Erection & Installation

Site teams deliver planning, site preparation, concrete works, and structural steel installation to sequence, alignment, and handover requirements.

Erection crews coordinate crane lifts, access constraints, and working-at-height controls to keep steel installation safe and on programme.

Service Overview

Our erection and installation service converts fabricated steel packages into safe, aligned, handover-ready structures on live project sites, including preparation and concrete scope where appointed.

Execution is built around pre-erection planning, daily sequencing, and verification of site readiness, concrete release, alignment, bolting, and snag closure.

Where required, we coordinate temporary works interfaces, lift studies, and phased handovers to support operating plants and constrained urban sites.

Process and Method Statement

  1. Step 1

    Pre-Erection Kick-Off

    We align on drawings, sequence, interface risks, and permit requirements with the site team before mobilisation.

    Handover point: Approved pre-erection plan and mobilisation checklist.

  2. Step 2

    Site Readiness Verification

    Site preparation, concrete works, access roads, crane pads, laydown zones, and concrete release status are verified against the agreed sequence.

    Handover point: Readiness and concrete release report with constraints logged and assigned.

  3. Step 3

    Lift Planning and Toolbox Control

    Lift plans are briefed with crews, roles assigned, and exclusion controls confirmed for each installation front.

    Handover point: Shift briefing records and daily lift release signoff.

  4. Step 4

    Steel Erection and Connection Closure

    Members are installed, aligned, and connection closure progresses from temporary stability to final bolting or welding requirements.

    Handover point: Alignment and bolt closure records.

  5. Step 5

    Snagging and Sectional Handover

    Touch-up, punch-list closeout, and sectional release are managed to avoid bottlenecks for follow-on trades.

    Handover point: Sectional handover certificate and snag closeout list.

  6. Step 6

    Final Handover and Documentation

    Closeout records are consolidated and issued in agreed format for client and principal contractor file completion.

    Handover point: Final steel installation closeout pack.

Quality, Safety, and Documentation

Our erection activities are run in alignment with client site rules, project specifications, and South African construction safety expectations for structural steel installation.

Standards and Quality

  • Project specification references to applicable SANS structural steelwork requirements, typically aligned with SANS 2001-CS1 scope
  • Engineer and principal contractor inspection hold points for alignment, connection closure, and handover
  • Construction compliance aligned with the Occupational Health and Safety Act and Construction Regulations applicable to site work

QA and Traceability

  • Connection method controls for bolted and welded joints per approved drawings
  • Weld procedure and welder competency records where site welding is required
  • Inspection signoff records linked to sectional handover

Safety and Site Compliance

  • RAMS and activity hazard controls prepared before each work front
  • Working-at-height controls, access checks, and rescue readiness integrated into task plans
  • Lift plans, exclusion zones, and communication protocols for crane operations
  • Induction and permit readiness for principal contractor site entry requirements

Typical Documentation Deliverables

  • Pre-erection checklist and mobilisation records
  • Site preparation and concrete completion records where in scope
  • Lift plans and daily briefing records
  • Alignment and bolting check sheets
  • Site welding and repair closeout records where applicable
  • Snag lists and sectional handover signoff
  • Final closeout report for client records

What We Need From You to Quote Accurately

Required for Pricing

  • Latest erection issue drawings and member marks
  • Confirmation of whether site preparation and concrete works are included in our scope
  • Site address, access route limits, and laydown availability
  • Concrete release dates and survey control status
  • Cranage plan or expected crane availability
  • Programme milestones and sectional handover dates
  • Site permit, induction, and safety file requirements

Helpful for Better Accuracy

  • Shift pattern and working hour constraints
  • Shutdown windows or live-plant restrictions
  • Temporary works responsibilities
  • Required reporting cadence for principal contractor meetings

Service-Specific Guidance

Pre-Erection Checklist

Clear pre-start responsibilities, including preparation and concrete scope, reduce site surprises and protect programme dates.

  • Client and contractor responsibilities for preparation and concrete scope defined
  • Cranage, laydown, and permit status confirmed before mobilisation
  • Concrete release and survey control checked before first lift

What Delays Erection and How We Prevent It

Most delay drivers are predictable when tracked early and managed daily.

  • Wind and weather triggers linked to revised lift sequence options
  • Missing bolts or late materials escalated through daily constraint logs
  • Access clashes resolved through planned interface meetings

FAQs

What must be ready before your erection team arrives?

If City Structures is appointed for site preparation and concrete works, we plan and execute that scope before erection. Where preparation is client-supplied, access routes, crane standing, laydown space, concrete release, and approved drawings must be ready. We issue a pre-erection checklist so responsibilities are clear before mobilisation.

Do you include site preparation and concrete works?

Yes, we can include site preparation, concrete works, and planning as part of the erection package when this scope is confirmed at quote stage.

Do you provide lift planning?

Yes. Lift planning is prepared to member weights, radii, and sequence, then briefed daily with crews and site supervision.

How do you manage working at height?

Working-at-height controls are integrated into RAMS, with access system checks, supervision, and task-specific rescue readiness aligned to site rules.

What causes erection delays most often?

Typical delays are wind restrictions, access constraints, late concrete release, missing bolts, and drawing changes. We reduce these through readiness checks, constraint logs, and early escalation.

Can you work in phased handover programmes?

Yes. We plan sectional handovers so following trades can start earlier while remaining steel areas continue installation.

Do you include snagging and touch-up before handover?

Yes. Snag closure and touch-up are tracked as part of sectional and final handover activities.

What records are issued at closeout?

Typical closeout records include readiness checklists, lift and alignment records, snag lists, and sectional handover signoff sheets.
