Question 1

What size is a typical industrial shed in the City of Casey?

Accepted Answer

Around the Hallam, Lynbrook and Lyndhurst industrial estates, most builds are 12×24m through to 30×60m portal-frame. Wall heights 5.4m to 7.5m to clear a forklift mast with a pallet, two or three roller doors (4.0m wide × 5.0m high typical), one PA door per side. Mezzanine roughly 30-40% of floor area is common for office, lunch room and small parts storage. Site coverage is regulated under the property's planning zone — Industrial 1 (IN1Z) is the most permissive, allows around 70% site coverage.

Question 2

Portal frame vs C-section — when do I need portal frame?

Accepted Answer

Move to portal frame (hot-rolled UB/UC columns and rafters, welded knee braces, base plates) the moment any of these apply: clear span over 12m; wall height over 5m; mezzanine load over 3kPa; overhead crane or hoist; commercial Class 5/6/7/8 occupancy; insurance / lender requires certified industrial construction. C-section is great for sheds up to 12m clear span and 4.2m wall — almost every farm shed and garage in Casey. Once you're building for trucks and forklifts, portal frame earns its premium.

Question 3

What does an industrial shed permit look like in City of Casey?

Accepted Answer

Industrial sheds in IN1Z, IN2Z or Commercial 1 (C1Z) zoning typically need both a building permit AND a planning permit, plus stormwater detention design, EPA-compliant bunding if any fluids are stored, and a Class 7b (warehouse) or Class 8 (workshop) occupancy certification rather than the Class 10a a domestic shed gets. Total approval timeline 8-16 weeks depending on objections to advertising / planning. We work with three Casey-region commercial surveyors regularly and manage the application end-to-end.

Question 4

Do you fit out the mezzanine and the office space?

Accepted Answer

We build the shell, the mezzanine steel framing and floor decking (Bondek or structural ply), the stair to mezzanine, the roller doors, the PA doors, gutters and downpipes, three-phase rough-in to a sub-board location, and rough plumbing to a wet area location. Lining out the office (gyprock, ceiling, carpet, partitions, kitchenette, toilet block fit-out) is generally done by a separate commercial fit-out contractor — we'll happily recommend one and stay engaged through their works, or quote it as a separate package.

Question 5

Wind loading — what classification covers Hallam and Lynbrook?

Accepted Answer

All of City of Casey is Region A (non-cyclonic) under AS 1170.2. Most flat industrial-estate sites in Hallam, Lynbrook and Lyndhurst are Terrain Category 2 or 3 — protected by surrounding buildings, low exposure. We typically design to N3 (W41m/s) which is the practical equivalent for a 6m-eave industrial shed in those estates. Open rural-edge sites or freeway-fringe ridgelines (some Berwick lots) push to N4. The engineering certificate states the exact design wind speed and category — included on every quote.

Question 6

How long from order to occupancy on a 20×40m industrial shed?

Accepted Answer

Realistic timeline: 4-6 weeks design and engineering, 8-14 weeks planning and building permits (varies wildly with objections), 6-10 weeks steel lead time from BlueScope and the local hot-rolled merchant. Slab pour and 28-day cure for industrial-load slabs (150-200mm). Erection 3-4 weeks for the shell. Mezzanine, doors, services 2-3 weeks. Total: 7-10 months from signed contract to occupancy permit — aggressive timeline, but achievable with clean planning.
