`Slipforming Success with the New GOMACO GP3 Concrete Paver
`

`
`The new GP3 has been used on projects all around the world, including Pittsburgh, Pennsylvania, where Swank Construction is reconstructing fi ve miles (8 km) of Interstate 376 eastbound and westbound lanes.
` GOMACO Corporation introduced the new GP3 slipform
`paver for widths up to 30 feet (9.14 m) at World of Concrete
`in Las Vegas, Nevada, and then to the international market
`at Bauma in Munich, Germany, earlier this year. The dual-
`telescoping GP3 is the fi rst in a new family of the world’s
`most intelligent pavers. It features Smart Frame Widening to
`accommodate multiple width changes, Smart Leg Positioning
`
`and Smart Steering with full-steer tracks, all
`controlled by the GOMACO-exclusive G+®
`digital control system.
`
`The new GOMACO GP3 slipform paver
`has been designed to easily accommodate
`multiple width changes. It features a roller
`frame with dual-telescoping capabilities
`of up to seven feet (2.13 m) on each side
`of the paver, for a total of 14 feet (4.26 m)
`of automatic frame widening. Hydraulic
`
`telescoping frame members in the front
`and rear of the mainframe allow the dual
`telescoping capability. The GP3’s dual-
`telescoping frame is the fi rst in the industry
`to incorporate Smart Cylinders. The Smart
`Cylinders provide the width reference to the
`G+ controller and uses that information for
`steering setup and individual track speed
`control through radii. Automatic camber is
`built into the frame as it extends with the
`

`

`

`unique GOMACO roller frame. The T-beam
`mounting rail is incorporated into the
`telescoping frame.
`
`The GP3’s Smart Leg Positioning
`includes rotary sensored slew drives on
`the pivot arms of each of the paver’s four
`legs. The Smart Pivots on the legs provide
`the G+ control system with information
`on the angle of rotation and work
`together with the track rotation sensors
`to maintain the tracks in the straight-
`ahead steering line. Rotary sensored
`slew drives are also located on each of
`the paver’s four tracks for the ultimate in
`Smart Steering technology and extreme
`steering with the tracks having the ability
`to steer farther than ever before. The
`Smart Track Rotation provides the G+
`control system with exact track location
`and position. The GP3 easily turns radii
`with Smart Leg Positioning and Smart
`Track Rotation. They work with the G+
`control system to automatically control
`the direction and speed of the track travel
`through a radius.
`
`The new paver has been designed
`for easy transport. The paver is put into
`the Transport Mode by simply driving the
`legs around to the transport position with
`the GP3’s tracks and hydraulic rotational
`sensored pivot arms. With the legs in the
`transport position, G+ travel is switched
`to “Transport” for complete control. The
`GP3 has a retractable, sliding operator’s
`console to reduce the shipping width of
`the machine. The paver has
`a minimum transport width of only
`8.51 feet (2.59 m) and 33.3 feet (10.15 m)
`minimum transport length.
`
`The GP3 was designed to be easy
`to operate with the G+ control system,
`as well as comfortable for the operator
`while off ering a complete view of
`the entire job site. Vibrator modules
`are positioned across the front of the
`operator’s platform for easy accessibility

