replacement work); maintaining water supply and
schedule critical during work;
investigated alternatives for
water main materials; and,
construction in three
phases. Project complication involved the following: leaking valve (Phase III test but not I/II);
space for work (2 contractors);

regularly changing schedule (highway
contractor has incentive to finish early);
existing support rod Ø changed each
phase; and,
pipe support spacing. Presentation summary includes the following: water main replaced on a changing
schedule with ductile iron pipe and
steel pipe;
victaulic © Style 31 and Depend-o-
