Detailed walkthrough
This quest begins upon investigating one of the many Garrahan excavator posters in Appalachia, usually, the one located in the parking lot of Garrahan Mining Headquarters upon getting close enough to trigger the marker for the miscellaneous objective for it.

Travel to the Garrahan Mining Headquarters and enter the building. Access the computer at the receptionist's desk and read the entry "Memo: Excavator Queries" to trigger the quest. From there, head downstairs to the Research & Development (R&D) room to access the project manager's terminal, but be aware of the hostile robot enemies inside the building, including Protectrons, Mister Gutsy, and Robobrains.

Once in the R&D Room, accessing the project manager's terminal and select the option "Excavator Module Blueprints" to download the plans for crafting Excavator power armor. Then use a power armor station to craft the armor parts onto the power armor chassis. Note that the minimum level for crafting and equipping the power armor is 25.

A level 25 suit of Excavator power armor will require a power armor chassis and a total of 36 black titanium, 30 gears, 12 glass, 6 nuclear material, 36 oil, 26 rubber, 60 screws, 20 springs, and 102 steel to craft. If materials are hard to come by via scraping various junk, try claiming a public workshop that has mineral deposits needed for crafting the parts.

Once the armor has been crafted onto the chassis, equip the chassis and use the terminal in the R&D Room of the Garrahan Mining Headquarters to have the armor scanned and registered to complete the quest.
