Once the shell is finished, cladding and roofing can be installed. At the same time, the electrical and plumbing contractors start running pipes and wires through the interior walls, ceilings and floors. See below how plumbing, electrical and heating is installed by Ace Kind.
Drainage pipes, as well as water supplies for each fixture, are installed.
Ductwork is installed for the heating, ventilation and air conditioning (HVAC) systems if required. Heating pipes are installed for radiators and / or under floor heating systems.
An electrician then installs wiring for sockets, lights and switches. Wiring for telephones, TV and music systems is included in this work.
Note that HVAC ducts and plumbing are usually installed before wiring, because it’s easier to run wires around pipes and ducts than vice versa.
