Steel Construction

To eliminate re-work and prevent heat distortion, the team evaluated four critical geometry factors before shop fabrication:

A major risk item involved thin infill mesh welded to substantial structural frames. Heating thin sheet metal alongside heavy section steel releases residual stresses unevenly, causing severe buckling. Following industry best practice, the team separated the galvanising process: galvanising the main structural frame and infill mesh independently before assembling them using approved mechanical fasteners. This eliminated thermal distortion while ensuring 100% zinc coverage across all hidden contact surfaces.

Practical Rule: Never assume specifying ‘galvanised finish’ in contract documents guarantees buildability. Prior to order placement, obtain formal confirmation that fabrication shop drawings have been fully reviewed for galvanising access, venting, and drainage.

While EXC2 is appropriate for the vast majority of standard building frames, blanket upgrades to EXC3 unnecessarily inflate fabrication costs, welding oversight, and project timelines.

Key Insight: Targeted specifications save money. If standard building frames only require enhanced material origin tracking, add a specific traceability clause to EXC2 rather than upgrading the whole building to EXC3.

On a fast-track industrial warehouse development spanning three distinct erection zones, we resolved a classic conflict between workshop efficiency and site installation sequence. Workshop managers naturally prefer long, unbroken runs of identical assemblies, whereas site erection crews require complete sets of columns, bracing, and connections to erect a stable structural bay.

In this scenario, each of the three erection zones featured repeated roof trusses, heavy columns, and lateral bracing. 

If the workshop fabricated all roof trusses for all three zones consecutively to minimise jig setups, Zone 1 erection would grind to a halt because its accompanying columns and bracing components were still waiting in the fabrication queue.

To protect both shop repetition and site progress, steel fabrication scheduling was split into three distinct management decisions:

True delivery control requires tracking the complete production chain, including non-destructive testing, protective coatings application, paint curing times, bundle packing, and final dispatch. By stamping distinct assembly marks that identified both the production batch and site delivery package, progress reviews shifted focus from overall tonnage to actionable site readiness.

Site Scheduling Rule: At weekly production meetings, stop asking ‘How many tonnes did we weld?’ Instead ask: ‘Which missing item is currently blocking the release of the next erection package?’

In designing a multi-bay logistics distribution facility, Novelty Structures conducted an early-stage value engineering review to strike the perfect balance between structural weight, mill material availability, connection repetition, and waste reduction.

A common design misconception is that the lightest calculated steel frame is automatically the cheapest and most sustainable. In reality, specifying dozens of slightly different section sizes, unusual sub-grades, or custom hole patterns drastically increases purchasing lead times, workshop handling effort, and steel offcuts.

While rationalising member sizes saves workshop labour, over-standardising by specifying a single heavy section across the entire building unnecessarily increases steel tonnage. The project team successfully achieved a balanced design, optimising total steel weight, raw material availability, fabrication efficiency, and scrap reduction.

Sustainable Steel Principle: Economical steelwork isn’t just about reducing weight. True efficiency comes from early coordination between structural design, material supply routes, standard connection details, and stock cutting lengths.
