Chapter Review
Summary■
■ The correct location on the building site must be identified before the foundation or slab
can be constructed. ■
■ Laying out a building involves locating the outside corners of the foundation,
driving stakes, and then stretching building lines between stakes to mark where the
walls will be. ■
■ Measuring tapes can be used for layout work, but leveling instruments are more precise.
Leveling instruments are also used to establish grades and elevations. ■
■ Laser levels are replacing conventional transits and levels in building site layout.
Their biggest advantage is requiring only one person to take measurements, rather
than two.
