As-built quantities & weekly progress
Provisional survey-based QS report. Dates come from survey layers, not installation sign-off. Straight, bent and curved sections are measured along the original 3D linework. Polyline bends are identified by plan deflections of at least 10°; both incident edges enter the bend section. Review section limits before valuation. A section is not a manufactured bend fitting.
Location & comparison basis
Automatic target: BESS 33KV DUCTING OFFICIAL SO.dxf, the lower and upper duct layers in the existing model. Each individual duct contributes its length; this is not trench-centreline length or a count of installed cables. Excavation and concrete lines have separate quantities and do not enter the duct completion percentage.
As-built over design
North up · blue = official design, target only · other colours = dated as-built. Grey = unassigned survey date when included. No survey point symbols. Actual 3D levels and line lengths are available by selecting an element in the viewer.
Weekly QS quantities · as-built only
Calendar weeks, Monday–Sunday. Counts refer to contiguous source sections split at survey dates and the straight/bend rule; location boundaries may split them further. Metres follow 3D geometry, including its bends. Curved polylines retain measured chords; splines are sampled using a 1 mm flattening setting. Section counts and metres are not payable fitting quantities.

Weekly comparison against design
New weekly coverage = union of matched design intervals to week end minus the union before that week. Repeated survey coverage is therefore counted once. Dated observations only; unresolved or ambiguous matches cannot establish completion. The remaining figure means design length without dated, unambiguous survey coverage.

Review & exclusions
- Date attribution: dates follow the POINTS* DDMMYY layers of the surveyed points forming each original line. All source vertices are inspected. Point ID prefixes never override layer dates.
- Connections and intermediate vertices: multi-day polylines are split into dated runs. An edge joining an older and newer survey enters the later day (a reporting inference). Intermediate or relayered vertices inherit their own source run; identical shared point handles can carry unanimous evidence to an adjoining line of the same feature layer. A unique nearby point may support attribution within 75 mm, with the next candidate at least 150 mm and three times farther away. Source geometry is never snapped or changed. Inferred sections are identified in the tables and CSV.
- Missing date layers: concrete lines 5968 and 5DB0 have no dated point-layer anchors. Their points are on asb_conc_top; 5968 has IDs beginning 0409, but this is not a dated layer. These lines remain visible when unassigned dates are enabled and are excluded from dated totals.
- Same physical fragment drawn twice: splines 5E22 and 5E23 replace their alternative chord polylines 5E16 and 5E25 in quantities and rendering. The removed duplicate chord length is 3.664 m. Six zero-length source edges are excluded.
- Matching: nearest parallel route in the same duct tier, XY search within 0.30 m and direction within 30°. Near-equal alternatives within 0.03 m are excluded as ambiguous. Sampling uses chords up to 0.25 m. These are matching parameters, not construction tolerances.
- Levels: design is at invert; as-built is at duct crown. This percentage comparison is in plan, with covered design intervals measured in 3D. It does not certify level compliance or installation. Visual pipe diameter is nominal 200 mm.
- Design scope: only the official 33 kV model is used. Embedded design alternatives, other services and terrain do not enter target or quantities. No source revision approval was supplied.
- Section classification: small plan deflections below 10° stay in the straight class. A sharp bend may have measured limits wider than the actual fitting. No radius or true arc length is invented for a polyline.
- Manual notes: the three source notes with date “11/09/025” are not added to the measured totals.
Line schedule · selected scope
Only dated sections in the chosen period, plus unassigned sections when requested. Full E/N/Z end coordinates, supporting point IDs, point layers, association residuals and date rules are in the CSV. An inferred-section count flags provenance, not a date-layer conflict.
