Project Understanding
Background
Two arterials designated as Enhanced Travel Corridors through the City of Fort Collins, both Prospect and
Timberline Roads are critical components of the City’s Transportation Master Plan. The intersection of these two
roadways is utilized by a large number of City residents and visitors on a daily or frequent basis as they travel
from one destination to another using multiple modes of transportation. As Enhanced Travel Corridors,
Timberline and Prospect, and especially their intersection, are expected to optimize travel time, and to be
recognized as high-quality, world-class facilities by users traveling through in a vehicle, on a bicycle or on foot.
The intersection of Timberline and Prospect, and the segment of southbound Timberline Road from Prospect to
just north of Drake Road, were improved in 2004-2005 to meet the needs of the community in the short and
medium terms. The same Interwest Consulting Group team that delivered that highly successful interim condition
project is now prepared to complete the mission. Today, the intersection has already begun to outgrow the
previous improvements, as evidenced by increasing levels of intersection traffic, delays, and increased accident
rates. In 2004, in addition to the interim (current) corridor and intersection design, the Interwest team created a
50% level design for the ultimate corridor needs, analyzing the projected traffic for the corridor and how meeting
the demands of the traveling public will impact the existing businesses, landowners and the natural environment.
Several aspects of that ultimate design were then integrated into the interim condition construction plans.
General Project Description
The Timberline Road Corridor Improvements Project will bring the intersection and corridor to its ‘ultimate’
configuration. Anticipated improvements include a new ‘free right’ turn from eastbound Prospect to southbound
Timberline, additional lanes on southbound Timberline, widening of the bridge over Spring Creek, and
incorporation of a ‘unique landscape identity” by the City’s consultant, BHA Design. In addition to the limits of
the construction project, the required Traffic and Modeling Report will include the intersection of Riverside Drive
and Prospect Road, located one quarter mile to the west. The proximity of these two intersections, and the volume
of traffic that travels through both intersections, results in congestion and delays for which the City is seeking
creative solutions. The limit of the project on Timberline Road also contains the widening of an at-grade railroad
crossing which will require improvement agreements with the Great Western railroad.
The project will be funded through the Building on Basics sale and use tax, enacted in 2005 and has a total budget
of $3.3 Million. The limits of the project are from Timberline Road at Blackbird Drive on the south, through the
intersection of Timberline and Prospect Roads, and including the transitions on the three remaining legs. Design
constraints include environmentally sensitive resources, the constraining width of the Spring Creek Bridge, an
existing railroad crossing, impacts to affected landowners and businesses, and budget. Additionally, the City
seeks suggestions for relocating and/or repurposing the existing the grain silos on the west side of Timberline.
Construction phasing is a critical element in order to maintain the high volume of traffic through this corridor
during construction.
The contract will be an hourly-not-to-exceed contract, and of critical importance to the City is on-time delivery. In
the following section, “Project Issues/Approach”, we will identify the most significant challenges along the
corridor, discuss our approach to each, and describe how our solutions will resolve issues and meet deadlines.
SECTION 2 SCOPE OF WORK
Team Introduction2 of 15
Scope of Work
Timberline Road Corridor Improvements
RFP 7450
Project Issues / Approach
Roadway Geometry:
Issue: Timberline Road is a major arterial roadway and currently has two lanes in
each direction through the Prospect intersection, plus auxiliary turn lanes. In 2004,
Timberline was classified as a 6-lane roadway north and south of the intersection
and interim improvements were constructed to a 4-lane interim roadway condition.
Since then, the city has downgraded the segment north of Prospect Road to be a 4-
lane arterial section while the segment to the south of the intersection remains a 6-
lane geometry. Therefore, it is the team’s goal to reevaluate the roadway geometry
as part of this next phase of construction.
Approach: Interwest recognizes that the new roadway classification to the north will render the previously
prepared “ultimate” plans virtually obsolete. In evaluating alternatives, the Interwest team will work closely with
city staff to develop a cost effective alternative design that meets as many of the prescribed city goals as is
practical. At the end of this section is Exhibit A with two potential design alternatives for consideration.
