Cambridge City
Archaeology and Planning Conditions in Cambridge City
Within the city, sites are smaller, deposits are often deeper and better preserved, and the archaeological cost per square metre can be far higher than on a greenfield site outside it.
- Main cost driver
- Depth and complexity of deposits, not site area
- Main programme risk
- Archaeology interleaved with demolition and piling
- Typical method
- Targeted excavation plus attendance during groundworks
- Plan for
- Longer post-excavation assessment on multi-period sequences
Where the archaeological advice comes from
City centre sites frequently carry deep stratified deposits, and constrained working space changes the method as much as the archaeology does. Archaeological advice is again provided at county level, but the practical constraints — access, hoarding, crane positions, neighbouring structures — are what drive the programme.
How conditions are typically worded here
Conditions on urban sites often combine a pre-commencement written scheme with provision for continuing archaeological attendance during groundworks, because full prior excavation of a constrained site is sometimes impossible.
What the authority expects to see
A written scheme that omits any of the following is likely to come back, and a rejection costs weeks at the point in the programme least able to absorb them.

Questions
Common questions on this
Why is a small city site more expensive than a large field?
Because cost follows deposit depth and complexity rather than area. A deep, multi-period urban sequence takes far longer per square metre to excavate and record than a single-phase rural site.
Can archaeology run alongside our groundworks?
Sometimes, and on constrained sites it may be the only workable approach. It has to be agreed in the approved scheme and properly resourced, or it becomes a standing delay to the main contractor.
