EWB-USA Overview

A non-profit humanitarian organization established to partner with developing communities worldwide in order to improve their quality of life

Involves the implementation of sustainable engineering projects, while involving and training internationally responsible engineers and engineering students

EWB-USA History

Founded by Dr. Bernard Amadei, at the University of Colorado at Boulder, in April 2000

First Project – San Pablo, Belize water supply system Mobilized 8 University of Colorado students, forming

the founding members of the first chapter Demonstrated the potential of professional and student

engineers working together

EWB-USA Mission Statement

To partner with developing communities to improve their quality of life through the implementation of environmentally sustainable, equitable, and economical engineering projects.

In the process of working to advance developing communities, EWB-USA promotes the development of globally aware and internationally responsible engineers, students, and professionals

Residents of the Hogar


Water Tank & Tower Installation Goals:

Elevate the 2500-liter tank currently on ground Locate tower for this tank Construct the concrete tower footings Isolate the current tower for continued facility water service. Install the tank

Elevate the new 5000-liter tank Construct the concrete footings for the second new tower. Install the tank

Connect tanks


Water Tower

Site Assessment

First time to see the site

Check physical dimensions

Connect to people at the Hogar


Water Tower

Introduction to Nicaraguan engineering students

Start foundation excavation


Water Tower

Adjustments to a prefabricated tower

Nicaraguan students brought skills and equipment


Water Tower

Placement of 5000 L water tank


Water Tower

Setback:Leg of tower directly over an unpressurized water main

Solution:Rotated tower legs


Roof Stabilization System Goals:

Stabilize the roof system to prevent tiles from shifting or falling during a seismic event.

Metal tension strapping to be attached into the roof frame and concrete of the exterior wall.


Roof Stabilization:

700 feet of CS16 galvanized steel tension strapping donated by Simpson Strong-Tie


Roof Stabilization:

Bolted strapping to concrete wall


Roof Stabilization:

Straps must be installed in tension


Electrical System goals:

Examine and correct the unsafe existing circuits.

Consider the exposed junction boxes.


Electrical

Nicaraguan electrical contractor assessed students with electrical work


Electrical

Students measured and cut all conduit


Electrical

Created individual light switches for each room
