This includes the four key elements:
SCHEDULE OF APPROXIMATE QUANTITIES AND UNIT PRICES
Project No: 21583-0001
Project Name: Trans Canada Highway No. 1., between 30th Street NE and 20th Avenue NE in Salmon Arm and Highway No. 97B, between 10th Avenue NE and Trans Canada Highway No. 1
- as outlined previously, staging and detours, if required, is to
be provided in the contractual drawings or special provisions.
- payment would be made to the contractor for staging/detours
in the contract drawings or special provisions.
- contract payment mechanism may be in a variety of methods:
- best practice is quantities and/or lump sum.
- contractor is responsible for handling the
unexpected such as traffic surges, incidents,
- TMP changes due to contractor’s work
activities are the contractor’s responsibility
- TMP changes due to scope changes or other
ministry changed condition responsibilities are
to the ministry’s account
- too flexible or too structured; both opinions have
- base tender information will be provided as special
provisions, drawings or information.
- value engineering is a contractor’s choice if innovation
is sought. After contract award.
- however, any alternate TMP has to meet all
contractual requirements and Traffic Management
- alternate TMP prepared and produced at Contractor’s expense.
- for implementation of TMP; to keep to contractual requirements –
closure window or traffic delay.
- generally the ministry endorses bonus/penalty clauses as incentives to excel.- is shown to work well with paving quality and time.- is being used on the Sea to Sky Project.
- has been used in Arizona but somewhat expensive.
- not a nickel and dime approach.
- for general use must be relatively understandable and straightforward to use.- low cost for both contractor and ministry to obtain data, interpret and apply.- we have searched for an easy to use sample – no results.- volunteers are welcome to develop a clause that meets the above
- with considerably more effort in the engineering phase underway, we have higher
expectations that contract requirements are met.
- as well, given the ministry will have communicated with road users and stakeholders with respect to traffic outcomes (i.e. delay times, closure windows, lane closures, communication, etc.), the expectations of our road users and stakeholders will have
- therefore a higher level of compliance and consistency will be set.
- we expect a key element of a contractor’s quality control plan to address the TMP
preparation and execution. Expect quality assurance by the ministry.
- in the future, we anticipate reporting out by contractor in meeting traffic
- contract requirements call for QMP and TMP
- contractor to name Quality Manager (QM) and Traffic Control Supervisor
- contractor names a QM offsite and an inexperienced Traffic Control Supervisor (same person also named to other named duties as well)
- Payment adjustments for non-compliance
- careful reviews by the ministry of the QMP and TMP once the
contractor has completed their quality review
- contractor to be accountable for:
- any deficiencies in the TMP and QMP - to ensure their own compliance with QMP and TMP - taking corrective actions when required
- periodic auditing
- Stop Work Orders for material non-compliance of TMP
- to start work in traffic without an accepted QMP and TMP
- ministry to hand over a corrected QMP and TMP
- paving contract advertised and tendered- to mill and fill a 2-lane highway- with 2 lanes open at all times
- this type of contract requirement not to be enforced - not this type of contract
