Service scope

Resolve the structure around units, parking, and shared spaces

The work is matched to the building configuration, site information, jurisdiction, and current design phase.

  • Compare structural systems for spans, unit repetition, and construction approach
  • Analyze gravity and seismic loads, then design foundations, framing, and connections
  • Resolve corridors, stairs, shafts, and major openings across the plans
  • Coordinate structural requirements with architectural, civil, geotechnical, and building-system teams
Architect and Professional Engineer coordinating a structural grid on multi-family building plans
Early grid, core, and opening decisions give the full design team a consistent structural basis.
Coordinated multi-family structural plans, details, and calculations arranged on a desk
Plans, details, and supporting calculations are developed as one coordinated package.

Project deliverables

Give the architect, city, and contractor one structural package

Exact deliverables are confirmed after NBE reviews the project requirements and available information.

  • Structural plans, schedules, and connection details
  • Supporting calculations with documented assumptions
  • Professional Engineer-stamped permit documents when included
  • Plan-check responses, revisions, or field clarifications when included

A clear path forward

Go from concept plans to documents the team can use

  1. 01Step
    Step 01

    Share the project

    Send the site, concept plans, unit program, jurisdiction, schedule, and the decision you need to make.

  2. 02Step
    Step 02

    Set the structural approach

    NBE confirms the work required, evaluates the structural system, and resolves major conflicts with the project team.

  3. 03Step
    Step 03

    Advance the project

    Receive the agreed plans and calculations for plan check and construction, with continued support when included.

Why NBE

Make the expensive structural decisions while the plans can still change

Early decisions about grids, spans, foundations, and openings help preserve repeatable layouts and a consistent permit set.

Preserve repeatable unit layouts
Catch shaft and stair conflicts before permit
Keep construction answers tied to the approved design

Clear Communication From First Question to Next Step

“Their quality of work and customer service is excellent.”

Clear communication helps owners and project teams move from structural questions to usable next steps.

Frequently Asked Questions

What types of multi-family projects does NBE support?+

NBE supports structural engineering for apartments, condominiums, townhomes, and other multi-unit housing. The appropriate scope depends on the building configuration and project phase.

Can you evaluate structural systems before design is complete?+

Yes. Early structural input can compare feasible systems and identify coordination issues before the team advances the documents.

Do multi-family plans require coordination with other consultants?+

Typically, yes. Structural work commonly coordinates with architectural layouts, foundations and civil information, plus mechanical, electrical, and plumbing openings and equipment requirements.

Can NBE help during plan check?+

NBE can address structural plan-check comments for documents within its scope and coordinate required revisions with the project team.

What can affect the structural system for a multi-family building?+

Story count, unit and parking layouts, spans, site and geotechnical information, fire and acoustic assemblies, material preferences, seismic requirements, and construction approach can all affect the feasible system. NBE evaluates those inputs with the project team rather than selecting a system from unit count alone.

What should I send for an initial review?+

Send the site address, jurisdiction, available architectural or concept plans, project size, current phase, and any review comments or known structural constraints.

Find the structural decisions your multi-family project needs next

Share the project address, plans, unit program, and current phase. NBE will review what is available and identify the appropriate next engineering step.
