The firm designed improvements to East 66th Street South between Mingo
Road and 101st East Avenue. The finished road will be two lane asphaltic
concrete with curb and gutter. The storm piping system will tie to new
storm structures on Mingo Road.
We are responsible for design survey, pavement section design, drainage
analysis, geometry, earthwork, etc. Plans and specifications are being
produced meeting all Tulsa requirements.
Other work includes utility relocation and temporary easement preparation.
During the bidding and construction phases, will provide bidding assistance,
recommendation of award, construction staking, submittal review, pay request
review, periodic and final inspection and as-built drawings.
Project List
The purpose of this project was to remove an existing overpass and construct
an at-grade railroad crossing. Prior to design, the railroad company abandoned
the line. Primary emphasis shifted to removal of the bridge and approach
embankments.
The conceptual report compared the alternates of replacing the existing
overpass with a new bridge versus making an at-grade crossing. The at-grade
crossing was chosen but later became unnecessary.
The project was designed in-house. Topography was mapped by aerial photography.
Geotechnical investigation was done by a local firm.
The design considered tie-ins to driveways on Mohawk Boulevard and one
intersection. Due to the approach embankments, there was excess fill material.
A nearby stockpile location was identified so that the material (about
25,000 cubic yards) could be used on another project. This design was
closely coordinated with the design of the Gilcrease Expressway, which
had an off-ramp planned for the east end of the Mohawk improvements.
Other significant items of work included storm drainage, water line relocation,
erosion control plan, Stormwater Pollution Prevention Plan, and construction
cost estimate.
Project List
The firm prepared contract documents, plans and specifications for maintenance
work on city non-arterial streets. Type of construction work included
crack sealing, partial and full depth patching, micro paving, overlays,
curb replacement, utility adjustment, storm sewer modification, and street
reconstruction.
The project was located in part of Northwest Tulsa covering approximately
6 square miles of residential area.
Inspection teams performed field evaluations of streets which were identified
by the "PAVER" pavement management system as in need of rehabilitation
work. The engineers made recommendations on the actual work to be done
and prepared the necessary plan documents. Some field surveys were done
with in-house crews where major reconstruction was planned. Repairs were
quantified for estimation and bidding.
Plans were developed using AutoCAD software. The project included about
250 lane miles of pavement. The work was put out for bids in six separate
bidding packages.
The firm assisted in the bidding process and provided the bid tabulation.
Project List
The firm designed widening and improvements to Adams Road from 2nd Street
to 10th Street , a distance of 3,540 linear feet. The work was divided
into preliminary and final design phases and services during construction.
The design phase included a detailed hydraulic and hydrology investigation
to determine the storm sewer requirements. Hydraulic analysis included
investigations to show the effects of downstream water discharge points.
The existing two lane road with bar ditches was improved to four lanes
with curb and gutter.
The firm developed the design profile and pavement section. Much of the
design calculations were done using the "Softdesk" software.
The most recent version which runs in AutoCAD was used. Intersection details
and joint layouts were done. A construction sequence plan was made showing
traffic control and detours.
A portion of the project, including the intersection at tenth street and
Adams Road was presented on the plans as an "add alternate"
which would be built subject to the availability of funds.
The company's other duties included public meetings, right-of-way plans
and cost estimates. We were involved with recommending utility relocation
and coordinating work with the public and private utility companies.
Services during construction included assistance during bidding, bid tabulation
and recommendation, prebid and preconstruction conferences, shop drawing
review, pay estimate review, periodic inspection, final inspection and
as-built drawings.
We also performed the surveying tasks related to completing the design.
Section line established our construction line (CRL) from beginning to
end of project. Additionally, Broadway intersection details 500 feet in
either direction along Broadway is considered for connecting surveys.
Design is also considered 500 feet in each direction from the centerline
of 10th and Adams for which each section line has been determined.
Bench levels through 8 aerial targets were performed and the coordinate
and elevation values were given to Aerial Data Service as the controlling
factors to generate accurate contours and topography of the project length.
All the utilities affecting the design of the project were field located
and incorporated into the digital terrain model provided by Aerial Data
Service in AutoCAD format. Our design software was then utilized to cut
cross sections and compute quantities and other related design tasks.
