[200William-EC SP67851] SP67851 Marquis Re: Water Testing Western Rooftop Terrace

[Matt Perkins]

Thanks Darren,
  Sarkis What is the next step. We have finished our requirement under 
the agreement at mediation.  Should we contact the owner of 601 and ask 
what his intentions are given there is no evidence his apartment is 
leaking.
