The direct answer

Structural Alterations: what matters most?

Structural alterations demand a controlled sequence: verify what is supported, install temporary works, form adequate bearings, place the designed steel or lintel, and only then transfer load and make good.

Our first survey focuses on the variables that change method, risk and price. The written scope then states the included work, important assumptions and the information or approvals still required.

Typical scope

What we can include

  • Load-bearing wall removal
  • RSJ and steel beam installation
  • New door and window openings
  • Temporary support and sequencing
  • Padstones, bearings and masonry repairs
  • Coordination with Building Control

Every site is different. The quotation—not a generic web list—defines the final package.

Devil in the detail

Four issues worth resolving before work starts.

Good planning makes risk visible while there is still time to change the method.

01

Unverified structure

Ceiling direction, hidden beams, chimneys and upper walls need checking against the design assumptions.

02

Temporary stability

The building must remain supported throughout—not only once the permanent steel is installed.

03

Services in the wall

Electrical, plumbing, heating and drainage routes can change the sequence and scope.

04

Fire & finish details

Steel protection, junctions, floors and ceilings must be completed to the approved specification.

How the work progresses

A six-stage route from question to handover.

The exact construction changes; the discipline of resolving information before burying it does not.

  1. 1

    Review structural design and approvals

  2. 2

    Survey structure, access and services

  3. 3

    Plan temporary works and protection

  4. 4

    Install support and form openings

  5. 5

    Place steel, bearings and connections

  6. 6

    Inspect, protect and make good

Plan with better information

Use a calculator, then let the site visit replace assumptions.

Our tools organise quantities and project details without pretending to be a quotation. Results make the first survey more useful.

Frequently asked

Structural Alterations questions

Clear answers before commitment make the survey, quotation and build easier to compare.

Do I need a structural engineer?

For load-bearing alterations, normally yes. The engineer specifies the permanent structure and may advise on temporary works. Building Regulations approval is also usually required.

Can we stay in the property?

Often, but dust, noise, service disruption and temporary access can be significant. We agree a practical separation and protection plan first.

How long does wall removal take?

The structural sequence can be relatively short, but preparation, steel lead time, service diversions, inspections and finishing affect the full programme.

Can you install steels supplied by others?

Potentially, provided the steel matches the approved design and the lifting, access, bearing and connection requirements are clear.