Option 1: This alternative reflects minor reductions in various aspects of the roadway geometry (lane and
median widths) in order to show that the city can achieve the desired lane configuration south of Prospect
Road with no widening of the existing Spring Creek Bridge. We would then propose that the city reuse
one of the two existing pedestrian bridges scheduled to be removed as part of the CDOT Mulberry Road /
Poudre River Bridge project for the required sidewalk on the west side of the existing roadway structure.
This alternative would result in significant cost reduction and time savings to the city as there would be
no FEMA or City Floodplain processes required. Park Planning and Development will be taking one of
the existing pedestrian bridges for a new trail crossing of the Poudre, but to our knowledge, there is no
use for the second bridge currently identified. The 165-foot bridge can completely span the existing
Spring Creek floodway and can be placed high enough to allow the Spring Creek Trail to still have
adequate headroom (more than the existing roadway bridge). The existing roadway bridge is a two span
structure with a center pier and any widening will require work and shoring within the channel. With the
pedestrian bridge solution, there will be no work in the channel, and no 404 permit would be required
from the Corps of Engineers. This solution reduces project costs, allows vehicular use of the bridge
during construction, utilizes an existing asset owned by the City, eliminates several lengthy approval
processes and is sensitive to the Spring Creek corridor. The monies saved with this option could be used
to enhance both bridges’ aesthetics and for additional urban design features and enhancements. Savings
could also potentially help fund a portion of improvements at the Riverside Drive intersection.
The City’s standard median width is nineteen feet to accommodate left turn lane pockets while
maintaining a minimum median nose of seven feet. However, from Blackbird to Prospect, there are no
full movement streets or high volume driveways. The enhanced medians that the City has been working
towards require less maintenance than those designed over the last 25 years, but are generally more
expensive to construct. Therefore, we would propose a continuous median width of twelve (12) feet as
shown on the Exhibit in order to still provide an enhanced landscaped section for the corridor. This
narrow median abuts a very large tree lawn on the east (built in 2005 in an attempt to preserve the
Johnson Farm trees), and the City’s substation which is heavily vegetated on the west. We feel there is
ample opportunity to beautify the corridor while saving seven feet of width throughout this roadway link.
SECTION 2 SCOPE OF WORK
Team Introduction3 of 15
Scope of Work
Timberline Road Corridor Improvements
RFP 7450
Option 2: This alternative reflects similar reductions to the median width south of the railroad; however,
it reflects no reductions in lane geometry or median nose width through the intersection. This option
requires that the Spring Creek Bridge be extended approximately 13 feet to the west, well short of the
previously anticipated 40 feet required with the previous 6-lane master plan geometry to the north. An
inherent benefit to both of these proposed alternatives is that the entire north side of the Prospect Road
intersection can maintain its current geometry. This would eliminate the need to further expand west into
the Bath Nursery property, and the existing full-turn movements at the Poudre School District Warehouse
building on the east could also be maintained if there are no changes to the north leg of the intersection.
It is still possible that a FEMA LOMR could be avoided with this alternative as Anderson Consulting
Group had previously modeled the bridge extension. However, at this time, we anticipate that a FEMA
process will be required with any work in the Spring Creek Floodway.
Please note that in the following discussions of scope, fee and responsibility, it is assumed that the project will not
widen the roadway north of Prospect or east of Timberline, and that the more traditional “Option 2” discussed
above will be designed. We feel that Option 1 is a viable alternative design, but it eliminates or changes many
design and coordination tasks described in the RFP. As a part of the project scoping, we will work with the City
to determine if Option 1 is a viable alternative to the City and we will adjust the scope as necessary.
SECTION 2 SCOPE OF WORK
Team Introduction5 of 15

RFP 7450
Existing Grain Silos:
Issue: There are five (5) existing grain silos located immediately adjacent to
Timberline Road at the southwest corner of the Prospect Road intersection.
Additionally, a single family house known to contain hazardous building materials
sits adjacent to the silos and is no longer used as a dwelling. These structures
were previously identified as being in conflict with the future ultimate roadway
widening. The city is seeking alternatives for relocating, repurposing or possibly
removing these structures which are all located on city owned property.
