ᐅ Optimal Timing for Installing Utility Connections to a New House

We are purchasing a plot of land. The utility connections (water/sewage/electricity) still need to be installed; the pipes and cables are not yet on the property and must be laid from the immediately adjacent street to the plot.

When is the best time to carry out this utility connection?

1. Before the actual house construction?
2. After the shell construction?
3. At a later stage?

I am especially unsure regarding sewage because the exact elevation level of the house has not yet been determined.

If there is no basement, wastewater must be installed before the foundation slab. Water, gas, and electricity connections can only be brought into the house once you have installed windows and at least one lockable construction door.

Construction water and temporary power must be ensured before the shell construction begins. These need to be applied for, then the tradespeople will eventually show up. Before that, they wouldn’t have lifted a finger at our site.

Utility connections are installed once the heating system is in place.

You should install the shafts for wastewater and, if applicable, rainwater drainage during the initial earthworks. Connection to the public sewer system is usually done later, when the related work won’t cause disruptions. This tends to block the driveway, depending on the location and accessibility of the plot.

Water and electricity will only be available once the building is sealed.

Site electricity is typically needed for crane setup. We used water from containers, so no separate connection was required.

You should apply for all permits as early as possible, including telecommunications. Utility connections can take a long time.

General contractors usually point this out.

Before backfilling the basement, all connections were completed since the work area had to be filled in for the prefab house scaffolding.

Despite registering on time, EnBW postponed several appointments, citing "illness and vacation" as excuses, which endangered the installation date. Only after pressure was applied to the contractor did they respond.
