Archaeological Investigations in a Modern World

At Arthian, we deliver tailored archaeological investigations that support planning compliance, satisfy legal conditions and protect the historic environment. Working across England, Scotland, and Wales, our fieldwork services help clients meet archaeological requirements efficiently and proportionately, without compromising quality or timelines.
Our team liaises directly with local authorities, contractors and sub-consultants to secure practical, cost-effective solutions that align with planning conditions. We advise on methods, budgets and delivery schedules, ensuring each investigation is scoped realistically and competitively.
We prepare Archaeology Written Schemes of Investigation (WSIs) based on agreed project terms for submission to the planning authority and manage delivery from supervision to archiving.

Field Investigation Methods

We offer a full suite of archaeological fieldwork techniques, adapted to project scale, site sensitivity and planning requirements.

During works, our consultants supervise field teams and attend monitoring visits from planning authorities. On completion, we provide planning-compliant reporting for discharge of conditions or legal consents, and arrange for archiving of project material in accordance with national standards.

Our Archaeological Capabilities

Our capabilities include:

Preliminary Site Investigation Monitoring

Watching briefs

Archaeological evaluation (e.g. trial trenching)

Preliminary Site Investigation Monitoring

We provide early-stage archaeological monitoring to identify heritage constraints and inform planning decisions before groundworks begin, helping developers manage risk and engage proactively with authorities. Our approach includes:

Early-stage site walkovers and desk-based reviews: Identifying known heritage assets and assessing potential for undiscovered archaeology.
Monitoring of geotechnical and ground investigation works: Observing trial pits, boreholes, and other early groundworks to detect archaeological features.
Targeted field surveys: Using non-intrusive techniques such as geophysical surveys to assess subsurface potential.
Stakeholder coordination: Liaising with local planning authorities, Historic Environment Records, and archaeological advisors to align investigations with planning requirements.
Risk-based reporting: Providing clear, concise outputs to support planning applications and inform mitigation strategies.

Watching briefs

Our archaeologists conduct watching briefs during construction to identify and record unexpected finds, ensuring heritage assets are protected and planning conditions are met. Our service includes:

On-site archaeological monitoring: Attending groundworks to observe and assess any archaeological features revealed during excavation.
Real-time recording and interpretation: Documenting finds and features using industry-standard methods and formats.
Rapid response to discoveries: Advising on appropriate action if significant remains are uncovered, including temporary work stoppages or mitigation.
Liaison with planning authorities and heritage bodies: Ensuring transparent communication and alignment with regulatory requirements.
Final reporting and archiving: Producing clear records for submission to local Historic Environment Records and planning authorities.

Archaeological evaluation (e.g. trial trenching)

We conduct trial trenching to assess archaeological deposits, supporting informed planning and mitigation by revealing below-ground heritage assets and regulatory considerations. Our service includes:

Targeted trenching across the site: Excavating sample areas to assess archaeological potential based on desk-based and geophysical findings.
Evaluation of deposit significance: Identifying and interpreting features, artefacts, and stratigraphy to determine heritage value.
Support for mitigation planning: Informing decisions on preservation in situ, excavation, or redesign to avoid sensitive areas.
Compliance with planning conditions: Aligning investigations with local authority and national heritage guidance.
Clear reporting and recommendations: Delivering concise, evidence-based outputs to support planning submissions and heritage management.

Frequently Asked Questions

What is a Written Scheme of Investigation (WSI)?

A WSI is a formal method statement outlining how archaeological work will be conducted, submitted to the planning authority as part of fulfilling conditions or legal consent.

Do I need a watching brief or full excavation?

This depends on site potential, planning conditions, and risk factors. Our consultants help determine the most appropriate and proportionate method.

Can you help manage investigation costs?

Yes—our team negotiates fieldwork scope, timelines and methodology with stakeholders to ensure competitive pricing and avoid unnecessary delays.

What happens after fieldwork is complete?

We deliver reports for discharge of conditions and archive records to regional repositories. We also coordinate with local authorities for sign-off and planning release.
