report aligned with BOMA and IPMS standards — providing defensible data for transactions, audits, and lease negotiations.

At Stevenson Systems, building measurement isn’t a drawing exercise; it’s a revenue function. We deliver standards-aligned as-builts and deep Space Accounting that stand up to audit and negotiation—so every inch is billed correctly and every lease model is clean. Across 12,500+ buildings, our single methodology uncovers additional RSF, reduces disputes, and strengthens valuations. If precision is the goal, defensibility is the outcome—and revenue follows.

The Art and Science of Measured Space

Behind every successful portfolio is more than data — it’s the discipline of precision. Stevenson brings together decades of expertise, unrivaled accuracy, and next-generation portfolio-wide analytics to reveal opportunity where others only see floor plans.

This is how space becomes strategy.

Precision That Defines an Industry

Four decades of rewriting how the world measures, values, and manages real estate.

Stevenson Systems has been a co-author of all the Building Owners and Managers Association (BOMA) measurement standards over the past 30 years. Our rigorous approach is further reflected in our strategic application of these measurement standards. And as the industry grows internationally, Stevenson Systems continues to lead the way, playing a pivotal role in the creation of the International Property Measurement Standards (IPMS). After thirty years of creating, interpreting, and applying the standards, we certainly know how to make them work for you.

New Development

During the critical conceptual and detailed design phases, Stevenson Systems develops strategies that improve load and loss factor efficiency, usable-to-rentable ratios, and floor plate efficiencies based on the multiple measurement standards required for leasing, FAR, tax and meeting municipal requirements. Using our proprietary information, studies are carried out on comparable properties and market competitiveness.

Asset Lifecycle

Redevelopment & Reposition

Whether you’re on the purchase or sale side of an acquisition, accurate building measurements and current lease data are essential for establishing rentable benchmarks, and maximizing dollar-yield. Stevenson Systems works with your timeframe.

Asset Lifecycle

Acquisition

For existing structures, Stevenson Systems begins by developing a unique strategy based on the availability of architectural drawings, and/or CAD files. Field verified as-built floor plans are created by our expert team using advanced laser technology. The appropriate measurement standard is then applied to calculate the building’s square footage, and a Space Analysis™ study is provided, outlining our findings and offering guidance on how to maximize your profitability.

Asset Management

We work with building owners, managers, and leasing representatives to accurately capture all suite and respective occupant leasing information. Detailed drawings are provided with individual suite calculations based on improvements, which include their respective square footages. This information is maintained by our TruSpace™ Orders group, which prevents square footage loss as occupancy and spaces change.

Operations & Maintenance

Stevenson Systems’ Occupant Services improve your leasing team’s capabilities by providing preliminary suite calculations, based upon the proposed new suite demising walls, within one business day. Occupant improvements and close-out CAD files are stored in our Drawing Vault, with instant access to your drawings and CAD files wherever you are.
