A 1978 Tenant Improvement With Three Days to Mobilize
You are the GC for a 4,200 sq ft office tenant improvement in a building constructed in 1978. The scope includes demolishing 1,200 sq ft of painted gypsum board, removing 800 sq ft of 9 in by 9 in vinyl floor tile, and cutting out about 40 ft of pipe insulation in a mechanical closet. The owner wants demolition to start Monday, three days from now. The dumpster is staged 15 ft from a storm drain inlet in the parking lot, and the crew plans to wash out the concrete truck and their tools in that lot. Two laborers will be paid $23 per hour as 1099 independent contractors with no workers' compensation certificate on file; the owner's broker asks only for a certificate naming the owner as additional insured.
1. What has to happen before any demolition begins, and what is your exposure if you start Monday as requested?

Three days is not enough, and the schedule is not a defense.
Asbestos. Renovation and demolition of a 1978 building require an asbestos inspection by an accredited inspector before disturbance. The suspect materials here are not incidental: 9 in by 9 in vinyl tile (and its mastic) in that era is very frequently asbestos-containing, and mechanical pipe insulation of that vintage is a classic ACM. If the inspection confirms asbestos, the work triggers the federal NESHAP regime administered in Minnesota by the MPCA: notification to the agency before the work starts (on the order of 10 working days ahead), handling by a licensed asbestos contractor with trained workers, and specific work practices and disposal.
Your exposure if you start anyway: as the GC you are the party that ordered the disturbance. Penalties for improper demolition of regulated asbestos material are per-day and can be substantial, the debris makes the dumpster and the site a regulated waste stream, the building owner and lender get dragged in, and your general liability carrier will look hard at whether you knew or should have known. The two laborers doing the tear-out are the people breathing it.
Correct sequence: engage the inspector now (it can often be done in a day or two), get the report, and if ACM is present, bid and schedule the licensed abatement before demolition. Tell the owner in writing that the Monday date is not achievable and why - that letter protects both the schedule and the relationship.
2. The dumpster sits 15 ft from a storm drain and the crew intends to wash out concrete and tools in the lot. Evaluate the environmental controls needed.

Every drop that hits that lot and runs to the inlet discharges to a municipal system or a water body, and construction Sediment and concrete washwater are pollutants, not dirty water.
Concrete washout. Washout water is highly alkaline (pH can exceed 12) and is toxic to aquatic life. It must go to a designated, lined washout container or an excavated pit that is pumped and disposed of properly - never to a storm drain, a ditch, or the ground. If there is no room for a lined washout, arrange offsite washout or a portable containment service.
Tool washing and general runoff. Provide a contained wash station with settlement, and keep it away from the inlet.
Dumpster placement. Move it or protect the inlet. Minimum practice: reposition the dumpster, install a berm or inlet protection (filter fabric and stone, or a manufactured sediment guard), and cover or tarp the dumpster. A 15 ft offset with a graded lot gives runoff a direct path.
Permit threshold. Disturbance here is well under an acre, so the state construction stormwater permit may not apply on its own - but local erosion and sediment control ordinances and the site's own drainage patterns still govern, and a spill to the inlet is a release you will be reporting either way.
Document it. Erosion and sediment control inspection log, washout location noted on the site plan, and a brief SWPPP-style narrative even if not strictly required. It costs an hour and answers the question before it is asked.
3. Assess the labor classification and insurance posture for the two $23/hour laborers.

Treat this as high risk and fix it before mobilization.
Classification. Paying construction labor by the hour, on your schedule, doing work you direct, with your tools and your materials, and issuing a 1099 does not make them independent contractors. Minnesota applies a statutory test to construction workers that looks at factors such as whether the worker has an independent business, maintains a separate business location, holds himself out as a business, has his own tools and equipment, is responsible for his own liability insurance and workers' compensation, and can realize a profit or loss. Two general laborers paid hourly fail most of these on their face.
Consequences of getting it wrong: unpaid workers' compensation premiums with penalties, unpaid unemployment contributions, unpaid withholding, and personal liability for the officers who signed off - plus the risk that both workers are treated as your employees for a claim that arises on the job.
Insurance gap. The broker asking only for an additional-insured certificate is asking the wrong question. Before either laborer sets foot on site, obtain proof of workers' compensation coverage - theirs, if they are genuinely independent, or put them on your policy. Also verify their general liability limits; a certificate naming the owner does not transfer the obligation to carry coverage.
Practical fix: put the two laborers on payroll as employees, or contract with a legitimate staffing or subcontracting firm that carries its own workers' comp and general liability with adequate limits. Price the job with that cost in it. Buying labor at $23 an hour with no coverage is not a discount, it is an unfunded liability you are carrying for the owner and for the workers.
