Revision of Section 104 – Scope of Work

Section 104 of the Standard Specifications is hereby revised for this project as follows:

Subsection 104.02(a) shall be deleted and replaced with the following:

(a) Differing Site Conditions. It is the County’s expectation to complete this project with no change orders resulting in additional cost unless such change orders are initiated by the County. Change orders for differing site conditions will be entertained by the County in the event of extraordinary circumstances. However, the County is under no obligation to approve said change orders. No cost change orders, reduction in cost change orders, and County initiated change orders may occur.

The Contractor shall not be entitled to a change order for Differing Site Conditions. By way of example, Differing Site Conditions not eligible for a change order include but are not limited to:

(1) Encountering groundwater.

(2) Discovery of debris (buried or unburied within the ROW).

(3) Existing asphalt thicknesses that are different than expected.

(4) Increased costs or delays due to relocations of utilities and/or oil and gas facilities.

(5) Increased costs due to ROW or easement acquisitions.

(6) Discovery of unknown or private utilities such as water, sewer, gas, electric, phone, irrigation, oil, etc.

(7) Discovery of septic systems, leach fields, or other ancillary wastewater infrastructure.

(8) Discovery of unknown irrigation facilities, landscape irrigation systems, or water wells.

(9) On-site soils not suitable for structural foundations or embankments.

(10) Unsuitable materials excavation.

(11) High water levels in drainageways due to stormwater runoff or snowmelt. The Contractor shall be expected to manage the risks associated with flows in the drainageways in order to meet the project completion date.

(12) Frozen ground.

During the progress of work, if extraordinary conditions are discovered, the party discovering such conditions shall promptly notify the other party in writing of the specific conditions before the site is disturbed and the affected work is performed. The Contractor shall bear the burden of proving that a Differing Site Condition is an extraordinary circumstance, and that the Contractor could not have reasonably worked around the condition so as to avoid additional costs. Each request for a change order relating to a differing site condition shall be accompanied by a statement signed by a qualified professional setting forth all relevant assumptions made by the Contractor with respect to the condition of the Site, justifying the basis for such assumptions, explaining exactly how the existing conditions are eligible for a change order under the terms of the Contract, and stating the efforts undertaken by the Contractor to find alternative design or construction solutions to eliminate or minimize the problem and the associated costs.

Upon written notification, the Engineer will investigate the conditions, and determine if an extraordinary condition exists that will cause an increase or decrease in the cost or time required for the performance of any work under the Contract, an adjustment, excluding anticipated profits will be made and the Contract modified in writing accordingly. The Engineer will notify the Contractor of the determination whether or not an adjustment of the Contract is warranted. No Contract adjustment which results in a benefit to the Contractor will be allowed unless the Contractor has provided the required written notice.

Subsections 104.02(c)(1) and 104.02(c)(2) shall be deleted and replaced with the following:

(1) When the character of the work as altered differs materially in kind or nature from that involved or included in the original proposed construction, and

(2) When a major item of work is increased in excess of 150 percent of the original contract quantity or decreased below 25 percent of the original contract quantity. Any allowance for an increase in quantity shall apply only to that portion in excess of 150 percent of original contract item quantity, or in case of a decrease below 25 percent, to the actual amount of work performed. A major item is defined to be any item having an original contract value in excess of 10 percent of the original contract amount.

Revision of Section 105 – Control of Work

Section 105 of the Standard Specifications is hereby revised for the project as follows:

Subsection 105.01 shall be revised to include the following:

Weld County has the authority by written order to suspend the Work wholly or in part for the reasons outlined in the Contract Documents.

All the Contractor’s employees shall have the skill, experience, and any licenses or certifications required to perform the Work assigned to them. If the County determines, in its sole discretion, that any Person employed by the Contractor or by any Subcontractor is not performing the Work properly and skillfully, then, at the written request of the County, the Contractor or such Subcontractor shall remove such Person and such Person shall not be re-employed on the Project without the prior written approval of the County. The employee shall be removed from the project as soon as possible but in an amount of time not to exceed 24 hours. If the Contractor or the Subcontractor fails to remove such Person(s) or fails to furnish skilled and experienced personnel for the proper performance of the Work, then the County may, in its sole discretion, suspend the affected portion of the Work by delivery of written notice of such suspension to the Contractor. Contract time shall not stop but shall continue as specified in the Contract. Such suspension shall in no way relieve the Contractor of any obligation contained in the Contract Documents or entitle the Contractor to a Change Order. Additionally, pay reductions shall be assessed in accordance with Subsection 108.12.

