Geometry
Overall length, width, required clear span, roof form, height, support positions and architectural intent.
ZABALERALARGE-SPAN ARCHITECTURAL STRUCTURES
TECHNICAL CENTRE
Engineering starts with the design basis.
Large-span structures are not selected from one span number or one generic loading table. The structural pathway is established from the project geometry, governing criteria, environmental exposure, operational loads and local engineering requirements.
DESIGN BASIS
Define what the structure must resist before defining what it looks like.
The inputs below form the starting technical brief. Not every project needs every criterion, but none should be assumed without review.
Gravity loads
Self-weight, roof build-up, live load, maintenance load and project-specific suspended equipment.
Wind
Site wind criteria, exposure, pressure coefficients, uplift, local cladding loads and stability system.
Seismic
Project seismic basis, structural mass, support conditions, connection behaviour and local engineering review.
Snow / rain
Snow where applicable plus rainfall, ponding, drainage capacity and roof geometry.
Operational loads
Scoreboards, lighting, AV, sports equipment, catwalks, services, solar and other project-specific loads.
ENVIRONMENTAL EXPOSURE
Durability is a design input, not a finish selection.
Large structural systems can be exposed to dramatically different environments. Protective strategy is set around location, internal conditions, maintenance access and intended life rather than copied from a previous project.
Coastal & marine
Salt deposition, wetting cycles, drainage, crevices and maintenance access affect material and coating strategy.
Aquatic & humid
Pool halls add humidity, condensation and chlorides. Internal and external exposure may require different solutions.
Tropical & high rainfall
Rainfall intensity, humidity, drainage, biological contamination and coating maintenance require explicit review.
Industrial / aggressive
Airborne contaminants, process emissions and cleaning regimes can materially change the protection system.
ENGINEERING DELIVERABLES
Agree the document package before fabrication.
The exact project deliverables are confirmed in the supply scope. The target technical package can include the following where applicable and verified.
Structural design basis and agreed governing criteriaGeneral arrangement drawingsStructural calculations where included in the verified project scopeConnection and support detailsFoundation reactions / anchor information where includedFabrication and shop drawingsMaterial and protective-finish schedulesErection drawings / sequencing informationQA, inspection and material documentationPacking and export documentation
FABRICATION & QA
The factory package needs to remain traceable to the approved design.
Material control
Specified structural materials, certificates and project schedules are matched to the fabrication package.
Fabrication inspection
Welding, bolted connections, dimensions and protective finishes are inspected according to the agreed quality plan.
Export packing
Member identification, packing sequence, container or alternative freight strategy and unloading logic are coordinated before shipment.
Erection information
Installation sequencing, temporary stability and supervision scope are confirmed for the selected project rather than assumed.
EVIDENCE STATUS
Separate demonstrated experience from new-project verification.
This distinction keeps feasibility useful without turning historic project information into an unsupported promise for the next site.
01Available as project evidence
International project references
Current qualification material includes completed large-span, stadium, church, dome and high-wind project examples. Project references are evidence of experience, not blanket certification for a new site.
02Project confirmation required
Design standards
The governing standard is selected for the destination and project brief. Historic references to AISC, Australian standards and other codes do not automatically confirm approval for every new jurisdiction.
03Project confirmation required
Maximum practical span
Span depends on structural family, loading, geometry, supports and project conditions. ZABALERA does not publish one universal maximum-span promise.
04Project confirmation required
Corrosion protection
Coastal, aquatic, tropical and industrial exposure require an agreed coating, galvanising or material strategy tied to the actual environment and maintenance plan.
05Project confirmation required
Membrane systems
PTFE, PVDF and ETFE capability is only represented when the exact project system, supplier scope and supporting evidence are confirmed.
06Project confirmation required
Local certification
Local structural sign-off, building consent, fire, foundations, services and authority approvals remain jurisdiction- and project-specific.
PROJECT RESPONSIBILITY
Supply, engineering and local statutory roles stay explicit.
Apollo NZ Global operates as a wholesale and project-supply company. The agreed manufacturing and engineering package is coordinated with the project team, while local approvals, foundations, civil works, site erection, fire, services and statutory sign-off remain with appropriately qualified local parties unless expressly included in the verified project scope.
