At CGL, our experienced team understands that the preliminary screening of a site is often a key influence in the decision-making process.

Our Site Feasibility and Planning Constraints Services 

CGL is extremely experienced in site feasibility and planning constraints services - including phase 1 desk study services, producing clear client guidance for proposed developments, based on:

  • Environmental And Geological Constraints,
  • Local Policy And Planning Guidance,
  • Cost Implications Of Remediation,
  • Advice On The Feasibility Of The Project Program
  • Budgets Based On Findings

Alongside desk-based works, CGL can undertake and commission preliminary non-intrusive works such as geophysics-based surveys, and Non-Destructive Testing (NDT) on existing foundations and similar structures to further direct the scope of future works.

Phase 1 Desk Study Processes

Typically, the process commences with a detailed phase 1 desk study which is tailored to meet the requirements of each client either as individual reports submitted as part of the planning process or as part of the intrusive investigation documentation.

Our phase 1 desk study services form an essential part of the investigation process for all sites whether brownfield or greenfield, and whether geo-environmentally or geotechnically biased.

CGL has long championed the cost-effectiveness of holistic site investigations that encompass both substructure design and contamination mitigation. All phase 1 desk study investigations will require Conceptual Site Models (CSM) for contamination risk and need to consider past land use, geology (both published and unpublished), and environmental incidents in context and with a view to eventual construction. 

We also consider other factors such as existing structures and nearby buried assets/infrastructure, historical land-working (including mining), and outside influences such as Unexploded Ordnance (UXO).

Experienced Industry Leaders

CGL does not simply provide a web-based generic collection of data without project context but incorporates the requirements of industry-based standards from the Association of Geotechnical and Geoenvironmental Specialists (AGS) as well as BS 5930 and BS 10175.

Typically, our phase 1 desk study investigations can be assembled in a short timeframe by our experienced geotechnical and geoenvironmental engineers and are quality audited by our highly experienced team.

Our investigations have the potential not only to save clients considerable amounts of money and time in both the planning and construction process, but also work to refine and target future intrusive investigations.
