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~ constructi:)n detai Is, and
materials specifications. 1\ complete al ignment of the structure should be established as
ear I y as poss i b Ie. Advan"!-age shou I d be taken of adjacent shore protect ion works if
possible. Enough room should be provided for the specified minimum slopes If building a
structure to protect the 100Ier slopes of a streambank, known as a revetment. As soon as
the al ignment is establ ishej, quantities can be estimated for establ ishin~~ equipment and
materials requirements.

Access roads and borrow an,as shou I d be I dent; fled on the p I an. Loca I 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 considera1ion is the selection of the proper equipment to do the work.
Uti J Ize the contractor's ex~erlence to establish the best use of equipment and the roost
efficient operation.

Contracts for shore protection works del ineate the responsibilities of both parties, the
owner~ and the contractor. The contract snould be based on plans and specifications and
include prices for the estimated quantities of work. It is important that botn parties
fully understand the scope 01 work. lIBids" i.e., prlces~ should be obtainec from a number
of contractors to help obtair the work at the lowest price.

*

A typ i ca I cross
connections.

~ectlon

indicating

dimensions,

s lopes,

arn:lngement,

and

*

Quantity of materials (per linear foot, per protection unit, or per job).

*

Relation of the foundation treatment with respect to the existing ground.

*

Relation of the top of the proposed protection to design high-water and low-water
data.

* The limits of excavation and backfil I as they may affect measurement and payment.

*

Construction detal Is such as weep holes and pervious materials associated with
them.

*

Location and detal Is I)f construction joints, cutoff stubs~ and end treatment.

*

Connections and braclllg for framing of timber or steel.
