  1. Reference telecon Mr S Signore and F/L F Ling 10 April 1961, ROZCC letter dated 23 March 1961 and AMC (RCAF) letter dated 6 April 1961, construction drawings S-13-1104-1 to 5, S-22-1048-1, S-22-1048-5 and S-22-1049-1, the following observations are considered pertinent:

    1. Drawing S-13-1104-1

      1. The wall reinforcing for the heat exchanger will not be provided by the electronics contractor. Since Detail "B" in ROZ-1042-2 is not acceptable to CCE(RCAF) an alternative support must be provided by the building contractor. This was agreed to by W/C Martin CCE at a Gap Filler meeting held t GEEIA HQ 24 FEb 1060.

      2. Elevation 2 measurement from single duct to extension of lower duct should read 4'6" not 5'2" as shown.

      3. More detail should be provided to cover the passage of the waveguide and the anchoring of pipe sleeves throught the steelox wall, particularly regarding the mounting plate. Suggested mounting plate dimensions to be specified on the drawing are 24" x 18" x 1/4".

    2. Drawing S-13-1104-2

      1. The ramp required from grade to radar equipment building double doors is not shown. The ramp is essential since cabinets must be uncrated outside and moved into the building on rollers.

    3. Drawing S-13-1104-4

      1. Legend: Louvre control motor 120v 1 phase (By Others). It is assumed that "By Others" does not apply to the radar installation contractor. This applies particularly to motors A-7 in the radar building

      2. Removal of APU #1 for repair would necessitate moving of APU #2 if access doors were as presently located. It is suggested that the louvre openings could assume the dual function of door and ventilation.

    4. Drawing S-13-1104-5

      1. No detail regarding "connections to transfer switch" has been shown for sites without commercial power. S/L Anderson was advised by ATSC that this was actually underway 17 March 1961.

    5. Drawing S-22-1048-5

      1. The storage space provided for diesel fuel appears adequate for only an 8 day supply. Varying degrees of accessibility may well make this of doubtful adequacy.

      2. The same question of "Unmanned" Operation and doubtful accessibility indicates that two diesel fuel pumps with a crossover switch for equalization of use would be more satisfactory.

    6. Drawing S-22-1049-1

      1. If the pole and transformer structure is located in positions C1 or C2 the access to the equipment building may be obstructed.

      2. A road should be provided from Perimeter road to ramp leading into electronic equipment building.

  2. Tower foundation layouts should be included in these drawings. It is essential that tower footings be located accurately so that waveguide and conduit runs may be designed.

  3. Drawings submitted are acceptable if they are amended in accordance with 1a(1), 1b(1), and para 2. The other observations are submitted for your information and consideration.

  4. Acknowledgement of incorporation of mandatory items designated in para 3 is requested.
