    HVAC Sequence of activities

    Hi everyone,

    Could you please explain me what the sequence of activities should be for HVAC installation in a commercial building. The building has a chilled water system (CH, CT, FCU) and perimeter hot-water heating using an electric boiler.

    Thank you!

    I would determine the answer during my quoting process.

    Agreed! But there is a typical order in which to do things.
    1. Install the CW and HW lines at the same time.
    2. At the same time another crew is usually installing the equipment in the mechanical room.
    3. The sheet metal guys are installing ductwork. The electricians are bringing in power to the units.
    4. The HVAC contractor installs the individual units.
    5. The control guys, sheet metal guys, the electricians and HVAC guys all try to work around each other to make final hookups to the unit.
    6. The service techs come in and make everything work. (Couldn't resist adding this as I have been a service tech for 1.2 million years)

    7. Modify duct work and re-reroute around fire sprinkler pipes because they always stick their pipes in your way and don't care because they are the biggest guy's on site.
