OUR WORK

About Our Structural Engineering Services

Our structural engineering services support residential and commercial construction projects, including new buildings and modifications to existing structures. Because Highland provides structural engineering alongside architectural, civil, and MEP services, your structural design is developed as one coordinated set — confirming the structure works with the architecture and site before the plans reach an agency.

STRUCTURAL DESIGN SERVICES

From loads to a permit-ready structure

A typical Highland engagement starts with a building and a goal. We confirm what the structure needs to carry, engineer the foundations and framing, complete the calculations, and carry the stamped drawings through agency review — coordinating structure with architecture, civil, and MEP so it builds the way it's drawn, with one team accountable from start to finish.
WHAT's INCLUDED

Organized the way a building actually comes together — from loads to permit documentation.

Organized the way a site actually comes together — from first studies to record drawings.

Foundations & Framing

Foundation Design

Footings, slabs, and foundation systems sized for the building's loads and soil conditions.

Structural Framing Plans

Floor, wall, and roof framing layouts engineered to carry the structure safely.

Existing Buildings & Additions

Stormwater Management (SWM) Design

Detention, retention, and water-quality facilities designed to local SWM criteria.

Site Demolition Plans

Removal plans for structures, pavement, and utilities ahead of redevelopment.

Utilities & Connections

Water and Sewer Utility Design

Public and private water and sanitary sewer extensions and connections.

Domestic Water and Fire Service Connections

Domestic and fire service lines sized and routed from main to meter.

Storm Drainage Systems

Inlets, pipes, and outfalls engineered to convey runoff safely to discharge.

Utility Connections and Coordination

Wet and dry utility connections coordinated with the serving agencies.

Access, Compliance & Documentation

Roadway and Parking Lot Design

Geometry, pavement sections, and circulation for roads, entrances, and parking.

ADA Accessibility and Site Improvements

Accessible routes, ramps, and parking designed to current accessibility standards.

Construction Details and Specifications

Project-specific details and specs that make the plans buildable in the field.

As-Built and Record Drawing Coordination

Record drawings and as-builts coordinated for bond release and closeout.

Every design is developed to be practical and cost-effective — addressing regulatory requirements, constructability, site constraints, and long-term performance.
