5.1.11 Perform survelliance to assure that any tendency to segre-pation is corrected by shoveling stones into mortar, not mortar over stones.

5 1.12 Perform surveillance to assure that bedding planes of con-crate are approximately horizdntal. -

5.1.13 Perform surveillance to assure that concrete is consolidated to maximum practicable density, is free from rock pockets

~

and fits tightly against all form surfaces and embedded items.

5.1.14 Perform surveillance to assure that correct vibrators are used, i.e. Internal high-frequency type with a speed of not less than 6000 revolutions per minute.

" 5.1.15 Perform surveillance to assure that vibrators are inserted vertically at approximate two (2) foot intervals and with-drawn slowly to prevent formation of pockets and that vibra-tors are not used to transport concrete. Vibrators shall penetrate the layer being placed and the underlayer as well.

Adequate vibrating, melding and blending of succeeding batches will be assured by survelllance.

5.1.16 Perform surveillance'to assure that cdntact of vibrators with reinforcing steel is minimized and that form or surface vibrators are not used without Engineer's approval.