Approach: After inspecting the silos to determine their current condition and composition, the Interwest team
will provide the City with a structural analysis for deconstructing, removing and/or relocating the silos. Interwest
does not believe, however, that the house impedes the project in any way, and would suggest that it remain in
place. Leaving the house where it is provides a cost savings to the City, and an opportunity to add some visual
character and history to the intersection. Option 1 as described above and as shown on Exhibit A at the end of
this section shows that two of the existing silos and the grain elevator could in fact remain in place if the city so
desired. As with the house, this would be a project cost savings and retain some of the character of the area.
Spring Creek Bridge:
Issue: The existing bridge over Spring Creek was widened as part of the 2004
interim condition improvements. In order to provide a 6-lane geometry south of
the intersection, it is anticipated that the bridge will again need to be widened.
Approach: As noted above, the City has revised the classification of the section
of Timberline north of Prospect as a four-lane arterial. Therefore, the ultimate
width of Timberline south of Prospect no longer needs to be as wide as previously
planned. Interwest sees this change in future projections as an opportunity to
reevaluate the extent of the need to widen the bridge, and to propose an alternative solution to providing safe and
enjoyable bicycle and pedestrian travel through the intersection. Exhibit A describes a solution which we feel
addresses not only bicycle/pedestrian safety, but takes an approach which is sustainable and responsive to the
City’s environmental, social and economic needs.
Utility Conflicts:
Issue: There is an existing Xcel gas facility located on the west side of Timberline
Road and Xcel is looking to upgrade their current 8-inch lint to a 16-inch high
pressure gas line. During the interim design widening, a small retaining wall was
constructed to help protect the substation structure on the west, and the ultimate
roadway plans indicated that the entire structure would have to be relocated as part
of the widening.
Approach: By providing a narrowed 12-foot raised median, and with the new lane
geometry associated with the intersection, Exhibit A reflects the city’s ability to maintain the location of the
existing structure with either an attached or a detached sidewalk. By minimizing impacts to the substation the city
can save time and money related to the project as well as reducing potential impacts to the utility customers. The
team will also work closely with Xcel Energy to evaluate the aerial gas lines along the bridge to determine if an
alternative crossing design is warranted and will work closely with Xcel to integrate the new high pressure line
design.

Timberline Road Corridor Improvements
RFP 7450
Riverside to Timberline Congestion:
Issue: The segment of Prospect Road west of Timberline Road is not currently in the design or construction
budget of this project; however, this segment includes two difficult railroad crossings, heavy congestion due to
the close proximity of Riverside, heavy eastbound traffic turning right onto Timberline, and heavy north-bound
traffic on Timberline turning left onto Prospect then merging to the right in order to turn right onto Riverside. All
of these issues will be analyzed as part of the traffic analysis by Fox Tuttle.
Approach: The study by Fox Tuttle will address solutions for reducing traffic
delay and accidents through this segment. Interwest will also evaluate the vertical
profile of Prospect Road related to the railroad crossings to determine if there are
cost effective measures that could be implemented to improve the ride across these
tracks. We are hopeful that cost saving measures on the Timberline Road segment
will allow the city to implement improvements to this leg of the intersection sooner
rather than later.
Stormwater Quality
Issue: The interim roadway widening project did not include provisions for stormwater quality within the road
right of way. The majority of the original project was adjacent to developing parcels and those parcels were
required to provide stormwater quality and detention facilities for their half of the roadway. The ultimate
widening project is almost entirely adjacent to City owned property (on the west) or oversized right of way (on
the east).
Approach: Interwest will go back to the original drainage design from Blackbird to Prospect. We anticipate that
there is available area on City owned parcels to provide water quality facilities. If that is not the case, there will
be an opportunity to provide stormwater quality vault structures in key areas where the existing storm sewer
system will require reconstruction or retrofitting.