Weld County, in its sole discretion, may require the Contractor to replace project management staff (Project Manager, Superintendent, Project Engineer, etc.) for any reason. This will also apply to all the Contractor’s subcontractors. At the written request of the County, the Contractor or such Subcontractor shall remove such Person and such Person shall not be re-employed on the Project without the prior written approval of the County. The project management staff shall be removed from the project as soon as possible but in an amount of time not to exceed 7 calendar days. If the Contractor or the Subcontractor fails to remove such Person(s), then the County may, in its sole discretion, suspend the affected portion of the Work by delivery of written notice of such suspension to the Contractor. Contract time shall not stop but shall continue as specified in the Contract. Such suspension shall in no way relieve the Contractor of any obligation contained in the Contract Documents or entitle the Contractor to a Change Order. Additionally, pay reductions shall be assessed in accordance with Subsection 108.12.

Subsection 105.03, paragraph 5 shall be deleted and replaced with the following:

When the Engineer or Inspector finds the materials furnished, work performed, or the finished product are not in conformity with the Contract Documents, and Weld County determines, in its sole discretion, that it has resulted in an inferior or unsatisfactory product, the Work or Materials shall be removed and replaced or otherwise corrected by and at the expense of the Contractor.

Subsection 105.03, paragraph 7 shall be deleted and replaced with the following:

Materials will be sampled and tested for Owner Acceptance by Weld County per the sampling and testing schedules and procedures contained in the Contract Documents and in CDOT’s Field Materials Manual. The quantity represented by five consecutive random samples will constitute a lot whenever production schedules and material continuity permit. The Engineer may establish a lot consisting of the quantity represented by any number of consecutive random samples from one to seven inclusive when it is necessary to represent short production runs, significant material changes, or other unusual characteristics of the Work. Tests that are determined to have sampling or testing errors will not be used. The Contractor will not have the option of accepting a price reduction in lieu of producing material that complies with the Contract Documents. Continued production of nonconforming Material will not be permitted. Material, which is obviously defective, may be isolated and rejected by Weld County without regard to sampling sequence or location within a lot. Rejected material shall be removed at the Contractor’s expense.

Subsection 105.03 the two paragraphs following the Table 105-2 and starting with “If P is a negative number …” shall be deleted and replaced as follows:

If P is a negative number quantity, the material will be accepted as being in conformity. In cases where one or more elements show a positive P value, such positive values will be added, and the resulting sum will be used to determine the total P value. If the total P value is between 0 (zero) and 25, the Engineer may require correction or may accept the material at a reduced price. If P is greater than 25, the Engineer may:

(1) require complete removal and replacement with specification material at no additional cost to Weld County.

(2) require corrective action to bring the material into conformity at no additional cost to Weld County; or

(3) where the finished product is found to be capable of performing the intended purpose and the value of the finished product is not affected, permit the Contractor to leave the material in place with an appropriate price reduction to be based on engineering evaluation but not to be less than that which have occurred had a reduction been made where P=25.

If the P for aggregate gradation for items 206, 304, or the gradation of hydrated lime for item 403 is 0 (zero) or greater the reduction will apply to the contract price multiplied by the Multipliers (M) listed in Table 105-3:

Subsection 105.05, paragraph 3 shall be deleted and replaced with the following:

Materials will be sampled randomly and tested by the Department per subsection 106.05 and with the applicable procedures contained in CDOT’s Field Materials Manual. The approximate maximum quantity represented by each sample will be as set forth in subsection 106.05. Additional samples may be selected and tested as set forth in subsection 106.05 at the Engineer’s discretion.

Subsection 105.05(f)(2), paragraph 1 shall be deleted and replaced with the following:

(2) Where the finished product is found to be capable of performing the intended purpose and the value of the finished product is not affected, permit the Contractor to leave the material in place. If the material is permitted to remain in place, the PF for the process will not be greater than 0.75. The Engineer will be consulted before determining the material will be allowed to remain in place. The Engineer will also be consulted to assist in determining an appropriate pay factor.

Table 105-8, “W” and “V” Factors for Various Elements shall be deleted and replaced with the following:

Table 105-8 – “W” and “V” Factors for Various Elements

Subsection 105.09 shall be deleted and replaced with the following:

105.09 Coordination of Plans, Specifications, Supplemental Specifications, and Special Provisions. These specifications, the supplemental specifications, the plans, special provisions, and all supplementary documents are essential parts of the Contract, and a requirement occurring in one is as binding as though occurring in all. They are intended to be complementary and to describe and provide for a complete work.

In the event of a discrepancy, the order of precedence is as follows:
