Source set

28 pages:12 architectural/structural/electrical pages,9 mechanical pages,7 plumbing pages. The files are preserved under work/samples/temple. Source names, byte sizes and SHA-256 fingerprints are in data/sources.json. Architectural native text and page images were extracted; raster M/P sheets were rotated upright, rendered at108dpi and OCRed with Tesseract. Key schedules and drawings were visually checked against OCR. OCR is evidence assistance, not a quantity authority.

Quantity provenance

• Counted/scheduled: opening tags and sizes, visible equipment/fan tags, scupper positions and architectural fixture/appliance locations, subject to conflicts listed in RFIs.
• Measured approximation: wall lengths and duct/trunk routes read at schematic precision. Architectural drawing calibration uses the70ft and62ft11in dimension strings. Individual endpoints are rounded to practical estimating feet. Do not treat them as survey coordinates.
• Derived kit: one body, stop/trap/trim/support set per appropriate fixture. Purchased factory equipment is represented as an assembly; its internal motor, PCB, valves and fasteners are not exploded unless purchased separately.
• Provisional: omitted routes, controls, circuits, services, offsets, product choices and fabrication details. These are explicit estimating decisions, not engineered design.

Pipe logic

Coordinates are feet east/south from the west exterior face/front garage grid. A route's net length is sum of horizontal point-to-point segments + explicit vertical height + connection allowance. Most fixture water branches carry10ft of drop and2ft of connection allowance from an overhead distribution system. Main routes reflect the PP101/401 topology but are estimated, not pixel-exact vector measurements. Fixture rough-ins and changed architectural fixtures need field coordination.

Water fittings: branch elbows are route turns plus two riser bends; straight couplings are estimated at one per10ft; tees are one per hot/cold fixture branch and match the receiving header and branch size. End adapters/stops belong to fixture kits; main valves/reducers are separate. Water insulation and supports follow installed pipe quantities. CPVC is modeled as a consistent CTS system pending the material-family RFI. Solvent/primer is a discrete allowance.

DWV routes carry one4inch building main, sanitary group branches and individually added fixture branches; four2½inch vent risers and separate2inch vent branches are provisional. The supplied isometric depicts two visible roof termination symbols; the estimate carries four for the completed architectural fixture scheme. Final wet-vent grouping may reduce these; no claim of four drawn VTRs is made. DWV fitting counts are estimated by group and diameter; they are not a complete connectivity-validated spool graph. Pipe fitting take-outs, invert slopes and actual elevations are not deducted/calculated. Underground trench/bedding are separate.

The PP601 FD-1 in the master shower is treated as that shower's drain, not a separate fourth shower/floor drain. If a separate floor drain is intended, add it and its trap protection. The fifth scheduled shower outlet is carried as a second master valve/head. Pantry dishwasher drainage is a separate indirect-waste provision because no sink is shown at that appliance. Its final receptor/trap/vent arrangement must be designed.

Duct logic

Rigid trunk lengths follow scaled rectangular paths. Surface area =2(width+height)/12length. Wrap covers straight surfaces plus25%for fittings and10%installation waste. Four-foot R8 flexible supply tails are counted separately and remain below MH601's6ft limit. Return terminal connections use4ft rigid allowances. Elbows, transitions, branch junctions, boots, terminal dampers, cleats and supports are separate. Final gauges, reinforcement, free-area sizes, static pressure and approved flex neck sizes need shop design. D-01 is an undefined150CFM device, carried as separate equipment/connection scope; it is not silently counted as a supply grille.

Electrical logic

Room device counts are provisional manual symbol tallies/completion allowances. They are not represented as a completed code-spacing audit. Circuit register groups general receptacles, wet areas, lighting, appliances and equipment. Net cable =Manhattan home-run plan length +22ftcombined rise/drop +6fttermination allowance + explicit branch distribution.14/3 also carries300ftof fan/switch traveler allowance. Exterior wet conductors/conduit are separate from dry interior NM home runs. Circuit protection and wire/breaker sizes remain engineering holds.

The panel-space check verifies only that proposed breakers fit: main60spaces,subpanel24spaces, plus main subfeed and surge reservations. It does not calculate demand, voltage drop, ampacity adjustments, short-circuit rating or service adequacy. Switch station boxes provide66gangs for62switches. Fan motors are excluded perA105; fan-rated rough boxes and switch conductors are included. Mechanical power/disconnects are owned byElectrical; mechanical control wiring is owned byMechanical. Appliance prices include positioning only, with all utilityconnections inMEP.

Purchasing and cost ownership

Purchase quantity =ceil(net(1+waste)/pack)pack. Material cost =purchase quantityunit material rate. Labor hours =net quantityperson-hours per unit. Labor cost =hours*burdened rate. Direct line cost =material +labor +equipment/services. Labor productivity includes the named item's installation task only; testing/supervision/rentals are explicit separate lines. For pipe/duct, handling/straight installation is inLF labor; fitting installation is inEA labor. No separate subcontractor lump sums are layered onto these components.

Purchase sheet aggregates existing BOM purchase quantities by item code/unit/rate; do not sum both tabs. Repeated factory items are bought individually, while consolidated linear/sheet/fastener lines are rounded to package multiples. No vendor SKU is fabricated: custom/owner-selected items retain generic specifications and a release hold. All unit prices areUSD and unquoted unless marked a public benchmark. Public benchmark means price observation or analogous basis, never a project quote. Estimator adjustments are disclosed in the source register.

Scope resolution still needed

This is a detailed estimating BOM. It cannot be a fabrication-ready BOM while fixture plans, electrical design, AHU schedule, roof details, energy report, civil design and truss/wall shop information are missing or inconsistent. Refinement should replace provisional rows with approved routes and vendor assemblies, retaining IDs and cost ownership to prevent double counting. The included RFIs and estimating overlays make that next step reviewable.
