Disclaimer: This March 7, 1972 Tax Counsel letter concerns a lump-sum project for four 190-foot scales, six computer-controlled consoles, a minicomputer, and connecting communications cable. The February 29 request, March 6 telephone-conversation record, and lump-sum contract are not reproduced in the official PDF. The source prints 'trick scales' once and closes with an otherwise unidentified 'refinery rule' note; both are preserved, and no authority is reconstructed from the vague note. Classification depended on how each component was installed and integrated under former Board Ruling 11. Modern weighing and control systems require component-level review under current construction-contractor rules.

Plain-English summary

The lump-sum project was a construction contract for an integrated truck-scale system.

Load-cell columns bolted to concrete foundations and scale-platform sections welded to the columns and to one another were materials consumed by the contractor. The reinforcing bars and poured concrete formed part of that installed scale structure.

The six computer-controlled weightmaster consoles and the minicomputer were fixtures because they were accessories to the scales and part of the integrated operation. Communications cables interconnecting the scales, consoles, and computer were materials.

Common questions

How were the scale platforms and load-cell columns classified?

As materials.

How were the consoles and minicomputer classified?

As fixtures integrated with the scales.

How were the connecting cables classified?

As materials.

Dear Mr. W---:

Your letter of February 29, 197X addressed to Mr. John T. Quick has been referred to us for direct reply to you. You request a ruling with regard to the tax liability under a lump-sum contract, entered into with O---, Inc. Under the contract O--- Inc., is to furnish and install four 190’ trick scales, six computer controlled weightmaster consoles and a mini computer to control the weightmaster consoles with a communications link tying together the scale assemblies, consoles and mini computer. According to our telephone conversation of March 6, 197X, we understand that the scale platforms are delivered to the jobsite in 20’ sections and are installed in place. The 16 load cell columns also are bolted in place on concrete foundations. The platform sections are then welded to the load cell columns and the sections welded together, after which you install reinforcing bars and pour the concrete into the scale platform. Under the above facts, it is our opinion that the contractor installing the load cell columns and the sections of the scale “pan” in place is the consumer of the “materials” under ruling 11. It is our opinion that the computer controlled consoles and the mini computer which are interconnected to the scales by the cable constitute “fixtures” which are an accessory to the

scales and part of the integrated operations. The cables interconnecting all units, in our opinion constitute “materials.” Should you have any further questions, feel free to write to us. Very truly yours, Joseph Manarolla Tax Counsel
