Abstract

My senior design project will embody many disciplines from the engineering profession.

In particular, my project will demonstrate modern construction based engineering techniques that I have learned throughout my career at southeastern.

For this project I will fully design a multiple family home that will resemble a traditional New Orleans style home.

Project Will Include

Rough design sketch Construction estimate Detailed project schedule Property and structural drawings

(preformed on AutoCAD) Property analysis

Site Analysis

Investigated different types of structures

Took basic measurements to assist in design

Researched current building code in different areas to insure proper design for structure in this area.

Site Analysis contd.

The site I choose for my project is in Lakeview.

Lakeview is a community in New Orleans and was hit hard by hurricane Katrina and because of this all construction on new homes in this area must be raised.

Lot size: 50 x 145

6910 ORLEANS AVE NEW ORLEANS, LA 70124 (LAKEVIEW)

Piliminary Design

When building a house in New Orleans engineers face several building requirements and constraints.

All new homes build in New Orleans (Lakeview area) must be raised.

The height someone must build their home is based on FEMA BFE (base flood elevation) requirements.

The BFE for the area my building is between 1.5 ft – 3.5 ft.

Base Flood Elevation (New Orleans)

BFE (Lakeview)

Design contd.

Through my investigations and research I decided the suitable height for my structure should be 4ft or 48in.

Using this elevation will ultimately decrease the structures chances of being devastated by flooding.

To achieve this elevation proper foundation support is critical.

Footings

Footings for each post will consist of 24”x24”x12” concrete block pads with #4 rebar ties for support.

The exterior foundation walls will consist of 24”x24”x12” concrete around the perimeter of the structure.

Due to soil conditions in this area purlins must be utilized to decrease the chance of foundation and structure damage due to the land sinking.

Post and Beam

Posts typically extend from separate concrete footings to beams or girders that are connected to the foundation.

Posts are spaced at standard intervals around the perimeter of the building and at intermediate points beneath the building.

I have utilized a post and beam foundation.

Post

The post will consist of concrete masonry units. (CMU)

The post will consist of 5 CMU stacked with #3 rebar that will secure or tie into concrete pads.

The rebar is used to strengthen the structures foundation.

The post will be filled with concrete for additional support.

The post will support girder beam.

Foundation contd.

Girder

A girder is a structural support which is designed to carry transverse loads, and to transfer those loads to vertical supports such as columns.

The building I have design will use 6”x8” girder.

The girder will be spliced and connected using steal plates located above each post.

Foundation contd.

Floor joist- 2”x12”x20’ using these joist will allow me to span approximately 20’9’’ (16’’oc).

Each floor joist will be connected using joist hangers.

Rim joist- 2”x12”x20’ Sill plate- 2”x8”x8’

(treated) the sill plate will be secured to foundation using 5/8” anchor bolts (24”oc)

¾” plywood for flooring (tongue and groove)

Wall System

Wall studs – 2”x4”x10’ (16’’oc)

Corner post- (3) 2”x4”x10’ King stud- 2”x4”x10’ Header- 2”x6” Top and Bottom Plate-

2”x4”x8’ (double top plate and treated bottom plate)

Windows- 2’x3’ and 6’x6’ Doors- 80”x36”x1 ¾” Center wall

Wall studs- 2”x4”x10’ (staggered)

Top and Bottom Plate- 2”x6”x8’

Roof System

My structure has a Gable Style roof.

Ceiling joist- 2”x8” (16”oc)

Rafter- 2”x6” (24”oc) Pitch- 8/12 Ridge beam- 2”x12” Gable wall studs- 2”x4” Sheathing- ½” plywood Felt paper- 15lb Shingles- Three tab

36’’x12”

Schedule

Scheduling is the process of breaking down a large project into smaller activities to determine the amount of time each activity will take.

Each activities beginning will depend on a previous activity. The schedule will identify the total time duration of a

project as well as each activities time duration Project Name : New Orleans Multiply family home Start Date: 06/03/2013 End Date: 12/27/2013 Total Duration: 208 days Total Working Days : 151 days
