Contract Documents Construction Documents PLANS
Contract Documents • CIB specifies applicable SS edition. • Note: Some Special Provisions REVISE the SS. • Section 105.04 • Some legal mumbo jumbo you don’t need to build the job. Right?
Contract Documents • Section 105.04 • Illustrates importance of being clear and consistent!!!
Construction Documents Recurring Special Provision: 107-R-169 • Always check for and use current version posted on INDOT website. • Adaptable. Covers most situations. • Uncommon Utility situations may require Unique Special Provision (USP) • USP must be clear and defendable • Consult INDOT Utility Section!!! • For added clarity….list relocations first • UC is responsible to be sure the information shown here matches the relocation plans/documents.
Construction Documents Does all of this information agree with all of the other construction documents??? • Plans, Special Provisions, Utility Agreements, Relocation Plans, etc. • IT SHOULD IF UC DID THEIR JOB! Example Special Provision It is OK to add email addresses here.
Construction Documents Example Special Provision Are these dates and durations accurately reflected in Gantt Chart? Have you, as UC, followed up regularly with Utility to confirm? BAD WORDS
Construction (Post Letting) • We made the letting • We have a low bidder • The contract is awarded • Utility Coordination is OVER! • It’s construction’s problem now…. Wrong!
Construction (Post Letting) • Utility Coordination will take place until the relocations are complete! • Pre-construction Conference • Generally first time all parties meet • Field Staff • Contractors • Designers • Utilities • Others • All have different responsibilities • UC will be proactive in making sure Utilities engage!!!
Construction (Post Letting) • Utility Coordination • All jobs have some form of progress meetings • Utility Coordinator should attend until a point where coordination efforts are no longer needed. • If proactively communicating with utilities and field staff: Coordinator is not there to learn what is going on but should be educating others as to what is current, what is coming, and what is complete!
Construction (Post Letting) • Typical Project • Survey • Clearing right-of-way • Contract documents contain information regarding status of utilities and how relocation work relates to Survey and Clearing R/W • It benefits everyone (INDOT, Contractors, Utilities, Public) to work together to progress the work to complete projects on time and on budget.
Construction (Post Letting) • Shop Drawings • Example: Mechanically Stabilized Earth (MSE) Retaining Walls. • Vendor Systems vary. • What is shown in the plans is typically less than what is submitted in Shop Drawings. • Lengths and Elevations of Leveling Pads vary slightly from plans. Can effect Underground Utilities.
Mislocation • Scenario: • PE/S calls you and says they found a water service line that is 15’ away from where it was shown on the plans and is in conflict with a new curb inlet. Contractor moved on to other pipe and structure work but said he needs to complete this within a week to stay on schedule. Water company has had other relocation work and is non-reimbursable. • What are our options? What do we do? • (Open Discussion)
Mis-relocation • Same Kind of Scenario: • PE/S calls you and says a water service line was relocated 15’ away from where it was shown on the approved relocation plans and is in conflict with a new curb inlet. Contractor moved on to other pipe and structure work but said he needs to complete this within a week to stay on schedule. Water company has had other relocation work and is reimbursable. • What are our options? What do we do? • (Open Discussion)
Mis-Coordination (Uh Oh) • Scenario: • PE/S calls you and says a water service line was relocated to the line and elevation on the approved relocation plans but is was cut when the contractor excavated the new ditch. • This WILL be a thing of the past. • Very typical example of past problems. • This is why drawings of significant detail and constructability reviews are so important. • Discussion
