Construction Documents Skill

At a Glance

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:

1. Bill of Materials (BOM): Structured material list with quantities, part numbers, and suppliers extracted from verified design calculations.
2. Installation Sequence: Code-driven ordering of construction activities with trade assignments, prerequisites, and inspection hold points.
3. Commissioning Checklists: Pre-commissioning test procedures (hydrostatic, megger) and system startup procedures with acceptance criteria.
4. 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.

Input:  BlueprintPackage (drawings + calculations + BOM + safetyReview)
Output: BOM spreadsheet, installation sequence, commissioning checklists, O&M manual

BOM Generation (CONSTR-01)

Extracting Materials from Design Specifications

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:

1. Parse P&ID drawings for pipe sizes, fittings, valves, and equipment tags
2. Parse SLD drawings for conductors, conduit, panelboards, and protective devices
3. Cross-reference with CalculationRecord outputs for exact sizing (pipe NPS, conductor AWG, equipment ratings)
4. Apply material specifications from design basis (ASTM pipe grades, NEC conductor types, equipment model numbers)
5. Add supports, hangers, and insulation per ASME B31.9 (pipe) and NEC 300 (conduit) spacing requirements
6. Include consumables (welding rod, solder, tape, sealant, fasteners)

Standard BOM Columns

Every BOM must include these columns:

Column	Description	Example
Line Number	Sequential identifier by category	100, 101, 102...
Item Description	Engineering description with specification	"Carbon steel pipe, 3" SCH 40, ASTM A53 Gr B"
Part Number	Manufacturer part number (if applicable)	"VIC-77"
Quantity	Count or measured amount	150
Unit	Unit of measure	EA, LF, SF, SET
Unit Cost	Estimated cost per unit (if known)	$12.50
Supplier	Preferred vendor or manufacturer	"Ferguson"
Notes	Installation notes, alternatives, lead time	"Per ASTM A53 Gr B, 21-day lead"

Material Categories

Organize BOM by category with line number ranges:

Category	Line Range	Contents
Pipe and Fittings	100-199	Pipe by size/material, elbows, tees, reducers, flanges, unions, couplings
Valves	200-249	Gate, globe, ball, check, butterfly, control valves by size and class
Equipment	250-299	Pumps, CDUs, heat exchangers, chillers, cooling towers
Electrical Equipment	300-349	Transformers, UPS, PDUs, panelboards, switchgear
Cable and Conduit	350-399	Conductors by type/gauge, conduit by type/size, cable tray, fittings

Insulation	450-499	Pipe insulation, duct insulation, firestopping
Consumables	500-549	Welding rod, solder, joint compound, tape, sealants, fasteners

Multi-Size Item Handling

For items that come in multiple sizes (e.g., pipe with fittings), create a separate line item for each fitting type and size:

100  Carbon steel pipe, 3" SCH 40          — 150 LF
101  90-deg elbow, 3" SCH 40 BW            — 12 EA

Installation Sequence (CONSTR-02)

Code-Driven Ordering Principles

Installation sequence is not arbitrary — it is driven by building code requirements, trade coordination needs, and inspection hold points.

NEC Article 110 (General Work Requirements):

• All electrical equipment must be installed per manufacturer instructions (110.3(B))
• Working space clearances must be maintained during and after installation (110.26)
• Equipment grounding must be complete before any conductor is energized

IPC Chapter 3 (General Regulations):

• Rough-in inspection required before concealing piping (jurisdictional)
• Pressure testing required before insulation application
• Final inspection required before occupancy

ASHRAE 90.4 / Data Center Commissioning:

• Factory Acceptance Test (FAT) before equipment delivery
• Site Acceptance Test (SAT) on equipment delivery
• Integrated Systems Test (IST) before occupancy

Prerequisite Notation

Installation steps use prerequisite notation to enforce ordering:

• [PREREQ: item X complete before starting]

  — hard dependency

• [HOLD: Inspection Required]

  — jurisdictional inspection point; work stops until inspector approves

• [TRADE: E/M/S]

  — trade assignment (Electrical/Mechanical/Structural)

Pre-Commissioning Checklists (CONSTR-03)

Hydrostatic Pressure Test (IPC 312.5)

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:

1. Isolate system from permanent equipment (remove pressure relief valves, install temporary caps)
2. Fill system with clean water, vent all air from high points
3. Pressurize slowly to test pressure
4. Record initial pressure and time
5. Hold for 15 minutes; record pressure at 5-minute intervals
6. Pass: pressure drop less than or equal to 5 PSI over 15 minutes
7. 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.

Test parameters per IEEE 43:

Parameter	Systems up to 1000V	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).

Test Equipment Calibration

All test instruments must have current calibration certificates:

Instrument	Calibration Interval	Standard
Pressure gauge	12 months	ASME B40.100
Megger/insulation tester	12 months	NIST-traceable
Multimeter	12 months	NIST-traceable
Torque wrench	12 months	ISO 6789

Documentation Requirements

Each test must document:

• Project name, system identification, drawing reference
• Test date, ambient conditions (temperature, humidity)
• Technician name and license/certification number
• Test instrument make, model, serial number, calibration date
• Test parameters (pressure, voltage, duration)
• Results with pass/fail determination
• Technician signature and date
• PE review signature, license number, and date
