MES is the only construction agency in the country which carries out all construction related tasks like construction of residential and office buildings, hospitals, roads and runways, marine structure like docks and harbours across the country including border areas. Besides conventional buildings, MES is largely involved in the construction of sophisticated and complex laboratories, factories and workshops, hospitals, airfields, runways and hangars, dockyards, wharves and other marine structures. It also deals with all the multifarious associated requirements such as air-conditioning, cold storage, electric and water supply, sewage treatment and so on. Most important of all, the facilities, assets and infrastructure created are maintained in a serviceable state and, in some cases, operated too, by the MES.
