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. Catalogue-driven utility access chamber covering ten standard UK types: BT/Openreach jointing chambers JC1-JC4 (defaulting to UTILITY_PROVIDER_SUPPLY routing), water meter chamber (FW6), wastewater inspection chamber (RW9), valve chamber, gas Emergency Control Valve pit (ECV), LV electrical link box, and cable draw pit. Composite emission: precast chamber unit + BS EN 124 cover & frame (PC supply) + excavation + bedding (SHW Cl. 803) + granular surround + optional geotextile + selected fill + disposal. Routes via manhole_type=utility_chamber attribute discrimination through CESMM4 Class K.1.5.x, NRM2 33.7.11-.13, MMHW 500.5.13-.15 (SHW Cl. 507), and SMM7 R12.3.10-.12. JC types route their chamber unit through the v18 statutory-undertaker supply route infrastructure (CESMM4 Class A.4.3, NRM2 Group 1, MMHW Series 100, SMM7 A53) as a PC sum plus contractor attendance line. Example params: bedding_thickness_mm=150 mm (75–300), bedding_overhang_m=0.1 m (0.075–0.3), surround_thickness_m=0.15 m (0.1–0.3). Example call: {"params": {"bedding_thickness_mm": 150, "bedding_overhang_m": 0.1, "surround_thickness_m": 0.15}, "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).
