BID NO # B2500017 Page 5 5 Schedule B - Scope of Work Project Overview The Board of County Commissioners of Weld County, Colorado, by and through its Controller (collectively referred to herein as "Weld County") is soliciting proposals for erosion control and revegetation services to supplement Weld County's needs for the year 2025. Erosion control and revegetation services typically consist of projects of various sizes at several locations which will require project management meetings (both onsite and in office), temporary erosion control measure installation/maintenance, sediment removal from culverts and washouts, and stabilization methods such as seeding and mulching. Other duties may be negotiated as necessary. Upcoming projects will likely include road, bridge, drainage, and gravel pit projects. The Contractor services will be requested by the County on an as -needed basis by issuing individual Internal Accounting forms (lAs) (aka "work order"). For each IA, the County will provide basic project information so the Contractor can prepare a detailed scope of work and cost estimate. The IA will be signed by both Weld County and the Contractor. This is an on -call construction services agreement. There is no guarantee that the County will need or utilize the services of the Contractor in any given year. There is no retainer paid by the County. The Contractor understands and agrees that there are no guarantees of specific tasks or quantities of services associated with the construction services agreement. The Contractor may or may not perform the erosion control and seeding services as circumstances require. Furthermore, the County is in no way obligated to utilize the Contractor in every applicable situation encountered. This is a multiple award contact. The County may award up to two contracts based on the lowest bids received. If multiple contractors are selected, the budgeted amount will be divided among the contractors as determined by Public Works. The construction services agreement shall commence on the date the Agreement is signed by the Board of County Commissioners and shall continue in full force until December 31, 2024. At the option of the County, the agreement may be extended for up to two additional one-year periods beginning on January 1 and ending on December 31. If the agreement is renewed, the Contractor will have the opportunity to revise the contract fee schedule in accordance with the "Engineering News -Record (ENR) Cost Index" for Denver. This agreement may be used at the option of other Weld County Departments. Method of Procurement Invitation for Bid (IFB): is a procurement method often referred to as a sealed bid solicitation.

Unless otherwise specified, longitudinal measurements for area computations will be made horizontally, and deductions will not be made for individual structures having an area of 9 square feet or less. Unless otherwise specified, transverse measurements for area computations will be the neat dimensions shown on the plans or as ordered in writing by the Engineer. Structures will be measured according to neat lines shown on the plans or as altered to fit field conditions. Items which are measured by linear foot, such as pipe culverts, guardrail, underdrains, etc., will be measured parallel to the base or foundation upon which the structures are placed, unless otherwise shown on the plans. In computing volumes of excavation and embankment, the average end area method or the method incorporated into the Department's computer earthwork program will be used. The term "gauge," when used in connection with the measurement of plates, will mean the U.S. Standard Gage. When the term "gauge" refers to the measurement of wire, it will mean the wire gage specified in ASTM A510. The term "ton" will mean the short ton consisting of 2,000 pounds avoirdupois.

hours, a pnce reduction on the material in question will occur as follows O less than 24 hours = 2% O 25 - 48 hours = 5% O 48 hours to 72 hours = 25% O Greater than 72 hours = 100% October 1, 2024 4 Revision of Section 109 — Measurement and Payment Weighers using hopper scales solely for batching matenals not measured and paid for by weight need not be certified The Engineer will randomly venfy the accuracy of the certified weigher on every project where the weights are manually entered on the scale ticket This verification will consist of at least one comparison check on the project Additional verification checks may be required as determined by the Engineer The Engineer w II randomly select a loaded truck after the truck has been issued a scale ticket by the certified weigher The loaded truck will then be reweighed, in the presence of the Engineer, on the same scale and the weight compared w th the weight on the scale ticket Reweighed loads shall be within the tolerance of 200 pounds plus or minus The Engineer will also verify the accuracy of computerized scales Computerized scales are scales that automatically print weights on the scale ticket This verification will consist of at least one comparison check when the project requires more' than 2,500 tons of material to be weighed This comparison check shall be made by reweighing a loaded vehicle The Contractor shall either provide a second certified scale or select a second certified scale in the vicinity to be used for the comparison check, Comparison checks shall be performed using the following procedures I (1) Hopper Scale A loaded truck will be randomly selected by the Engineer The loaded truck shall be weighed on a certified platform scale to record the gross weight The truck shall be unloaded and weighed again on the same scale to record the tare weight The tare weight shall be subtracted from the gross weight and compared against the net weight recorded on the scale ticket (2) Platform Scales The Engineer will randomly select a loaded truck The loaded truck shall be eweighed on a second certified scale and the gross weight shall be compared against the gross weight on the first scale ticket Should a comparison check reveal a weight difference of more than one percent, a second comparison check shall be performed immediately If the weight differences of both comparison checks exceed the one percent limit, the Contractor shall immediately stop weighing and the scale shall be recertified and resealed at the Contractor's expense The necessary adjustments as indicated by the recertification will be made to all scale tickets issued since the last certification or on the entire project, whichever occurred later, unless the Contractor demonstrates to the satisfaction of the Engineer that the defect in the scale was present for a lesser penod of time - if it is necessary to recertify a scale, and more than 2,500 tons of matenal remain to be weighed, another scale comparison check shall be made All comparison checks shall be made at the Contractor's expense October 1, 2024 5 Revision of Section 109 — Measurement and Payment Matenals to be measured by volume in

the Engineer determines there is reason to believe the meters are not accurate within the allowable tolerance If water meter accuracy is found acceptable, the cost involved in checking the water meter shall be at the Department's expense If the water meter accuracy is found unsatisfactory, the cost involved in checking the water meter shall be at the Contractor's expense For those matenals specified to be measured by the cubic yard, an acceptable method of computing volumes of excavation is to determine a weight to volume factor and convert weight to volumes by means of the factor Colorado Procedure 80 as descnbed in the CDOT Field Matenals Manual shall determine the weight to volume factor The number of tests used to determine the matenal weight to volume factor will be determined by the Engineer The locations where the tests are taken shall be at those locations specified in the "Method of Measurement" for the particular bid item, i e , Unclassified Excavation - in its onginal position Embankment Material - in its final compacted position, etc Asphalt materials will be measured by the gallon or ton Volumes will be measured at 60°F or will be corrected to the volume at 60°F using ASTM D1250 for asphalts or ASTM D633 for tars Net certified scale weight or weight based on certified volumes in the case of rail shipments will be used as a basis of measurement,
