5197 Related Optional Design Methods
For contract plans containing prestressed concrete beam designs
utilizing the old .60 release factor (i.e., designed before
10/1/2010, and do not have the .65 factor usage note on the beam
design sheets), fabricators “may” (mandatory usage if design release
strengths are greater than 5500 psi) employ one of two available
methods for reducing release strengths. Both utilize versions of the
current optional design submittal process. Note: confirm the actual
design release factor used by contacting the designer before
allowing either of the following reduction methods:
- Method 1 – “Modified” Optional Design – a
straight line 7.7% reduction of the release
strength, accompanied by a 500 psi increase of the
28 day strength – just as TxDOT allowed in the
original 2009 version of the research
implementation.
- Method 2 – a “Conventional” Optional Design –
where the fabricator uses the new .65 factor in a
re-design of the beam using Prstrs14 or PGSuper.
See
Research Project 5197 Implementation for additional
information on these optional design methods.
Checklist
1. Validate submittal email
Verify:
- Submittal is sent directly from Fabricator or Detailer
- District’s dedicated shop plan review address is in “CC” field
(when the District is not the reviewer and therefore in the primary
recipient field)
- Contractor’s email address is in “CC” field
- Includes other TxDOT “CC” addresses as directed by the
District (Ex: AE)
- Subject line includes correct CSJ and County
- Optional (alternate) design calculations and associated shop
plan sheets are sealed, signed, and dated by an engineer registered
in the state of Texas (including 5197 related revisions)
- Attachment is .pdf or .dat format with correct file name (see
Guide for additional details)
2. Send confirmation email within two business days
3. Login submittal per office preferences
4. Create project folder on backed up drive
5. Save email and attachments to project folder
6. Open .pdf and save with “R” suffix (Review copy)
7. Review and annotate .pdf (“Red” = permanent)
- Check the Method 1 or Method 2 optional design information for
conformance to 5197 implementation specs
-
Method 1 may only be used on designs using a .60 release
factor – verify by looking for the factor usage note on the beam
design sheets; if this note is not present on post 10/2010 letting
beam design sheets – contact the designer to verify the factor used
in design before allowing a Method 1 reduction
-
Method 1 or Method 2 release strength reductions must be used
by the fabricator on beam designs prior to 10/2010 where a .60
release factor was used and the required design release strength
exceeds 5500 psi
-
Exercise extreme caution in preventing the doubling up of the
use of the .65 release strength reduction factor in both design and
shop plan associated optional designs (doubling the reduction could
cause excessive beam cracking and reduced service life)
8. Stamp all sheets (approved or approved except as noted, as
appropriate)
9. “Save” to preserve Review “R” copy (make sure Rev “N” is also
at the end of the name, where “N” = revision number)
10. “Save as” with “AP”, “AX” or “RC” suffix to denote review
status (again, after Rev “N”)
11. “Flatten” file to remove temporary annotations (other than
“Red”) and embed permanent markups
12. Add Security using office password and allowing printing
13. “Save” final version to apply Flattening and Security
14. Stamp, secure, and save final Optional Design (OD) file
15. Reply, attach, and distribute final review .pdf
- Reply to original email to insure inclusion of “CC” recipients
(the Fabricator or Detailing entity should be the primary recipient)
- Add status suffix to subject line: “AP”, “AX” or “RC” (after
the Rev “N” script)
- Verify District’s dedicated address appears in “CC” field
(when applicable)
- Include Construction Division’s dedicated addresses in “CC”
field
- “CC” Jeff Cotham at
BRG-5197Issues@dot.state.tx.us on all 5197
related “modified” optional designs for the purpose of documenting
the .65 release factor usage
- Include Construction Division’s
printing requirements in body
16. Save reply email to project folder
17. Update office shop plan log
18. Verify email delivered to recipients