The following required elements of the project as outlined in the RFP will be achieved as part of the
Interwest Team Scope of Work:
Modeling of current traffic patterns and comparison to past projections
Modeling and recommendations for future traffic projections (including the Prospect and
Riverside intersection)
Improved air quality through reduced vehicle wait time
Improved safety for vehicles, bicycles and pedestrians; including the completion of the sidewalk
connection along the west side of Timberline (Prospect to Blackbird)
Design and construction of utility improvements including water quality features
Landscape and irrigation design for parkways and raised medians (by others – BHA Design)

Hydraulic modeling and review of past Map Revisions for the Spring Creek Floodplain
Design analysis for major turning movements
Design and construction of the project in a sustainable fashion which balances the environmental,
social and economic needs of the City and adjacent landowners
Project Approach
Over the last ten years, Interwest and our subconsultants have teamed on projects of all shapes and sizes, from
small intersections and widening projects to large multi-million dollar reconstruction jobs. We attribute our
success to a consistent approach to project design and management. The following methodology is tailored to
Timberline and Prospect, but is the same framework for success that we use on a regular basis.
First, the project scoping, contract negotiations, and kickoff meeting with the City and subconsultants will be
integral to the success of the project. We have outlined several critical issues above, but there are undoubtedly
additional issues that City staff are aware of that will need to be addressed in the preparation of the scope of
services.
The scoping meeting will give the team the roadmap for completion of the project. In the first three months of the
project, we expect to complete all data collection including the survey, utility locating and initial potholing,
property base maps, initial hydraulic study, environmental fieldwork, and geotechnical exploration, as well as the
first conceptual designs of the roadway and bridge. In this very early stage, we will work with the City to make
certain we are acceptably below the construction budget and will likely have multiple conceptual designs to
discuss. These initial designs are critical because at this point in the project, very little time is necessary for any
particular analysis, and design modifications are easy to incorporate.

instrumental in bringing all the parties together, when needed, to solve problems
and ensure everyone has the correct information.” (Harmony and Shields

The development of alternative designs with real-time cost estimating will be critical for
decision-making and building consensus regarding the nature of the improvements. Once
these initial steps are completed and the City is comfortable with the progress, the team
will assist the City in the first public open house. Plans will be in a very preliminary state
at this time, but with data collection and conceptual design options completed, we will be
able to conduct productive conversations with the neighbors and stakeholders. The
Interwest team will also support the City with one-on-one meetings with impacted
property owners. Again, at this early stage, it is likely that design adjustments will be
necessary based on the feedback from the public. As the design progresses, Interwest and
all of our subconsultants will work with the philosophy that the 30% design plan is not
30% correct; it is simply 30% complete.
Schedule
While the City is discussing the project with project stakeholders, Interwest will be working on advancing the
design, coordinating utility relocations, and overseeing the formal designs and required processes of the
subconsultants. The project will have many moving parts, but with proper coordination between the Team and
the City, we are confident that the project will be able to move toward preliminary plans late in the spring of
2013.
To achieve comfortably the project’s design and construction schedule, it will be necessary to formalize the limits
of right of way and easements in the summer of 2013. The team will implement a series of real time design and
review meetings with city staff to foster a working collaboration process, make efficient use of team member’s
time, and minimize potential re-work based on offline review periods.
Specific Consultant Tasks
Following is a detailed explanation of each key team member’s responsibility on
this project. Generally, the tasks are presented in the order the design will follow.
The final scope for each team member will be determined during contract
negotiations with the City. We have assembled a complete team based on our
understanding of your needs. If there are tasks that are to be performed by the City,
or otherwise determined to be unnecessary, they will not be included in the final
contract. Each team member firm has sufficient qualified personnel to provide any
supplemental support necessary to complete the project.

Data Gathering
Topographic and Property Survey
The City will provide all survey services and provide the data to Interwest for the preparation of the base
mapping. Interwest will complete a Survey Request Form detailing the limits and purpose of the survey items
needed, including channel cross sections if they are determined to be required for hydraulic modeling.
