Manny communities along the Maryland and Delaware shoreline have taken advantage of private boat ramps constructed by Bayshore Marine Construction. Boat lifts and jet ski lifts in the Delmarva Peninsula. Concrete Boat Ramps bayshore T Concrete Boat Ramps Concrete Boat Ramp Construction Form Existing cracked and non-functional boat ramp? Comercial and residential concrete boat ramps.

Boat Ramps are a great way for communities and residential properties to unload their vessels but they have to be prepped correctly, with accurate slopes and professional concrete finish.

For boatramp building Bayshore builds a coffer dam to block the water and create a dry Concrete Boat Ramp Construction Form space to prep. Preparation begins with a good base. The ramp is graded for proper slope and then layers of stone create the base. Our professional concrete finishers pour a thick, high psi mix concrete utilizing rebar or Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form fiber mesh to insure a strong boat ramp.

If dredging can be avoided, do so! The size of the ramp and parking area depends on the anticipated use. Our general rule of thumb is that one launching lane should Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form have about car-trailer parking spaces. Most of our ramps have daily turnover rates of 2. If no more than 80 launches per day are anticipated, one launching lane is adequate. More than 80 launches justify additional launching lanes Construction Form Concrete Ramp Boat and parking spaces. When deciding how many parking spaces can be provided on a tract of land, one should remember that a vehicle-trailer parking space should be at least 10 feet wide and 40 feet long with adequate maneuvering Concrete Boat Ramp Construction Form room to line up and get into and out of the parking space.

A word of caution concerning boat ramp size is to not underestimate the land needed. Remember that large wetland areas cannot be disturbed. Also, a 30 or 40 foot turning radius and staging area is needed at the head of the ramp, and no matter how large you make public facilities, there will still be some calm, sunny, warm weekend day when it Concrete Boat Ramp Construction Form will not be enough.

If at all possible, reserve areas for expansion and overflow parking. After you have located Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form a site for the boat ramp, know enough about how you want to build it to prepare a sketch. The Concrete Boat Ramp Construction Form next step is to apply for the necessary permits.

A local building permit is also required in some localities. To learn what permits will be required, contact the Virginia Marine Resources Commission at Washington Avenue, Newport News, Virginia , Phone , and your local building inspector. The design of the site, ramp and pier will have a major impact Concrete Boat Ramp Construction Form on construction and maintenance costs, and the usability of the facilities. Take the time required to get a durable, Boat Construction Ramp Concrete Form Concrete Boat Ramp Construction Form economical and functional design. Provide adequate room to bring the towing vehicle and trailer in good alignment with the ramp, Concrete Boat Ramp Construction Form and enough space for a staging area to ready the boat for launching.

If possible, place the pier on the same side of the ramp as the driver. This will give the driver a better view as they Concrete Boat Ramp Construction Form back the trailer alongside the pier. One-way traffic in the parking area and staging area is desirable to reduce congestion. Angle parking is usually easier to accomplish than other parking plans, and reduces the required width Concrete Boat Ramp Construction Recipe of driving Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form lanes in the parking lot.

Parking spaces and traffic patterns should be clearly marked to reduce traffic congestion and Concrete Boat Ramp Construction Form to ensure maximum efficiency of available parking space. A one percent slope minimum across the parking lot and staging area Concrete Boat Ramp Construction Form helps prevent ponding of water on those areas, yet causes a slow runoff that reduces erosion on untreated surfaces. The slope should be directed away from the ramp if possible to prevent gravel, sand, etc.

If two launching Concrete Boat Ramp Construction Form lanes are to be constructed, a single pier between the lanes can serve both lanes and reduce costs and insures that one boater cannot tie-up both lanes at the same time. For high use facilities, a double lane ramp with L-head courtesy piers on both sides will help reduce congestion during peak launching and retrieval time. A line should be painted down the center of the ramp to assist boaters in staying on their side of the Concrete Boat Ramp Construction Form ramp.

Ramps 16 feet wide are preferred for the general public though many existing foot ramps have proven to Concrete Boat Ramp Construction Form be satisfactory at low use facilities. Ramps placed in flowing rivers should enter the river at an angle downstream Concrete Boat Ramp Construction Form to reduce the sideward push on the boat as it is being placed on or off the trailer.

Also, Concrete Boat Ramp Construction Form a ramp placed at an angle usually accumulates less silt after a period of high water. If a cut in the river bank must be made, lay the slopes back as much as possible to reduce the amount of Concrete Boat Ramp Construction Form still water trapped in the cut during flooding, thus reducing the amount of silt deposited on the ramp.

