Planning for Innovative Technology Slide 2 Every Day Counts Rapid changes face the highway community in the 21st century Adapting to those changes must be a central focus of the FHWA. Every Day Counts captures a sense of urgency with which we must pursue innovation. Every Day Counts seeks to identify and deploy innovation as its highly focused mission. Innovation will enable us to become faster, better and smarter. http://www.fhwa.dot.gov/everydaycounts/ Slide 3 Grant Application Process 3 Find Grant Opportunity for which you would like to apply Download Application Package Complete the Registration Process Complete and Submit the Application Package 3D Engineered Models for Construction Geosynthetic Reinforced Soil-Integrated Bridge System Prefabricated Bridge Elements and Systems Slide-in Bridge Construction First Responder Training Geospatial Data Collaboration High Friction Surfaces Design Build Alternative Technical Concepts Construction Manager/General Contractor Intelligent Compaction and Construction Intersection and Interchange Geometrics Locally-Administered Federal Aid Projects Implementing Quality Environmental Documents Programmatic Agreements Slide 4 Strategic Highway Research Program (SHRP) http://www.fhwa.dot.gov/goshrp2/ Slide 5 EDC2 Initiatives Geosynthetic Reinforced Soil Integrated Bridge System (GRS-IBS) Construction Manager / General Contractor (CM/GC) Slide 6 GRS-IBS GRS Geosynthetic Reinforced Soil An engineered fill of closely spaced (< 12 ) alternating layers of compacted granular fill material and geosynthetic reinforcement IBS Integrated Bridge System A fast, costeffective method of bridge support that blends the roadway into the superstructure using GRS technology Slide 7 Simplicity of GRS Three Main Materials A row of facing block A layer of geosynthetic Well compacted granular backfill Slide 8 Benefits Reduced construction cost (25 60%) Reduced construction time Construction less dependent on weather conditions Flexible design easily field modified for unforeseen site conditions (e.g. obstructions, utilities, different site conditions) Easier to maintain (fewer bridge parts) Slide 9 Site Selection Single span (currently 140 ft. max) 30 ft. abutment height Steel or concrete superstructures Water crossings with low scour potential New or replacement structures Grade separation Slide 10 Huston County, PA Challenges: Emergency closure in July School bus route NO use of alternate route after October 31 NO work in stream after October 1 Slide 11 Actual abutment construction time: 6 days! Total time of road closure: 112 days Time Savings Slide 12 Comparable Cost Data Local Project Box Culvert (no paving costs) Locally bid and built with local forces $194,000 Huston Township Actual Project Costs Soup to Nuts $101,894 Contracted Design and Construction Box Culverts $500,000+ Slide 13 Defiance County, OH St Lawrence County, NY In-Service GRS bridges Defiance (30) St Lawrence (14) Both counties have a consistent savings of 50% when using county labor. Defiance County saves approximately 30% when project is bid. Two Bridges for the Price of One Bridge takes 10 days to Construct Beginning GRS Abutment Precast Beams Placed Complete Slide 14 Ease of Construction Typical Sized Labor Crew with a Centrally Located Track hoe Slide 15 Construction Manager/General Contractor (CM/GC) Designer and Contractor work collaboratively to develop the project scope, optimize the design, improve quality, and manage costs Owner Construction Manager Designer Slide 16 Accelerated Project Delivery Design Bid Build (D-B-B) Low bid legacy delivery system Agency responsible for errors and omissions Design Build (D-B) Single point of responsibility contract Minimal owner control Construction Manager / General Contractor (CM/GC) Three way partnership Owner led Slide 17 Virgin River Trail Washington City, Utah Construction Manager helped determine trail alignment Contractor input eliminated blasting and minimized excavation Saved $200,000 Slide 18 Bitter Creek Bridge Grand County, Utah Originally slated for full replacement at $4.0 M Resulted in simple bridge girder repair Final cost was $400 K Slide 19 A Tale of Two Bridges Same Project Manger Different Outcome Pennywash Creek Bridge 0 CM/GC delivery method 0 5 week delivery 1 week ahead of schedule 0 10% under initial budget 0 Designed around pre-fab girder 0 No claims, no change orders Kemper Road Bridge 0 Low- Bid system 0 5 week delivery 1 month behind schedule 0 30% over budget 0 Change orders and claims during construction Slide 20 What You Should Know CM/GC is a qualifications-based, negotiated-price contract Requires a teaming mentality CM can be brought into the project at any phase Experience shows biggest benefit is at the start of the project Owner needs to be open to new ideas Team adopts a no change order philosophy Slide 21 1.Innovation 2.Reduction of Risk 3.Aggressive Delivery 4.Cost Management 5.Team Selection 6.Constructability 7.Streamlined Plans 8.Quality 9.Early Work Packages 10.Flexibility in Changing Project Scope Reasons for CM/GC Top Ten Reasons for CM/GC Slide 22 CM/GC Partnering with Locals How Can You Increase Local Participation? 1)Determine sub-contracting capabilities prior to plan development 2)Incorporate Local specialty work items into the project 3)Provide an equal seat at the table in project planning, development, and construction 4)Bring Sub-contractors into the process early as advisors to the Owner - relating to constructability and means & methods 5)Split bid items into multiple bid packages - enable Locals to build the volume of work that fit their capabilities CM/GC enables a Project & Program to be tailored for Local trades abilities, specialties, & bonding capacities -- enabling Locals to be fully engaged in a Project from Beginning to End Slide 23 23
