above that were not approved by the District will not be accepted or

3. TIME OF DELIVERY AND QUANTITIES

a. Individual orders for jobsite delivery of material and their required time of

arrival at the respective jobsites will be placed as the day to day job

requirements become known. Whenever possible, the contractor will be

given one day's prior notice of delivery requirements and arrival times.

Deliveries may often be required on the same day that notification is

given. In this event, two (2) to four (4) hours' advance notification will be

given to the Contractor, and the quantities ordered in this instance will not

exceed the hauling capabilities of two trucks to any one jobsite or a total

of four trucks to all jobsites.

b. If the Contractor is unable to deliver the material as required under the 2

the order within 15 minutes after the order is placed. District may then

seek to place the order with another vendor. Since time is of the essence,

in the event Contractor makes 4 such declinations or “non-response” in

any continuous 4-week period, the District may suspend future orders and

only resume at the discretion of the District when deficiencies have been

satisfactorily addressed. Continuing failure to deliver as requested may

result in cancellation of the contract.

given day for each region awarded to the contractor pursuant to this

agreement. The contractor is not required to deliver more than 600 tons

per day for each region awarded to the contractor pursuant to this

agreement. If, for example, a contractor is awarded two regions, their

daily minimum delivery expectation will be 1,200 tons (600 tons X 2) per

day; 3 regions equal 1,800 tons, etc.

d. Contractors are encouraged to bid on one or all regions. If a contractor is

unable to meet the delivery requirements or do not deliver to the location,

indicate N/A.

e. If a contractor is bidding on multiple regions, the contractor shall

indicate/designate the number of regions they are capable and expected

to satisfy should they submit the lowest responsible bid for multiple areas.

For example, bidder submits bids for all five regions but only has the

capacity to supply 1,200 tons per day. The bidder shall indicate to the

District in their bid that they will not accept the award of more than two
