Development-led and Commercial Archaeology: Key Concepts and Practices

Development-led archaeology

Archaeology carried out alongside construction and development projects

Commercial archaeology

Archaeology funded by developers as part of building projects

Cultural Resource Management (CRM)

Term for development-led archaeology used especially in North America

Rescue archaeology

Older term for quickly recording remains before destruction

Planning process (archaeology)

System where archaeology is built into development plans before construction

Polluter pays principle

Developers fund archaeology because they damage heritage

Mitigation archaeology

Recording and recovering data before a site is destroyed by development

Archaeological companies

Organisations (private, charity, or university-linked) hired to carry out excavations

Local planning authorities

Government bodies enforcing archaeological requirements in development

Planning condition

Requirement to complete archaeology before construction can proceed

Heritage protection

Laws preventing uncontrolled destruction of historic and archaeological sites

In situ preservation

Leaving archaeology undisturbed when possible

Exceptional preservation

Rare cases where important finds change or stop development

Nationally significant infrastructure

Major projects that can override normal heritage protections

Desk-based assessment

Research using maps, archives, and data to predict archaeological potential

Written Scheme of Investigation (WSI)

Plan outlining required archaeological work for a development

Tender process

Developers hire archaeological companies through competitive contracts

Archaeological workflow

Process from assessment to excavation, reporting, and planning approval

Archaeological knowledge output

Reports and findings produced from development-led work

Primary purpose of commercial archaeology

Enabling development rather than purely research

Evaluation trenches

Small test trenches to assess archaeological potential

Watching brief

Monitoring construction work to identify archaeology

Open-area excavation

Large-scale digging when significant remains are found

Sampling strategy

Excavating only part of a site due to time and cost limits

Shovel test pits

Small test holes used mainly in North America to locate sites

Geoarchaeology

Study of soils and environmental data in archaeological contexts

Standing building survey

Recording structures before alteration or demolition

Archaeological resource

Finite and non-renewable record of the past

Scheduled monument

Legally protected archaeological site

Listed building

Protected structure graded by historical importance

World Heritage Site

Internationally recognised site of outstanding cultural value

Heritage value (traditional)

Based on aesthetics, rarity, or monumentality

Social heritage value

Importance based on community or cultural meaning

Archaeological significance criteria

Judged by rarity, condition, and research potential

Scale of intervention

Only a small percentage of developments require excavation

Time pressure in archaeology

Work constrained by construction deadlines

Cost of archaeology

Small compared to overall development profits

Olympic Park excavation (London 2012)

Large-scale development-led project with extensive archaeology

Preservation bias

Only areas affected by construction are excavated

Archaeological loss

Much evidence destroyed despite mitigation

Finds examples

Artefacts such as tools, coins, structures, and environmental remains

Recent archaeology

Study of modern or industrial remains

Public benefit debate

Question of whether archaeology justifies destruction of heritage

Archaeology and development tension

Conflict between preservation and economic growth

Greenwashing in archaeology

Using archaeology to improve image of development projects

HS2 archaeology

Example of large infrastructure project using archaeology in public relations

Public archaeology value

Includes education, tourism, and community identity

Career in commercial archaeology

Entry-level work often as field archaeologist after degree

Field archaeologist (digger)

Role involving excavation and on-site recording

Specialist roles

Includes finds analysis, environmental studies, and reporting

Working conditions

Physically demanding, sometimes low-paid but improving

Career progression

Possible advancement to management or research roles

Fieldwork experience

Key requirement for employment in commercial archaeology
