Office of Traffic, Safety and Technology 10 Spec Book –Each section is generally divided into the following sections: 1. Description 2. Materials 3. Construction Requirements 4. Method of Measurement 5. Basis of Payment

Office of Traffic, Safety and Technology 11 Spec Book  DIVISION III — Materials –Each Division III Specification number begins with “3” ( ) –Division is divided into eighteen sections

Office of Traffic, Safety and Technology 12 MnDOT Contract Proposal  Contents –Each MnDOT project has a proposal –The proposal contains items such as: Addendums Notices to Bidders Appendices Special Provisions (by division, for example: Division A, Divisions S, Division SS, Division SL, Division ST, etc.) Attachments Contract Schedule (Bid Prices)

Office of Traffic, Safety and Technology 13 Special Provisions  Special Provisions are defined as: –“Additions and revisions to the Standard and Supplemental Specifications covering conditions peculiar to an individual project” –Special Provisions are just that: “SPECIAL” provisions –If an item(s) is adequately addressed or specified in the Spec Book, Standard Plates, Plan, or other Contract documents, then that item(s) should not be duplicated within the Special Provisions

Office of Traffic, Safety and Technology 14 Special Provisions  Topics that are always covered by Special Provisions include –Construction Start Dates –Completion Dates –Traffic Control –Special Pay Items  The Special Provisions need to cover every special pay item from the Plan

Office of Traffic, Safety and Technology 15 Special Provisions  Division S is for general projects  Special Provisions may be formatted into more than one S section –Time and Traffic (Division S) S-1 Contact Information S-2 (1404) Maintenance of Traffic and (2563) Traffic Control S-3 (1710) Traffic Control Devices S-4 (1806) Determination and Extension of Contract Time S-5 (1807) Failure to Complete The Work on Time S-6 (2563) Traffic Control Supervisor

Office of Traffic, Safety and Technology 16 Special Provisions  The following sections can be found in the Special Provisions: –Opening Descriptive Paragraph –General Section –Materials –Construction Requirements –Measurement and Payment

Office of Traffic, Safety and Technology Special Provisions  Special Provision Boiler Plates –Standard special provisions have been developed for use on MnDOT Construction projects –The following is a handout of the “boilerplate” special provisionsspecial provisions 17

Office of Traffic, Safety and Technology Innovative Contracting Methods  Innovative Contracting incorporates new practices to supplement traditional low- bid, design-bid-build contracting  Innovative Contracting Guidelines Innovative Contracting Guidelines 18 Page 6-61

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –A+B Bidding A+B bidding reduces contract time on projects Contractors bid the time to complete the project and a dollar amount for work items The contract is awarded to the lowest combination of time and cost. 19

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –Lane-Rental Lane-rental reduces impacts to the traveling public by minimizing the time lanes are closed Contractors are charged a fee for closing lanes and shoulders due to construction activities The concept focuses on the time that the public is affected, NOT the overall contract time 20

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –Incentives/Disincentives The contractor is paid for early completion of a project as provided for in the contract If the contractor completes the project later than the time allowed, disincentive money is subtracted from payments due 21

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –Constructability Reviews The industry provides valuable feedback into key areas that the Agency may not be able to quantify during the project development process Feedback on preliminary plans has the potential to significantly reduce project costs and construction timelines 22

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –Locked Incentive Date A locked incentive date provides an incentive if the contractor completes the work done early Contractors are not allowed any extensions in the completion date, regardless if extensions are owner caused or not 23

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –Design-Build Design and construction phases overlap, allowing faster overall project delivery 24

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –Pay-for-Performance Pay-for-performance specifications rely on final outcomes measured against performance criteria set forth in the contract If the contractor fails to meet minimum performance criteria, payment is withheld and corrective action is required 25

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –Warranties Warranties require contractors to guarantee all or portions of a construction project to be free of defects in materials and workmanship for a period of time The contractor is required to correct deficiencies that occur during the warranty period. 26

Office of Traffic, Safety and Technology Innovative Contracting Methods  Types of Processes –Critical Path Method (CPM Schedules) Critical Path Method (CPM) schedules are excellent tools for both the contractor and MnDOT to monitor contract time during a construction project 27