Soils Investigation and Structure Foundation Report:
CTL Thompson (CTL) will perform a geotechnical investigation along the roadway corridor, on Timberline Road
south of Prospect, and to the west of the Spring Creek Bridge in coordination with the structural engineers. It is
anticipated that six (6) borings will be conducted along Timberline Road and another two (2) on the west side at
Spring Creek for structural design purposes. CTL will prepare a design report with pavement section options and
recommendations, as well as the necessary data for the design of all structures. All geotechnical design will be in
accordance with City Standards.
Utility Potholes:
During the previous project in 2004, the team procured hundreds of utility potholes
along the corridor and we anticipate utilizing the majority of these previous
locations. However, due to the revised geometry and potential utility
improvements over the past eight years, we anticipate the need for a minimal
number of additional potholes. After the initial conceptual design is complete, and
likely utility conflicts are identified, Interwest will prepare a pothole map for
approval by the City. Once all parties are in agreement with the scope of the
pothole operation, the proposed locations will potholed by Colorado Utility
Finders. After completion we will coordinate with the City Survey Department to locate the potholes
horizontally and vertically for design purposes. This method of potholing is extremely effective and allows us to
design our projects with the existing utilities as a “known” rather than “unknown” factor.
Utility Coordination:
Interwest will lead the utility coordination effort, working closely with the utility providers to ensure the accuracy
of the utility mapping process and to develop thorough utility relocations plans as needed. Interwest will provide
all drainage designs, including the preparation of required calculations and reports for water quality and adequate
storm drainage outfalls.
Environmental Study and Clearances:
Cedar Creek Associates will provide all of the work related to environmental services for the project. The
following tasks are based on a design that requires the city to widen the existing Spring Creek Bridge. If Option 1
were to be implemented as described above, it is anticipated that there would be no need to map the wetlands or
provide habitat surveys.
Wetland mapping will be completed using the methodology outlined in the publication Corps of Engineers
Wetlands Delineation Manual (1987) supplemented by the document Interim Regional Supplement to the Corps
of Engineers Wetland Delineation Manual: Great Plains Region. Intensity of mapping will conform to the
"routine, on-site determination method". Wetland boundaries and sample point locations will be marked in the
field and drawn on a field map for identification purposes. The engineering firm will cause to have a survey
completed and a delineation map prepared for submittal to the Corps of Engineers. Cedar Creek will prepare a
letter report for submittal to the City of Fort Collins and the Corps of Engineers detailing the methodology used to
survey the site and the results of the fieldwork. Copies of all field data sheets and the delineation map will be
included with the letter report. The delineation will be completed in the spring of 2013. It assumed at this time

that any bridge work will span Spring Creek wetlands and a Nationwide Permit from the Corps of Engineers will
not be required.
Habitat evaluation surveys for the Preble’s meadow jumping mouse will be completed in conjunction with the
wetland delineation in accordance with U.S. Fish and Wildlife Service guidelines. It is assumed that trapping will
not be required for this project. A Preble’s meadow jumping mouse habitat evaluation report for the site will be
submitted to the U. S. Fish and Wildlife Service to obtain concurrence with the findings of lack of suitable
habitat.
Traffic Impact Analysis:
The Fox Tuttle Transportation Group will provide transportation engineering and
planning services for this project, to include Traffic Modeling, Analyses, and
Report, including Multi-Modal transportation assessments and recommendations.
Fox Tuttle will also provide traffic signal design for modifications at the Prospect
& Timberline traffic signal, to accommodate additional through lanes in each
direction, an eastbound-to-southbound right-turn acceleration lane (and thus, free-
right movement), and any other geometric modifications. Traffic signal plans will
be prepared per LCUASS, AASHTO, and MUTCD standards and guidelines.
Preliminary Engineering Phase – 30% Plans
Roadway Design Plans:
Interwest Consulting Group will be responsible for the roadway design of the project from start to finish. The
design will include alignment, typical sections, profiles, grading, structure layout, construction phasing plans and
cross sections as the base scope. Interwest will also be responsible for coordinating utility relocations, lowerings
and abandonments as well as any modifications to irrigation facilities in the area. All of the items specified in the
RFP will be included in the plans and submittals, and Interwest will coordinate all of the design and
documentation requirements of the team prior to releasing information for review to the City. We will prepare a
complete design that is easily reviewable and conveys the exact intent of the designer to the contractor and
construction inspector. As the lead consultant, Interwest will take full responsibility for quality control means and
methods and will not rely on the city to perform quality control reviews of the construction documents.
