Quality control (QC) is the part of quality management that ensures products and service comply with requirements. It is a work method that facilitates the measurement of the quality characteristics of a unit, compares them with the established standards, and analyses the differences between the results obtained and the desired results in order to make decisions which will correct any differences. Technical specifications define the type of controls that must be carried out to ensure the construction works are carried out correctly. They include not only products materials, but also the execution and completion of the works.
Quality assurance is a set of planned and systematic actions to ensure that products and services comply with specified requirements. It not only involves checking the final quality of products to avoid defects, as is the case in quality control, but also checking product quality in a planned way in all the production stages. It is the development of work and product design procedures to prevent errors from occurring in the first place, based on planning backed up by quality manuals and tools. When a consensus has been reached on the requirements of a quality management system, it is possible to define a series of generic standards applicable to any type of organisation. The international standards, generically called ISO 9000, are the most widespread and generally accepted in developed countries. The ISO 9000 standards consists of four basic interdependent standards supported by guides, technical reports and technical specifications

Construction Materials Testing (CMT) primarily involves testing structural materials used to build new projects from the ground up, materials and components used to construct new additions or new components being added to an existing facility. These include earthwork, shallow and deep foundations, destructive and non-destructive concrete testing, wood construction observations, structural masonry, structural steel, sprayed-on fireproofing, Exterior Insulation and Finish Systems (EIFS), roofing evaluation and testing and asphalt pavement evaluation and testing.

OSHA was signed into law on December 29, 1970 in order to protect workers from unsafe work conditions. It was estimated that 14,000 workers were killed on the job in 1970, but as of 2009 that number has dropped to approximately 4,349. During that time span U.S. Employment has almost doubled and includes over 130 million workers. Doliveira Systems clearly sees a correlation between worker safety and a successful project and strives for excellence in safety on every job with no area taking higher precedence. Our project superintendents and project managers are certified in OSHA safety standards to ensure it's implementation on every work site.
