Construction Schedule

           The Avon Boardwalk Redesign is a civil/ architectural project as opposed to a product design project. Instead of filling out inquiry sheets for needed parts to create a product, I have compiled a schedule of materials which detail what items and how many of each I will need to supplement my design, if built.  After determining that the design calls for 168 of the concrete pilings that I designed, I calculated the amount of concrete that is needed to construct one piling.  I then multiplied this amount by 168 and cam to a total of 10.57 sh tons of concrete.  I then went back to my piling detail and calculated how many of the fasteners are needed to attach the joists to the piling in addition to calculating the number of joists the design calls for.  After I calculated the total amount of joists, I found the surface area the boardwalk will cover.  I used Trex Transcend, the initial product I chose for my intended solution.  I used the company's installation PDF to determine how many additional decking fasteners my design calls for.

Rationale Report

Rationale Report 

Introduction

The nature of the final design must exemplify functionality, sustainability, endurance, and accessibility as well as maintaining aesthetic appeal.  The beachside walkway must also adhere to the specifications and limits set forth at the start of this project.  To satisfy these qualities, I designed five alternate solutions of walkways and support systems.  The first is a support system consisting of concrete supports with a plastic composite decking which I will refer to as “Concrete and plastic” for simplicity.  The second is a tall wooden piling support system with wooden planking which will be called “Wooden system”.  The third is a concrete support system with a concrete surface, which will be referred to as “Concrete block”.  The fourth design is a shorter wooden piling system with a concrete surface called “Short wooden pilings”.  The fifth alternate solution consists of pavers stones that are installed onto an even surface no higher than two feet off of the ground that will be referred to as “pavers”.  

Concrete and plastic

My first design, “Concrete and plastic” is an elevated design supported by concrete pilings.  These pilings go 15 feet underground and are  shaped as pictured below:     

                                           

The dimensions of the pilings are 18 feet wide by 1.5 feet deep. 

 The pros of this support system are as follows:

-Fireproof

-No maintainence required

No rotting or warping

-Very strong

-Texture/color options

-The cons of this support system are as follows:

-Non-traditional look/less aesthetically pleasing 

-Longer time to construct

The deck upon the pilings are created with a plastic composite material. This material is created from recycled plastic materials, benefitting the sustainability quality needed in this project.  The planks are a grey color and have a grained surface pattern to mock wood.  The planks are 1.25'' x 5.5'' and have a square edge.  The planks can be seen pictured below:

The pros of this decking are as follows:

-Very durable

-Eco-Friendly

-Does not splinter

-Does not rot or warp

-Less maintenance

The cons of this decking are as follows:

-Non traditional boardwalk feel

-Will take longer to decompose if washed away

Wooden system

This design consists of an elevated walkway of Ipe wood on a wooden piling support system.  The support system is wooden trunks that are piled 15 feet into the ground and are exposed an additional 10 feet above sea level.  The support system diagram can be seen pictured below…

                                      

The pros of this support system are as follows:

-Traditional boardwalk feel

-Able to be elevated

-Cost effective

The cons of this support system are:

-Larger quantity of materials needed

-Safety hazard, people may fall off

The decking will be Ipe wood planks.  These plank will be of standard size, about 1.25”x5.5”x18’.  

The pros of this decking are:

-Traditional boardwalk feel

-Natural warmth

-Cost effective

-Biodegradable if washed away to sea

The cons of this decking are:

-Tendency to warp

-Tendency to rot

-Requires high maintenance

-Splinters

Concrete block

This design consists of a support system of large concrete block supports.  The concrete block design can be pictured below…

                                      

The pros of this support system are as follows:

-Strong, can support alot of weight

-Will not weather

-Does not warp

-Does not splinter

-Does not rot

-Requires little maintenance

The cons of this support system are as follows:

-Non traditional “beachy” feel

-Not aesthetically pleasing

This design consists of a concrete treads for the walkway surface.  These treads are concrete cast made planks.  

The pros of this walkway are:

-Durable

-Different color variations

-Different texture variations

-Does not warp

-Does not weather

-Does not rot

-Low maintenance

-Non-slip surface

-Low cost

-Heavy treads that will not be moved by storm surge

The cons of this walkway are:

-Non traditional boardwalk feel

Short wooden pilings

This design consists of wooden pilings yet keeps the boardwalk low to the ground.  The wooden pilings would lift the boardwalk to 2 feet above sea level.  These shorter pilings are of timber that are piled into the ground 15 feet.  The details can be seen pictured below…

                                      

The pros of this support system are:

-Traditional boardwalk feel

-Would allow storm surge to go over the walkway

The cons of this support system are:

-Warping

-Rotting

-Weathering

-Splintering

-Requires maintenance

The surface of the walkway of this design is concrete treads similar to those in the “Concrete block” design.  

The pros of this walkway are:

-Durable

-Different color variations

-Different texture variations

-Does not warp

-Does not weather

-Does not rot

-Low maintenance

-Non-slip surface

-Low cost

-Heavy treads that will not be moved by storm surge

The cons of this walkway are:

-Non traditional boardwalk feel

Pavers 

The fifth and final alternate solution is a simple support system of wooden planks to even the surface for pavers stones.  The pavers serve as the walkway and main component of the design. 

                                      

The pros of the walkway:

-Even with sea level to allow surge from storm to pass over boardwalk

-Durable

-Low maintenance

The cons of this structure

-Non traditional beach feel