Public Outreach / Streetscape and Acquisition Mitigation:
BHA Design, Inc. will lead most of these services through their on-call contract. Interwest has a long-standing
working relationship with BHA on many public and private development projects over the past 12 years. We will
work closely together in the development of the identity for the corridor. We recognize that this is a high profile
project with high visibility from the City Manager’s Office and we will work closely with BHA and City staff to
develop a project worthy of a world class city.
“The Town of Windsor and I were pleased with the final design and product they
provided, and would recommend the firm of Interwest Consulting Group to other
agencies requiring similar engineering design services.”

SECTION 2 SCOPE OF WORK
Team Introduction11 of 15
Scope of Work
Timberline Road Corridor Improvements
RFP 7450
Interwest and BHA will prepare site specific Mitigation Plans for adjacent property owners to accurately reflect
any proposed impacts and the mitigation measures proposed. At this time it would appear that there are only two
non-city owned properties that will be impacted by the design, these being Timberline Star and the parcel at the
southwest corner owned by Mr. Keating. However, the RFP indicated the need to provide Mitigation Plans for
four (4) affected parcels and the fee estimate reflects that request.
Local Drainage Design and Water Quality:
Interwest will provide the roadway drainage design for the project. The challenge
here will not just be the collection of the storm water in gutters, inlets and pipes,
but more likely will be providing manageable water quality facilities. During our
initial work on this project, we are proposing that a water quality pond be
constructed where it can be conveniently maintained and where all of the storm
water on the west reaches of the roadway can easily be easily conveyed. Interwest
will prepare a detailed Drainage and Erosion Control Report that will reflect
required hydrologic, hydraulic and erosion control measure calculations.
Public Utilities Commission Permitting:
Wilson and Company (Wilson) will prepare an application to the Colorado Public Utilities Commission for
improvements to one (1) at-grade rail for the project (on Timberline Road). The application will be prepared
pursuant to the Commission’s “Rules Regulating Railroads, Fixed Guideways, Transportation by Rail, and Rail
Crossings”. An exhibit will be prepared as required by the Rules in support of the application.
Wilson will coordinate and execute a field diagnostic meeting for the crossing,
obtaining attendance at a minimum from the Colorado Public Utilities
Commission, the Railroad (GWRR), the City of Fort Collins, and Wilson. The
meeting will review existing conditions at the crossing and confirm
recommendations for improvements to the grade crossing devices and railroad
signals. It is assumed that the Great Western Railroad will prepare plans for the
grade crossing improvements and signals. Wilson will coordinate obtaining cost
estimates for improvements to be constructed by the railroad, to support the City
with project budgeting and agreements with the railroad.
Specifications and Estimates:
It is critical that the City be presented with a set of construction documents that can be successfully bid and built.
Interwest will be responsible for the preparation of Specifications as well as cost estimates and recommended
construction phasing diagrams for the project.
Floodplain Modeling and FEMA Processes
Anderson Consulting Engineers (Anderson) will provide hydraulic modeling associated with the widening of the
Spring Creek Bridge. It is important to note that should the city pursue Option 1, which shows no additional
widening of the bridge, there would be no requirement to submit a LOMR application since Anderson has
previously modeled the interim condition bridge. This would have significant cost and time savings for the
project.
SECTION 2 SCOPE OF WORK
Team Introduction12 of 15
Scope of Work
Timberline Road Corridor Improvements
RFP 7450
In the event that the bridge is widened, Anderson would provide the required analysis, modeling and design of
erosion countermeasures. These tasks would include the preparation of a Floodplain Use Permit and a LOMR
application to FEMA along with all required supplemental documentation. Based on the results of the ultimate
condition analysis in support of the previous CLOMR which showed no-rise in the 100-year water surface
elevations, it is assumed that a no-rise will be achieved with the as-built conditions, resulting in no adverse flood
impacts to adjacent property owners.
