Introduction
Experience continues to be the best guide for estimating the probable cost of any construction. Most contractors and engineers will have on file actual cost data for numerous jobs assembled and analyzed over a period of time and under varying conditions. Such information is invaluable and permits estimating new jobs with reliable accuracy. The prime purpose of this guide is to assist the individual who does not have the experience in estimating costs of concrete masonry walls nor access to case histories.
Modular Coordination
Concrete masonry walls should be designed and constructed with modular coordination to achieve maximum economy. Modular coordination is a forerunner to the popular modern concept, "Systems Building." It applies the principles of good management to the total building process by making use of full and half-length units so as to minimize cutting and fitting of masonry at the job site. Essentially, modular coordination means two things:
(1) The masonry units that go into a building are designed and manufactured so that they will fit together at the job site without alteration or cutting, and
(2) Building plans are dimensioned to standard modules to accommodate the size and design of modular building materials.
The module established for concrete masonry design is four inches. This
