Restoration after sewer work
Putting back the surfaces and features disturbed by the work.
A driveway, a lawn, a patio, and a finished basement floor are four different restoration problems. A proposal saying "restore disturbed areas" has not addressed any of them.
What this page cannot establish
- SewerOwner cannot establish whether restoration after access or excavation is appropriate for your property
- this approach cannot establish that a restored surface will match the surrounding area
- this approach cannot establish that settlement will not occur later
- this approach cannot establish that an omitted surface is included
What it attempts to do
Return disturbed surfaces to a stated condition after the work below them is complete.
When contractors may discuss it
These are circumstances in which the approach comes up, not a checklist that makes it correct. There is no situation in which one method is universally right.
- whenever excavation or access pits are part of the scope
- when hardscape, landscaping, or interior finishes sit above the work
What has to be known before applicability can be judged
If a proposal for this work is priced without these, it is priced against assumptions. That is not necessarily wrong — but the assumptions should be written down.
- which surfaces the work will disturb
- what standard each surface will be restored to
- whether any surface is excluded from restoration
- who performs each part of the restoration
Access and site considerations
- different surfaces carry very different restoration expectations
- backfill and compaction affect how the surface behaves later
- some restoration may be seasonal
What to clarify in a proposal for this work
These are the details that most often differ between two proposals for what sounds like the same job.
- a surface-by-surface list of what is restored and to what standard
- what is explicitly excluded
- whether backfill and compaction are described
- whether the finished surface is expected to match the surrounding area
- who is responsible if the surface settles later
- timing, where restoration cannot happen immediately
What to keep afterwards
- photographs of each surface before work
- the written restoration scope
- photographs after restoration
Alternatives worth asking about
Asking why one approach is proposed rather than another is a reasonable question, and the answer tells you what the contractor believes about your line.
Traditional excavation
Digging along the line to expose and replace pipe directly.
Expose the line so that pipe can be removed and replaced, and so that what is uncovered can be observed directly.
Cannot establish: the condition of any section outside the excavation; that no further conditions exist elsewhere; that the new installation will perform for any stated period.
Pipe bursting
Pulling a new pipe along the existing route while displacing the old one.
Replace the pipe along its existing route by drawing new pipe through while the existing pipe is displaced outward, using pits rather than a full-length trench.
Cannot establish: that the route is suitable without site-specific assessment; the position of other buried services; that this method is preferable to any other for a given property.
What would change the answer
- which surfaces the work will disturb
- what standard each surface will be restored to
- whether any surface is excluded from restoration
- who performs each part of the restoration
What to do next
Restoration is where two proposals for the same excavation most often differ by thousands, and where the difference is easiest to miss.
