Excavation Support
Excavation Support Design
Safe, buildable excavation support — from battered slopes to sheeted and framed solutions — designed around your ground, your plant and your programme.
Generated atmospheric imagery. Illustrative temporary works families, not identified projects.
What this covers
Excavations fail fast and without warning. We design excavation support that fits what you actually have — ground, groundwater, surcharges, adjacent structures and available kit — from battered profiles through proprietary boxes and sheets to framed solutions, with reference to BS 5975:2024 and CIRIA good practice.
- Battered excavation profiles and benching
- Trench boxes, drag boxes and proprietary shields
- Sheeted and framed excavation support
- Groundwater, surcharge and adjacent-structure assessment
- Excavation and installation sequence design
- Interfaces with piling mats, cranes and haul roads
How we word it
- Designs rely on ground and groundwater information supplied — unverified assumptions are stated and flagged for confirmation.
- Daily inspection and permit control remain site responsibilities.
- Subject to competent checking under the project temporary works procedure.
Typical deliverables
- Support design calculations and drawings/sketches
- Installation, use and removal sequence
- Design risk assessment with residual risks
- Inspection and permit-to-dig/enter interface notes
Information we need for an accurate quote
Partial information is fine to start — we will tell you what matters most.
- Depth, plan size and shape of the excavation
- Ground type and any GI / trial pit information
- Groundwater expectations or observations
- Surcharge loads — plant, spoil, traffic, structures nearby
- Buried services information
- Preferred method or available support kit
Typical hold points & interfaces
- Support installed and inspected before entry
- Re-inspection after rain, surcharge change or partial removal
- Permit-to-dig / permit-to-enter interfaces at each stage
When contractors use this
- A dig goes deeper than a batter can safely go
- Ground, water or surcharge conditions have changed
- Working next to structures, roads or live services
- A proprietary system needs project-specific justification
