Previously Approved SP
In ProjectWise under Reference Documents/SP Originals there are more previously approved specs from C&T of a more modern vintage that can be retrieved.
Guidance on Use of HMA Initiative
This rescinds the information in Design Update 2006-3 item #1.
FREEWAY AND NON-FREEWAY PROJECTS: (warranted and non-warranted) Superpave – HMA INITIATIVE quantity is the total of all HMA including hand patching, approaches and shoulders (include 03SP504(C) SUPERPAVE HOT MIX ASPHALT PERCENT WITHIN LIMITS (PWL) in the proposal)
CPM PROJECTS: (warranted and non-warranted) Superpave – HMA INITIATIVE quantity is the total of all HMA including hand patching, approaches and shoulders (include 03SP504(D) SUPERPAVE HOT MIX ASPHALT PERCENT WITHIN LIMITS (PWL) FOR CAPITAL PREVENTIVE MAINTENANCE (CPM) MILL AND RESURFACE PROJECTS AND CPM ONE COURSE OVERLAY PROJECTS)
MAINTENANCE FUNDED PROJECTS: Superpave – HMA INITIATIVE quantity is the total of all HMA including hand patching, approaches and shoulders (include 03SP504(D) SUPERPAVE HOT MIX
ASPHALT PERCENT WITHIN LIMITS (PWL) FOR CAPITAL PREVENTIVE MAINTENANCE (CPM) MILL AND RESURFACE PROJECTS AND CPM ONE COURSE OVERLAY PROJECTS)
HMA, TEMP, PAVT, (mix type) No HMA INITIATIVE paid when using FUSP 03SP502U.
MULTIPLE JOB NUMBERS: Treat each job number as an individual project when calculating the HMA INITIATIVE.
VISUAL INSPECTION Projects with superpave hot mixed asphalt should use the appropriate frequently used special provision 03SP504(C) or 03SP504(D) regardless of the amount of tonnage in the project. HMA Quality Initiative may or may not be paid on the project depending on the tonnage in the contract and the approval of the Delivery Engineer. Projects with less than 500 tons of a single mix may be eligible for the use of Visual Inspection (VI) of the superpave mix. If the VI option is chosen, then no HMA Quality Initiative should be figured for the project but a Notice to Bidders should be attached to the proposal stating so. (See attached).
Traffic & Safety Special Provisions
The Traffic & Safety Special Provisions are considered unique and when submitting for The Plan Review and OEC meetings the signing (03T810), pavement marking (03T811 & 812), and the signal (03T819 & 820) Special Provisions should be included along with the respective checklist. The Traffic & Safety checklists are a tool used to compile the Special Provisions. The signing (03T810) and pavement marking (03T811 & 812) can be combined into one checklist and the signal (03T819 & 820) should be a separate checklist.
- To create separate checklists you need to do the following:
- Select the list you want (deselect the others)
- Hit the update button
- Open the checklist.
- Compile the SPs and save the package to your computer.
Checklist for Constructability Review
The Checklist for Preliminary Constructability Review – Early Project Scoping (form 1961) should be included in your Plan Review submittal.
The Checklist for Constructability Review (form 1960) must be completed and signed by both Development and Delivery staff and included in your OEC submittal.
Design Update 2010-2
Plan Review Submittal
Reminder about the procedure for submitting projects for Plan Review through ProjectWise as described in Section 14.36 of the Road Design Manual.
- File names should start with the Job Number i.e.:
- 123456 form 0200.pdf
- 123456 Supporting Documents.pdf
- 123456 Proposal Material.pdf
- 123456 Plans.pdf
- A special provision for all unique pay items should be included even if it is a draft that has been sent for approval.
- Only change the state once on the 3 files in the Plan Review folder. If you change in again you will not be able to update them. The state should be “Plan Review – Submitted for Review.” The QA Unit will change the state again after the project has been scheduled and the meeting notice has been sent out.
- The meeting notice is sent to the Project Manger and Unit Supervisors, anyone working for them that needs be invited to the meeting should be listed on form 0200 in the Special Instructions or Invitees section.
Concrete Quality Assurance
Concrete quality assurance pay item- This pay item is to be used on all projects with concrete except concrete used for pavement repairs. Every cyd of concrete needs to be tested and needs the quality assurance pay item. The FUSP 03SP605B is only used when there is more the 100 cyds of concrete.
The pavement design information (ESAL's) on the new title sheet should be under the traffic data (counts, speed), not along side it.
New DDEP Plan Sheets
MicroStation file names and title block information for the new DDEP plan sheets should be done according to the “MDOT V8i CADD File Naming Standards” that were sent out in the April 2010 Monthly Update. It can be found at the following link:
Drawing and sheet numbers should be included on the plan sheets. Drawing numbers would be unique to each section of the plans (i.e.: typicals, removal, construction, profile, MOT, bridge). Sheet numbers should be consecutive for the entire plan set. The easiest way to place the sheet numbers is to use a footer in PDF file using the following guidelines:
- Current plan format use Arial 8pt right margin 0.45, bottom margin 0.25
- New DDEP plan format use Arial 8pt right margin 0.4, bottom margin 0.3
Below is an example of filling in the title block info.
Designers and consultants should utilize TRANSPORT to generate bid based prices as much as possible. For preliminary estimates, the consultants should send in their SAPW to the MDOT project manager. The MDOT project manager runs the SAPW thru TRANSPORT to generate the bid based prices and then forwards the bid based prices to the consultant to be included in the estimate. The consultant should review the prices for accuracy and make any adjustments as deemed necessary. 7000 items still require the designer and the consultant to estimate prior to completing the cost summary. MDOT's estimators are available to help determine 7000 items prices if needed by contacting Mark Schulick, Steve Ilieff or Rhiannon Worgess-Carveth.