`
`Each leg has 42 in. (1067 mm) hydraulic height

`

`Swank Construction Company has a long-time roadbuilding history, and they chose the GOMACO GP3 with Trimble 3D guidance for their mainline paving projects around the Pittsburgh area of Pennsylvania.
`
`Swank Construction Company
`
`New Kensington, Pennsylvania
`
`Swank Construction Company has a long and prestigious
`
`history in and around the Pittsburgh, Pennsylvania, area. They
`are a fourth generation family-owned construction company
`that traces their roots back to approximately 1930.
`
`“No one knows exactly when we started, but we’re pretty
`sure around 1930 my great-grandfather started business with
`a mule and a wagon full of bricks,” Andrew Swank, an owner
`of Swank Construction, explained. “Most of our time has been
`as a concrete road and bridge constructor, so through the
`history of American roadbuilding, we’ve been there.”
`
`It wasn’t until recently though, that the
`
`company decided to get into the concrete
`slipform paving market. They meticulously
`did their research on concrete slipform
`pavers and their diff erent features. They
`knew they wanted a 3D machine guidance
`system with it and the paver needed to be
`versatile, easy to transport, and able to work
`in tight-clearance conditions.
`
`After comparing the various pavers and
`each of their attributes, Swank Construction
`ultimately narrowed down their search to
`the new GOMACO GP3.
`
`“Travis Brockman, our GOMACO district
`representative, and the whole GOMACO
`group were amazing and just blew
`everybody away, to be honest,” Swank said.
`“They talked a big game in the sales pitch,
`which all salesmen do, but Travis has backed
`it up and so has the rest of his team. They’ve
`
`been out here since day one helping us,
`getting us familiar with the machine. It’s
`been fantastic so far.”
`
`Swank Construction’s GP3 was delivered
`right to the project at the intersection of
`Interstate 376 and the McClaren Road, Exit 4,
`in Pittsburgh. Swank is reconstructing fi ve
`miles (8 km) of both the eastbound and
`westbound lanes of the interstate, which
`is the main access road to Pittsburgh
`International Airport.
`
`The new three-lane roadway will
`be completed in diff erent paving widths
`ranging from a 15 foot (4.6 m) wide
`shoulder, to a 22 foot (6.7 m) wide pass
`which includes a 12 foot (3.7 m) driving lane
`with 10 foot (3 m) shoulder. The company
`has also purchased an IDBI attachment
`to insert transverse joint bars in the new
`pavement on-the-go. The GP3 with IDBI will

`
`One of the big problems with this project is it’s so broken up and all over the place,” Douglas said. “We have
`actually spun the paver, walked it up on a lowboy with the mold under it, moved it, and poured the same day

`
`Trimble’s PCS900 paving control
`system uses total stations, sensors on the
`paver, and their software to guide the GP3.
`The 3D model of the construction site is
`prepared using their Business Center - HCE
`software. It has a virtual “drive through”
`feature allowing contractors to address
`any potential issues with the model before
`concrete paving begins. Swank uses
`three to four total stations to control the
`alignment of the paver during slipforming
`with precise millimeter control of the
`mold. When its time to switch from one
`total station to the next, the system will
`automatically and instantly transition to
`the next total station. The feature is called a
`“hot swap” and there’s no need to stop the
`paver. The same tolerance between total

`
`G+ Ground Control is available on the GP3. It’s a
`remote operator’s screen that can be positioned
`anywhere on the paver and allows the ground
`crew to see the same image that’s on the G+
`controls at the operator’s station. The crew can
`monitor their GSI readings, Trimble information
`and G+ operating status. Ground control also
`allows the ground crew to fi ne tune the paver and
`make adjustments to the settings.
`
`The GSI smoothness readings can be viewed on the
`GSI display (right monitor), as well as on the new
`G+ Ground Control display screen (left monitor).

`
`“We’ve been trying to keep total
`station distance around 300 feet (91.4 m),
`but we have a lot of light poles along
`here and they become a giant obstacle
`when you start setting the guns up,”
`Douglas said. “More often then not, we fi nd
`ourselves putting the guns a lot closer just
`because of obstacles. Our surveyor stays
`busy just because we don’t have the luxury
`of open real estate beside us. It’s a rehab,
`not a new job.”
`
`PennDOT uses the International
`Roughness Index (IRI) as their standard
`for pavement rideability. The specifi cation
`requires an IRI of 70 or below. Anything
`over 70 requires corrective action. The
`GP3 is equipped with mold-mounted GSI®
`(GOMACO Smoothness Indicator) units
`constantly measuring and reporting the
`smoothness of the new pavement.
`
`“We were in the 30s last week,”
`
`Patent Owner, Guntert & Zimmerman - Ex. 2045, p. 7
`
`

