PROPOSAL NUMBER: 8413
1. Statement of Understanding
The Request for Proposal 8413 describes the requested services as Geotechnical Testing
Service. Our service of this contract would be supplied from our Fort Collins Office – our Field
Department would provide the materials testing and construction observation services while
our Geotechnical Engineering Department would provide the geotechnical consulting and
pavement design services.
We understand the City of Fort Collins will use this contract for materials testing and
observations services such as soils and aggregate sampling and testing, asphalt sampling and
testing, concrete sampling and testing (air, slump, compressive strength) and specialized
services as needed. We have experienced and certified technicians who are available on a full-
time or part-time basis as required to perform the above testing as well as structural steel weld
and bolt inspection, epoxied anchor inspection, masonry observation and sampling, drilled
pier installation observation, and reinforcing steel observation. CTL|Thompson makes a point
of maintaining an experienced staff with the capabilities and certifications to meet all of our
clients’ needs from our Fort Collins office.
We understand the geotechnical engineering component of the contract would involve the
planning and execution of subsurface testing, performance of laboratory testing and the
preparation of pavement designs. Our reports would identify the subsurface conditions and
provide a variety of pavement options describing the risks related to each one.
Proposed Approach to Meet the City of Fort Collins Needs
Our Fort Collins Branch consists of highly qualified, certified, and experienced technicians and
engineers. The resumes included with this submittal are for some of the employees of the Fort
Collins office that would be assigned to work on the City projects. It will be our approach to
provide all of the materials testing and engineering work locally in order to provide a
streamlined set of contacts and a more consistent product. However, a few specific laboratory
tests may need to be performed at our Denver laboratory due to specialized equipment needs.
Having worked on numerous on-call contracts in the past, our Fort Collins Field Department
is comfortable with and capable of helping the City manage field testing requirements and
budgets. Our approach to meeting the City’s needs may involve an initial meeting with the
engineer and/or inspector to discuss the test types and frequencies with regard to the
quantities of materials being placed. During this meeting, we would determine a going-in
position for when and how the testing will take place to make sure all required tests will be
performed for each material. We would then work closely with the engineer, inspector, and
contractor throughout the project to ensure all required tests are covered within budget and in
a timely, efficient manner.
Our approach to the geotechnical engineering portion of the contract would be to evaluate the
project site and provide alternatives, which could then be evaluated by the owner and design
team to assist determining efficiencies and overall cost savings without impacting the
performance of the improvements. Our approach to evaluating subsurface conditions at the
project site would be to provide alternatives and associated risks in order for the owner and
design team to select the option most suitable for their needs and budget considerations.

PROPOSAL NUMBER: 8413
Our goal is to work as an integral part of a team consisting of our staff, City personnel,
contractors, and suppliers. We believe the keys to successful projects include constant and
open communication as well as a commitment to resolving problems as quickly as possible.
Our approach would not involve the need for any sub consultants – we have sufficient expertise
and staff in our Fort Collins Office. And, if necessary, we can pull additional staff or expertise
from our 6 other offices in Colorado and Cheyenne.

Inspection & Materials Testing
Our Fort Collins office offers a full range of soils and construction observation and materials
testing services to assist the City of Fort Collins in sampling, testing, and documenting the
quality of construction processes and materials. Our Field Department currently has 10
technicians that are 100% dedicated to field testing and are cross-trained to provide flexibility
and quick response times for the City’s projects. We have additional staff that are ACI and ICC
certified in our engineering departments, who can be utilized for last-minute call-ins. We
understand the demands of an aggressive schedule and will be able to respond to last-minute
testing requests (within 2 hours of the request and usually sooner). We are also able to adjust
our schedules so that technicians can stay on site longer to test additional concrete trucks or
make additional site visits as needed. We are committed to helping the City and contractors
produce a quality product so will spend whatever time is necessary on the site. In addition, we
can call on our engineers to make a site visit for further input and expertise.
We have a phone line dedicated to field scheduling and have added the ability to schedule via
email and text messaging. Messages left on any of the above media are sent to multiple
individuals, which promotes quicker response times to schedule requests. We have also
increased our field administrative staff in 2016, which allows for quicker report turn-around
and response time to questions on existing reports.
We have staff available full-time for questions regarding laboratory test results, and we have
experience providing recommendations to municipalities and contractors regarding soil
compaction methods, asphalt placement techniques, and concrete strength issues. Our

