Timing matters in planning, and archaeology is often treated as urgent only when a submission date is already close. The time needed for a desk-based assessment depends on the complexity of the site, the availability of record data and how clear the proposal is when the consultant starts. In most cases, the quickest route is not to rush the report itself but to start early enough that the right information can be assembled properly.
What influences the timescale
A simple site in a relatively low-risk area can usually be assessed faster than a complex site in a sensitive historic location.
- The size and complexity of the site affect how much evidence needs to be reviewed and interpreted.
- Historic settlement cores, scheduled monument settings or landscapes with dense archaeological records often require more time.
- Clear plans and an accurate project description help because the assessment can focus directly on the real form of development.
- Data requests, archive review and site access can also affect the programme.
Why early instruction saves more time than fast turnaround
The apparent delay is often not the writing of the DBA but the point at which the issue is first identified.
- If archaeology is raised only at validation stage, even a quick report can still disrupt the overall planning programme.
- Commissioning the assessment earlier allows the findings to inform design and supporting documents rather than chase them.
- It also gives room for any follow-on work to be considered realistically if the site proves more sensitive than expected.
- A slightly earlier start usually creates a smoother application than a last-minute rush.
How to help the process run efficiently
Clients can speed up the assessment by providing the consultant with clear, accurate project information from the outset.
- Supply a site location plan, red line boundary and a concise description of the proposal and likely groundworks.
- Share any previous reports, historic information or planning correspondence that may already exist for the site.
- Raise any programme pressures early so realistic priorities can be discussed.
- Avoid changing the scope mid-report if possible, as new layouts or ground disturbance details may alter the conclusions.
Frequently asked questions
Can a DBA be prepared urgently?
Sometimes, depending on workload and site complexity, but quality should not be sacrificed just to produce a quick document.
Will complex sites take longer?
Yes. Sites with dense heritage records, uncertain boundaries or multiple heritage issues often need more detailed review.
Should I wait until my drawings are finalised?
Usually not. Early archaeology input is often more efficient because it can inform the design before the application pack is locked.
Need advice on this type of project?
If you are working to a planning timetable, AS Archaeology & Heritage Services can advise on likely desk-based assessment timescales and the information needed to keep the process moving efficiently.