Project List
The firm was retained by the City of Tulsa to design and prepare detailed
plans and specifications for the widening and improvement of the major
arterial intersection within the city limits. New geometry included medians
for left turn lanes.
All survey work was done in-house and included location of above and below
grade utilities and obstructions, section line survey, topographic survey
and construction staking. Cross sections were taken at every 25 feet.
We coordinated a comprehensive testing program to establish the suitability
of the existing pavement to act as a base for an asphalt overlay and to
determine soil conditions for design of new pavement.
The firm devised a construction phasing schedule and detours to allow
use of the intersection during construction. We also researched existing
right-of-way and recommended additional right-of-way where required. Right-of-way
acquisition maps were prepared and locations were field staked.
The existing storm drainage system was inadequate, therefore, a complete
new system was designed. Peak flows from a 40 acre drainage area were
calculated using the Rational Method for 100- year storms. City of Tulsa
design criteria was followed to size inlets and pipes. City approved design
charts for grate capacity were utilized. The final system included storm
piping sized from 15" to 48" in diameter and a 60" culvert.
An improved drainage channel was designed and permanent drainage easement
prepared.
Other services included detailed cost estimates, relocation of a water
line and assistance during bidding. Work during the construction phase
included periodic inspection, shop drawing review, pay estimate review,
final inspection and as-built drawings. In addition, resident inspection
was provided under this project.

Railroad Spurs & Access Road to Wellington Industries -- Sand Springs,
OK
The project included an extension of South Main Street and two railroad
spurs to serve a new manufacturing facility.
The road had a 32-foot wide asphalt section with aggregate base and geotextile
fabric. There was one culvert and an at-grade railroad crossing. Total
length was about 1,160 feet. The firm's project engineer did all geometry
and drainage calculations.
The spurs were switched off of an existing track and were about 1,400
feet in total length. The ballast was supported on geotextile fabric.
One of the rails entered into the manufacturing building and the other
paralleled an existing loading dock.
All surveying was done by in-house field crews using total station equipment.
The soils conditions were studied carefully. The soil was very sandy and
contained construction debris in some areas.
The firm handled the bidding procedure, tabulated the bids and made a
contract award recommendation.
Services during construction included the prework conference, approval
of submittals and pay requests, change orders, periodic and final inspections
and as-built drawings.
Project List
The firm was retained as section engineer and was responsible for complete
final design services for 5.1 miles of the Cherokee Turnpike. Included
in the project was the design of the four lane turnpike, interchange ramps,
six bridges and local crossing and access roadways.
Services provided by our firm included surveys, analysis of alignment
and bridge alternatives, preparation of plans and specifications for grading,
paving, drainage, bridges, retaining walls, box culverts and utility relocations,
right-of-way acquisition and construction staking.
The six bridges included two main line bridges and four county bridges
ranging from 2 to 4 spans using prestressed concrete beams. Also included
were eighty-eight culverts, including pipes, ranging from 18" to
48" in diameter and boxes up to triple 10' x 8' in size. Special
designs were used for several of the box culverts.
Due to terrain and geotechnical problems, special consideration was given
to roadway drainage. Hydraulic calculations were conducted using HY-8
software to size the roadway ditches and culverts. In lieu of ditches,
where grades were excessively steep, piping was required to carry water
from the roadway to the existing drainage channels.
Aerial topography for the route was provided by the turnpike authority;
however, on-site supplemental field data was needed at critical locations,
such as roadway intersections, drainage structures and underground utilities.
Breisch & Associates performed the supplemental work and staked the
centerline and right-of-way.
The design period for completing the work was much less than would normally
be allowed. Therefore, the contract included penalty and bonus clauses
for completing the work. The company was successful in earning a bonus
by finishing its work ahead of time.
We also performed construction surveying and layouts for twenty-five miles
of Cherokee Turnpike along Highway 33 near Locust Grove, Oklahoma.
The scope of work included original and final cross sections, permanent
and temporary right-of-way staking, horizontal and vertical control, centerline
staking, slope stakes at 100' intervals, staking of all drainage structures,
staking of bridges (including a double bridge across Highway 82), blue
tops and as-built cross sections.