Our firm is a leader in rigid and flexible pavement design and management technologies. CTL’s
Pavement and Construction Management Group is fully capable to perform preliminary
surveys, provide design of pavement rehabilitation, complete Pavement Justification Reports
and Design Reports, and develop materials portions of project plans. We routinely perform
destructive testing to evaluate pavement conditions including pavement and base thickness
and to collect samples of the base and subgrade soils. CTL is also fully capable of evaluating
the pavements structural capacity based on field investigations and laboratory testing. Our
pavement evaluation and design capabilities include lime/fly ash stabilization mixture design,
pavement distress investigations, profilograph testing, finite element and elastic layered
computer analysis, life cycle cost analysis, asphalt concrete mixture designs (Superpave and
Marshall), and development of long-term maintenance.

4. Sustainability Commitment
CTL Thompson is dedicated to minimizing our impact on the earth by managing our resources
more efficiently, decreasing our energy use and reusing or recycling materials.
When we perform a geotechnical investigation our sampling techniques use a barrel sampler
with brass liners. The liners are reused for other investigations, thus conserving the amount of
new brass liners needed for this type of investigation and sampling.
During construction, we sample and test ready mixed concrete used in construction. The
specifications require that we make compressive strength cylinders to verify concrete mix
properties. We also sample grout and mortar during masonry observations. We use reusable
molds for mortar sampling and concrete/grout cylinder molds that are made from recycled
products that are also biodegradable.
We recycle the concrete from our cylinders after they are tested as well as our grout and mortar
samples by collecting them in a separate dumpster. They are then picked up and delivered to
the Barker Pit for crushing into recycled concrete base. We recycle the soils and asphalt that
we test by filling holes in our parking area. We recycle steel from the helical piers we test.
We built a custom fog room for curing concrete cylinders that recirculates the water for much
reduced water usage.
We have reduced the amount of solvents used when testing asphaltic materials by using
ignition ovens for asphalt extraction. The minimal amount of solvents used is handled by safety
clean which recycles as much of these as practical.
We believe in repairing equipment first and only discarding as a last resort. We repurpose
parts of old equipment and use it to repair other equipment.
We believe in maintaining our fleet to reduce emissions. We repair vehicles as long as it is
feasible then distribute old ones to employees. We are committed to purchasing new vehicles
that are lighter with better fuel efficiency or that provide the flex fuel option. We schedule our
field technicians to minimize drive distances to save on fuel and emissions. Finally, we instruct
our employees not to leave trucks idling while onsite to cut back on emissions.
The CTL Thompson office in Fort Collins recently replaced our old bulbs with LED lighting,
used recycled carpet tile for the building flooring, uses fresh air cooling in summer as much as
possible to minimize the air conditioning usage. We installed programmable thermostats for
greater efficiency and a window in our laboratory for heating, cooling and natural daylight.
Finally, we have xeriscape landscape to reduce water usage.
We have made a concerted effort to reduce paper consumption. The majority of our reports
and correspondence is now done electronically. We only produce hard copies when requested
by a client or as a backup to the electronic stored information when necessary. Plans for
construction are viewed online and large document sets are not common. CTL | Thompson
recently started converting field data acquisition during construction observation and
inspection services from paper to electronic format which has greatly reduced the amount of
paper consumption. Documents are saved to pdf format and sent via email whenever possible.

We are currently working toward eliminating our paper file storage by creating a web-based
storage system, and employees are encouraged to save documents electronically and not print
them.
Employees in Fort Collins were provided metal water bottles to reduce paper and plastic cup
usage. As with most companies, we also provide receptacles for recyclable consumables (office
paper, ink, aluminum, glass, etc.) for our employees to use which are emptied weekly by
Gallegos Sanitation.
CTL Thompson has made it a priority to explore new, innovative ways toward greater
sustainability in the office, laboratory, and in the field and will continue to do so in the future.
