CivilQuants computes audit-traceable Bills of Quantities for civil-engineering assemblies — culverts, manholes, retaining walls, pavements, drainage, earthworks — across four UK measurement standards (CESMM4, NRM2, SMM7, MMHW). Parametric inputs in; a methodology-structured BoQ with every quantity traceable to its formula out, exportable to Excel, DXF and PDF. Paid subscribers also get 10 senior-QS methodology prompts (tender review, risk assessment, measurement and contract advice, geotechnical interpretation and more). Six assemblies are free and anonymous.

| compute_connection_to_existing | 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_manhole. Enumerated extra-over connection of a new drainage carrier pipe into an existing asset: existing manhole / inspection chamber, existing sewer or drain (via saddle / wye / cut-in junction), or existing outfall / watercourse / surface system. Routes via CESMM4 I.7.1/2/3 (Class I §I.7 Pipework Ancillaries — Connections), NRM2 33.6.1/2/3, MMHW 500.5.1/2/3 (SHW Cl. 506 Connections to existing sewers, drains and service runs), SMM7 R12.4.1/2/3, with a bore-size digit suffix appended in all four. The connection_type attribute is the discriminator that routes to the right sub-code; the bore digit refines within. Six variant presets cover all three connection types × two characteristic bores. Unit: Nr. Opens the new `drainage_ancillaries` L2 leaf (reserved for ditch, hard-material extra-over, CCTV testing, etc. in future sessions). Sibling assembly: carrier_pipe_run — the S32 pair that delivers a complete tender drainage line. Example params: diameter_mm=225 mm (100–2400). Example call: {"params": {"diameter_mm": 225}, "standard": "MMHW"}. Omitted parameters use sensible engineering defaults.

| compute_hard_material_in_trench | 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_manhole. Linear extra-over measurement of hard material encountered during drainage trench excavation. Discriminates between natural rock (CESMM4 E.6 / NRM2 5.6.1 / MMHW 500.6.1 / SMM7 R12.6.1) and artificial hard material — buried concrete / masonry / obstructions (CESMM4 E.7 / NRM2 5.6.2 / MMHW 500.6.2 / SMM7 R12.6.2). The platform's first dual-quantity WorkItem: carries both length_m and volume_m3 so CESMM4/NRM2 (m³) and MMHW/SMM7 (m) each render with their correct unit per the standards' rules. Eight variant presets cover both hard-material types × four depth bands. SMM7 R12 deems trench excavation (including hard material) included in the pipe-run rate — the SMM7 handler emits a zero-priceable annotated line for tender transparency (third use of the deemed-included extra-over annotation pattern). Closes the drainage_ancillaries L2 leaf at 4/4 members. Sibling assemblies: connection_to_existing (S32), ditch (S33), pipework_testing (S33). Example params: length_m=10 m (0.5–500), max_depth_m=1.5 m (0.3–10), trench_width_m=0.7 m (0.3–3). Example call: {"params": {"length_m": 10, "max_depth_m": 1.5, "trench_width_m": 0.7}, "standard": "MMHW"}. Omitted parameters use sensible engineering defaults.

| compute_ditch | 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_manhole. Linear primary measurement of an open earthwork drainage channel — trapezoidal cross-section, four lining variants (unlined / geotextile / granular / concrete). Routes via CESMM4 Class E.4 (excavation for cuttings), NRM2 Group 34.10 (site works: open drains and ditches), MMHW Series 500.4 (SHW Cl. 514 Earthwork ditches and drains), SMM7 R13.4 (Land Drainage — ditches). Eight variant presets cover all four lining types x two characteristic size scenarios each. Unit: M. Second member of the drainage_ancillaries L2 leaf (opened at S32 with connection_to_existing). 20th use of the classed-then-legacy attribute discrimination pattern via the lining_type discriminator. The four standards genuinely diverge on which work-section heading owns ditches (Class E vs Group 34 vs Series 500 vs R13) — the platform renders all four honestly from one source WorkItem. Example params: run_length_m=100 m (1–1000), top_width_mm=1700 mm (200–10000), bottom_width_mm=500 mm (100–5000).

