Install/Labor time

JimmyJam Member Posts: 78
We average 2.7 hrs per 300' loop including stapling or tying, install manifold and pressurize to 60PSI here in Minnesota! (slab on grade application over existing insulation)

NOTE: This includes loading, unloading and reloading.

We average 1 "manhour" per 100' of joist tubing installs in preexisting joist track plates. (using 3 installers). For example we just installed 633' of 3/8 pex in 6.75 manhours last week with drilling of some holes through joists, terminating at manifold and pressurize.

I am sure HotRod does it quicker however.

    Install/labor time

    I know there are alot of variables but how do you estimate time for tubing installs in concrete, joist space heating, and above floor applications. I know this is a broad subject, but even some little comments would be appreciated. I don't want this to become a bragging contest on how fast or thorough you are, so if you do not want to put it on the forum please contact me through direct email.

    Are you asking this question from the standpoint of providing estimates to your customers, or are you a homeowner curious about how long it should take to do something??

    Has labor calculators for various materials and equipment. I don't know if they are up to date with in-floor installs but it may be worth a try.

    My PHCC labor factors are very old and customized by doing cost accounting. When you cost account you do a very complete breakdown of labor and material per system ex:

    Underground waste and vent

    Aboveground waste and vent

    Undeground water

    Abovegrade water


    Misc. (bid time,travel,administration etc.)

    Heating insulation belowgrade

    Tubing placement

    etc. etc. etc.

    Good cost accounting not only allows you to customize labor factors, it is your barometer for how the job is going. We updated our cost accounting weekly to watch our projects carefully. The job end summary would give you all the indicators you need to determine strengths and weaknesses.

    Smaller shops don't usually go through these exercises as they have a good feel for labor costs and lack the clerical manpower to take time for cost accounting.
