Independent Survey Reveals Opportunities and Challenges for U.S. Construction Industry Executives

Williams Scotsman International, Inc. (NASDAQ: WLSC), a
leading provider of modular space solutions, today announced the
results of an independent study it commissioned to examine the
near-term future of the construction industry and gauge the
satisfaction of its customers. Conducted by McGraw-Hill Construction
Research, the survey revealed that respondents identified "geographic
expansion" and "leveraging technology" as the two greatest
opportunities when they think about the future of their companies. The
study also used the "net promoter" score, a measure of customer
satisfaction by Bain & Company, to determine 93 percent of Williams
Scotsman's customers would refer the company to others.
More than 400 Williams Scotsman customers were interviewed via
telephone in March of 2006 and asked to rank their greatest perceived
opportunities and challenges. Key findings include:

-- 72 percent believe geographic expansion is an important factor
in their future growth

-- 65 percent said leveraging technologies for production,
distribution and processing presented a growth opportunity

-- 86 percent of Williams Scotsman's customers said finding
qualified personnel and staff presents the greatest challenge
or obstacle

"While we've heard from our customers that geographic expansion
and adoption of new technologies were top of mind, nothing confirms a
trend like a quantitative survey," said Michele Cunningham, vice
president of marketing and business development for Williams Scotsman.
"With our national 86-branch network and recent technology
introductions, we believe we can be responsive to these customer
opportunities."
Williams Scotsman remains committed to leveraging new technologies
to enhance the experience customers have with its products. Just last
year, the company partnered with DEWALT to implement their
SITELOCK(TM) technology to address the ongoing issue of jobsite
security.
"We also found the issue of recruiting qualified personnel of
great interest," said Cunningham. "Many of our customers have told us
they are leaning more and more on experienced, full-service vendors
like Williams Scotsman to fill in the gaps created by new employees
that often necessitate a learning curve and time to build
competencies."
The customer satisfaction section of the study was designed with
the following goals in mind:

-- Benchmark the attributes of current Williams Scotsman products
and services

-- Assess customer retention and loyalty

-- Gauge Williams Scotsman's position among competitors within
the industry

-- Determine how various customer segments view Williams Scotsman

The study showed that when choosing a particular modular space
company, customers view the following factors as their most important
decision criteria: delivery process/logistics; price; inventory;
quality; and service. Ninety seven percent of customers report a
positive opinion of Williams Scotsman and 93 percent said they would
make a strong recommendation for the company to others.
McGraw-Hill Construction designed and managed the survey in
compliance with CASRO (Council of American Survey Research
Organizations). Respondents were screened based on the following
criteria:

-- They had used a Williams Scotsman product within the last year

-- They are the primary decision makers within their organization
for mobile space and container needs

-- They have sufficient familiarity with at least three mobile
space companies in their geographic market so they would be
able to rank them in order of preference
