Construction Site Waste Management — Planning & Swap-Outs

A construction site produces predictable waste: strip-outs first (old fixtures, insulation, drywall), then frame waste (timber offcuts, concrete), then fit-off (packaging, plaster, minor debris). Plan your bin sizes upfront and schedule swap-outs around your build phases — email booking lets you change dates without drama.

Separating waste streams (concrete separate from timber, metal separate from general debris) cuts landfill fees and keeps your job compliant with SA EPA rules. Prohibited items like asbestos or batteries derail a whole bin.

The three phases: strip-out, frame, fit-off

Strip-out (Week 1–2): remove old fixtures, insulation, drywall, internal walls. Lightweight, bulky, fast.
Frame (Week 3–4): demolition waste, concrete cutting, formwork, timber offcuts. Heavier, more mixed.
Fit-off (Week 5+): plaster, painting, final details. Light debris, packaging, small offcuts.

Each phase produces different waste. Plan separate bins if possible — a strip-out bin (15m³, lightweight) differs from a frame bin (20–30m³, heavier). Fit-off can often share space or go to a smaller bin.

Bin sizing: typical guidance per phase

A new residential build (strip-out + frame + fit-off) typically needs 3 bins across the schedule. A commercial renovation of a multi-storey building needs larger bins and more frequent swaps — 30–40m³ bins every 7–10 days.

Build phase	Typical bin size	Included disposal	Why
Strip-out (whole building)	20–30m³	3–3.5t	Bulky, lightweight; high volume, lower weight
Frame & demolition	30–40m³	3.5–4.5t	Concrete, timber, formwork; heavy, requires large bin
Fit-off (final trades)	12–15m³	2–2.5t	Light waste; packaging, plaster, minor offcuts
Ongoing (mixed)	30m³	3.5t	Running bin for a multi-week site; smaller swap-outs as phases progress

Email-based swap scheduling

Most construction sites work via email. You email us before your 7-day hire ends with new bin dates, and we swap within 24 hours (or by your specified date). No phone tag, no surprise callouts.

Example: "Day 6 of hire — strip-out nearly done, frame crew arriving Monday. Swap out Friday 2pm, swap in Monday 7am." We confirm, collect Friday, deliver Monday. Simple.

Give us 48 hours' notice where possible, but 24 hours works. If you're a repeat contractor, we can set standing swap schedules (every Monday and Friday, or every Wednesday, etc.).

Separating waste streams to cut disposal cost

Mixed waste goes to general landfill. Separated waste goes to specialist facilities: timber to recycling, concrete to crushing, metal to scrap. Disposal fees vary — mixed waste costs more.

Plan: (1) concrete and heavy inert (separate bin); (2) timber (separate bin if volume warrants); (3) metal (collect and haul separately or mix with timber); (4) general (drywall, insulation, packaging).

Concrete alone — a foundation strip or old slab — can be 20–30 tonnes per site. A separate 30m³ bin dedicated to concrete saves thousands in mixed-waste disposal cost. Timber framing also separates easily if bundled as you demo.

Compliance: prohibited items and subbies

SA EPA rules: no asbestos, liquids, tyres, batteries, hazardous chemicals, e-waste, or medical waste in your bin. A bin rejected at the facility for prohibited items costs you a callout fee and disposal charge.

Brief subbies upfront: plumbers, electricians, and painters must not drop batteries, paint tins, or e-waste into the bin. Collect hazardous waste separately or have subbies haul it themselves. Make it a condition of the site.

Asbestos is non-negotiable — it must be removed by a licensed contractor before it reaches your bin.

Site Supervisor Guide — FAQs

Can I swap out my bin mid-hire if the site phase changes?

Yes — email us anytime before your 7-day period ends, and we'll swap within 24–48 hours (or your specified date). No charge for swaps within your hire period; you just pay for the new bin if it's a different size.

Should I separate concrete from timber waste?

Yes, if the volume warrants it. Concrete disposal is cheaper than mixed waste. If you have over 5–10m³ of concrete (a foundation strip, old slab, or significant cutting debris), a dedicated concrete bin saves money. Otherwise, mixing is fine.

What size bin should I book for a strip-out?

20–30m³ is typical for a house or multi-room strip-out. Strip-outs are bulky (drywall, insulation, fixtures) but relatively light. A 20m³ bin is often enough unless the building is large or heavily fitted (kitchens, bathrooms, cladding). Email photos if unsure.

What happens if a subbie puts batteries or paint into the bin?

The facility will reject the bin. You'll be charged a callout fee to remove the prohibited items, then resubmit the bin. Brief all subbies before work starts: prohibited items (batteries, paint, e-waste, asbestos) do not go in the bin.

How do I coordinate bins for a multi-month build?

Plan ahead: email us at the start with your expected phases and swap dates. We'll confirm each swap via email 48 hours before. If you're a regular contractor, we can set a standing schedule (e.g., every Monday and Friday swap-outs).