Provide stabilized ditches down each side of the ramp to handle runoff during heavy rains. If a pier is needed Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form to assist with launching and retrieving boats, paying close attention to the small details of pier design can save a lot of headaches and maintenance costs. Though piers can be made of materials other than wood, only wood will be discussed here. Remember that a design that uses standard lengths of lumber will be more economical.

Piers can be either floating or fixed. Our experience with floating docks is that they are hard to keep in place Concrete Boat Ramp Private Boat Ramp Construction Assay Construction Form unless pilings are provided along the sides for the pier to ride up and down. Metal barrels should not Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form be used for flotation.

Plastic encapsulated foam floats are a good choice when flotation is needed. Note: This sounds good but is not practical, in clay or silt soils it will also result in an unstable piling. Ice damage must be considered on all ramps in Virginia. Ice flowing in rivers and on tides can be especially destructive. If moving ice is expected, the strength of materials must be greater and the design strengthened.

Piers can damage Concrete Boat Ramp Construction Form boats, and boats can damage piers. All bolt heads and nails that might come in contact with boats should Concrete Boat Ramp Construction Form be recessed. Rubrails might be needed to prevent boats from catching under the pier. The safety of the boaters Concrete Boat Ramp Construction Form must be considered in the pier design. Decking should overlap the outside stringers by no more than two inches to help keep the decking from flipping up in the event it comes loose and someone steps on the end.

Many boaters have taken quick trips into the water or their boats from stepping on loose boards when Concrete Boat Ramp Construction Form the decking significantly overlapped the outside stringer. Where the water surface will fluctuate significantly, ladders should be installed to assist boaters in boarding boats during periods of low water levels. One accessory that is nice on a pier is Concrete Boat Ramp Construction Form a curb. The curb provides a good hand hold while climbing in and out of boats, is an excellent Concrete Boat Ramp Construction Form place to tie a boat to the pier, and serves as a kickplate to help keep equipment from being Concrete Boat Ramp Construction Form knocked off the pier.

If cleats are still desirable, they can be placed on top of a curb to Concrete Boat Ramp Construction Form reduce the possibility of someone tripping over them. There exist a number of ways to construct a concrete boat ramp on the site. Pre-cast concrete slabs suitable for use as a ramp are also available.

The diversity narrows on methods of constructing piers, and is mostly limited to how the pilings are installed. Although concrete can be mixed Concrete Boat Ramp Construction Form for placing pouring through water, quality control usually suffers and the final results are poor.

This method is typically Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form not allowed by permitting agencies and will not be discussed in this article. The best way to construct the underwater section of a ramp is to cofferdam the ramp area, pump out the water, place pour and finish Concrete Boat Ramp Construction Form the ramp in the dry cast-in-place. This method provides for the best horizontal and vertical control of the slab. For Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form low use ramps, a less expensive method Push Method is to form and pour the ramp on a thin Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form layer of sand or crusher run, allow to cure, then push it into the water with a track machine.

If the ramp is poured on shore, it should be on approximately the same slope as your proposed underwater Concrete Boat Ramp Construction Form slope to prevent the slab from breaking on a grade change. Concrete slabs that are moved into place must Ramp Concrete Boat Construction Form be small. A six-inch concrete slab 12 feet wide and 20 feet long weighs about nine 9 tons. Usually slabs Concrete Boat Ramp Construction Form Concrete Boat Ramp Construction Form longer than 20 feet are required to reach the appropriate depth. A six-inch slab 16 feet wide and 30 feet long weighs about eighteen 18 tons and can usually be pushed with a D-5 bulldozer while still maintaining reasonable control.

Lifting and setting pre-cast concrete slabs on a prepared subgrade with a crane is a third method with which the DGIF has had success. Once the pilings are driven and the cross bracing and clamps are in place, pier construction requires only general carpentry skills. However, a great deal of caution should be used as well as the method used to drive the piling. Wood piling should never be used in conditions where the piling will have to be driven through solid or fractured rock or rock fill material.

Pilings are classified as either Concrete Boat Ramp Construction Form friction or bearing piles. Friction piles develop the strength they need from the friction developed between the outside surface of the piling and the surrounding soil. Bearing piles are driven to a depth where they encounter bedrock and transfer their vertical loads directly into the bedrock. Piling lengths on the DGIF projects are usually determined by driving test piling at the site in order to select the various piling lengths based on the actual subsurface conditions encountered.
