Class Code Information


Concrete Construction – NOC – All Operations to Completion

Includes foundation or the making, setting up or taking down forms, scaffolds, falsework or concrete distributing apparatus. 

Not available for division of payroll with Code 5222 “Concrete Construction in Connection with Bridges or Culverts – All Operations to Completion” and Code 6235 “Oil or Gas Well – Drilling or Redrilling – All Operations to Completion & Drivers” at the same job.


Code 5213 applies to employers engaged in all types of commercial concrete building construction, self-bearing floors, foundations, piers, grain elevators and silos.  This classification includes making and erecting forms, placing reinforced steel and stripping forms.  The employer will set up the “foundation forms,” pour concrete into the forms and then level the concrete smooth.  They will then disassemble the forms after the cement has dried. These “foundation forms” are usually small wood barriers that hold the cement into the form for whatever the employer is making.  Self-bearing floors are self-supported concrete floors elevated above ground.

Another operation contemplated under this classification is the erection of concrete slabs using the “lift” method.  This operation involves the pouring of concrete slabs on the ground and then hoisting them to the top floor using hydraulic jacks to position columns which will hold up each floor.  The floors will be erected starting from top, working their way down.  When the floors are lifted to the correct height, steel beams will be installed to hold up the concrete floors.

This classification includes guniting operations and waterproofing by means of spray gun, concrete gun or other pressure apparatus.
