questions to help you assess if the contractor's past performance equals his claims. After selecting a
contractor, plans and specifications should be prepared before work begins. You can provide them to the
contractor or have the contractor prepare and submit them to you for approval. In either case, these
documents should contain some or all of the following items [U.S. Army Corps of Engineers (1979)].
1.
The location of the work site should be clearly identified in relation to identifiable references, such
as the highway right-of-way, the shore, and your house. The limits of work should also be clearly
delineated.
2.
A survey showing property lines and the elevations of devices and fill according to a standard
datum, such as MLW, MLLW, LWD, or IGLD.
3.
A typical cross section(s) including all dimensions, slopes, connections, and other necessary
design details.
4.
A materials list showing estimated quantities required for the entire job.
5.
The limits of excavation and backfill as they affect measurement and payment.
6.
Other construction details, such as weep holes, construction joints, flank protection, anchorage,
splicing and bracing, filters, and arrangement of cables and fasteners.
7.
Pile construction details, such as number of piles, their length, driving requirements, cutoff
elevations, and framing details.
Sample specifications describing requirements of the work are shown in Figure 24.
The sample specifications given below are typical of those needed for a contractor to build
several shore protection structures. They are supplied only for illustrative purposes and are not intended
to be exhaustive lists of particulars (guide specifications) from which specifications for any particular job
could be developed. Additional information given in the text or the suggested reading list could also be
used to supplement the specifications given below. Specifications for other materials not mentioned
could be developed from information given in the text or provided by manufacturers and suppliers, or
from federal, state and local government agencies.
SITE PREPARATION
The required work consists of furnishing and placing a stone revetment, a timber bulkhead, and a
steel sheet pile bulkhead as indicated on the drawings and herein. All work shall be conducted so as to
prevent damage to structures which are to remain and to maintain or improve the aesthetics and ecology
of the site.
