you can find the tables (claims,contract and item) to normalize here with a few details to help you (there's nothing to download, copy and paste site) http://txtup.co/eaYSs

Consider:

tblContracts
contract number (PK)
description
division
district

tblBills
bill number (PK)
contract number (FK)
bill description

tblItems
item number (PK)
bill number (FK)
item description
unit
rate
place
quantity
date

tblClaims
claim number (PK)
bill number (FK)
