In order to develop the most practical and economical methods, it is in this area that it is hoped the leading manufacturers of scaffolding can be of assistance in the development of better methods of enclosure for cold weather work.
In the actual construction of wall-bearing buildings, particularly those with more than one or two stories, the mason contractor and the general contractor must coordinate their operations to an even greater extent than they do now. Even more efficient techniques of bricklaying, materials handling, scaffolding and job scheduling are going to have to be used if the economies inherent in wall-bearing construction are to be achieved. Good job supervision by qualified personnel will be most essential, as will a certain measure of quality control in the selection of materials, the batching and mixing of mortar and in achieving the quality of workmanship that will make certain that the strengths for which the walls were designed are obtained. The importance of proper supervision of the construction of engineered designs cannot be minimized.
The repetitive "leap frog" operation of building "story height" bearing walls and then installing the floor system before the next story can be built will require careful job scheduling and the coordination of all trades. The use of the Critical Path Method of scheduling can be of great help in maintaining a tight schedule and eliminating possible bottlenecks or trouble spots before they occur.
Wall-bearing construction of the type discussed in this series of publications is not an impractical "dream." For a number of years, wall-bearing brick structures with heights up to 15 or 16 stories have been designed and built in Europe, where economy and the conservation of materials have been of the utmost importance. The traditional American construction industry's "know-how" and ability to organize and operate jobs efficiently can certainly be applied to make this construction technique a practical reality here also. The materials, the design knowledge and the construction know-how are available to do the job.

Your laborers can move loads like this with a PRIME-MOVER MASON TENDER. Here is a basic handling device for mason contractors that handles either packaged brick or palletized brick also stone, block, tile and mortar. The two-section mast raises the load 7' 6" (8' 6" optional). It retracts to clear the doorways, and tilts to engage, carry, and discharge loads. This machine is made to traditionally high Prime-Mover standards for long, trouble-free, profitable performance.
Ask your dealer to show you how easily your hod carriers or laborers can operate this new Model 1-812 mason tender. You can use this machine on all of your jobs to cut costs of handling all sizes and shapes of masonry materials.
