Read the Evaluation Section:

Goal: The goal here is to identify:
1) Any hard requirements (e.g., “to win you must have a secret security clearance”)
2) Whether those hard requirements apply to subcontractors (whether those requirements “flow down” to subs)
3) Whether your business model aligns with the government’s priorities for this contract.

Finding the evaluation section: Like with the SOW section look for 
The Evaluation section headers:
1) Section M
2) Evaluation

And use keywords:
1) Factors
2) Low price technically acceptable
3) Best Value
