LPA Materials

LPA Materials Responsibility?

During Project plan Development

Use ODOT materials specifications

or

If Developing your own materials specifications, obtain approval from ODOT for those non ODOT materials

Require acceptance by FHWA

LPA Materials

Step 1 – Pre bid materials checklist

Evaluate your project for standard, non standard, as per plan, or item special materials.

On line at the OMM Local Projects webpage

Local Projects Webpage

On line check list

LPA Pre Bid Checklist

4

LPA Materials

Step 1 A

Come up with a Bill of Material for your project

Part of the Pre Bid Checklist!!

If you don’t have a understanding of this you can go to the OMM website on Local Projects

LPA - Project BOM

Come up with number of tests needed

The spec book can help

The Sampling and Testing manual can help with sampling and testing requirements

Step 3

Pre-construction meeting!

Contractor provide records of suppliers

LPA - Contractor Supplier list

Now you can check for certified suppliers

check for QPL materials

Check for concrete plant and asphalt plant approval

Check for steel or prestressed fabricator approval

Find issues before delivery of materials

6

What are Typical Material Docs?

TE24

QPL (tag – some identification)

Certified Test Data Materials Piling? As per plan? Specialty?

Steel/concrete beams

(shop drawingsTE-24)

Aggregates - (tickets)

Concrete - (JMF, tickets, samples, test data)

Asphalt - (JMF, tickets, samples, test data)

7

TE-24 - What to look for?

Paper copy of TE24s

Rebar, catch basins, guardrail, etc.

Generally – any certified supplier

Certified Supplier List

Suppliers often say they cannot create

TE24s without an ODOT project

number- Untrue

-can call Abdul Qayum at OMM

8

QPL - What to look for? Info on the material that shows

producer – brand name

Electrical wire, cable, PVC, RPMs, iron pipe,

concrete sealers, etc.

Can verify on QPL website at LPA

office/trailer or back at district office

ODOT issue – no proof –

documentation of QPL – means

contractor and payment issues

9

Certified Test Data (CTD) What to look for?

Check files for test data

H-piles, cast pile points, shear studs,

CTD

It is not a certificate of compliance

ODOT Issue

Has the LPA checked the test data for

compliance to specs?

Needs to match up!

10

What will ODOT look for?

Special items As per plan items

Check files for LPA approval paperwork

Special Lightpoles, brick type retaining wall,

etc. etc.

Do the plans allow for these items?

ODOT often has issues with these items

11

Steel and Concrete Beams

Steel and Concrete Beams

Contractor Approval of Shop Drawings

Your Approval of Shop Drawings (not ODOT)

OMM inspection with TE24

ODOT issues

No inspection? If not done – will require

special consultant inspection – your cost

12

Aggregates - What to look for?

Aggregates

Supplier qualified for size, not just listed

304, 617, sand, 8s, 57s for various applications,

bedding & backfill

Aggregate Pre-Qual Iist

Do tickets state “ODOT Pre-Qualified

Aggregate Supplier”?

ODOT issues – certified supplier doesn’t

mean they are certified for all

13

Concrete - What to look for? Plant approved

Approved JMF for mix type

Tickets have JMF, batch weights, agg

moistures?

Test results for air, slump, yield,

strength?

Test results meet spec?

ODOT issues – no JMF – no supplier –

no tests

14

Asphalt - What to look for? Most problematic material for LPAs

Have approved JMF?

JMF on tickets?

Do you have monitoring, sublot sampling VA samples?

Are checked against spec tolerances,

Are matched to contractor results, rice and pill split sample testing, etc.

District Testing can be contacted to help with review of information

Can district monitor? Can they test?

15

Recap on what to do

1. Complete the Materials Check List

Before FHWA Funds Approval

2. Develop you tracking system (PBOM)

before project

3. Require Contractor/Supplier list

complete before construction

4. Get a consultant for Asphalt

monitoring and Testing

5. Structures? – Get ODOT to inspect
