Additional Terms and Scope of Services

1. The gravel crushed shall meet the Gravel Crushing Sieve Specifications as shown on

Attachment “A”.

2. The Thompson Pit is located adjacent to the Neal Pit. Crushing will be continuous between

the two pits. Since the Neal Pit is leased, quantities of material crushed in the Neal Pit will

need to be tracked separately from the Thompson Pit material.

3. Material Testing:

a. Contractor shall have a qualified, independent laboratory perform a sieve analysis

test at approximately 500 tons at the beginning of each crush, and thereafter shall

run additional tests at approximately 3,000 ton intervals. Sieve analysis test and

fractured face test results shall be given to the County Public Works Director or

designee by end of business the work day following the sample day.

b. Material codes 509 and 510 require an Atterberg Limits (plasticity index) test per

ASTM D4318 conducted in conjunction with each sieve test. Plasticity Index tests

results shall be provided within three working days of the sample day.

c. All testing costs shall be the responsibility of the contractor. Montrose County may

perform additional tests at its discretion and will bear the cost for such additional

tests.

4. If a product is found to be out of specification on any test, and the contractor fails to meet

specifications with any subsequent test, the County shall have the option to:

1) Stop all crushing operations until the Contractor makes necessary corrections and

can prove that specifications are being met;

2) Negotiate a reduced compensation for the out of specification product.

Compensation for the out-of-specification material shall be paid at a rate not to

exceed 50% of bid price;

3) Have the out-of-specification material reprocessed into a usable product that meets

a different specification. Contractor shall only be paid at the bid unit rate for the

reprocessed specified material. No payment will be made for the initial out-of-

specification material;

4) Request that additional material be crushed at contractor’s expense to make up for

the out-of-specification material;

5) Any combination of the above.

6. Consistent out-of-specification performance shall be sufficient grounds for termination of

the contract and claim for damages including claims against contractor’s bond.

7. All gravel shall be measured using certified belt scales placed after the screen in the

crushing circuit to capture the pay quantity(s). The County Public Works Director or

designee shall be present for verification of the belt scale readings. Contractor shall notify

the County Public Works Director or designee at least 24 hours in advance of a belt scale

reading.

4

8. Scales shall be certified by a third party prior to the first crush in each pit.

9. Scale recertification will be done after half of the material is crushed in each pit and after

each move within a pit. The recertification may be done using a County truck load of

crushed material weighed at a separate certified scale. If scale agreement is not obtained

after weighing three (3) truck loads, the contractor shall have a third party recertify the

scales.

10. Locations and quantities to crush are outlined in the Estimate of Gravel Crushing

Quantities per Location as shown on Attachment “B”.

11. The order and priority for County gravel crushing operations shall be determined by the

County Public Works Director or designee, and may be negotiated with the Contractor with

an attempt to minimize the number of moves for the crushing equipment.

12. Extraction locations and placement of stockpiles will be at the direction of Montrose Public

Works Director or designee.

13. Montrose County will remove overburden and level a pad for the crusher prior to the crush;

and push down high walls, slope/re-grade disturbed areas after crushing operations have

ceased.

14. *Contractor shall push pit run to the crusher, maintain high walls during crushing

operations, and move additional dirt within the pit as needed to meet the specification for

dirty road base.

15. If necessary to meet gravel specifications, Montrose County will haul and stock pile

dirt/fines not available at the pit site to an agreed upon location within the pit prior to

crushing.

16. Contractor shall maintain, and leave a level pit floor after crushing is completed. Pit is to

be left free of trash and debris. No onsite disposal of waste is permitted.

17. Contractor is responsible for dust control during crushing operations and for obtaining

water for dust control, as required.

18. Montrose County may ask to haul gravel while crushing is in progress. The Road & Bridge

Superintendent or designee will seek permission and coordinate with the crushing

contractor should this occur. Contractor shall have control of the pit while crushing is being

performed and must adhere to all applicable regulations; therefore, permission to haul is

not guaranteed.

19. All costs except the mobilization costs are to be included in the bid price per ton. The

“Mobilization to a Pit” bid price will be charged once for each pit. If a move within a pit

becomes necessary and is approved by Montrose County, the “mobilization within a Pit”

bid price will be used for payment.

20. Crushing times shall be from 7 am to 6 pm Monday through Friday. Work on weekends

will be allowed on case by case basis, depending on the gravel pit.

21. Crushing in all pits shall be completed no later than November 8, 2026, unless written

permission by the County is granted to extend the completion date.
