2). A concrete slab of uniform thick-ness can be placed by positioning the screeds at the high and low points of the cambered beam. The weight of the concrete slab would then cause the cambered beam to deflect to a level plane at the speci-fied eleva t i o n . Sounds easy, but the trick is to de-t e r mine the amount of beam cam-
