Project-specific Professional Indemnity insurance. ISO 9001:2015.
Where this delivery model earns its premium.
Retaining walls 1-8 m
Stability analysis per BS 8002 + BS EN 1997 + USACE EM 1110-2-2502. Base width 0.5-0.7H for self-stable design. Galvanised, Galfan, or PVC-coated mesh per BS EN 10223-3/10244-2. Stepped or vertical face per consultant aesthetic spec.
Riverbank training
USACE EM 1110-2-1601 + JPS Drainage Manual hydraulic design. Gabion mattress on bank face, gabion box at toe. Permissible velocity 4-6 m/s, shear stress 200-400 N/m squared. Edge anchorage at upstream/downstream extents prevents flanking failure during peak flow.
Bridge-pier scour protection
FHWA-HEC-23 + AASHTO LRFD design. Gabion mattress around bridge piers in the scour zone. Horseshoe vortex factor for protection extent. 100-year ARI flood design typical for federal road bridges.
Drainage chute armoring
USACE EM 1110-2-1601 for high-velocity discharge channels. Gabion mattress or thin box in concrete-lined or earth chutes from cut slopes, highway drainage, storm pond outlets. Energy dissipation plus erosion resistance.
Highway cut-slope toe
Gabion box toe wall at base of cut slope. Permeable toe drain plus load-bearing. Pairs with horizontal drains emerging through gabion face and with soil nailing above the wall for full slope stabilisation.
Architectural feature walls
Welded mesh or PVC-coated woven gabion for high-visibility landscape walls (commercial, hotel, residential premium). Hand-packed face stones for aesthetic finish. Vegetated-face option via hydroseeding or pocket planting.

What lands on the consultant's desk for review.
- Design report: assumptions register, geotechnical or hydraulic parameters, design codes applied, factor of safety check results (overturning, sliding, bearing, global), sensitivity check.
- Calculation backup: software output (Slope/W, Plaxis, or USACE/JPS hydraulic spreadsheets) with input data and result extraction.
- Drawings: plan, sections, details, foundation profile, anchorage detail (for hydraulic applications), mesh-and-stone schedule.
- Material schedule: mesh type (woven hexagonal vs welded), coating class (galvanised vs Galfan vs PVC-coated), stone gradation and quality requirement (igneous rock, density above 2.4 t/m cubed, water absorption below 5 percent), lacing wire.
- Construction sequence and method statement: foundation preparation, basket assembly, placing and tying, internal bracing, stone fill (hand-pack face stones, machine-tip interior), lid closure, course-by-course construction.
- QA programme: stone source certificate, mesh manufacturer certificate of conformance, lacing wire batch record, dry density verification per BS EN 10223-3.
- Monitoring proposal (where required): settlement plate, optical survey monuments for tall walls.
- Risk register: identified risks with mitigation and residual risk allocation.
Who carries what.
| Risk type | Typical owner |
|---|---|
| Mesh manufacturing defect | Contractor (passes to mesh manufacturer) |
| Stone quality non-conformance | Contractor (verified at stone source) |
| Installation defect (workmanship) | Contractor |
| Design error | Contractor (covered by PI insurance) |
| Ground condition variation from baseline | Typically shared per contract risk register, rate provisions for additional foundation works |
| Hydraulic variation (river flow / scour) from design assumptions | Typically shared, monitoring + adaptive works provisions |
| Programme delay due to weather | Typically shared with extension-of-time provisions |
| Post-construction performance shortfall within design life | Contractor within defects liability period (typical 24 months) |
Standard insurance: Professional Indemnity (PI) for design negligence exposure, Contractor's All Risk (CAR), workmen's compensation, public liability.
Lump sum or design fee plus measured.
Lump sum (LSTK)
Single project price covering design + supply + installation + QA + handover. Most common for residential and commercial projects with well-defined scope (wall geometry, ground conditions, design life). Risk allocation per contract risk register. Buyer pays a known price; contractor manages variability within the risk envelope.
Design fee + measured construction
Design fee as fixed lump sum or percentage of construction value (typical 3-8 percent depending on complexity). Construction priced by measured quantity at agreed unit rates: per m cubed of gabion wall volume, per m squared of mattress area, per linear metre of anchorage. Most common for federal works (JKR, LLM, JPS) where scope may vary against initial ground or hydraulic assumptions.
Three checks that signal yes.
- Engineering is non-trivial. Settlement-prone foundations, dynamic river channels, complex hydraulic interaction with adjacent structures, bridge-pier scour. Single-point design responsibility prevents design-installation interface issues that can become expensive failures.
- Buyer wants single accountability. Property developers, residential builders, private clients without in-house geotechnical or hydraulic engineering teams benefit most. Buyer states functional requirement, contractor delivers working system.
- Project programme is tight. Design and build collapses the design-tender-build cycle, saving 2-6 months on typical projects. Useful for emergency works (post-flood riverbank repair) and tight federal-corridor delivery windows.
For straightforward gabion retaining walls 1-3 m on stable residual soil foundations, install-only (per consultant design) may be more cost-effective. Send geometry + ground report to engineering desk for honest recommendation.
Buyers and consultants usually ask:
How do you handle peer review of your design? +
Can we do design and build on a JPS river-corridor project? +
What's the design programme typically? +
Do you use independent design software? +
What if our project consultant disagrees with your design? +
