PROJECT AREA

01

Equivalent Products

Whenever in the Drawings any material is indicated or specified by name of manufacturer, such Specifications shall

be deemed to be used for the purpose of facilitating description of the material desired and shall be deemed to be

followed by the words “or Engineer approved equal”, and the Contractor may offer any material which shall be

equal in every respect to that so indicated or specified; provided, however, that if the material or article offered by

the Contractor is not, in the opinion of the Engineer, equal in every respect, then the Contractor must furnish the

material or article specified or one that, in the opinion of the Engineer, is equal thereof in every respect. The basis

of payment for Salvage, Stockpile and Place Granular Base Material shall be plans quantity. No separate

measurement shall be made. Water for placing salvaged granular base material shall be considered incidental to the

installation of Salvage, Stockpile and Place Granular Base Material; no separate payment will be made.

Substantial Completion

Substantial completion will consist of all bid items. If the Contractor fails to substantially complete the project,

liquidated damages shall be assessed to the Contractor as set forth in paragraph SC15.11.

Working Day Count

The Contractor shall complete all substantial work by May 22, 2026 with final completion by June 22, 2026. In

addition, the Contractor will have 38 consecutive working days to substantially complete this project. If the

Contractor fails to substantially complete the project within the allotted working days, liquidated damages shall be

assessed to the Contractor as set forth in paragraph SC15.11. The Contractor is required to submit a starting date at

least 48 hours prior to work beginning. The working day count will start on the date submitted by the Contractor

and working days will consist of Monday through Friday. The City will not count weekends or holidays unless

work is being performed. Work consists of any Contractor or Subcontractor on site performing any duties, except

adjusting traffic control.

Weather Days

Initially, the Contractor and Engineer should get together and discuss whether the conditions warrant working or

not working. If the Contractor and Engineer both agree that the conditions are such that working is not possible,

then the day or partial day is a non-working day due to weather. The City anticipates 2 weather days per month. If

the Contractor believes that work cannot be performed in the weather conditions due to low efficiency or other

reasons and the Engineer believes the Contractor could work without major hindrance, then the decision will be

based upon the weather data for that site for the day in question. If the precipitation over the full day of work in

question before the time of shutting down is greater than or equal to 0.3 inches of precipitation (rain or snow

equivalent), then it is an adverse weather day. If the precipitation value is less than 0.3 inches of precipitation (rain

or snow equivalent), then it is a working day. If it rained greater than 0.75 inches the previous day, then it is an

adverse weather day for grading projects only.

Construction Staking

The Contractor is responsible for elevations, drainage, and meeting ADA requirements unless the area is

determined problematic by the Engineer, in which case the Engineer will provide all necessary staking.
