FedAl,
TS 22002 is the prerequisite program requirements of FSSC 22000.
Clauses 4 and 5 of TS 220002 cover the construction and layout of buildings (4), and the Layout of premises and workspaces (5).
Basically the TS 22002 is concerned with making sure that you have the basic fundamentals of food safety established before you worry about producing safe food. It want's to make sure you have a safe and hygienic facility.
For documentation of clause 4 you could have a policy that all buildings will be constructed within the guidelines of the section in areas that 4.2 describe.
For example you are not going to put a food factory downhill from a cow pasture as rain water would cause cow fecal matter to flow down the hill and into your factory area. (environment TS 20002 4.2).
4.3 wants you to have clearly identified boundaries. That could be a fence line around your perimeter or no trespassing signs.
From what I've seen you should have policies for every section of the code even if it's not directly telling you to have documentation for it. However there is always documentation you can make. You can have a perimeter inspection form to check the perimeter of a fence line to ensure it has not been breached (cut). It's all in how you want to document your system.
Does that make sense? Does that put you in the right direction or do you need more information?