`

`Douglas said. “We’re milling subgrade with
`the Trimble system on our model and we’re
`seeing each layer come back fl at and nice
`and it’s coming back in the ride. I’ve only
`worked around stringline before, so it’s all
`new to me. I am extremely impressed.”
`
`Swank can monitor their GSI readings,
`along with Trimble 3D and G+ information
`all from ground displays located within
`eye level of personnel. The G+ features a
`remote operator’s screen with the same
`graphical display as the operator’s station.
`It’s called G+ Ground Control and allows
`ground personnel to see everything on the
`screen that the operator does on top of
`the paver. Ground Control also gives them
`the ability to fi ne tune the paver and make
`settings adjustments.
`
`“Typically we have the three boxes on
`the side of the paver,” Douglas explained.
`“We have the box that’s basically the
`refl ected image of what the operator sees,
`
`which we have some control on that. Then,
`we have the Trimble box which is all run
`from the ground, trading guns on and off ,
`and then we have the GSI box for the ride
`spec.”
`
`Portions of the 15 foot (4.6 m)
`wide shoulder with four percent cross
`slope are scabbed onto the existing
`two lane roadway. Even for the scab-on
`work, Swank Construction is remaining
`stringless. G+ controls allows them the
`added versatility with various sensoring
`capabilities.
`
`“We’re running grade and steering off
`the existing slab and running cross slope
`with the paver locking the other two legs,”
`Douglas explained. “We’re actually running
`off sensors, no stringline. We have a sensor
`on the slab and then we took a steel plate,
`bolted it to the back leg, and that runs our
`back grade and the back steering.”
`
`A GOMACO T/C-600 texture/cure
`
`machine follows the GP3 applying a
`longitudinal tine and white spray cure.
`Wheels attached to the sensors on the
`texture/cure machine allow steering to be
`referenced off the side of the new slab and
`grade control to be referenced off the top
`for this stringless project.
`
`The new concrete slipformers are
`quickly becoming experienced veterans
`as they continue the shoulder work on the
`project and progress to the driving lanes
`and eventually outfi t their GP3 with the
`IDBI attachment. The GP3 and its versatility
`has proven itself already in the tight
`project conditions. It’s transportability has
`also been a major factor. Even though it
`hasn’t moved off the interstate, it’s been
`loaded up and moved several times along
`the length of the project.
`
`“One of the big problems with this
`project is it’s so broken up and all over
`the place,” Douglas said. “We have actually
`
`spun the paver, walked it up on a lowboy
`with the mold under it, moved it, and
`poured the same day with it because
`there’s really no set up. Spin it, set it, set
`your guns, and away you go.”
`
`Swank Construction’s GP3 paver is the
`third one manufactured by GOMACO, with
`serial number 912600-003. Sometimes, the
`company has hesitated in the past with
`buying a new model.
`
`“I have hesitated before buying the
`newest model of something, but didn’t
`really hesitate here except maybe in the
`back of my mind and thinking I hope this
`thing works fi ne just like the rest of the
`GOMACO fl eet,” Swank said. “If they’re
`selling you, they’re being honest with
`you. They do follow through. They’re
`not blowing smoke. It’s been great and
`we’re probably still rookies, but we’re fast
`turning into experienced pavers now.
`We’re getting down the road.”

`Charles Vrana & Son
`Construction Company
`Omaha, Nebraska
`Charles Vrana and Son Construction Company, based out of
`
`Omaha, Nebraska, have been actively building a variety of construction
`projects large and small since 1909. They’re a family-held business
`and one of their specialties is civil and heavy highway construction.
`They have owned several GOMACO 9500 trimmer/placers through
`the years and they are now the proud owners of a GOMACO GP3. It’s
`the fi rst GOMACO concrete slipform paver in their extensive fl eet of
`roadbuilding equipment.
`
`Don Sell, Equipment Manager for Vrana, was very involved with
`the ordering of the new paver, specifying the mold, and other paving
`attachments. The list of requirements included a telescoping mold, a
`front bar inserter, and a machine that could be easily transported with
`the paving mold still attached.
`
`“We went with the GP3 with a 5400
`
`series mold spec’d out to 26 feet (7.9 m)
`wide,” Sell said. “The mold has telescoping
`end sections in it because we do a lot of
`paver width changes from one job to the
`next with one or two foot (0.3 to 0.6 m)
`increments. The versatility of not having
`to drop that mold to make a paver width
`change is something we can do in an hour
`versus half a day.”
`
`The GP3 is also outfi tted with a rear
`loading and front inserting 5400 series
`bar inserter. The inserter uses a bar
`loading chain system so the bars travel in
`a fl at, straight path for maximum placing
`effi ciency. A bar box mounted on the rear of
`the GP3 holds extra bars for easy access and
`loading of the inserter’s bar magazine. A G+
`control box for the 5400 series bar inserter
`is mounted to the rear of the paver and
`manages the bar placements.
`
`One of the fi rst projects the GP3
`
`was put to work on is a new commercial
`development in Sarpy County on Schram
`Road and 140th Street, south of the city of
`Omaha. The paver is being used to slipform
`new roadway, as well as the entrance into
`the development.
`
`“It’s booming in Sarpy County right
`now and for this 40 acre (16.2 ha) site we’re
`paving 3200 feet (975 m) on Schram Road
`and we have 2100 feet (640 m) on 150th
`Street,” Jarrod Ryan, Project Superintendent
`for Vrana, said. “On Schram Road we’re
`paving 25 feet (7.6 m) wide with integral

`(6.4 m) pours for the crowning. We’re also
`going to pour the entrance for the
`development while we’re here and that’s
`26 feet (7.9 m) wide and a third width.”

