ENGINEER OFFICE, UNITED STATES ARMY,l
NEWPORT, r. l., August L 1870,
Seaed proposals will be received at this office until
SATURDAY, the nth day of September, 1870, at 10
O'Clock NJ, for the construction OF the substructure
of breakwater at Block Island, r. l., for local pur
poses.
1t will begin at point on shore near Sands
Landing, on the southeast part of the island, and
be built out to and along line joining "Clay Head
and "F1ve Foot Rock" Its total length will be
about three hundred (300 feet beyond the low water
line The greatest depth OF water on the line Of the
breakwater is at its sea extremity, where there is
sixteen C6) feet at mean low water. From thence
shoreward the bottom slopes up gradually TO high
water mark, the bottom being smooth sand, under
laid with clay The mean rise and fall Of the tide is
three and one-quarter (31) feet.
The substructure Of the breakwater will be stone
simply dropped into the water so as to form slope
OF three ) base to one Q) perpendicular on the side
towards the sea and one ) base to Q) perpendi-
cuar on the side towards the land and be thirty
1907 feet wide at mean low water level. The work
must be begun at the shore end and be finished up
to mean low water level as it progresses from the
shore.
The stone must be granite OF the best quality so
far as durability is concerned, and in pieces weigh
ing not less than one and one-quarter QAO ton,
without regard to shape except that there must be
no slabs or thin pieces.
1t is believed that this work can be done by ves-
sells unloading their cargoes on the spot In ordi-
nary weather vessels lie in the roadstead with
perfect safety, though there will be times, in the
earlier progress Of the work OF least when much
time must be lost The worst storms are from the
southeast, and during storms from that quarter the
roadstead is untenabe for vessels OF any class.
To complete the whole structure about fifty thou
sand of stone will be required but at present the
funds appropriated will, 1t is estimated, pay for
more than ten thousand tons. Proposals will be
received only for the smaller amount, and no con
tact will be entered into for work to be performed
after the 9Oth day of June, 1871.
Payments will be made monthly, reservng ten QO)
| per ceutum till the contract is fulfilled.
Proposals must state price per ton at which the
stone will be furnished and put in the breakwater,
which price must include all charges whatsoever
against the United States.
The stone must be deposited by the contractor,
under the supervision of engineer designated by
| the undersigned for that duty.
Proposals must state the earliest time at which
work will be begun after acceptance OF proposal.
Work once begun must be prosecuted with all prac-
| tcal diligence.
