Where this delivery model earns its premium.
MSE wall 4 to 20 m height
StrataGrid PET 50 to 200 kN/m, internal + external + serviceability + connection stability per BS 8006-1 and FHWA-NHI-10-024. Modular block, gabion, or precast panel facing. See MSE wall and MSE wall design with geogrid.
Reinforced soil slope (RSS)
Slope angles 30 to 70 degrees with StrataGrid PET reinforcement layers. Slip-circle factor of safety analysis. Vegetated face or geocell facing. See RSS.
Basal reinforcement over peat or soft clay
StrataGrid or composite at embankment base. Rowe-Soderman 1985 for very soft ground or slip-circle plus tensile per BS 8006 Annex A. Pairs with PVD for accelerated consolidation. See basal reinforcement and PVD.
Segmental retaining wall (SRW)
Modular block facing with StrataGrid PET. Connection capacity per NCMA SRW Design Manual. Heights up to 8 m typical with proven connection systems.
Bridge abutment with reinforced soil
Gabion-faced or modular block facing, StrataGrid 100 to 200 kN/m typical. AASHTO LRFD design alignment with bridge structure. See bridge abutment.
Working platform over weak subgrade
Biaxial PP geogrid plus crushed aggregate platform for crane and tracked-rig operations on soft ground (CBR 1 to 3). Design per AASHTO + Giroud-Han 2004 method.

What lands on the consultant's desk for review.
- Design report: assumptions register, geotechnical parameters, design codes applied, factor of safety check results, reduction factor framework with manufacturer datasheet cross-reference, sensitivity check on key variables.
- Calculation backup: software output (MSEW, Wall Calc, Slope/W, ReSlope, Plaxis, or equivalent) with input data and result extraction. Hand-check verification on critical load cases.
- Drawings: plan, sections, details, reinforcement schedule with layer positions, lengths, tensile grades, and orientation.
- Material schedule: SKU-by-SKU material quantity (StrataGrid grades per layer), manufacturer spec sheet reference, design strength T_d after reduction factors.
- Construction sequence and method statement: lift-by-lift fill placement, compaction control, reinforcement placement, facing erection (for MSE wall), settlement monitoring.
- QA programme: roll receipt, batch sampling, layer audit, pullout test programme per ASTM D6706 on production samples, connection capacity verification (for SRW).
- Monitoring proposal (where required): inclinometer behind wall face, vibrating-wire strain gauge on geogrid layer, settlement plate, optical survey monuments on wall face.
- Risk register: identified design and construction risks with mitigation and residual risk owner allocation.
Who carries what.
| Risk type | Typical owner |
|---|---|
| Material defect (mill manufacturing fault) | Contractor (passes to manufacturer via Starwall route) |
| Installation defect (workmanship) | Contractor |
| Design error (calculation or specification fault) | Contractor (covered by Professional Indemnity insurance) |
| Ground condition variation from baseline | Typically shared per contract risk register, with rate provisions for additional treatment |
| Programme delay due to weather | Typically shared with extension-of-time provisions |
| Programme delay due to client-direction change | Buyer |
| Post-construction face deformation within design tolerance | No claim (within design) |
| Post-construction performance shortfall within design life | Contractor within warranty period (typical 24 months defects liability, longer for specific applications) |
Standard insurance package: 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. Buyer pays a known price; contractor manages variability within the contract risk envelope.
Design fee + measured construction
Design fee paid as fixed lump sum or percentage of construction value (typical 3 to 8 percent). Construction priced by measured quantity at agreed unit rates. Most common for federal works where scope is subject to variation. Buyer pays for design certainty, construction quantity flexes against site conditions.
Three checks that signal yes.
- The geogrid is structurally critical. If the geogrid is just a road-base separator under low-volume traffic, design and build is overkill. If the geogrid is structural (MSE wall reinforcement, RSS, basal mat over soft ground, bridge abutment), single-point design responsibility prevents design-installation interface issues that can become expensive failures.
- The buyer wants single accountability. Property developers, residential builders, and private clients without an in-house geotechnical engineering team benefit most from design and build. Buyer states functional requirement, contractor delivers working system.
- The site conditions are challenging. Soft ground, peat, MSE wall on settlement-prone foundation, RSS in complex topography, bridge abutment over weak subgrade. Integrated design-installation thinking outperforms siloed design-bid-build on these conditions.

Can we do design and build on a federal works contract? +
What's the design programme typically? +
Do you use independent design software? +
What if our project consultant disagrees with your design? +
What's the typical post-construction performance check? +
