The report gives a clean review summary; the workbook provides the issue-level detail and supporting checks.

Finding Rundown

What the review caught.

Each item is written so the issue can be understood without deciphering vague redline notes.

QC-001 · CRITICAL

Fiber allocation conflict

FST-103 - Canyon View / MDU-201 - Canyon View Apartments
Critical
Expected Design

FST-103: Fibers 25–32; MDU-201 reserve: Fibers 33–36

As Designed

MDU-201 is listed on Fibers 29–32, overlapping FST-103.

QC Concern

Two destinations would claim Fibers 29–32, creating a splice and service assignment conflict.

Recommended Correction

Reallocate MDU-201 to its intended reserve or revise the approved scheme, then synchronize the project records.

QC-002 · CRITICAL

Terminal model / fiber-range mismatch

FST-102 - East Ridge
Critical
Expected Design

EVOLV 6-port / Fibers 13–18 / PON-01

As Designed

EVOLV 8-port / Fibers 13–20 / PON-01

QC Concern

The hardware and fiber range do not match the expected terminal configuration.

Recommended Correction

Reconcile the terminal model, port count, and exact fiber range before release.

QC-003 · MAJOR

PON assignment mismatch

FST-103 - Canyon View
Major
Expected Design

PON-02

As Designed

PON-03

QC Concern

The serving PON does not match the expected assignment.

Recommended Correction

Verify the intended PON and update the relevant design records consistently.

QC-004 · MAJOR

Route quantity variance

AR-01 - Ridgeview Aerial Route
Major
Expected Design

Expected route length: 1,372 ft

As Designed

Design quantity: 1,245 ft

QC Concern

The design quantity is 127 ft low, a 9.3% variance that could affect material or cost quantities.

Recommended Correction

Recalculate from the approved route geometry and reconcile the quantity.

QC-005 · MAJOR

Terminal tail review

FST-104 - Juniper Spur
Major
Expected Design

QC review threshold: no more than 5 pole spans

As Designed

Tail crosses 6 pole spans

QC Concern

The terminal tail exceeds the sample review threshold and needs design review.

Recommended Correction

Review terminal placement and feed path; redesign or document an approved exception.

QC-006 · MINOR

Direction-of-feed notation

PFP-001 - Canyon Ridge
Minor
Expected Design

Arrow oriented toward the serving CO / PFP source

As Designed

Arrow points away from the serving source

QC Concern

The direction indicator is inconsistent with the expected feed orientation and could mislead design interpretation.

Recommended Correction

Correct the direction-of-feed indicator in the working design records.

QC-007 · MINOR

Conduit documentation

HH-301 - Juniper Entry to HH-302 - Canyon View Entry
Minor
Expected Design

Conduit size/specification shown in the design record

As Designed

Conduit size/specification is not shown

QC Concern

The buried segment is missing a construction detail needed for a complete record.

Recommended Correction

Add the approved conduit specification or governing note rather than assuming a size.
