It will be necessary to saw cut a slot in each block to <br /> receive the flashing and hold it in place. Refer to the attached sheet entitled Change Order EV-O1 for a detailed breakdown <br /> of cost. <br /> Item 2090 -Sheet V25 of 124 shows the electrical meters and current transformers attached to the Eugene Water and <br /> Electric Board (EWEB) primary and secondary source transformers. EWEB does not allow the electrical meters and <br /> current transformers to be attached to their primary and secondary source transformers. To satisfy EWEB, we propose to <br /> relocate the electrical meters and current transformer cans to the east wall of the electrical building. Refer to the attached <br /> sheet entitled Change Order EV-02 for a detailed breakdown of cost. <br /> Item 2100 -The City of Eugene building inspector reviewed the drawings after they were bid and required an additional fire <br /> extinguisher be added to the electrical building.

After <br /> reviewing the calculations, the Engineer of record concluded that the slab should be 5-inches thick rather than 4-inches <br /> thick. Refer to the attached sheet entitled Change Order EV-04 for a detailed breakdown of cost. <br /> Item 2120 - Sheet V 11 of 124 shows details for the plates to be used to mount the canopy to the wall of the electrical <br /> building. Sheet VS of 124 shows that the center mounting bracket for the canopy on the south and north side of the building <br /> interferes with the internal wall. It will be necessary to manufacture new plates that are wide enough for the bolts to clear <br /> the wall and to provide enough room to install the nut and washer.
