Designation M133. Such piles shall not be driven until they have dried sufficiently to prevent leaching of preservatives into the receiving waters. A / I nF WAsy, C� = �� ,� �.;..: �G ` D.A.

All piles are to be driven at least one foot (1 ft.) into the very dense "Salmon Springs Drift" strata to the elevation as directed by the engineer. All pile driving shall be done under the full time super- vision of the engineer. e) Piles shall be driven continuously to the final tip elevation once driving has commenced. The driven piles shall not vary from the required alignment by more than 1/4" per foot of pile length, nor shall thr final location be in excess of three inches (3") of the design location. All broken, shattered or splin- tered piles shall be removed at the contractor's expense. f) Piles shall be driven with a single acting pile driver having a driving capacity of 15,000 ft. - lbs. of energy per blow. Jetting or pre -drilling will not b: permitted without the engineer's approval. g) Piles shall be cut off at the elevation indicated on " the drawings. h) The engineer will provide all staking for the Proje.._ in accordance with Section 1-05.5 of the specifications JF RENTON ENGINEERING DEPARTMENT LOGAN AVENUE BRIDGE L; 0"g4'v/,TIQNS DESIGNED_ _ _._. p DA-1 MAR 31 1'972 _ i FILE NC DRAWN------ --� f�1_r AS SHOWtN FIELD er+Ox-_.