Project List
Garnett Road is an arterial street with twelve residential side street
intersections. Two major stream crossings are involved in this project.
The scope of the project was to reconstruct Garnett Road from 31st Street
to 41st Street from a two lane road with bar ditches to a five lane facility
with curb and gutter, including six foot sidewalks.
The firm's scope of services included a preliminary report phase, preliminary
design and final design. The preliminary report phase considered different
layouts such as four lanes, five lanes and the addition of bicycle lanes.
The firm coordinated the aerial photography and the geotechnical investigations.
One of the stream crossings required a new multiple barrel box culvert.
A new storm drainage system was designed to replace the existing bar ditch
system. Plan and profiles were developed, typical sections were designed,
rerouting of water and sanitary sewer systems were coordinated, construction
sequence plans were made and the firm participated in public meetings.
The design included numerous intersections into residential neighborhoods.
All design surveying was also provided by our firm. The work included
establishing state plane coordinates for the site along with VSC46S elevations.
A complete right-of-way and section survey was performed along the route.
Hydraulic surveys were performed along 2 creeks, 500' up and down stream.
Connection surveys were performed along several intersections along with
the standard profiles and cross-sections. All utilities, drives, fences
above and below ground were located.
Project List
The firm was retained to provide plans and specifications for various
improvements along and adjacent to Lewis Avenue from 3rd Street to 11th
Street. The repair included milling approximately 6 inches of asphalt
off an existing concrete base and overlaying the existing base with 2
inches of asphalt. Areas of subbase failure were removed and patched prior
to the overlay placements.
The streetscaping portion of the project is included in the City of Tulsa's
trail system and consisted of replacing the existing curb and sidewalk
on the east side of the street. The new sidewalk was 15 feet wide and
included trees, benches, period style street lamps and brick paver patterned
concrete.
As a part of the project, three streets in adjacent residential areas
were closed by construction of cul-de-sacs.
The firm's project engineer coordinated the geotechnical investigation.
Utility relocations were recommended and designed. The plans included
changes in the storm sewer system and water distribution lines. Cost estimates
were provided at each phase of the design.
Services during construction included assistance during bidding, bid tabulation
and recommendation, pre-bid and preconstruction conferences, shop drawing
review, pay estimate review, periodic inspection, final inspection, as-built
drawings and construction staking.
Project List
The firm designed a pedestrian/bicycle path across the Arkansas River
bridge from Riverside to Elwood Avenue as part of the Tulsa trail system.
The river crossing was done by building the path on the existing extended
pier caps along the north side of the highway bridge and railroad overpass.
As part of the conceptual design, five alternate designs for the bridge
portion of the path were considered.
The 10-foot wide path was asphalt on grade and reinforced concrete at
the bridges. We were responsible for the structural design, fencing and
lighting as well as the normal civil aspects of the project.
The structural design included analyzing the existing pier caps to ensure
they could support the trail lighting fixtures on pier cap brackets. We
also designed the safety rail system to withstand the weight of a crowd
leaning on the rails. Lighting was placed on 40-foot masts and served
to light the north half of the street as well as the pedestrian/bicycle
path. The portion of the existing path which crossed under the east end
of the Arkansas River Bridge was lowered to provide adequate head room
for bicyclists.
We assisted in the bidding phase and provided general construction services
including preconstruction conference, shop drawing review, approval of
pay request, periodic inspection, final inspection and record drawings.

West 41st Street (S. 57th W. Ave. to 41st W. Ave. – Tulsa County,
OK
The project was to widen West 41st Street from 57th West Avenue to 41st
West Avenue from a two lane road with bar ditches to a four lane arterial
street with curb and gutter in some locations, including reconstruction
of a major intersection at 49th W. Ave., as well as residential street
intersections.
West 41st Street serves numerous commercial and residential properties
which required the reconstruction of approximately forty-five driveways
to meet existing grades.
The design included detailed hydraulic and hydrology calculations to determine
drainage requirements and the effect of down stream discharges, utility
relocation, design profiles, pavement sections, intersection details,
construction sequence plans, coordinating utility relocation, design surveys,
cost estimates and coordination of geotechnical services. We were also
responsible for services during construction.
The firm also described all right-of-way takes for the County.
