Part 3 - Execution

3.01 Preparation:

  1. All surfaces that are to receive adhesive applied mechanical identification such as Pipe, Duct, and Equipment nameplates should be clean and dry prior to application.

3.02 Installation

  1. Pipe Markers:

    Identify all piping on this project as described, except piping which is concealed and/or not accessible. Identify piping concealed by ceiling tiles, floor tiles and, crawl spaces. Piping outside, on roof, above grade, and within parking structures shall also be identified. Only piping located within walls or inaccessible areas need not be identified. Install pipe markers on long straight runs every 20 feet. Install pipe markers above and below every floor penetration and on either side of every wall penetration and, insure there is at least one marker per pipe in every room. Install pipe markers at every valve, branch and, any change in piping direction. Install pipe markers so they are visible for a normal standing position.
  2. Valve Tags:

    Identify all valves on this project as described except drain lines. Attached tags using solid brass chain and "S" hooks so they are easily visible but do not obstruct the operation of the valve. Provide a valve schedule to the engineer for approval. After schedule is approved install an aluminum frame in every room containing valves and installed the approved valve schedule detailing the valves within each room.
  3. Equipment Nameplates:

    Identify all equipment, the location of concealed equipment and the disconnects and controls of all equipment as described. Attach these nameplates with double faced 2 mil permanent acrylic adhesive.
  4. Duct Markers:

    Identify all ductwork on this project as described. Install duct markers every 20 feet on long straight runs. Install duct markers at all floor and wall penetrations and near all connected equipment. Install duct markers at all branches and changes in direction of the duct so it is easily traced.
  5. Underground Tape:

    Identify all underground piping on this project as described with a continuous length of detectable tape. If tape cannot be continuous then it must overlap by ten feet at any end. If piping is buried more than 36" below the finished earth surface then two continuous lengths of tape must be buried as described.