Structural Design – Spring Creek Bridge:
Loris and Associates (LORIS) will perform all structural analyses and prepare
construction documents for the widened Spring Creek Bridge. Having prepared
the previous bridge widening design plans in 2005, LORIS has a unique
understanding of the bridge structure. Their structure selection analysis was used to
establish the structural guidelines which will now be used for the next widening
project. Loris will be involved in all phases of the project as follows:
1. Project Scoping and Conceptual Design (Kick-off Phase)
a. Scoping Meeting – meet with The City of Fort Collins and Interwest to discuss the project and
refine the scope of services to reflect exactly what the city wants and needs.
b. Pre-design meeting – LORIS will attend a pre-design meeting to discuss their role in the project.
The City and Interwest will inform Loris of any special design requirements.
c. Geotechnical Engineering – LORIS will provide geotechnical investigation and recommendation
requirements to the team’s consultant, CTL Thompson, as they pertain to the bridge.
d. Bridge Construction Phasing Plan – Develop a phasing concept that keeps two lanes of traffic
open in each direction with turn lanes, as necessary, during construction. Bridge phasing plans
will be prepared and submitted.
e. Public Process – Attend two Public Meetings. Modify proposed bridge drawings to be used as
exhibits.
f. Conceptual Design Review Meeting – Attend one meeting in Fort Collins.
2. Preliminary Design (30%) Incorporate Conceptual Design Review and public comments and advance the
design.
a. Bridge Design – Provide bridge foundation and superstructure design. All design and drawings
will be performed according to CDOT requirements.

This intersection was a CDOT Local Agency Project with Federal Safety Money
and CDOT oversight for the City of Greeley. This project consisted of adding a
traffic signal to the intersection as well as providing left turn lanes in both
directions on 37th Street (Weld County Road 54) in order to improve safety for
cross street traffic. Notice to Proceed with the design on this project was given on
April 1, 2010, and construction was completed in the fall of 2010. This aggressive
schedule was achieved due to Interwest’s creative approach to meeting critical
dates, and commitment to meet those dates. Interwest prepared a design schedule
that required all background information to be obtained in the first two weeks of the project, had an informal
meeting with the City, County and CDOT the following week, and had completed drawings for CDOT’s
FIR/FOR review on June 4, 2010. The FOR Meeting was held three weeks later and all revisions were made
giving the project clearance for bidding on July 1.

Taft Hill Bridge over Poudre River – Fort Collins
(Loris)
This $2.5 million bridge replacement consisted of the construction of 1,500 feet of
roadway and a two-span, 242-foot long pre-stressed girder bridge. Alternate
roadway alignments were investigated by Loris and Associates to relocate the
bridge and keep the roadway open during construction; however, the constricted
geometry and complex hydraulic requirements on the Cache La Poudre River
dictated that the bridge remain in its existing position. A shoofly detour was
constructed to reroute traffic during construction. The bridge, constructed with
concrete caissons and BT63 girders, had a steep skew that required special
detailing

Matterhorn Bridge Replacement - Vail, CO (Federally Funded, CDOT Region 3)
(Loris)
LORIS is currently serving as Prime Consultant on this project to replace the
Matterhorn Circle Bridge over Gore Creek. This previously existing bridge
which was a main thoroughfare for a multitude of utilities was in critical
condition due to scour damage at the abutments. Extreme channel flow
velocities and a bend in the channel alignment at the bridge location dictated a
longer bridge span supported on deep foundations. Tight physical constraints
associated with an adjacent intersection, utilities and adjacent properties,
compounded by difficult subsurface conditions, limited the bridge options.
Located in a residential area, aesthetics and environmental sensitivity were key considerations.
The replacement bridge consists of a pre-stressed box beam superstructure on wall type abutments with
multiple rows of piles. It is approximately 15’ longer than the previous with heavy channel armament for scour
protection. A variable width deck is incorporated to accommodate a portion of the adjacent T-intersection
geometry, and a multitude of relocated utilities reside between the girders. A modified aesthetic Michigan DOT
bridge rail with custom end pilasters and formliners were incorporated for aesthetics.
