Excavation Systems Planning, Design, and Safety
Preface
his book represents a culmination of knowledge that I have gained through 10 years of working as a construction engineer for contractors constructing pipelines and water and wastewater
treatment projects and 16 years of developing an engineering firm that provided shoring design to contractors and shoring manufacturers.
During the construction years I estimated excavation projects,
planned
the work, and worked in the trench
with the workers. In the engineering
years I was fortunate to be able to work with hundreds
of
underground contractors, the largest and the smallest, all over the United
States. This wide range of exposure to level of knowledge and approach
to excavation work and safety that these contractors had was priceless. During that entire
period I never worked on the “other side of the street”
for owners and civil design firms, but I was continually
working with them on excavation work issues. Later in my
career I worked with lawyers to help them understand excavation issues.
Throughout this career I accumulated my basic knowledge and
understanding of how all parts of the excavation industry functioned
and interacted. All of us involved in the industry pulled basic
excavation and safety technology information from wherever we could find it.
We searched it out, adapted it to our needs, and used it to construct safer and more
efficient excavations. I saw across the board
that new entrants to the excavation industry faced a huge task in
trying to acquire basic knowledge of the industry.
I saw the construction side looking for better and more
efficient ways to do things and the civil design side looking for ways to accept what they were
proposing to do based on current state-of-the-art technology and accepted practices. At
the end of a career it is easier to look back and see where it all came from
and how it all fits together. It is not so easy to write it down. This book is an effort
to assemble what I learned in one place and add some perspective so that everyone involved can better understand excavation work.
