STEEL BUILDING INSTALLATION

Choose an experienced independent erection team, appoint your own contractor or assemble your ESB building with detailed drawings, an interactive 3D model and remote support.

INSTALLATION OPTIONS

Choose the Right Route for Your Project

ESB supplies a complete building package that can be installed by an experienced independent erection team, your own appointed contractor or through supported self-assembly.

Experienced Independent Erectors

ESB can introduce reliable independent erection teams that have each assembled hundreds of our buildings. Their erection quotation, scope and payment terms are agreed separately with you.

Your Own Contractor

You can appoint your own competent steel erector or building contractor. We provide the construction drawings and technical information needed to identify and assemble the building correctly.

Supported Self-Assembly

Our fully bolted system is suitable for capable customers who want to assemble their own building. Stamped components, construction drawings and an interactive 3D model help show exactly what goes where, with ESB available for remote guidance.

THE ESB BUILDING SYSTEM

Designed to Go Together

ESB buildings are engineered as complete structural packages. The steel frame and rigid bracing are bolted together, giving every manufactured component a defined position and purpose.

Each member is stamped so it can be identified against the construction drawings. An interactive 3D model provides an additional visual reference, making the erection sequence and location of individual components easier to understand.

  • Fully bolted structural frame

  • Rigid steel bracing rather than wire bracing

  • Stamped, cross-referenced components

  • Construction drawings and interactive 3D model

PROFESSIONAL ERECTION

Arrange the Right Team for the Build

ESB supplies the building package, drawings and technical information. Erection can then be arranged through an experienced independent team or a competent contractor appointed by you.

ESB-Experienced Independent Teams

  • ESB can introduce a small number of reliable independent erection teams

  • Each team has assembled hundreds of ESB buildings

  • They are familiar with our fully bolted system and construction drawings

  • Erectors can often assist with unloading when arranged in advance

  • Availability, scope, price and payment terms are agreed directly with the erection team

Your Appointed Contractor

  • You remain free to choose your own steel erector or building contractor

  • The contractor should be competent to erect the specified steel building system

  • ESB provides the relevant drawings and component information

  • Your contractor confirms the labour, plant and safety arrangements they require

  • Delivery, unloading and the erection start date should be coordinated in advance

Any erection team introduced by ESB operates as an independent contractor. Their quotation and contractual arrangements are separate from the ESB building supply quotation.

INSTALLATION PROCESS

How a Steel Building Comes Together

The exact erection method depends on the building, site and appointed contractor, but most ESB buildings follow the same broad sequence.

GETTING STARTED

01

Delivery and Setting Out

The building package is unloaded and stored safely. The completed base, holding-down positions and building dimensions are checked before erection begins.

02

Columns and Main Frames

Columns, rafters and haunch connections are assembled and raised in the planned sequence, with the frame stabilised as work progresses.

03

Bracing and Secondary Steelwork

Permanent bracing, purlins, side rails, eaves beams and other secondary members are installed to complete the structural framework.

04

Roof and Wall Cladding

Roof sheets or insulated panels are fitted before the wall cladding, together with any specified rooflights and condensation-control components.

05

Doors, Gutters and Flashings

Door components, gutters, downpipes, trims, flashings and other agreed accessories are installed around the completed envelope.

06

Final Checks

The installer checks the building alignment, connections, fixings, seals and finishing details against the drawings and agreed scope.

The appointed erector must follow the project drawings, suitable erection procedures and their own site-specific safety arrangements.

SITE READINESS

Prepare the Site Before Erection

The building should only be scheduled for erection when the base, access and agreed site arrangements are ready. Delays or dimensional problems discovered after the team arrives can create additional costs.

Base and Project Readiness

  • Complete the concrete base and allow it to achieve the required strength

  • Check the finished dimensions, levels and holding-down positions against the drawings

  • Obtain any necessary planning and Building Control approvals

  • Approve the final construction drawings before manufacture and erection

  • Report any dimensional discrepancy to ESB before installation begins

Site and Contractor Readiness

  • Provide safe access for the erection team, delivery vehicles and plant

  • Keep the working area clear, firm and suitable for the required equipment

  • Confirm unloading, lifting equipment and competent operators

  • Arrange any required welfare, temporary power, fencing and waste facilities

  • Coordinate the delivery date, installer availability and proposed start date

ERECTION SCOPE

Check What Is Included in the Erection Quote

Installation requirements vary between projects. The independent erector’s written quotation should clearly identify their work, equipment and site requirements before a start date is agreed.

Confirm in Every Quotation

  • Erection of the steel frame, bracing and secondary steelwork

  • Installation of roof and wall cladding

  • Fitting of doors, rooflights, gutters, flashings and trims

  • Labour, supervision and expected installation duration

  • Required lifting equipment, access plant and operators

  • Delivery unloading or offloading assistance

  • Travel and accommodation where applicable

Commonly Outside the Scope

  • Groundworks, concrete bases and holding-down alterations

  • Incoming utilities, drainage and electrical connections

  • Internal blockwork, partitions and finishing work

  • Welfare facilities, fencing, skips and temporary services

  • Additional work caused by an inaccurate or incomplete base

  • Specialist plant, delays or return visits not included in the quotation

Only the written quotation issued by the appointed erector determines the exact installation scope and exclusions.

SUPPORTED SELF-ASSEMBLY

Clear Information for Capable Self-Builders

Self-assembly can be a practical option for customers with suitable construction experience, equipment and help available. The ESB system is fully bolted, with each structural component designed for a specific location within the building.

Members are stamped so they can be cross-referenced against the construction drawings. The interactive 3D model provides another way to view the frame, connections and component positions—often making the system feel like “giant Meccano”.

Pre-Build Checks

General arrangement and construction drawings
Stamped and cross-referenced structural members
Interactive 3D building model
Complete building fixings supplied as specified
Remote advice and support from ESB

The customer remains responsible for competent labour, suitable lifting equipment and safe working arrangements throughout self-assembly.

Timescales are influenced by:

Building size and specification
Single-skin or insulated cladding
Number of doors, openings and accessories
Site access and lifting requirements
Base accuracy and site readiness
Weather and available working space

COST AND TIMESCALE

Planning the Installation Budget

Erection is priced separately from the ESB supply-only building quotation. The final cost and programme depend on the building specification, site conditions and the scope agreed with the independent erector.

Indicative Erection Cost

As an early budgeting guide, professional erection commonly costs approximately 20–30% of the building supply value.

Smaller buildings are often nearer 30%, while larger projects may be nearer 20%. Plant, travel and accommodation are often included, but this must be confirmed within the installer’s written quotation.

This percentage is guidance only and is not an installation quotation.

How Long Will Installation Take?

The appointed erector will confirm the expected programme after reviewing the project.

SITE SAFETY

Safe, Competent Erection Must Be Planned

Steel building erection involves substantial structural members, lifting operations, work at height and a frame whose stability changes as construction progresses.

The appointed contractor must plan the erection sequence, use competent personnel and provide suitable equipment, supervision and site-specific safety arrangements.

Before Work Begins

Confirm the planned erection sequence
Plan temporary stability and progressive bracing
Check that cranes, access plant and ground conditions are suitable
Prepare lifting arrangements and controlled working areas
Plan safe access, fall protection and emergency procedures
Keep the current construction drawings available on site

The client and appointed contractors must understand and fulfil their respective health and safety responsibilities throughout the work.
