8.1 Are there any externally non-standard mounted fixtures to the shelter (there should be no fixtures other than the ECU or possibly fiber optic modem all weather enclosure).

8.3

Does an all-weather access road and turn-around at the equipment shelter site exist as shown on Standard Drawing?

Note: Variation may exist in accordance with Standard Drawing.

8.4 Inspect that the equipment shelter will not flood and that proper drainage from the shelter exists. The final elevation of the equipment shelter foundation is not critical, however this final elevation must assure that the shelter will not flood.

8.5 Are shelter foundation cable vault covers provided as depicted on the Standard Drawing?

8.6

Does power/telephone pedestal with power termination box and telephone termination box exist as depicted on the Standard Drawing? Note what type of box is present (Wood Cement etc...).
