ABD Engineering

ABD Engineering is a family owned consulting firm founded in 1990. Its founder has worked in the industry since 1980, and the staff holds more than 100 years of combined experience. Structural, civil, mechanical, electrical, and software engineering are all handled in house, and building work is issued as a single coordinated drawing set.

A-2 / The firm

Family owned since 1990.

ABD Engineering was founded in 1990 by an engineer who had been working in the industry since 1980. The firm opened as a structural and civil practice, and mechanical and electrical followed in 1996, completing the four discipline building practice. Software engineering has since been added as a consulting service.

A second generation of the family joined in 2008. Both generations currently work on projects, and the firm has remained privately held by the family since founding, with no outside ownership.

Project records are retained from 1990 forward, including calculations, drawing sets, and field reports. For buildings ABD has designed previously, that archive is available when the building is renovated, expanded, or sold.

Ownership
Privately held, family owned. No parent company or outside investors.
Generations active
Two, working concurrently.
Combined experience
More than 100 years across the engineering staff.
Licensure
Professional engineers registered in the states served. Current registrations listed on request.
Clients
Architects, general contractors, developers, municipalities, and building owners.

Practice notes
  • 01Discipline coordination is handled internally. Drawing sets are issued as one package rather than assembled from separate consultants.
  • 02Site visits are included in the scope of assessment, renovation, and repair work.
  • 03Construction phase services cover submittal review, RFI response, and field observation reports.
  • 04The engineer sealing the drawings is assigned to the project from proposal through closeout.
  • 05Licensure varies by state. Registrations for a specific jurisdiction are confirmed before proposal.
A-3 / Services

Scope by discipline.

S

Structural engineering

Design and analysis of steel, reinforced concrete, masonry, and wood framing, from a single beam replacement through a complete building frame. A significant share of the structural work is assessment and repair of buildings already in service, including buildings originally designed by others.

  • Foundation and footing design
  • Gravity and lateral framing
  • Seismic and wind analysis
  • Additions and vertical expansion
  • Condition assessment
  • Repair and strengthening design
  • Shoring and temporary works review
  • Peer review
C

Civil and site engineering

Site work from the property line to the foundation, prepared for review by the authority having jurisdiction. Scope typically includes the drainage design and the agency coordination required to move it through approval.

  • Site layout and grading
  • Stormwater management
  • Erosion and sediment control
  • Water, sewer, and utility design
  • Pavement and parking design
  • Drainage studies
  • Entitlement and permit support
  • Agency coordination
M

Mechanical engineering

HVAC and plumbing design sized to the building's occupancy and operating profile. Work includes new systems, phased equipment replacement in occupied buildings, and surveys of existing mechanical systems approaching end of service life.

  • HVAC system design
  • Heating and cooling load calculations
  • Ventilation and indoor air quality
  • Plumbing and piping design
  • Equipment selection and replacement
  • Energy code compliance
  • System condition surveys
  • Commissioning support
E

Electrical engineering

Power, lighting, and life safety design coordinated against the mechanical set. A large portion of this work is service and distribution upgrades in older buildings, where existing conditions govern the design.

  • Power distribution design
  • Service and panel upgrades
  • Interior and site lighting
  • Fire alarm and life safety
  • Emergency and standby power
  • Load studies
  • Low voltage coordination
  • Arc flash and safety review
SW

Software engineering

Custom software for engineering teams, building owners, and manufacturers, from calculation and design automation tools through complete web and data applications. Each project is scoped in writing before development begins and delivered with documentation, the same way an engineering deliverable is issued.

  • Custom application development
  • Engineering calculation tools
  • Design automation and CAD scripting
  • Web and database applications
  • Data collection and reporting
  • System integration
  • Software architecture review
  • Code review and technical audit

BSchematicSystem selection, structural concept, preliminary sizing, and coordination with the design team.Discipline lead
CPermit setCoordinated sealed drawings and calculations for the authority having jurisdiction, plus written response to plan review comments.PE of record
DConstructionSubmittal review, RFI response, field observation reports, and closeout documentation.Project engineer

Single phase engagements are also taken, including peer review, plan review response, and investigation of failures or distress in existing construction.
