Laying masonry is an art and a great deal of practice. However, the sense of satisfaction gained from doing a job well is worth the effort. This chapter is designed to help you master the proper techniques used in laying several common types of brick walls. 12.1 Basic Operations A number of basic operations must be mastered before a masonry structure can be built. These basic operations include planning and preparing the site, spreading mortar, holding a brick, using both hands at the same time, forming a head joint, cutting brick, leveling and plumbing brick, and using a mason’s line. Much prac- tice is needed to master these operations. 12.1.1 Planning and Site Preparation Prior to any masonry work being performed, the construction company plans for the materials to be used during the construction project. An estimator determines quantities and then orders required materials for the project. The supervisor has the materials delivered to the construction site when preparation has concluded and the site is ready for work to begin. As for the brick, keep in mind there are many different types, sizes, and color selections that can be chosen. Some may take a few weeks to be delivered, others may take a month or longer depending on the type, uniqueness, and quantity selected.
