The final design of protective works can proceed once the general plan of protection has
been selected. The final plan should Include a layout drawing, construction details, and
materials specifications. A complete alignment of the structure should be established as
early as possible. Advantage should be taken of adjacent shore protectIon works If
possible. Enough room should be provided for the specified minimum slopes if building a
structure to protect the lower slopes of a streambank, known as a revetment. As soon as
the alignment is established, quantities can be estimated for establ ishlng equipment and
materials requirements.

Access roads and borrow areas should be Identified on the plan. Local contractors and
local officials can provide Information on sources of material and load restrictions on
streets and highways. The use of heavy equipment on residential streets can result in
severe damage to the pavement.

Another important consideration is the selection of the proper equipment to do the work.
Utll Ize the contractor's experience to establ ish the best use of equipment and the nx>st
efficient operation.

Contracts for shore protection works delineate the responslbll ities of both parties, the
owner, and the contractor. The contract should be based on plans and specifications and
Include prices for the estimated quantities of work. It Is important that both parties
fully understand the scope of work. t1Bids" i.e., prices, should be obtained from a number
of contractors to help obtain the work at the lowest prIce.

specifications should be provided to or by your contractor. This should Include some, If
not all.. of the following:

*