`“It’s your concrete mix, your slump,
`
`and the machine itself, that allows us to get
`that real crisp, sharp edge,” he said. “It’s a
`perfect edge, the keyway and everything
`on it. The curb is the best curb I’ve seen in
`20 years of paving. We’re happy with the
`fi nal product of the paver and our yields
`have been excellent.”
`
`Finishers working behind the GP3
`have very little to do. Most of the time,
`bull fl oats are left alone along the side of
`the new pavement. A burlap drag fi nish is
`all that’s necessary. A white cure is hand
`sprayed behind the paver.
`
`“We don’t have a smoothness
`specifi cation on this project and I really
`wish we did right now because it’s looking
`good,” Ryan said. “We would have no issues
`meeting it, I guarantee you that.”
`
`“The technology of the machine is
`phenomenal,” Sell added. “Ten years ago,
`I would have never thought of something
`like this, but it has come a long way.”
`
`Part of that technology includes
`telematics and the GOMACO Remote
`Diagnostics (GRD). It allows GOMACO’s
`service technicians in Ida Grove, Iowa, to

`
`The road is being built with future
`
`expansion in mind. The left side of slab has
`a keyway so dowel bars can be drilled and
`inserted to scab-on an additional two lanes.
`The 25 foot (7.6 m) wide pavement has a
`six foot (1.8 m) off set crown and the 21 foot
`(6.4 m) wide pavement will have an eight
`foot (2.4 m) off set crown to accommodate
`the future lanes. The off set crowns are
`
`managed with the 5400 series mold’s self-
`supported, computerized power transition
`adjuster (PTA).
`
`The GP3 with 5400 series mold is
`producing an outstanding new roadway.
`The pavement edges are sharp and the
`keyway design unblemished. According to
`Sell, it’s a variety of factors that combine to
`create a great edge.

`(487.7 m) of 25 feet (7.6 m) wide, nine inch
`(229 mm) thick pavement with a six inch
`(152 mm) integral curb. Paving production
`averaged up to 250 cubic yards (191 m3)
`per hour, which is the production limit of
`the ready-mix plant.
`
`“We have 15 ready-mix trucks
`supplying us and we’re shooting for
`250 cubic yards (191 m3) an hour,” Ryan
`said. “That’s the best ready-mix can do, but
`we can go faster than that with this paver.
`The paver, I guarantee, will go faster than
`that.”
`
`The ready-mix trucks dump the
`concrete into the hopper of a GOMACO
`9500 placer working from the haul road in
`front of the GP3 paver. The concrete mix
`design is a city of Omaha standard 6.5 sack

`missed a bar on any of the pours we’ve
`used it on,” Sell said.

`Hawkins Construction Company
`
`Omaha, Nebraska
`At the beginning of this concrete paving season, Hawkins Construction
`
`Company was in the market for a new concrete slipform paver. The paver
`would need to be versatile, capable of paving at diff erent widths, fi t inside
`urban restraints, and be easily transportable from one job site to the next
`around the city of Omaha. Representatives from Hawkins visited GOMACO
`for a fi rst-hand look at the new GP3 paver. After seeing it in person, they
`knew it was the paver they needed.
`
`“When we visited GOMACO, we looked at the GP3 and saw that it
`would fi t our needs for this year, as well as being very compatible for future
`use,” Todd Allen, Paving Superintendent for Hawkins Construction, said.
`“Having a smaller mainline paver that can pave four feet (1.2 m) wide in
`an urban area was very attractive to us. Then, we can go to 26 feet (7.9 m)
`wide with the same machine, no frame extensions to put in or take out.
`
`The machine with the G+® system works
`together as a cohesive unit, it’s very
`mobile, and gives us the ability to use 3D,
`GPS and sonar.”
