1. Project Objectives

The objective of this contract is to complete construction as quickly as possible while minimizing the impact to the Stakeholders. The Stakeholders are, but not limited to, the adjacent businesses, schools, commuters, buses, emergency services, pedestrians, bicyclists, and adjoining neighborhoods. As such, this work will be accomplished in an orderly manner as defined herein.

Driver and pedestrian/access shall be maintained during the construction of improvements.

Temporary paved access shall always be provided by the contractor to meet the Americans with Disabilities Act (ADA) requirements. The contractor is advised that an approved construction sequencing scheme meeting the intent of the project objectives will need to be followed. Once approved, the contractor shall follow the phasing plan unless modified by the Engineer in writing.

2. Project Limits and Restrictions

The contractor shall perform all work within the public right-of-way, legally obtained easements including temporary construction easements (TCEs), legally obtained rights-of-entry (ROE), and legally acquired property by the City of Tucson. The contractor shall assume all responsibility and liability for any encroachment upon private property. The use of private property for construction yards will be allowed only if zoning requirements allows its use for this purpose – see Section 106-9 of the Standard Specifications for further details regarding temporary construction yards. The cost of the construction yard is considered incidental to the project.

Under no circumstances shall any equipment, vehicles or other construction items, not specifically required or needed for the immediate construction at hand, be stored or left on private property without the express written permission of the property owner.

The contractor shall field verify all existing conditions shown on plans and specified herein prior to beginning construction. Any significant deviations to the conditions that may affect the timely construction of improvements shall be brought to the attention of the Engineer within 24 hours of discovery. Prior to delivery of any equipment, materials or supplies to the site of any work, or the beginning of any construction work, it is strongly recommended that the contractor take pre-construction photos or videos as deemed appropriate for establishing the conditions existing in all the areas that may be affected by the construction.

SP-13

3. Contract Time

Once the contract has been awarded and signed, the contractor shall be issued a Notice to Proceed (NTP). This will begin Phase 1 of the project, the construction phase, and the contractor shall have 550 calendar days to complete this work as shown on the project plans and as specified herein.

Phase 2 of the contract shall encompass the 24-month (730 consecutive calendar days) Landscape Establishment period as detailed in Section 807. All other items of work shall be completed and accepted (via acceptance of the roadway and/or drainage phase of the work) by the Engineering Representative prior to the commencement of Phase 2. The contractor shall obtain the acceptance of the previous phase(s) following a Final Inspection of that phase.

If the Final Inspection should reveal work that is not completed or is unacceptable to the Engineer for any reason, a "punch list" of these items shall be generated and provided to the contractor. Substantial completion (for the purpose of stopping the contract time) will be granted in accordance with Section 105-21 of the Standard Specifications.

Once substantial completion is granted, the contractor shall actively work to achieve final acceptance of the construction phase of the contract within 15-calendar days from the substantial completion date of that phase. Failure to prosecute the remaining work within this time period will result in the resumption of time charges and the application of liquidated damages from the date scheduled for final acceptance.

When the work on this list has been satisfactorily completed, final acceptance of the phase(s) shall be given for all items of work other than Landscape Establishment. At this time the Landscape Establishment period shall begin, and the monies retained for all items of work other than Landscape Establishment (ITEM 8070001) shall be released.

Through the duration of the Landscape Establishment period, the Agency shall retain 10% of the cost of the aforementioned items of work or a minimum of $2,000.00, whichever is greater. (The amount retained for ITEM 8070001 shall not exceed 5% of the total contract bid amount).

Upon completion of the Landscape Establishment period, a final inspection will be held with Engineering and Streets Division staff to ensure that all plants are healthy and acceptable.

Prior to delivery of any equipment, materials or supplies to the site of any work, or the beginning of any construction work, it is strongly recommended that the Contractor take pre-construction photos or videos as deemed appropriate for the purpose of establishing the conditions existing in all the areas that may be affected by the construction.
