The seven items to quote
Price each one separately. Write "no charge" or "not needed" where that is the answer.
1

Done means
A typed directory card in every panel listed under Site facts: breaker number, poles, rating, and what it serves. Plus which meter feeds each panel. A photo of each card with the dead front on, emailed to Taji and Greg.

2
Measure the orange-outlet ground path to the service ground
Done means
A written yes or no: does a ground path exist from the orange outlets to the service grounding electrode? Readings per outlet with its circuit number. If the path is broken, where it breaks and the price to bond it.
We hand you
Fact 22 orange outlets on the drawings.devices.json
Fact Every orange outlet tested reads "open ground" on a plug-in tester. Neutral to ground floats 30 to 60 V and drifts. Hot to neutral is a solid 121 V.Electrical history lines 45, 83 to 88 (Klein RT210 and AstroAI AM33D, 8/3/26; live room 1/22/26)
Fact No ground impedance or continuity reading has ever been taken.Electrical history line 88
Fact The 1995 design calls for 5 ft copper rods in each machine room, a copper bus, and #2 in 3/4 in conduit to the electrical room "for future connection".Electrical history line 35 (Sheet A-5.1)
Fact The two outdoor rods photographed have clamps and no conductor. Inference The technical ground may never have been connected.Electrical history line 132
Safeguard
An open ground means no fault-clearing path at the outlet. Treat every orange outlet as a shock risk until you have measured it.

One written finding on the buzz
Done means
One page that squares the earlier visit with the measured float: what you measured, whether the buzz is a grounding problem, and whether the open grounds need repair regardless.
We hand you
Secondhand After a licensed electrician (Abe) visited on 9/29/26, a staff member texted: "We did figure out the buzz is not coming from a grounding issue". Unknown What he measured.Staff text, ref 943264; Abe named as a licensed electrician in ref 940598
Fact The 30 to 60 V neutral-to-ground float above, measured before that visit.Electrical history lines 83 to 88
Fact Staff text 9/21/26: "Both mixers get clean signals when going direct in, the loop seems to happen when both sides are on". Inference A ground loop between two grounded systems sharing one split.Ref 941340; electrical history line 97

4
Fix the circuit that trips when it rains
Done means
Price A: find the tripping breaker and the water entry point, label both, report in writing. Price B, quoted after A: repair to wet-location rating with GFCI protection where code requires.
We hand you
Fact 9/6/26: "the rain tripped the breaker". The lounge TV and speakers died. Staff unplugged everything and reset it.Staff text, ref 936762; fault log F-01, F-04
Fact Jon's own words after the reset: "it was working for a while." Inference The fix was temporary.Staff text, ref 936762; fault log F-04
Unknown Which panel and breaker.Not in the fault log or any text
Inference Water reaching a box, conduit or outdoor circuit, or a GFCI doing its job. An overload is unlikely.From fault log F-01, F-04
Safeguard
Rain reaching a live circuit. Until this is fixed, staff should not reset the breaker during rain.

5
Install the exit signs
Done means
A price per sign: hard-wired, emergency battery pack, installed and tested to code, permit if required. Assume 1 to 4 signs; the per-sign price lets the count change after the survey.
We hand you
Secondhand Staff text 9/3/26: the signs are "wired signs and recommended that they're installed by a licensed electrician."Staff text, ref 936160; fault log F-05
Fact The drawings show one exit sign with an emergency pack, on the exterior alley wall.devices.json, device EX-L03
Unknown How many more signs code requires inside.Not in any drawing or text

Move stage lighting off the audio panel, if they share one
Done means
A written yes or no: does stage lighting share a panel or feeder with the orange outlets? If yes, a price to move the lighting.
We hand you
Secondhand Staff who tested the panel in March 2026 reported "the lights and the audio are on the same panel".Electrical history line 51
Fact The 1995 design kept lighting and HVAC off the technical power panel.Electrical history line 35

Each panel name opens its record in the register.
Zinsco main gearFact Labeled 240 V. The 2024 inspection report records "120/240 volts", 200/400 A, and ticks both single-phase and 3-phase.

Inference Transformer isolation modules on the mic-closet leg of the Catapult split are recommended in every diagnosis branch, after the ground bond. The buzz investigation lists bonding first, then Radial RX4M modules "if anything remains", as the permanent isolation.Buzz investigation notes, lines 17, 21, 23
Fact The buzz sits on channels 2 and 20. Channels 1 and 16 on the same path are clean.Buzz investigation notes, line 13
Phantom-power test, channels 2 and 20
Turn phantom power off on channels 2 and 20 at the desk. Listen.
Turn phantom power back on. Listen again.
Write down whether the buzz changed. If it drops with phantom off, the noise is getting in through the phantom circuit.
On the capture list
Item 14: neutral-to-ground volts at three orange outlets, lights on and lights off.
Item 15: AC volts between the GX chassis and the Trident chassis.
Item 16: swap Catapult output 2 to output 1 at the GX and listen before and after.
