JCT80 is the same idea when it comes to keeping score on the value of variations. The new game is called The Contractors' Price Statement . Variations are very popular. They are the strawberries and cream of every construction site. First, the client is invited to change his mind, have a longer building, have another floor, have a pitched roof instead of a flat one, have a swimming pool instead of a car park.
Builders love variations.
The first bash of the tennis ball in this new JCT game is when a variation instruction is given by the architect. And, assuming it is a real variation. Attached to the statement is the contractor's price for the variation, any calculations of consequential loss and expense, and any adjustment to the time for completion of the works. This isn't a tennis ball, this is a cannon ball. Within 21 days of the price statement ball, the employer's QS, after consultation with the architect, sends a quaint reply ball.
