Property development Step plan

Subdivision works: earthworks, roads, sewerage and landscaping

When a subdivision is carried out, the site is made ready for building: earthworks, roads, sewerage, landscaping and water management. Each step needs its own working drawings, permits and certificates. In Lean they are attached to the step where they are needed, and for each housing development you see what is already in and what is still missing.

Why subdivision works take so much information

The works on a subdivision lay the foundation for everything that follows. The ground is excavated, levelled and prepared, the roads and sewerage are laid, and the green areas are planted. If this is not done according to the drawings and the permit, every home in the subdivision feels the consequences.

That is why the site crew has to work with the right version of the working drawing, the environmental permit must be in order before the works start, and every sewerage inspection certificate must be easy to find later, per home. Often a soil survey report and the insurance of the works belong to it as well.

With IRP in Lean ERP you record the works as a sequence of steps, with per step the information that belongs to it. Below is an example of such a step plan. You can model your own processes within IRP.

Step plan: carrying out a subdivision

An example of the groups and the information that belongs to them. Most documents belong to the subdivision, the sewerage inspection certificate to each home separately.

  1. EarthworksThe earthworks lay the basis for the foundations and the infrastructure: excavating, levelling, preparing the ground and making sure the site is stable and safe. For that, the permit and the drawings must be in order. This group holds the environmental permit, the working drawing of the earthworks at subdivision level, the working drawing of the roads and the sewerage inspection certificate per home.
  2. Landscaping and water managementGreen areas and water have their own place in the subdivision, often with conditions from the permit. This group holds the landscaping and planting plans, and the water management file.

Subdivision or home: each document at its level

The working drawings of the roads and the earthworks belong to the subdivision. The sewerage inspection certificate belongs to each home separately, even though it is drawn up while the subdivision is carried out. It is needed again at the handover and the sale of that plot.

In Lean, subdivision, blocks and plots are in one structure. A document is recorded once, at the right level, and is visible wherever it is needed. For each process you see how many documents have come in. A certificate that has not come in is shown as missing, not as an empty box that nobody notices.

Following up the works on site

The earthworks and the road construction are carried out with work orders per project step, assigned to a crew, a person or a subcontractor. A subcontractor can see his work orders through a portal, with the documents. What he sees is set up with you at the start.

On site, the crew takes photos with their phone on the work order and records the hours. Read more under Site management and Planning.

When several subdivisions are running at the same time, management sees them all in one planning. That shows where the works on one subdivision could hold up the next.

Frequently asked questions about subdivision works

What do subdivision works involve?

In this example: the earthworks, laying the roads and sewerage, landscaping and water management. In Lean you record these as steps of a process, with per step the drawings, permits and certificates that belong to it.

Where is the sewerage inspection certificate kept?

With the home it belongs to. It is drawn up during the subdivision works, but it is needed later at the handover and the sale of that plot.

Can a subcontractor see his work in Lean?

Yes. Through a portal with his own user he sees his work orders as a list or a calendar, with the documents. He only sees what concerns him. This is set up with you at the start.

The complete step plan for property development

Once the subdivision works are done, the site is ready for building. Then the construction phase of the blocks starts.
