Tell us about self propelled modular transporters l.jpg
Tell us about Self-Propelled Modular Transporters…

  • Why SPMT? Why now?

    • Significantly reduce traffic congestion/impact

    • Open highways to traffic in minutes/hours

    • Improve quality and constructability

    • Improve work zone safety

    • Increase contractor and owner options

What are spmt s l.jpg
What are SPMT’s?

  • Combination of multi-axle platforms

  • Operated through state-of-the-art computer control system

  • Capable of pivoting 360 degrees

  • Lift, carry, and set very large and heavy loads

How do spmt s work l.jpg
How do SPMT’s work?

  • motorized vehicles that move at walking speed

  • carry bridge structures from offsite locations

  • position them precisely into position

  • return area to traffic within minutes or hours

What bridge operations are spmts used for l.jpg
What bridge operations are SPMTs used for?

  • New bridge installation

  • Reconstruction

  • Move & “recycle” entire structures

  • Removal of old structures

Sample of spmt savings l.jpg
Sample of SPMT Savings:

Mobilization cost offset by savings:

  • Fewer/shorter maintenance-of-traffic setups

  • No temporary-detour construction/repair of long-term detours

  • Less user costs from construction-related delay and congestion

  • Better performance of prefabricated structure.

    Contractors reap: lower insurance premiums, more projects, less manpower and equipment rental time

Tell us about automated machine guidance l.jpg
Tell us about Automated Machine Guidance…

  • Why AMG? Why now?

    • Links software with construction equipment

    • Directs the operation of machinery

    • Provides a high level of precision

    • Improves speed and accuracy

Amg also means l.jpg
AMG also means:

  • Less changes, busts, reengineering and rework

  • Less labor /time to produce high quality results

  • Improved worker safety

  • Agencies/contractors save time and money

  • Better ride quality for customers

How does amg work l.jpg
How does AMG work?

  • Three-dimensional computer models to move materials with precision

  • Info via GPS about how much to move or aggregate level

  • Machine controls materials while operator drives down roadbed

Amg holds promise for l.jpg
AMG holds promise for:

  • Curb placement

  • Paving

  • Trenching

Tell us about construction analysis software tools l.jpg
Tell us about Construction Analysis Software Tools…

Why CAST? Why now?

  • CAST provides Information on construction options that helps agencies:

    • “Try before they buy”

    • Minimize traffic congestion during congestion

    • Maximize safe mobility

    • Gather and organize data for IA and TMP, per new FHWA rule

Use cast for l.jpg
Use CAST for:

  • Planning

  • Design

  • Implementation

Cast options include l.jpg
CAST options include:

  • Traffic simulation/analysis

  • Traffic management

  • Construction scheduling/cost analysis

  • Combination of these options

Cast decision factors include l.jpg
CAST decision factors include:

  • Analysis context

  • Tool category

  • Most appropriate tool within category

Tell us about precast concrete paving slabs l.jpg
Tell us about Precast Concrete Paving Slabs…

Why PCPS? Why now?

  • Proven quality, durability and long-term performance

  • Accelerate construction scheduling and sequencing

  • Reduce work zone duration and size limits

  • Reduce construction delays/congestion

  • Economically viable
