Loadbearing Masonry Construction
(Continued from page 19)
lected to go for the normal 8 inch high units since it would have been slightly less expensive. High stress 8 x 8 x 16 standard units for this project cost 30 cents each (514 now). Split-face texture one side and standard face the other, cost 38 cents each (564 now). Combed face units, one or two sides, cost 34 cents each (514 now). Of course the six inch high unit is a good alternative to using 4 inch high units in exposed conditions which is normal to California. The 8 inch high units exposed on the interior without texture, scoring or other treatment, tend to show their individuality allowed by production standards in a not too flattering way. Four inch high units or even six inch high units, with no special texture, look fine.
Prior to construction of Barracks P-005 using four inch high units, exposed interior and exterior, other architects, not so familiar with the scale of individual units or how the wall actually looked in the sunlight, were specifying standard size block. After the Barracks, the Naval Facilities Engineering Command required the 8 x 4 x 16 units to be used.
Conclusions
This is what each of these loadbearing masonry projects have in common:
Based upon an average floor area of 10 to 12,000 square feet, about 90 percent of the building walls and floors were erected without scaffolding more than 4 feet high or minimum shoring during each 5 to 6 work day period.
No other structural system can match this accomplishment! The actual appearance during construction was of buildings being assembled or manufactured in place rather than merely constructed. Most savings of time were directly related to the mason and his construction, Electrical conduits rose vertically with the walls. As each floor is placed, it serves as an instant work platform for all trades without down time for work stoppage. With this team work effort the "on and off" problem is eliminated, contractors profits increase and owners can occupy the building sooner.
Each construction step was programmed in advance by the general contractor using controlled scheduling methods with the building team being lead by the general contractor and the mason contractor. When a trade starts on this type of project, it works steadily until its work is finished. Efficiency increases as the building moves to higher floors, thus contributing to economy of construction.
After observing almost 100 stories of construction, refining our methods with practical experience, contractors suggestions, analyzing the production costs and efficiencies, as well as considering owners' requirements we have concluded that "Modern Masonry" is a real breakthrough for construction of most type of buildings in the 4- to 17-story height range.
MASONRY wishes to thank John R. Mock for this very interesting and informative review of "10 Years Of Progress In Modern Loadbearing Masonry Construction". His analysis and evaluation of the various building techniques plus his many years of practical experience in the field make this article a must for all those involved in the total building process.
