EPICS: Engineering Projects in Community Service Habitat for Humanity Projects

Habitat for Humanity Bringing families and communities in need together with volunteers and resources to build decent, affordable housing" - HFH International The HFH EPICS team tasks are to design systems and structures to minimize home construction and energy costs.

Habitat for Humanity HFH team works on the National, State, & Local Levels Multi-Institutional Projects  Notre Dame  Ohio State  Wisconsin-Madison

Purdue’s Habitat Team National Teams  Homeowner Surveys (NDB)  Construction Tutorial (Tutorials) Local Teams  Headquarters and Training Facility (HQ)  Restore Database Inventory Management (Restore)

Homeowner Surveys National Database Team Team Members Jeff Ross Noah Solomon John Horst Arthur Thompson

Problem Statement Problems for HFHI  No centralized survey administration and data collection system. Some local affiliates do their own surveying, but data is not shared.  There is no concrete quantitative data, currently, to show the benefits of the Habitat program to the community, both locally and nationally.  Homeowner information and responses must be securely collected, transferred, and analyzed to be in line with Habitat’s organizational mission.

Methodology Proposed Solution  Having a centralized secure server database for survey information and homeowner responses  Homeowner ID’s will be requested from the server but will be kept in paper records as to ensure the security of the information being recorded.  The web-based program will consist of three main parts:  A Survey Generator  Homeowner Response Collection\Input  Statistical Analysis

Technical Solution The current program relies on a single centralized database to hold the surveys, responses, and a list of questions and answers. It also relies on a web application to act as the front end to the database. HFHI standards are to use Microsoft products. We have adhered to HFHI standards. We are using ASP.net and MS SQL for this tool.

Tasks Completed  Beta Version Written (Spring 2004)  Reestablished communication (Fall 2004)  Design Documentation (Fall 2004)  Server up and running (Fall 2004)  Team has software (Fall 2004)  Documentation for all Previous Design Steps (Fall 2004) Outstanding  Version 1.0

Version 1.0 Pending approval from the project partner the following system will be implemented and delivered in Week 12 of Spring 2005:  User Management System (2 User classes)  National (1)  Local (~1700)  Each user level has different rights  National: Make Surveys, Enter Data, Export Data  Local: Data Entry

Next Steps Meeting with Professor Haurin at OSU Receive Feedback from IS dept at HFHI Start implementing design specs (Week 1-7) System Testing (8-12) Targeted Delivery Week 12 Spring 2005

Tutorials Team Team Members Aaron Rueth John Hostetler Hannah Mugford Richard Bowerman Construction Tutorials

Introduction Affiliates need a professional grade construction tutorial geared towards their volunteer base. Also wish to improve volunteer efficiency by giving them a solid background in their area of contribution.

Project Overview Construction Tutorials Project  Tutorial Template  Webpage  Reference Card  Tutorial Generator  Review Process  Feedback & Comment Forum  Revision and Update System

Progress Tutorial Template  Assess usability of current template  Testing the template on groups  Surveys to collect data University of Wisconsin-Madison  Four page on-site reference card  Currently six completed (Drywall, Siding, Trim, Interior Doors, Painting, Shingling)

Progress Tutorial Generator  Started this semester  ASP.NET and C#  Graphical User Interface  Information Entry  Currently working on HTML creation  Beta version complete in Spring 2005

Conclusion This semester, we came up with an overall view of where our project was headed and what was needed to delivery a project that could be continually revised and updated. The Tutorial Generator is the first phase in the automation of this project. After the completion of the generator, we will focus on the other systems involved in our project.

Headquarters and Training Facility Headquarters Team Team Members Jaime Alexander Dan Rorick Tim Chou Josh Copeland

Overview Problem: Habitat for Humanity of Greater Lafayette has outgrown their space. They need a place to continue construction during the winter months. Also, they would like to consolidate restore and offices. Goal: Our objective is to develop a feasibility report on a new training center/office building for the Greater Lafayette area Habitat for Humanity

Project Information Technical Progress:  Problem Identification  Specification Development Current Phase in Progress: Conceptual Design Documentation Completed in the EPICS design process:  Project Charter  Tech Appendix  Executive Summary

Project Planning Next Semester: Complete Conceptual Design  Decision Matrix of Requirements  Design Decision Table  Choose Design Approach Deliver Feasibility Report to HFH Lafayette, March 2005

Conclusion Team Headquarters is a few short weeks away from delivering the feasibility report to our Project Partner. Therefore, the objectives outlined are attainable and will be completed on time.
