Question: we assume that this project is exempt from Maine State Sales Tax.

Please advise if it is not exempt.

Answer: Excerpt from Maine Revenue Service Bulletin:

CONSTRUCTION CONTRACTS IN GENERAL

When constructing new buildings, repairing existing realty or remodeling, a contractor is selling the materials used in the construction job after they are affixed to the realty. Therefore, the contractor is selling real property, not tangible personal property. Except as noted in (3) be-low, a contractor must pay the tax as a consumer on the purchase of materials and supplies used in fulfilling any kind of construction contract.

CONSTRUCTION CONTRACTS WITH EXEMPT ORGANIZATIONS

§1760 (61) provides an exemption from sales and use tax on items which will be physically in-corporated in real property of an exempt organization. This exemption only applies to lumber, hardware, doors and windows, nails, insulation and other building materials actually affixed to realty. Tools, wearing apparel, consumable supplies, machinery and equipment used by the con-tractor are taxable even if purchased specifically for the exempt job. Construction contracts with any of the following agencies or organizations qualify for this exemption:

i. The Federal Government, the State of Maine or any of their agencies;

ii. Any city, town, plantation, district or political subdivision of the State of Maine; and

iii. Any organization holding a valid exemption certificate issued by Maine Revenue Services. (See Rule 302 for more information on exempt organizations.)

The contractor would purchase materials being incorporated in the real property tax free by furnishing the supplier with a "Contractor's Exempt Purchase Certificate" in the form set forth at the end of this bulletin.

A certificate must be filed for each project stating the location of the project and the name and exemption certificate number, if any, of the exempt organization.

Question: Specification section 221519, paragraph 2.06 outlines an Air Purification System for the provision of Grade "D" breathing air at points of use at locations indicated on the drawings. There are four

(4) breathing stations shown on drawing P-206 (designation B), two stations in Paint Room 168, one in Paint Storage Room 169 and one in Stripping Room 112. Note 3 on drawing P-206 and spec 221519, para.

2.06. B state the breathing air shall be accomplished by using filters on the compressed air system (see detail 2/P-502).

Major concerns are: 1. The specified compressor is oil flooded, should be oil free to support breathing air.

2. Use of steel piping for the CA system is at risk of developing rust in the event of an issue with the air dryer, not good for breathing air. 3. Grade "D" breathing air should be through a purifier with a series of filters, catalysts and CO monitors/alarms, distributed thru copper piping. Use of filters alone is highly discouraged, this is confirmed by Kaeser Compressors Inc. Technical Support (800-777-7873).

Specification 221519, paragraph 2.06.C states that local and remote audible and visual alarms for the Carbon Monoxide Monitoring System shall be provided where indicated on the Contract Drawings, yet none are shown on the drawings.

Please clarify all of the above.

Answer: Discussions with the compressor manufacturers indicates that the use of the oil-free compressor in lieu of the oil- flooded compressor is not a requirement. Bid compressor as specified. Breathing Air Filtration system is capable of filtering any particulate concerns from piping system. Bid piping system as indicated. Both filtration systems indicated in specifications are capable of producing Grade D breathing air. The Bullard Series 41 filter will not remove carbon monoxide (CO). The system will not have CO in it unless it is ingested by the compressor. The compressor supply will be monitored for CO as indicated on drawing P-205. Visual and Audible alarms will be present at the locations on the drawings where breathing air is indicated.
