Why housekeeping is part of the work
Clearing debris is written into the construction safety orders. Title 8 section 1513 requires form and scrap lumber with protruding nails, and all other debris, to be kept reasonably cleared from work areas, passageways and stairs. Combustible debris inside the building or structure is removed promptly as the work goes on, and all waste is disposed of at intervals set by the rate of accumulation and the capacity of the job site container.
Some of the waste on a site cannot share a container with the rest. Flammable and hazardous wastes go into covered containers kept separate from the normal debris, and solvent waste, oily rags and flammable liquids are held in fire resistant covered containers. Scrap lumber, waste material and rubbish are taken out of the immediate work area as the work progresses.
How a site is swept decides what the crew breathes. Title 8 section 1532.3 applies to construction work except where exposure stays below 25 micrograms of respirable crystalline silica per cubic metre of air, sets the permissible limit at 50 micrograms as an eight-hour time-weighted average, and does not allow dry sweeping or dry brushing where that could add to exposure, unless wet sweeping, filtered vacuuming or another method that lowers the risk is not feasible. Concrete cutting, grinding and slab work put dust into the same air.
What leaves the site is also a stormwater question. Modesto's construction best practices require dumpsters to be covered and maintained, and never cleaned by hosing them down on site where the wash water can enter the storm drain system. Excess concrete, sealants and paints are never washed into a street or storm drain, and waste materials are never buried or left in the street.
What construction cleanup includes
The work areas, passageways and stairs are walked and cleared as the trades finish each stage, with form and scrap lumber pulled out first because of the nails in it. What comes out is stacked by stream at the same time rather than piled and re-sorted later.
Combustible debris inside the building is removed promptly while the job runs, so a floor under fit-out does not carry a fuel load through the night or the weekend shutdown.
Flammable and hazardous wastes go into covered containers of their own, and solvent waste, oily rags and flammable liquids into fire resistant covered containers.
Silica dust is wetted or taken up with a filtered vacuum, and nothing is dry swept or dry brushed where that would add to what the crew is breathing.
Nothing is thrown from a building into an area where people may be unless the area is guarded and signed.
At completion the site is cleared of debris, the containers are emptied and covered before they travel, and the tickets from each stream go into the job file.
Construction cleanup is debris work. It clears the material the trades leave behind and takes it off the property by stream; the detail cleaning that hands a suite to a tenant is a separate scope and is not described here.
Where construction cleanup is needed
Occupied retail centres
A fit-out next to trading units puts debris on a shared walkway, so passageways and stairs are cleared between stages rather than at the end of the week.
Office floors under fit-out
Packaging, offcuts and ceiling tile build up fast on a single floor, and combustible debris comes out promptly while the rest of the building stays occupied.
Tilt-up warehouses
Slab cutting, grinding and patching put silica dust across an open floor, so it is wetted or vacuumed instead of swept.
Apartment and HOA renovations
Unit turns run one after another with residents in the building, and scrap lumber with protruding nails is the first thing off a shared landing.
New subdivisions
Scrap builds on every lot as the trades move through, and the containers are emptied at intervals set by how fast each lot fills them.
Restaurant and kitchen fit-outs
Packaging, casework offcuts and sealant and paint containers come out together, and the flammable and hazardous items travel in covered containers of their own.
Questions about construction cleanup
At intervals set by the rate of accumulation and the capacity of the job site container, which is the test Title 8 uses rather than a fixed day. Combustible debris inside a building is removed promptly while construction goes on, and scrap lumber, waste material and rubbish leave the immediate work area as the work progresses.
No. The scope here is debris: what the trades leave behind, sorted and taken off the property with a ticket for each stream. Window cleaning, dusting and turnover cleaning are a different scope, and nothing on this page describes them. The written estimate says what is included before the crew is booked.
Not where that could add to silica exposure. Title 8 allows dry sweeping and dry brushing only where wet sweeping, filtered vacuuming or another method that lowers the exposure is not feasible, and sets the permissible limit at 50 micrograms per cubic metre as an eight-hour average.
Modesto's construction rules say a dumpster is covered and maintained, checked for leaks, and never cleaned by hosing it down where the wash water can enter the storm drain system. Waste materials are not buried and not left in the street.
Same day or within 1 to 2 days, depending on urgency and availability. Morning or afternoon arrival windows, confirmed when the estimate is booked. The interval between rounds follows the rate the job produces debris.
Construction cleanup by city
Construction cleanup is requested through the construction debris page for that city, where the receiving arrangements and the local diversion rule are covered.
