An interview with Randy Williams, SR/WA
1. Tell us about yourself and your IRWA career.
I have been a real estate appraiser since 1977 and hold the
MAI and SR/WA designations. I retired (for the most part)
at the end of 2018, although I am still active in the IRWA
both in teaching and by being the International Relations
Chair for 2019-2020. I also represent my employer JLL at
various functions like IRWA’s Annual International Education
Conference. My IRWA career is approaching 35 years. During
my career, I have served as a Chapter President, Region Chair
and finally, I served as the International President of the
Association in 2011-2012.
2. When did the idea of creating a book focused
on presenting an overview and new alternatives
to corridor valuation first come to mind?
It started four years ago at our Conference in San Diego.
Bonnie Roerig, MAI, AI-GRS, was chairing the International
Valuation Community of Practice. At the Valuation meeting,
she discussed the idea of creating a book on Corridor
Valuation. Scott Robinson, MAI, SRA, AI-GRS, AI-RRS, the
Appraisal Institute President-Elect at the time, approached
Bonnie after the meeting and expressed interest on partnering
with us on this publication. At this same meeting, Bonnie
asked for my opinion. I suggested we take up Scott on his
offer and move forward with a steering committee. She agreed
upon the condition that I too would serve on the steering
3. What was the main purpose and goal behind
the creation of this book?
Our main purpose was to add to the body of knowledge
about valuing corridors. Corridors are very complex and
there are multiple—and sometimes opposed—theories/
techniques on valuation. Our goal was to present these
multiple techniques as tools to understand valuing corridor
properties. As such, the book does not place any technique
Virtually any city of any size in North America has some
kind of corridor within its territory, be it utility, rail or
other. That means that not only appraisers, but also property
agents will deal with a corridor issue sometime in their
career. So we believe this publication is of value to every
real estate department in every municipality and utility
company. Research confirmed that a current text of this type
was not available.
4.Describe the steps you took during this
We initially formed a steering committee to decide the
content and shape of the book. We were fortunate to have
Richard Marchitelli, MAI—an appraiser with extensive
corridor valuation experience—to chair the committee.
We met face to face as a steering committee only one time.
After that, we met electronically and by conference call. In
the end, we outlined the topics necessary and produced a
Request for Proposals (RFP) for authors.
We received a large number of proposals for the various
chapters. All eight members of the steering committee