Introduces the platform's third named maturity pattern: deemed-included extra-over annotation (joining classed-then-legacy and declared-then-banded). Eight variant presets cover all four test methods x two bore scenarios each. Unit: M. Third member of the drainage_ancillaries L2 leaf. 21st use of the discriminator pattern via test_method. Example params: length_tested_m=100 m (1–2000), diameter_mm=225 mm (100–2400). Example call: {"params": {"length_tested_m": 100, "diameter_mm": 225}, "standard": "MMHW"}.

Example call: {"params": {"stem_height": 4, "stem_thickness_top": 0.3, "stem_thickness_bottom": 0.45}, "standard": "MMHW"}. Omitted parameters use sensible engineering defaults. Pass deliverables=["xlsx"] to also receive a one-shot Excel BoQ download URL in the same call. Pass `freeboard` (clearance below the wall top, m) instead of the retained-height field to set the retained fill by clearance — the engine back-calculates it as stem − freeboard. Supplying both is rejected. |
| compute_counterfort_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.

In-situ mass concrete gravity retaining wall (typical C20/25 to C25/30) with trapezoidal cross-section, retaining soil by self-weight rather than structural action. Eight variant presets exercise the parameter form — landscape, highway boundary, trapezoidal, stepped-front, toe-projection, keyed-base, stepped-foundation, and battered-back-vertical-front. Routes via wall_type='gravity' attribute discrimination through CESMM4 F.5.3, NRM2 11.2.3, MMHW 1700.5 (SHW Cl. 1704 structural concrete), and SMM7 E10.2.3. Reinforcement default zero (gravity walls are nominally unreinforced); optional nominal face mesh available via nominal_face_reinforcement_kg_per_m3 parameter. Includes excavation (battered or supported, level or stepped foundation), blinding, drainage system (subsoil drain + granular surround + geotextile separator), Class 6N backfill, disposal, and formwork to vertical and battered faces. 13th use of the classed-then-legacy attribute discrimination pattern, and first use in the retaining wall family — opening the wall moat for subsequent counterfort (S30), anchored (S31) and bored pile (S32) variants. Example params: stem_height=3 m (1.5–6), stem_thickness_top=0.4 m (0.2–1), stem_thickness_bottom=1.3 m (0.4–2.5).

| render_skill_report | Render previously-computed BoQ results into a deliverable (Excel workbook or Word report). Excel is free with watermark + sheet protection; Word is paid-tier only and returns a TIER_INSUFFICIENT envelope for anonymous callers. The wire shape matches POST /api/v1/mcp/render exactly. |
| save_project | Persist a CivilQuants project with its assembly list. Paid tier only — anonymous callers receive a TIER_INSUFFICIENT envelope pointing at https://civilquants.com/pricing. |
| get_project | Fetch a previously saved CivilQuants project by id. Paid tier only — anonymous callers receive a TIER_INSUFFICIENT envelope. |
| recompute_project | Re-run every enabled assembly in a saved project and render aggregated BoQs across the requested measurement standards. Paid tier only — anonymous callers receive a TIER_INSUFFICIENT envelope. |
| compute_multi_section_assembly | Compute one sectioned/linear assembly across multiple sections in a single call and return a combined Bill of Quantities plus per-section results. Each section sets its own run_length and geometry; shared_params apply to all sections. Use for a wall, kerb run, drain or barrier that changes along its length. assembly_slug must be a sectioned assembly (e.g. cantilever_wall, kerb_run, edge_drain); non-linear items return INVALID_INPUT. Free tier: MMHW only, each section consumes one daily slot. Example: {"assembly_slug":"cantilever_wall","standard":"MMHW","sections":[{"label":"Bay 1","run_length":20,"stem_height":1.5},{"label":"Bay 2","run_length":15,"stem_height":2.4}]}. |
| resolve_assembly_from_description | Resolve a plain-English job description to candidate catalogue assemblies and the fields you'll need to compute one. Deterministic router — it does NOT return a Bill of Quantities and NEVER guesses parameter values; it returns candidate slugs (plural when ambiguous, with clarifying questions), each assembly's tier, whether it supports compute_multi_section_assembly, and per-field metadata (unit, min/max, default). Then call compute_<slug> (or compute_multi_section_assembly) with the values you fill in. Also known as compute_from_description. Example: {"description":"a 3 m deep manhole","preferred_standard":"MMHW"}. |
