Compare the list of equipment sections in the Acceptance Tests and Inspections article with the one-line and equipment schedules, and confirm that every switchboard, switchgear lineup, transformer, transfer switch, generator, and UPS drawn is covered by a section that is both listed there and included in the project manual. Then check that each listed equipment section points back to Section 26 08 00 and carries its own field quality control tests.
Assemble the review package
Gather the electrical one-line, the equipment schedules and room plans, the medium-voltage site distribution drawings if any, the protective device settings or coordination study, the issued Section 26 08 00, and every equipment section it lists (for example switchboards, low-voltage switchgear, transfer switches, generators, pad-mounted transformers, and UPS). Review one piece of distribution equipment from the one-line through its section to the testing list before assuming the rest are covered.
WBDG publishes UFGS 26 08 00: Apparatus Inspection and Testing as a public guide-specification reference (accessed October 21, 2026). Use your project’s issued specification and amendments for the actual comparison; the guide specification does not automatically govern your project. The checklist below is an original suggested review workflow, not a reproduction of the UFGS requirements.
Eight checks to run against the issued set
Use one record per location or system. The CSV contains the same eight prompts plus fields for source revisions, observed evidence, the review owner, the decision, and closure references.
| Check | Sources to compare | Question to resolve |
|---|---|---|
| Equipment list vs. one-line | Acceptance Tests and Inspections article + one-line + equipment schedules | Is every type of distribution and generation equipment shown on the one-line covered by a section on the testing list, with no listed section left in for equipment the project does not have? |
| Listed sections in the project manual | Acceptance Tests and Inspections article + project manual table of contents | Is each section named on the testing list actually issued with the project, using the same number and title? |
| Cross-references back to 26 08 00 | Related Requirements and field quality control articles of each equipment section | Does each listed equipment section say that Section 26 08 00 applies and carry its own field quality control tests, as the section’s designer note asks? |
| Generator testing split | Acceptance Tests and Inspections article + Section 26 32 15 + generator drawings | Where the generator is listed, is it clear which generator tests the testing organization performs and which the start-up engineer performs? |
| Medium-voltage and site equipment | Acceptance Tests and Inspections article + site electrical drawings | If the drawings show pad-mounted transformers, pad-mounted switchgear, substations, or medium-voltage cable, are the matching sections on the testing list? |
| Settings and shop drawings for the tester | Acceptance Tests and Inspections article + coordination study + protective device schedule | Are the settings of adjustable devices the tester will need traceable to a study or schedule in the documents, rather than left undefined? |
| Testing organization and qualifications | Qualifications article + Division 01 submittal requirements | Does the project keep the independent, first-tier testing organization the section requires, and are its qualification and procedure submittals in the submittal register? |
| Reports, acceptance, and energization | Acceptance Tests and Inspections Reports, System Acceptance, and Placing Equipment in Service articles + schedule | Do the sequence of operations, commissioning plan, and schedule hold energization until tests are complete, with the testing organization present when equipment is first energized? |
Worked example: a switchgear lineup missing from the testing list
Illustrative example: the one-line shows a new low-voltage switchgear lineup and two automatic transfer switches. The issued Section 26 08 00 still lists only the switchboard and generator sections from an earlier design, and the project manual includes Section 26 23 00 without any reference to acceptance testing in its related requirements.
Ask the electrical engineer to add Sections 26 23 00 and 26 36 23 to the testing list, and to add the cross-reference and field quality control tests to each of those sections. Recheck the submittal register so the testing procedures for the added equipment are requested before the equipment is scheduled for energization.
Avoid a false conflict
Section 26 08 00 can look complete while covering the wrong equipment. Its list is a set of bracketed choices that are easy to leave from a previous project, so check it against the one-line every time the distribution design changes.
When requirements disagree, follow the project’s document-control and clarification process. Do not assume that drawings always override specifications, or the reverse. Identify the exact sources and request an authorized decision.
Close the issue across the affected documents
Record the location or tag, drawing and specification references, issue dates, observed difference, and the decision needed. Assign an owner and keep the item open until the response identifies the governing requirement. Check the revised drawings and specification references together; a response email alone may leave the issued package inconsistent.
For the overall process, use the guide to drawing and specification conflicts. Mark an inapplicable checklist row with a reason, and distinguish a verified correction from a question that still needs design information.
Where Groundbook fits
Groundbook’s drawing and specification review helps investigate potential disagreements in the documents you supply. Include the relevant specification sections and drawing references, then verify the cited evidence with the responsible reviewers before acting on a finding.
