3.8 Unexpected
archaeological discovery insurance
In order to appreciate the need for the
above insurance it is necessary to understand the role played by archaeology in
the planning process, the potential losses that may be insured and the point at
which insurance cover should be sought. All these issues are dealt with below.
To a large extent the risks that the
developer runs can be identified, assessed and mitigated but, as explained, a
degree of risk is still left and it is this residue that may be insured.
3.8.1 The
process
The UK is very rich in archaeological
remains and much of it still lies undiscovered. This evidence of our past is an
irreplaceable national asset. It is protected by a host of legislation that is
designed to trace and preserve it. Archaeology is an essential part of the
planning process, a material consideration that cannot be ignored. Whereas some
archaeological sites are scheduled ancient monuments or otherwise protected
under specific legislation, most sites come under the government Planning Policy Guidance,
Note 16 (PPG16), on Archaeology and Planning. This is arguably
the most important publication relevant to archaeology and development in
England. PPG16 establishes procedures to ascertain the archaeological impact of
a development so that the planning authority can make an informed decision
about how best to safeguard archaeological interests. It rests on the principle
that archaeological remains are a valuable and finite part of our heritage that
should ideally be preserved in situ even if they are not scheduled. Basically,
it requires the developer to discuss the proposed development with the planning
authority and, if requested, to include relevant information with the planning
application. This often means that an archaeological study of the site has to
be commissioned and is where specialist commercial archaeologists such as MoLAS
(the Museum of London Archaeology Service) come in.
3.8.2 Risk
management
PPG16 sets out a number of stages in
‘archaeological risk management’.
Stage one - a desk-based study will assess
the likelihood and extent of any remains on the site based on the archaeological
and historical background of the site, the extent of disturbance caused by any
earlier construction work and the impact of the proposed scheme. This study
should be designed to provide the local authority with all the information it
needs to decide on the appropriate archaeological treatment of the site. The
study may suggest options in accordance with the client’s wishes but it is the
local authority that will have the last word. There are three likely outcomes
of this study:
- the local authority may approve the application with no further investigation;
- if the site is felt to have archaeological potential, the authority may require the applicant to submit a field evaluation report, which could involve digging test pits and trenches and other physical work on the site. This could be difficult or even impossible prior to planning permission if access to the land is restricted and it will certainly add to costs, with no guarantee that planning permission will be granted;
- permission may be granted subject to a planning condition or agreement to deal with the archaeological requirements.
Stage two - a field evaluation may be
required. This will usually be carried out in accordance with a brief set by
the local authority, along with the proposed research objectives and method
statements set out in the project design produced by the archaeological
contractor. The evaluation – whether required pre-or post-determination - will
then be submitted to the authority and they will either require further work or
the archaeological planning condition will have been discharged subject to
archiving of appropriate material and publishing results as specified.
Stage three - if further work is required,
the developer and the archaeologist should now get together to identify
measures to mitigate the impact of the proposed development on the archaeology.
This third stage can go two ways: either the local authority will specify that
archaeological deposits must be preserved in situ, without
being disturbed, or they will specify that they should be excavated and
recorded by professional archaeologists, normally under a planning condition.
This can involve a lot of expense in changing working methods on site in order
to preserve remains or in redesigning the foundations and other parts of the
works. Their proposals, once agreed with the authority and the curator, have to
be set out in detail in an archaeological project design that may then be
appended to the ensuing legal agreement between the archaeological contractor
and the developer.
It is worth pointing out that early
consultation between developers and archaeologists is beneficial. It may then
be possible to anticipate events. Money could be saved by combining the desk
assessment with the field study or by combining archaeological evaluation with
geotechnical investigation work. Money can also be saved by having
professionals with experience in smoothly integrating archaeological fieldwork
into complex construction programmes. Sometimes, for example, archaeological
excavation takes place within standing buildings before demolition.
Once the archaeological work has been
agreed, the use of a legal agreement has the effect of placing most of the risk
with the archaeologists carrying out the work within the agreed programme and
budget. However, the developer remains at risk if there is an unexpected
archaeological discovery on site that causes further delay or additional cost
or even a permanent loss of site value. It is against these possibilities that
insurance can be taken out. The insurance requirements may be considered under
the following headings. The most commonly purchased ones are delay and
redesign, followed by additional archaeological costs and cancellation.
3.8.4 Potential
cover requirements
1. Delay costs - additional costs incurred in
relation to the delayed completion of the development, which the insured is
legally liable to pay. This is likely to be the most significant unexpected
cost to the developer and would include additional interest payments.
2. Additional archaeological costs - incurred in undertaking a
scheme of archaeological work, including fieldwork, post-excavation work and
preparation of results to an agreed standard for publication, as required by
the planning authority or other statutory or curatorial organisation.
3. Cancellation costs - can be incurred as a result of
the necessary cancellation of all or part of a project because of revocation of
planning consent or the spot designation of unexpectedly discovered remains as
a scheduled ancient monument.
4. Redesign costs - the developer can incur this
cost as a result of a requirement to revise the layout or constructional
details of a project in order to ensure the preservation of unexpectedly
discovered archaeological remains.
5. Loss of profit - the nature of the ‘profit’ would vary
according to the insured’s business but would include loss of rent.
6. Loss of value - in extreme circumstances an
unexpected discovery might mean a loss of space or even a whole storey with the
result that the market value of the development is reduced. Before any
quotation for insurance can be given, an independent risk survey by the
underwriter’s archaeological consultant is required. The consultant’s fee,
which is usually between £500 and £2,000, has to be paid in advance and is
non-refundable. Underwriters’ minimum premium for this class of business is
£5,000.

3.8.5 Key
issues
Insurers do only cover the unexpected
so it is important to get cover in place after the basic work described above
but before someone starts digging foundation trenches. In the sequence of
stages set out above it makes most sense to deal with insurance requirements as
soon as possible in stage three. There can often be delays while the local
archaeological or planning authorities decide exactly what their requirements
are, but as soon as these are sorted out insurers should be in a position to
get things done quite quickly.
