Tco

[horsegoer]

What is needed when the spec says to participate in and provide labor for "off hours" testing of equipment and systems to obtain a temporary certificate of occupancy and final TCO?

What are the guys doing?

Thanks

Sounds like you need to make yourself available and on-site during off-hours (read: evening or weekend) so someone can comission some equipment. If it don't work, you get to fix it. Round and round you go until it's OK, then a temporary certificate is issued.

Sounds fun. I recently had to do that. It was a bar...:grin:

A "temporary certificate of occupancy" is a TCO, your final will be a CO.

We usually require testing of the illumination levels (e-lites and exit lighting)after dark, and depending if this is a partially occupied building, we may have to do acceptance testing of fire alarm systems, sprinkler tests, etc. after hours so as not to disturb "business".

I always tell the GC that he or she can bring whomever they want, as long as that person can operate the needed systems, but it would be a benefit if the EC is there to make any minor fixes or explain operation of inverters, location of devices, etc.. I'd rather not even have to right up a minor issue if the problem can be solved right there. The extra time for the afterhours is usually balanced by not having return trips for fixes.

I add some numbers into the price.

Testing and proving, depending on the occupancy and what's installed:
- FA
- Generators
- FA Pump
- etc

If the building is partially occupied, the other tenants may not appreciate horns and strobes blaring for hours/days.

Thanks , I understand off hours. I just, or still am, not sure of the scope of work involved when testing & commisioning is done. What isi testing and commisioning. Megger test etc.?????

[celtic]

Megger testing could be done during "on" hours....but looking for a TCO shortly after a wire pull is a bit of a swift action, no?

Depends on the equipment.

If it's a fire alarm, someone will go around and use a can of smoke on each smoke detector. Pull a couple pull stations. Make sure every horn & strobe is making noise and/or flashing.

If it's a back-up genny, the ATS may be tested for proper start-up and transfer, and check that all circuits supplied by the genny are energized properly.

As mentioned above, it may be night work to determine emergency egress lighting levels.
