Engineering and Contracting 443 The plan of pier No. 4, the damaged pier,as furnished to the contractors by the engineer,called for piles to be sawed off at grade, eleva-tion— (see Fig. 1). They were then tobe tilled in to their tops with gravel or brokenstone, and the pier was to be built in an opencaisson resting on a 4-ft. wooden grillage con-sisting of IJxlJ-in. timbers. This constructionwas carried out, the pier was completed andthe bridge was accepted and paid for. On August 31 the engineer wrote to the jointboard, advising the use of riprap at the fender,and stated that for protective purposes riprapshould also be placed on the river side of the ^a 16 0.

On the same date he asked the con-tractors for a proposal to place riprap as aboveoutlined, and a proposal was made to the jointboard by them to place riprap for $ yard, lo the extent required and as di-rected by the engineer. This proposal wasaccepted on Sept. 4, and about cu. yds. ofriprap were placed about the fender pier, theSomerset abutment, and pier No. 1; but noneabout piers Xos. 2, s, 4 and 5. The writer had doubts about the sufficiencyof the quantities of riprap placed, owing to theprevalence of the teredo, and wrote the resi-dent engineer to that effect. However, the en-gineer did not think it necessary to riprap thepiers. Consequently the work of riprapping wasstopped, and the responsibility of not protect-ing the grillages and piles was placed on thecnsinecr, who has never shirked this re-spon
