This group includes application of physical laws and principles in the design, development, and utilization of machines, materials, instruments, structures, processes, and systems. Services of this type involve the provision of designs, plans, and studies related to engineering projects.

This service code includes

1. the application of physical laws and principles of engineering in the design, development and utilization of machines, materials, instruments, structures, processes and systems for waste management projects like engineering services related to household garbage collection and disposal systems, such as recycling facilities, composting facilities, transfer stations, resource recovery facilities, landfill sites;

2. engineering services related to programmes for the collection, treatment, recycling, and disposal of industrial air, water and solid wastes, generally to a level such that the remaining waste stream can be safely released to the natural environment or ordinary municipal systems;

3. engineering services related to programmes for hazardous waste remediation, such as management of nuclear waste, chemical agent destruction, brownfield redevelopment, groundwater modeling, contaminated site remediation.

This service code also includes

1. the application of physical laws and principles of engineering in the design, development and utilization of machines, materials, instruments, structures, processes and systems for water treatment and distribution systems, sewer systems, sewage treatment plants and drainage projects like engineering services related to systems for the collection, distribution, treatment, and disposal of water such as drinking water distribution systems, pumping stations, reservoirs, water storage facilities, water transmission and distribution mains including dams used primarily for local drinking water distribution and desalination plants;
