Re: halld-collab : jLab Hall D Staffing Needs
Hi Elliot
Good summary.
You all ( ya'll) should also estimate the installation , construction and
commissioning bump in the manpower.
As the penultimate bump hunters this should be easy.
The manpower estimate must include the extra term staff that will be required
during the peak period of construction.This will probably be considered as a
construction cost as it will consist of term , contract and contracted labor.
Basically a purchased item.Purchased labor which Physics still uses , is
still considered as a construction cost at JLAB.
I have attached my complete labor estimate which includes my first guess of
permanent project technical staff and the temporary staff hired
forconstruction.
Peruse and use as you see fit.
Thanks
Paul
