In the course of construction and restructuring of unique buildings and structures, any architect
faces the need to design complex surfaces that have curvilinear geometrical forms that cannot be
neglected. In turn, designs with complex curvilinear geometrical forms require higher skills in their
development, as the complexity of their design and implementation is a lot higher than that of elements
that have flat surfaces.
The value of plaster cannot be underestimated. Plaster applied to surfaces of various buildings
and structures (walls, partitions, columns) flattens the surface, shapes it up and protects it from
moisture and fire; it improves resistance to heat transfer; it reduces air permeability and improves
the soundproofi ng properties of protected designs, etc.
All pre-set parameters of plaster are to constitute the subject of random inspections, and inspection
results are to be considered in the course of acceptance of any work. The most important
though hard to control parameters of plaster include:
bond strength, thickness, moisture content and density;
flatness or its radius of curvature;
deformation properties of the plaster layer versus deformation properties of the design.
Control over compliance with the design is hard to implement as curvilinear surfaces are located
at a significant height above the ground and/or the floor level. Therefore, there is a need to develop a
non-destructive method of quality assurance of construction, restructuring and finishing works.
The solution to the problem becomes possible due to development of specific hardware and
software designated for remote though accurate identification of the surface curvature.
The authors have developed a modified range-oriented laser methodology that employs angular
segments to remotely assess the flatness of the building structure and its radius of curvature and
to determine the deviation of its value from the designed one. The software also makes it possible
to implement the quality control of the work performed over the curved surfaces coated with various
types of plaster.
The proposed solutions have been pilot tested in practice, and they are ready for use in the
building industry, namely, in construction, repair and restructuring works.
