Choosing your marine contractor can
be more important than any other contractor you may
need. Why? Because the marine construction industry
is largely unregulated. No building codes for marine
contractors, No true building permits. Nobody to check
the work of the contractor during or after construction
to make sure it meets quality standards.
Some see that as an opportunity to take advantage
of customers. We see it as an opportunity to educate
them.
Here are some tips to help you choose the right marine
contractor:
Take your time.
- Q) Should I get References?
We highly recommend that you see the work of
any marine contractor you consider for your project,
and "ask around" about their reputation.
Call the Better Business Bureau. Ask to visit the
contractor's office, if they have one. Then, learn
the rules. Is an Army Corps of Engineers and/or
Department of Environmental Protection permit required?
Visit their websites to find out, or let us handle
your permitting needs.
- Q) Is All Treated Wood The Same?
All wood is not the same. Pressure treated (PT)
wood is treated to different levels.The chemical
treatment used in pressure treated wood is call
Copper Chromated Arsenate, or CCA. Most hardware
and home improvement stores carry pressure treated
lumber which has 1/4 pound (.25 lb) of chemical
per cubic foot of wood. Marine treated lumber is
more heavily treated, and the following are guidelines
for choosing the proper treatment levels. For ground
contact or salt water splash, use a minimum of .40
PT lumber, which has 60% more CCA than .25 lumber.
For fresh water immersion (such as fresh water bulkheads),
use a minimum of .80 PT lumber. For brackish water
immersion, use 1.0 PT lumber. For saltwater immersion,
use 2.5 PT lumber. This lumber, at 2.5 pounds of
chemical per cubic foot of wood, has 10 times the
chemical treatment of .25 boards.
- Q) What Board Dimensions Should I Use?
Board dimensions are very important. 2" x 8"
boards are much stronger than 2" x 6"
boards when used for stringers.
Make sure you know the dimensions and treatment
levels for the boards to be used on your project.
Grades of wood - boards come in different grades.
#1 grade boards are stronger and have fewer knots.
#2 grade boards are less expensive, and are well
suited for dock substructures and for bulkheads.
Make sure you know which grade will be used for
any decking so you get a fair comparison among bids.
- Q) What Size Pilings Should I Use?
Pilings come in different sizes. They should be
well seated in the ground as piles that are not
long enough may lead to problems. Inadequate pile
length may allow your bulkhead to bow out or your
dock to sink. Find out the diameter, treatment level,
and the length of the piles to be used in your project.
- Q)What Type Of Hardware Should I Use?
Boards that attach to supporting posts such as piles,
and are a part of the substructure of docks, should
be attached with large bolts - 3/4" diameter.
This type of construction is significantly stronger
and will last much longer than using nails alone.
Galvanized nails will eventually rust and weaken
in a saltwater environment, so they should not be
the only support for the stringers and decking.
Has your contractor specified these materials in
his/her proposal?

- Q) What is creosote?
Creosote is the name used for a variety
of products: wood creosote, coal tar creosote, coal
tar, coal tar pitch, and coal tar pitch volatiles.
These products are mixtures of many chemicals created
by burning of beech and other woods, coal, or from
the resin of the creosote bush.
- Q) Do I Need A Permit?
Since many townships and jurisdictions have different
rules and regulations concerning marine construction
The only way to be for sure is to contact the Army
Corps of Engineers and/or Department of Environmental
Protection.
