    Reminds me of project where heat reject from shopping strip A/C was under parking lot. Did it keep pavement clear of snow? Some years maybe.

    Then a well known engineer from those days tried to store snow for A/C.

    Now that is a JOB....and a great one at that!

    Knees hurt from looking at that....is there stand up and use tool to install cable ties for the pex?

    Was concrete pumped up from ground level? I see what might be mud piping/hoses.

    @JUGHNE thanks.
    I have 3 PexGun tools that tie the tubing to the mesh. Back and knees where definitely in pain for awhile after. Yes concrete was pumped from street up 8 stories.

    Very Nice, That's quite a job. 8 stories up takes a lot of planning especially in NYC

    @EzzyT- thanks. My ProPress tops out at 1-1/4” so I’m not familiar with the configuration of the large connections. Looks similar to the MegaPress. 

    Amazing work.

    @Mad Dog_2 thanks much appreciated, yes that would be nice.

    @Tom_133 I wouldn’t say anything one does should be easy, always willing to take on a challenge. If you do decide to take on a job anywhere that size let me know I’ll be willing to make the trip up.
    Thanks.

    Fantastic workmanship! It must have taken a day to purge all those loops.

    Was it design/build or did you have mechanical plans to work from?

    The mechanical rooms looks tight. Did you have any say on how large they should be or did you have to work with what they gave you?
    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    Two btu per sq ft for degree difference for a slab

    @Dan Foley thanks so much for referring this job to me much appreciated.
    @clammy it’s always a pleasure to work along side of you. There definitely was a lot issues we had to overcome on this one but we still knocked out of the park. 
    @Allislandradiant thanks.
    @mars_6 thanks.
    @Alan (California Radiant) Forbes there’s 7 manifold stations on this project that are split between 2 mechanical rooms.
    We pump in demineralized water and the glycol at the same time with my flush cart.
    We purged the system first with the boiler and system pumps running to get fluids mixing for some time. Then we purged the loops with the flush cart.
    It took a day for each mechanical to do that scope of work. 
    It was designed/build but we had to make some changes in order for everything late out how it did.
    I informed the contruction management company on the sizes of the mechanical rooms need to be and of course there was some push back.
    My approach to every job is that there has to be always going to be enough room for maintenance, repairs and equipment swap out in the future.
