Method and apparatus for construction layout

An apparatus for locating layout detail during construction layout, the apparatus comprising:

• a marker base comprising:
• a base member;
• a weighted mount attached to the base member and having a top side and a bottom side;
• and
• a connector supported by the marker base and projecting from the top side and away from the bottom side;
• a measuring instrument secured to the marker base, the measuring instrument comprising:
• a disk secured to the marker base between the base member and the bottom side of the weighted mount;
• and
• a ruler extending radially from the disk.

A method of performing construction layout, the method comprising:

• establishing a reference point with a detail locating apparatus having a marker base having a vertical axis, a measuring instrument secured to the marker base and extending beyond an edge of the marker base and away from the vertical axis, and a prism assembly mounted to and extending vertically from the marker base and disposed coaxially with the marker base on the vertical axis;
• receiving, by an electronic surveying instrument, at least one offset distance to a defined point relative to the reference point, the defined point associated with at least one wall;
• receiving, by the electronic surveying instrument, a description associated with the defined point;
• and
• locating, with the measuring instrument, a wall mark location associated with a first wall of the at least one wall and marking the wall mark location based on the description.
