Tolerances and workmanship for the construction of reinforced masonry wall is important to provide required strength and aesthetics appearances to structures.
Construction technology has been evolved and developed over years however; masonry constructions that have been practiced for many years are still man made art.
To achieve required structural integrity and planed aesthetic appearances of reinforced masonry structures, different tolerances are established and therefore should be considered during construction.
Almost all reinforced masonry construction materials are produced to specific tolerances similarly; approximately entire masonry members are constructed and built to determined tolerances.
Since, masonry is an exposed construction materials, that is why more strict tolerances might be imposed on masonry structures compare with those limitations that are imposed on other structural systems which are ordinarily protected inside after the construction is finished.
All tolerances pertained to the installation of masonry members are specified in Building Code Requirements and Specification for Masonry Structures (ACI 530.1-11) except for the tolerances which are determined in the contract document.
The purpose of providing placement and contraction tolerances by ACI 530.1-11, is to protect and safeguard the performance of the structure. However, the designated values in ACI 530.1-11 is more than enough for achieving normal aesthetic aspiration.
It is possible to impose more strict tolerances in the project records to manufacture an acceptable and more aesthetically appealing masonry structure.
It should be known that not only applying more rigid and tough construction tolerances could increase construction expenses but also make the work substantially difficult and considerably complicated.
In this article specified tolerances which are included in ACI 530.1-11 and are necessary for construction of reinforced masonry structure will be discussed.
