Generate the complete paper package that contractors need to build a system — Bill of Materials, installation sequences, commissioning tests, and Operations & Maintenance manuals — from verified engineering designs.
Activation: After the Architect, Calculator, and Safety agents complete a design and the blueprint engine has generated drawings. InfrastructureRequest with outputFormat including 'construction'.
Four output types:
Bill of Materials (BOM): Structured material list with quantities, part numbers, and suppliers extracted from verified design calculations.
Installation Sequence: Code-driven ordering of construction activities with trade assignments, prerequisites, and inspection hold points.
Commissioning Checklists: Pre-commissioning test procedures (hydrostatic, megger) and system startup procedures with acceptance criteria.
O&M Manual: Maintenance schedules, spare parts lists, operating procedures, and emergency procedures for the completed system.
When to use: Design is verified and safety-reviewed, ready for construction. All calculations must pass Safety Warden review before generating construction documents.
Key constraint: All construction documents require review by a licensed Professional Engineer before use in procurement, construction, or installation.
ENGINEERING DISCLAIMER: All construction documents generated by this skill are AI-assisted drafts. They MUST be reviewed, stamped, and signed by a licensed Professional Engineer (PE) before use in procurement, construction, installation, or commissioning. Local building codes, jurisdictional requirements, and site-specific conditions may impose additional requirements not captured here. User assumes all responsibility for PE review and code compliance.
Quick start: Provide a completed BlueprintPackage (from the blueprint engine) and this skill generates all four document types. Templates are available in @references/templates/ for customization.
The BOM is derived from verified design calculations and drawings. Each CalculationRecord in the BlueprintPackage identifies materials by their engineering specifications; the BOM skill translates these into procurement-ready line items.
Extraction process:
Parse P&ID drawings for pipe sizes, fittings, valves, and equipment tags
Parse SLD drawings for conductors, conduit, panelboards, and protective devices
Cross-reference with CalculationRecord outputs for exact sizing (pipe NPS, conductor AWG, equipment ratings)
Apply material specifications from design basis (ASTM pipe grades, NEC conductor types, equipment model numbers)
Add supports, hangers, and insulation per ASME B31.9 (pipe) and NEC 300 (conduit) spacing requirements
Include consumables (welding rod, solder, tape, sealant, fasteners)

The hydrostatic test verifies piping system integrity before insulation and concealment.
Test parameters per IPC 312.5:
Parameter
Requirement
Test pressure
1.5x maximum working pressure, minimum 100 PSI, maximum 500 PSI
Hold time
15 minutes minimum
Acceptance criteria
No pressure loss greater than 5 PSI during hold period
Medium
Clean water (potable for domestic systems)
Temperature
Ambient (not below 40 deg F to prevent freezing)
Test equipment requirements:
Calibrated pressure gauge: 2" face minimum, 1% accuracy class
Gauge range: test pressure at 50-75% of gauge full scale
Hand pump or hydrostatic test pump
Isolation valves (ball or gate, not butterfly)
Temporary test caps or blind flanges
Procedure:
Isolate system from permanent equipment (remove pressure relief valves, install temporary caps)
Fill system with clean water, vent all air from high points
Pressurize slowly to test pressure
Record initial pressure and time
Hold for 15 minutes; record pressure at 5-minute intervals
Pass: pressure drop less than or equal to 5 PSI over 15 minutes
Fail: locate and repair leaks, repeat test from step 2
Common failure causes: Threaded joint not properly sealed, flange gasket improperly seated, valve packing not tightened, temporary cap cross-threaded.
Megger Test — Insulation Resistance (IEEE 43)
The megger test verifies conductor insulation integrity before energization.

Systems 1001-5000V
Test voltage
500 VDC
1000 VDC
Minimum acceptable IR
1 MOhm (absolute minimum)
1 MOhm (absolute minimum)
Practical minimum (new)
100 MOhm
100 MOhm
Duration
1 minute (standard reading)
1 minute + optional 10-minute PI test
Polarization Index (PI)
PI = IR_10min / IR_1min, target > 2.0
PI > 2.0 required
Test setup:
All conductors tested phase-to-phase and phase-to-ground
Far end of each conductor disconnected (open circuit)
All sensitive electronics (VFDs, UPS control boards) disconnected before testing
Ambient conditions recorded (temperature and humidity affect IR readings)
Polarization Index interpretation:
PI Value
Insulation Condition
< 1.0
Dangerous — do not energize
1.0 - 2.0
Questionable — investigate further
2.0 - 4.0
Good — acceptable for service
> 4.0
Excellent — clean, dry insulation
Common issues: Low IR readings caused by moisture in conduit (drain and dry), contaminated terminations (clean with solvent), damaged insulation during wire pull (inspect and repair).
