Autocad model fix - repost

A very quick fix of an existing model - some gaps require fixing and some small elements added + preparing in a particular level format. We estimate 2 to 3 hour's work, but our Autocad staff are not here over the weekend. Would need one check and then done! Needed to be completed within 48 hours from posting. Then, if available there is a second piece of work that will be offered after quoting on the same basis. This is due the following day and is a small new modelling exercise of a crane - 2d information supplied. Please quote for the first part separately. Thank you
