1. Multistory Office Building
ET 494
Professor: Dr. Cris Koutsougeras
Advisor: R. Edward Rode’
Students: Michael Rebstock and Zac Venable
Construction Concentration

2. Objective / Deliverables
Complete Load Calculations
Finalize Working Drawings
Quantity Take-Off
Complete Project Estimate
Complete Project Schedule (Primavera)
The purpose of our project is to display skills learned throughout the ET curriculum specifically dealing with:
Surveying
Scheduling/Planning (Primavera)
Estimating
Engineering Calculations
Design Building using AutoCAD

3. Introduction
The goal is to design-build a multistory commercial office building
The building will have specific design requirements
The investigation of a LEED certified building will be analyzed

4. Selected Location More land for a cheaper price
Centered in an Industrial area
Close to US 190, I-12, I-55

5. Site Layout

6. Building Codes International Code Council 2012
Permits
Occupancy Classification
High-Rise Buildings
Means of Egress
Accessibility
Interior Environment
Exterior Walls
Roof Assemblies and Rooftop Structures
Structural Design
Soils and Foundation
Glass and Glazing
Electrical
Mechanical Systems
Plumbing Systems
Elevators
Special Construction (Awnings/Canopies)
Concrete
Steel

7. Building Materials Building will be constructed using:
Steel Beams/Columns/Joists
Precast Concrete Wall Panels
Composite Metal Flooring Deck
(2nd,3rd,Roof Slab)
Constructed using Autodesk Revit

8. LEED Investigation Precast Concrete Panels for Exterior/Interior Walls
Metal Stud Crete (MSC)
Benefits
Conventional Panels lbs per square foot
MSC Panels lbs per square foot
Lighter Dead Loads on Beams/Columns
Exterior Concrete/ Interior Steel in one assembly

9. LEED Investigation Aluminum Door Framing/Assembly Benefits
Exterior/Interior Doors
Curtain Walls
Interior Office Partitions
Benefits
Optimize Energy Performance
Recycled Content
Regional Material
Lighter than Steel which reduces loads on columns/beams
