    Erection is the manufacturing end of the plant

    Installation is setting it up in any location where it is to be used

    Commissioning is making an over all examination of the plant installed

    Erection is preparing the physical side of the site for the new piece of kit and fitting it in place. Installation is the preparation of the kit for working, filling with oil, connecting up air ducts, intercabling etc. Commissioning is the final act before putting the new piece of kit into use, it often involves testing the kit as an individual piece and checking that its fully integrated into its final system. i.e. a new generator has got working protection and change over alarms which work with the existing switch board.

    Installation of a system or machinery up to the point of being able to start running is erection.
    Commissioning is preparing for running or taking into use of the installed system or machinery by making preliminary tests and checks (pre-commissioning) and initially running the system or machinery or taking it into use while checking and setting all of its running parameters in accordance with its design (hot commissioning).

    Commissioning is a term that spans a wide range of general meanings. Most of the time it refers to Building Commissioning, or HVAC System Commissioning.

    Building commissioning is the process of verifying, in new construction, that all the subsystems for HVAC, Plumbing, Electrical, Fire/Life safety, Building Envelopes, Interior Systems (example laboratory units), cogeneration, utility plants, sustainable systems, Lighting, Wastewater, Controls, and Building Security achieve the owner's project requirements as intended by the building owner and as designed by the building architects and engineers. Building commissioning is a quality-focused process necessary for both non-complex and complex modern construction projects.

    But "Erection and Commissioning" is quite a bit different. It typically refers to larger construction of industrial plant systems and equipment.

    "Erection and commissioning" primarily refers to the installation and professional oversight of major industrial plant facilities and large equipment installation by qualified design engineering companies, etc. This type of Erection and Construction Commissioning activities may include oversight of construction of Oil Refineries, Rolling Mills, Reheating furnaces, Galvanizing lines, Annealing Furnaces, fabrication and erection of towers, piping, hydraulics, or the erection of giant steam turbines, power generators, etc. These "erection and commissioning" activities require specialists with a proven track record as these may be very expensive $50 Million projects, that require intense detailed oversight. There is no room for mistakes in that size of project. If someone specs the wrong size piping, or wrong steel, this delays the entire project, and may become million dollar mistakes.

    It is necessary to dovetail the commissioning aspect of these projects right into the construction activities. The "Erection and Commissioning" agents must take responsibility for the correctness of the design documents, checklists, and the delivery of the plant equipment as well. So the entire "erection and commissioning" process is an integrated on-going process.

    After the erection of the plant and large equipment, then the equipment needs to be properly "commissioned" by well-experienced seasoned professionals. This is especially critical for large very expensive energy utilization equipment, such as natural gas turbines and compressors. These final commissioning activities include verifying construction phase tests, and commissioning testing.

    The ultimate goal of the commissioning processis to deliver to the owner, a project that is on schedule, has reduced first cost of delivery, and substantial life cost reductions, and meets the needs of the user and occupants, including a fully operational and optimized plant and systems.

    It means erection is the process of preparing / making / building the place (where the new machine or plant would be installed) according to the product that would be installed at that place / site

    Installation is the process in which machine's different single parts are connected with each other to become a single working machine (or plant) it also includes the mechanical joints & connections and also the electrical joints and connections

    Commissioning is the process in which after installation we test the machinery (or plant) its every operation whether its working fine or not

    Am i right ????
