Ever wonder why house plans are sold in sets of 5, 8 or 12? Extra sets are expecially nice as construction begins and you need them to get bids from various subcontractors quickly. They are also nice to have during construction because your home plans will be put through adverse weather conditions, as well as exposure to concrete, mud, and heavy paperweights (framing nailers and whatnot) to keep them from blowing away. Some people like to get one set of houoseplans laminated to leave on the job. This is a great idea, and will keep the plans ledgible during construction. Laminating is fairly cheap and can be done at your local copy shop. Now, all you have to do is keep the subs from walking off with the house plans so that your other subcontractors can use them during construction.
