Structural Design and Alteration Coordination

What the scope can include

Select the work and handoff your project needs. The agreement identifies the included deliverables and responsibilities.

• Investigations and design criteria

  Collect existing drawings, field observations, intended loads, geotechnical information and equipment data. Identify conditions needing exposure, survey, testing or specialist investigation before analysis relies on them.

• Foundations and primary structures

  Coordinate the structural design scope for foundations, retaining elements, framing, slabs and building systems. Connect the engineer’s calculations and details with architectural geometry, civil grades and building services.

• Alterations and component interfaces

  Address bearing-wall changes, openings, additions, equipment supports, stairs, canopies, connections and delegated components. Establish which professional designs each component and how it attaches to the primary structure.

• Repairs and temporary conditions

  Coordinate damage assessment, strengthening and repair documents, shoring, underpinning, excavation support and erection or lifting interfaces where included. Temporary works and monitoring require their own responsible technical direction; construction methods remain with the assigned contractor.

Prepare for the assignment

You can start with incomplete records. Tell us what is available and what still needs to be established.

• Information to bring

  Available structural drawings, site access, proposed openings or loads, equipment cut sheets, prior investigation reports and geotechnical records. Identify urgent damage concerns for appropriate professional evaluation.

• The agreed handoff

  A coordinated structural input register, agreed design/calculation and drawing package from the responsible professionals, and tracked technical responses within the contracted scope.

Decisions, fees and timing

Scope and dependencies determine the proposal. No universal price or approval date is assumed.

1. Confirm the basis and responsibility

   Review the available records, intended endpoint and authority to use the information. Assign missing inputs, technical decisions and the parties who can authorize changes.

2. Coordinate and review the work

   Prepare the included documents from agreed inputs, resolve interfaces with responsible specialists and track revisions. Record external decisions and conditions separately from work prepared for review.

3. Account for project-specific dependencies

   Unknown existing construction, new loads, ground conditions, investigation access, temporary works and changes after the design basis is established.

4. Deliver the defined milestone

   Provide the controlling documents and remaining-action record. Identify what is accepted, what still requires a decision and what belongs to a separately contracted next stage.

Load-bearing walls, beams and structural openings

Removing a wall, replacing a beam or cutting an opening changes how forces pass through the building. Define the proposed opening and retained structure before a responsible structural professional evaluates the solution.

• Wall removal and beam replacement

  Bring framing plans, photographs, proposed opening dimensions and information about floors or roofs above and supports below. An evaluation must address load paths, bearings, columns, connections and foundation effects, with exposure or testing where records are insufficient. Coordinated calculations and details can then define the selected alteration; an assumed wall type cannot establish that removal is feasible.

• Openings through floors, roofs or walls

  Locate the opening against actual members, reinforcement and building services. Supply penetrations, equipment and access requirements so the designer can coordinate framing/edge details and affected fire or weather barriers. Temporary support and the construction sequence need assigned responsibility before cutting. Continue with remodeling or equipment scope below once investigations and design dependencies are identified.

Repair and stabilization need a diagnosed condition

Foundation repair plans, underpinning, balcony repair and structural damage assessment address different problems. Document the observed condition and define the professional investigation before choosing a repair method.

• Damage assessment and foundation repair

  Provide dated condition photographs, movement or leak history, previous repairs, structural drawings and soil/drainage information. The responsible specialist determines the inspection, measurements and testing needed to distinguish symptoms from causes. An assessment documents findings and investigation limits; repair design develops the selected corrective details and permit documents. Neither step alone is the physical repair.

• Underpinning and staged support

  Underpinning modifies or extends support beneath an existing foundation. It needs existing footing and load information, ground investigation, access constraints and effects on nearby structures or utilities. The responsible professionals determine whether it is suitable and specify the design, sequence interfaces and monitoring needs. Coordinate excavation and temporary support separately; underpinning is not a generic substitute for every foundation repair.

• Balconies and related enclosure work

  For balcony repair, document supports, connections, slab/deck condition, guards, waterproofing and drainage, including inaccessible areas. Structural and enclosure specialists coordinate causes of deterioration and repair interfaces. Drawings, temporary access/protection and inspection requirements support partner-performed field work; track completed repairs and unresolved findings in the closeout record.

Mezzanines, metal buildings, canopies and stairs

Secondary structures still depend on the main building, site and intended use. Assign the manufacturer, specialty designer and building professional’s responsibilities before component drawings are relied upon.

• Mezzanine permit plans

  Provide the proposed use, floor area, storage/equipment loads, height and connection layout. Coordinate floor framing, columns and foundations with stairs, guards, accessible access and exit arrangements. The output can combine structural calculations/details with architectural and life-safety interfaces; a supplier’s platform drawing does not settle every building or occupancy question.

• Metal-building foundations and canopies

  A metal-building foundation needs the manufacturer’s geometry, column reactions, anchor information and load basis coordinated with geotechnical findings. Canopy plans need dimensions, supports, attachments and applicable loads, plus drainage and building-envelope interfaces. Identify who designs each connection and foundation; supplier information must be reconciled with the actual site and local review.

• Stair and guard design

  Supply floor levels, openings, available headroom, intended use and attachment conditions. Coordinate stair/landing geometry, guard and handrail details, structural loads, exits and accessibility with the appropriate professionals. Fabrication/shop drawings and installation remain assigned scopes; structural details should match the architectural circulation plan before release.

Permanent equipment supports and temporary engineering

An equipment-load evaluation concerns the specified equipment and support conditions. Temporary shoring and crane support assessment require their own construction-stage information and responsibility; permanent building drawings do not automatically cover them.

• Equipment loads and rooftop supports

  Provide operating and shipping weights, support reactions and the equipment footprint. Include center-of-gravity information where relevant, vibration data and attachment requirements. For rooftop equipment, coordinate curbs, openings, framing, access and waterproofing with mechanical and electrical services. The responsible designer evaluates members, connections and load paths, then develops the agreed support details. Total equipment weight alone does not establish capacity.

• Temporary shoring and crane support

  Shoring needs the supported structure, loads, installation/removal stages and ground or floor capacity. Crane support needs the actual crane configuration, outrigger/crawler reactions, setup location, underground hazards and ground information from the responsible parties. Coordinate support engineering with the contractor and lift team. Engineering documents do not replace equipment setup, lift planning, supervision or operator responsibilities; construction is performed through the assigned partners.
