SCDOT OUTSIDE PERSPECTIVE PRESENTATION

BY

SETH HUFFSTETLER

• Coming up to speed on equipment assets.

• Researching technological advances (Material

Science, Special Coatings, Software, Electrical,

Hydraulics, etc.)

• Communicating with District / County personnel

(product issues & improvements)

• Review and revise equipment specifications

• Initiate procurement contract process

• Product research in an effort to reduce cost and aid

in the goal of updating / reducing the fleet.

• Communication / Coordination with Vendors,

organizing equipment demos for the districts to

illustrate new product concepts in an effort to

improve the way we do business.

Roles & Responsibilities:

Communication:Encouraging Fleet / Design improvements to reduce downtime, repairs, cost, etc. How can we accomplish this?• Vendor communication• Demos / Plant Tours• Meetings with District Management (Buying into a new concept)• Communication with District mechanical engineers (current issues and how to improve)• SCDOT shop foreman discussion board

Vendors are detrimental to our success and they continue to aid SCDOT in product revision / improvement to help us meet our goals.

• Employee & Public Safety

• Product Improvement

Communication with vendors has helped to create and improve existing designs to

provide products that would be SAFER and better suited for our operations and

the public. Communication is instrumental to our success.

DEMO - LED No Diffuser

DEMO - LED Diffuser

FMVSS

Design Revision

Awareness to design changes, items are

being relocated on chassis which creates

fit-up issues & clearance concerns.

Tubing installed to lift tool

storage due to interference with

battery box / air tank location.

331 Hours

$20,000 repair per Tractor Modular design for newer tractors

Bridge Inspection Platform Failure

• Inspection

• Spec. Improvement

• Reduce Downtime

• Reduce Cost / Increased Cost??

(Where to draw the line on expectations)

Protection for Wires (loom, grommets,

strain reliefs, weather protection, etc.)

Mounting, Fasteners, Adhesives

(Heat & Cold Impacts, vibration, etc.)

Equipment not

being used;

opening has

potential to

become a home

for critters.

FACTOR OF SAFETY

Communicating with Vendors and

Districts to ensure items meet the

needs, clearing up any confusion prior

to purchase. Informing the fleet of

OPTIONS to reduce shop fabrication /

downtime cost.

SAFETY

Fleet Data:

• Accuracy of Information (Mileage, Hrs., Utilization, Cost)

• Navigating the Information

Fleet Data - Fleet Improvement (Data Evaluation) / Reduction:

• Fleet - Is there a need, Utilization, Buying, Renting, Contracting, Equipment Pools.

• Product Quality - Materials / components used, SAE / ISO / Codes, history of product

reliability & associated cost after sale.

• Design - examples include: hydraulics, cooling capabilities, weight, dimensions, structural

reinforcement, material selection, special coatings, electrical, etc.

• Support - Before and after sale (product info. & demos are great for highlighting what could

satisfy the DOT needs and after sale support is a key element for our Districts as they

perform the work and eventually do repairs on the equipment).

• Product Improvement - Constant need for improving our specifications without going to

extremes to prevent exponential cost increases associated with our request.

• (Replace) Heat & A/C Components - Approx. $1.79 Million

over 2yrs

• (Repair) Heat & A/C Components – Approx. $850,000

• Total over 2 years = $2.64 Million

• Compressor, A/C Condenser, Evaporator cost = $1.12 Million

Maintenance Cost for Districts (Heat & A/C Summary) :

Backhoe Heat & A/C example:

Downtime associated to Glass repairs over 17 years = 6 months of downtime

“Creature Comforts”

• Period – April 2014 to April 2017

• Repair & Replace Cost on related components = $440,266.88

• Average Backhoe cost = $92,000

• Examples of where money could be spent:

Use toward 15 new 4x4 trucks / 4 new backhoes w/attach. / 6 new compact loaders.

Question from Field Personnel: Do we need A/C on Backhoes & Mini Excavators (Broken Glass

& AC Component Failures)? Why do the new dump trucks have A/C issues?

Self Propelled Sweeper Example

• Avg. Rental Price - $1800/month

• Avg. Purchase Price - $57,600.00

• AC Repair Total - $121,715

• Compiling & Filtering Data

• Researching Possible Issues to

ensure better Spec. coverage

• Predictive Maintenance / Cost

• Initial Cost / Resale Values

Service Cost for 14 Series Trucks

(10yd, Low Boy Tractor)

Field Input:

Supply & Equipment has initiated a discussion board for the State, this allows

shop foreman, supervisors, engineers, etc. to share experiences with one another.

I have used this as a tool to illustrate new equipment, improved designs, highlight

issues with equipment, parts list and pricing. The objective is to open the lines of

communication between the Districts.

Same tool would be great for States

What are we looking at for the future….

16yd. trucks entering the fleet.

New lift design should reduce

body building times, lower the

center of gravity, easier access

for maintenance, and cut body

building cost at the equipment

depot.

Exploring frame options to aid in

snow plow installation.

Explore New Equipment that

emphasizes:

• Utilization

• Versatility

• Increase efficiency

The End of Slope Mower

Tractors????

Lets not forget our Mechanics – Safety, Accessibility, Longevity of Design

• Visibility

• Reliability

• Serviceability (No Aux. Engine)

• Purpose built design

Our Responsibility:

• Safety

• Communication (All Levels, to include other States)

• Fleet Improvement

• Explore New Equipment / Technology

• Strive for Cost Reduction

• Increased Reliability / Efficiency

Who knew that operating

a 1988 Motor Grader with

no AC could be so much

FUN?!!!

And yes, sometimes you just need

to get out of the office….
