# compute_reinforced_soil_wall Paid tier only. Calling this without an authenticated CivilQuants account returns TIER_INSUFFICIENT — sign up at https://civilquants.com/pricing or use the free-tier alternative compute_cantilever_wall. Reinforced soil retaining wall (RSW) using granular fill reinforced with horizontal layers of geogrid or steel tie strips, with one of four facing systems: precast concrete panels (Reinforced Earth™ / VSL Retained Earth style), segmental modular blocks (Allan Block / Keystone), wraparound soft face (vegetated or biodegradable mat), or Terramesh-style steel mesh face (re-using the S29 gabion vocabulary). The SECOND member of the earth_structures L1 leaf (after gabion_wall at S29), the SIXTH member of the wall family, the FIFTH structural system, and the FIRST wall family member with a face-area-primary measurement basis (m² of face + m² × layers of geogrid, both m²; every prior wall body was m³). 17th use of the classed-then-legacy attribute discrimination pattern. Routes via four new WorkCategory entries (RSW_FACING_PANEL, RSW_MODULAR_BLOCK, RSW_WRAPAROUND_FACE, RSW_TIE_STRIP) plus the GEOGRID category (whose handler is gap-filled in CESMM4/NRM2/MMHW this session) plus re-use of GABION_BASKET on the STEEL_MESH_FACE variant. Codes: CESMM4 E.8.4-8 (Class E Earthworks §E.8 stabilisation), NRM2 5.23-27 (Group 5 Excavating and filling), MMHW 600.15-19 (Series 600 Earthworks; SHW Cl. 624 reinforced earth retaining structures), and SMM7 D41.3/D41.4/D41.5/D20.21/D20.14.2 (D41 — Crib walls / gabions / REINFORCED EARTH — the NAMED home, now serving TWO wall families). Eight variant presets exercise all four RSWFacing values (2/2/2/2 split). Example params: wall_height=6 m (0.5–12), wall_length=40 m (5–200), depth_into_fill_m=4.5 m (0.35–15). Example call: {"params": {"wall_height": 6, "wall_length": 40, "depth_into_fill_m": 4.5}, "standard": "MMHW"}. Omitted parameters use sensible engineering defaults. Pass deliverables=["xlsx","dxf","pdf"] (any subset) to also receive one-shot download URLs in the same call: Excel BoQ (both tiers, watermarked free) plus the dimensioned DXF (CAD) and PDF drawing sheets (paid tier).

HTML page: https://policylayer.com/tools/com-civilquants-civilquants/compute-reinforced-soil-wall ## Facts - Tool: `compute_reinforced_soil_wall` - Server: Civilquants (`https://api.civilquants.com/mcp`) — https://policylayer.com/tools/com-civilquants-civilquants.md - Homepage: https://github.com/https://api.civilquants.com/mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server rate-limited: no - Parameters: 4 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `params` | object | yes | Parameter form for a reinforced soil wall. A single dataclass that — through combinations of its fields and the ``rsw_facing`` discriminator — produces all eig | | `standard` | string | no | | | `output_mode` | string | no | | | `deliverables` | object | no | | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "compute_reinforced_soil_wall", "arguments": { "params": {} } } } ``` ## Why compute_reinforced_soil_wall is rated High This tool executes a parametric estimating calculation based on specified inputs. While it does not create permanent data structures or delete records, it performs a non-trivial computation whose output depends on the arguments provided and could be used to generate cost estimates or engineering specifications that influence downstream decisions. From the tool's own definition: "Calling this tool performs a parametric computation (compute_reinforced_soil_wall) that generates Bills of Quantities for civil engineering assemblies." Risk signals: High parameter count (41 properties) · Bulk/mass operation — affects multiple targets ## Use case AI agents invoke compute_reinforced_soil_wall to trigger actions in Civilquants. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
