calculate_technical_spec Read-only

[PRO] Performs numerical technical calculations for construction trades with code-compliant results. Use this tool when a specific measurement, size, rating, or capacity needs to be calculated — not just checked for compliance. Returns the calculated value with units, the method or formula used, relevant derating or correction factors, and the code reference that governs the calculation. Supports: cable/conductor sizing (mm2 or AWG), voltage drop (%), pipe sizing (mm or inches), HVAC duct sizing (CFM/L/s), heat load calculations, load current calculations, and more. Example inputs: 'Cable size for 32A circuit, 25m run, 240V single phase, clipped direct', 'Pipe size for 40 fixture units copper hot water supply', 'Duct size for 1200 CFM round duct'.

tradestring, required

The trade for this calculation. Determines the applicable standard and units.

regionstring, required

Use the state, province or country where the user works; if they have not said, ask them - never assume NSW or Australia. Jurisdiction. Affects which standard and units apply (e.g. mm2 for AU/UK, AWG for USA).

calculationstring, required

Describe the calculation needed with all relevant parameters. Include: load/flow value, distance/length, voltage/pressure, installation method, ambient conditions. Example: 'Cable size for 45A, 30m run, 240V, single phase, in conduit, 35 degrees ambient'.

rolestring

User role. Affects detail level of the output.

api_keystring

check_compliance

Answers construction trade compliance questions with exact code references and clause citations. Use this tool when a tradesperson or engineer asks whether a specific installation, practice, or configuration is compliant with local regulations. Returns a COMPLIANT, NON_COMPLIANT, or REQUIRES_VERIFICATION status with the precise standard (e.g. AS/NZS 3000:2018 Clause 3.2.4) and any critical caveats. Covers electrical, plumbing, HVAC, welding, carpentry, roofing, gas fitting, solar, fire protection, and concrete trades across Australia, UK, USA, Canada, and EU. Do NOT use this tool for numerical calculations (use calculate_technical_spec instead) or for generating safety checklists or RAMS documents.

generate_rams

[PRO] Generates a complete Risk Assessment and Method Statement (RAMS) document — called a Job Hazard Analysis (JHA) in the USA or Safe Work Method Statement (SWMS) in Australia. Use this tool when a foreman or PM needs a formal safety document before a high-risk task. Output includes: Section 1 — Hazard Register (tabular, with severity/likelihood/risk rating/controls/regulations), Section 2 — Method Statement (numbered sequential steps), Section 3 — Required Qualifications and Certifications. The document is formatted for printing or inclusion in a site safety file. This tool produces a longer output than other tools — expect 800-1500 words. Example tasks: 'Electrical switchboard installation in commercial building NSW', 'Gas line installation in residential kitchen UK', 'Roof framing timber frame residential NSW'.

read-only

Argument	Type	Description
role	string	Role of the person generating the RAMS. Foreman or PM recommended.
task*	string	Full description of the task requiring the RAMS. Include: what work, where, at what height or voltage, any confined space, any hot work. The more detail, the more accurate the hazard register.
trade*	string	The trade performing the work.
region*	string	Use the state, province or country where the user works; if they have not said, ask them - never assume NSW or Australia. Jurisdiction. Determines applicable WHS/CDM/OSHA legislation cited in the document.

generate_safety_checklist

[PRO] Generates a numbered safety checklist for a specific construction task with PPE requirements, hazard controls, and regulatory citations for each item. Use this tool when a foreman or safety officer needs a task-specific checklist before work begins. Each checklist item includes: the safety requirement, the specific control measure, and the regulation or standard that mandates it (e.g. WHS Act 2011, CDM 2015, OSHA 29 CFR 1926). Do NOT use this tool to generate a full RAMS document — use generate_rams for that. Example tasks: 'working at height on a residential roof', 'hot work near fuel lines', 'isolating and working on a 415V switchboard'.

read-only

Argument	Type	Description
role	string	Role of the person who will use the checklist.
task*	string	Specific task description. Be precise about the activity, location, and any known hazards. Example: 'Installing 415V switchboard in an occupied commercial building, working at 3m height'.

Returns the standard name, edition year, specific clause or table, and a plain-English summary of what that clause requires. Useful for pre-populating compliance documents, RAMS, or certificates. Examples: 'AS/NZS 3008 cable sizing tables', 'CDM 2015 notification thresholds', 'NEC Article 210 branch circuits'.

get_inspection_requirements

[PRO] Returns all mandatory inspection hold points, sign-off authorities, certificates to be issued, and notification requirements for a construction installation in a specific jurisdiction.

Prevents costly rework caused by covering work before mandatory inspection. Returns a numbered list of inspection stages with: inspector role/authority, certificate type and form number, regulatory reference, and notification timing. Example installations: 'residential electrical installation NSW', 'timber frame residential build NSW', 'gas fitting domestic kitchen UK'.

read-only

Argument	Type	Description
role	string	Role of the person requesting the inspection requirements.
trade*	string	The trade performing the installation.
region*	string	Use the state, province or country where the user works; if they have not said, ask them - never assume NSW or Australia. Jurisdiction. Inspection authorities and certificate types vary significantly by region.

Use this tool before calling other tools to confirm that the target region is supported, or to discover available regions when the user has not specified one. Returns a structured list of countries and their sub-regions (states, provinces, nations) along with the primary standards that apply in each region.

read-only

Argument	Type	Description
trade*	string	The trade for which to list supported regions.
api_key	string	Legis-Link API key. Optional: leave empty for the free tier (50 requests/day); Pro users paste their ll_p_ key.

Returns COMPLIANT, NON_COMPLIANT, or REQUIRES_VERIFICATION with the specific clause that governs the material selection, and — if non-compliant — the compliant alternative. Use this tool BEFORE ordering materials to avoid costly substitutions on site. Do NOT use this tool for general compliance questions — use check_compliance instead. Example inputs: '2.5mm2 TPS cable for 20A underground direct burial circuit NSW', 'Class 12 copper pipe for domestic hot water NSW', 'R3.5 glasswool batts for external wall cavity UK Building Regs'.
