Existing Building Engineering

Engineering for Existing Buildings

Existing buildings are the majority of our work. We specialize in evaluating what's already there, engineering what needs to change, and producing the documentation to get it permitted and built.

Existing Building Assessment

Existing Building Condition Assessments

A condition assessment documents the current state of a building's structural system or MEP systems — identifying deficiencies, pr…

No Drawings? No Problem.

Structural Engineering When Existing Drawings Aren't Available

A large percentage of existing building projects have no drawings on file. Engineers work through this all the time — using field …

Field Verification Engineering

Engineering Field Verification for Existing Buildings

Field verification collects the physical data about an existing building that engineering design depends on — member sizes, connec…

Contractor Field Documentation

Contractor-Assisted Field Verification for Engineering

When contractors provide high-quality field documentation — photographs, measured dimensions, framing member sizes from exposed co…

Structural Crack Evaluation

Structural Engineering Evaluation of Building Cracks

Building cracks range from cosmetic shrinkage cracking to indicators of significant structural movement. A structural engineer eva…

Foundation Problem Engineering

Structural Evaluation of Foundation Issues

Foundation movement — settlement, heave, lateral movement, or deterioration — can manifest as building distress symptoms well abov…

Settlement Engineering

Building Settlement Evaluation and Structural Engineering

Building settlement — the gradual or sudden sinking of foundations into the soil — can cause structural damage, operational proble…

Roof Modification Engineering

Structural Engineering for Roof Modifications

Modifying an existing roof — adding equipment, cutting new penetrations, installing solar, changing roofing systems, or adding a r…

Rooftop Equipment Structural Engineering

Structural Evaluation for Rooftop Equipment

Adding or replacing equipment on an existing roof imposes loads on the structural framing below. Engineering verification confirms…

Wall Opening Structural Engineering

Structural Engineering for Existing Wall Openings

Creating new openings or widening existing openings in load-bearing walls requires structural engineering — confirming the wall's …

Structural Repair Engineering

Engineering Design for Existing Building Repairs

Structural repairs in existing buildings require engineering design — not just contractor judgment. The repair must address the ac…

Existing Building · City Records

Structural Engineering From City Building Department Records

City and county building departments maintain permit records, plan sets, and inspection histories for buildings constructed under …

Existing Building · Contractor Photos

Structural Engineering From Contractor Photos

When contractors open walls, ceilings, or floors to expose existing framing during demolition or rough-in, the information documen…

Existing Building · Site Visit

When a Structural Engineer Needs a Site Visit

A structural engineer site visit may be required when existing conditions are complex, when contractor documentation is insufficie…

Existing Building · Exploratory Openings

Exploratory Openings for Existing Building Engineering

When existing drawings are unavailable and visual observation from accessible areas is insufficient, exploratory openings — contra…

Existing Building · Roof Framing

Existing Roof Framing Engineering Evaluation

Existing roof framing must be evaluated before adding loads, cutting openings, or modifying the framing system. Engineering assess…

Existing Building · Floor Framing

Existing Floor Framing Engineering Evaluation

Before adding heavy equipment, mezzanines, elevated storage, or occupancy changes, existing floor framing must be evaluated for st…

Existing Building · Masonry

Existing Masonry Wall Engineering Evaluation

Masonry walls — concrete masonry units (CMU), brick, and block — behave differently from wood and steel framing and require specif…

Existing Building · Electrical

Existing Electrical Service Engineering Evaluation

Before adding significant electrical loads — new equipment, EV charging, expanded tenant space, or system upgrades — the existing …

Existing Building · HVAC

Existing HVAC System Engineering Evaluation

Understanding the existing HVAC system's capacity, condition, and limitations is essential before planning modifications, addition…

Existing Building · Plumbing

Existing Plumbing System Engineering Evaluation

Modifying a commercial building's use, expanding the occupancy, or changing plumbing fixture counts requires evaluating whether th…

Existing Building · Seismic Retrofit

Seismic Retrofit Structural Engineering

Seismic retrofit improves the earthquake resistance of existing buildings that were designed to earlier, less stringent seismic co…
