All key personnel from both parties shall be in attendance at this conference, as well as utility company representatives, and any other outside individuals that may play a role in the construction process. The Contractor and the County will exchange letters at this conference, each naming their primary and secondary contacts who will be the authority and be designated to speak for each party in case of any oral directives or agreements.

The following is a tentative preconstruction conference agenda:

• Authority and Responsibilities

• Erosion Control Plan

• Traffic Control Plan and Supervisors, 24-hour Traffic Control

• Project Safety Plan

• List of Subcontractors and Suppliers

• Identification of Key Personnel of all Parties

• Construction Project Schedule

• Temporary Facilities (office)

• Submittals

• Sampling and Testing of Materials

• Project Inspection

• Contract Administration

• Project Administration

• Coordination and Protection of Utilities

• Coordination and Protection of Adjacent Private Property (maintain driveway access, etc.)

• Off-Site Disposal Plans and Haul Routes

• Construction Water and Dust Abatement

• Construction Surveying

• Final Site Restoration

• Record Drawings (to be provided to the County upon project completion)

Weekly Meeting. A weekly meeting will be scheduled on the Project Site with the Contractor’s staff, County’s staff, and the utility companies’ representatives. The meeting will focus on schedule updates, problem solving to actively and aggressively maintain the project schedule, progress reports, changes to the Work, utility interferences, safety of public, requests for payment, and general project information.

Project Inspection

The County’s Inspectors will act as observers and field representatives for the project. The project will be inspected using the standards listed in the contract documents’ supplementary conditions and construction drawings.

The Contractor will be responsible for constructing all phases of the work under these provisions. It will be the Contractor's responsibility to coordinate his work with subcontractors, utility companies, and the general public. The County will have the authority to question the

Contractors’ means and methods of construction as they apply to the requirements of the plans and specifications and the County reserves the right to ask the Contractor to perform a test section before proceeding with their operations. If it can be clearly established that the use of a certain piece of equipment to do a specified job will, in all probability, result in inferior construction quality, it is within the authority of the County to require that appropriate changes be made.

The County shall provide a Quality Control program through a Licensed Materials Testing Lab.

The Contractor shall notify the County twenty-four (24) hours in advance of any inspection and testing required as part of the contract documents. Work that has been completed, or partially completed, and has been covered up by the Contractor prior to inspection or testing, shall be subject to possible removal and replacement and may require additional testing, all at the expense of the Contractor. Failure of a County Inspector to observe a deficiency does not relieve the Contractor of obligation for performance. Extra inspections required as the result of the

Contractor’s deficiencies will be paid for by the Contractor at the County Inspector’s current rate. The Contractor shall pass on all test data to the County and shall notify the County’s testing lab of tests at the direction of the County Inspector.

The Contractor will be responsible for testing of asphalt per Section 106.05 of the CDOT

Standard Specifications for Road and Bridge Construction.

Inspection procedures:

The Inspector will require a delivery ticket for each load of concrete, gravel, asphalt or any other material bid item that will require weighted measurements delivered to the project. All of the tickets will be collected by the Contractor's foreman and copies given to the Inspector at the end of each work day. If these tickets are not turned in by the end of the work day, there will be a

$150 credit given to the County and assessed at the next pay voucher. No payment will be made for tickets turned in later than the end of the next day after the material delivery. It will be the

Contractor’s responsibility to ensure that the Inspector receives the delivery tickets. The

Contractor will compile all of the tickets into a Material Weight Sheet Log and review it with the inspector prior to formalizing each Progress Payment for submittal as an invoice. Any rejected loads or non-compliance areas will be noted on the Material Weight Sheet Log.

Progress Payment (Quantities)

A Material Weight Sheet Log and supporting delivery tickets are to be submitted with each payment request. With each Progress Payment it will be the Contractor's responsibility to provide concise, accurate, and complete quantity information. Failure to provide such information may result in delayed payment or rejection until proper information can be submitted. The County’s Project Manager/Engineer reserves the right to question in-place quantities, partial payments and other items deemed necessary before each Progress Payment is approved. It will be the Contractor's responsibility to measure each work item for in-place quantities and the County’s responsibility to independently check and verify the Contractor’s quantities. The Contractor and the County’s Inspector will agree on each monthly Progress

Payment quantity before any Progress Payment is processed.

Submittal Requirements (Note: This reference pertains to the Contractor’s obligations post-award; not to be confused with Submittal Requirements noted elsewhere in this IFB for the bid submittal.)

The word "Submittals" shall be interpreted to include drawings, data, manuals, certifications, tests reports, curves, samples, color chips or charts, brochures, acceptance letters, and any other items furnished by the Contractor for acceptance, approval, review, informational or other purposes.

The Contractor shall furnish all materials and perform all work required for furnishing submittals to the County’s Project Manager/Engineer in accordance with the Contract Documents and

CDOT Standard Specifications for Road and Bridge Construction, 2022 edition. A list of submittals for this project will be available after contract award. The submittals shall be submitted in a timely manner to allow for County review prior to the work. Insufficient lead time for the County review process will not relieve the Contractor’s obligations to construct the work in accordance to the Contract Time and maintain the quality level as prescribed by the

Contract Documents, Drawings, and Specifications, nor will it obligate the County for damages due to delays resulting from untimely submittals.

Project Safety Plan

The Project Safety Plan must address the Contractor’s plan for employee safety on the job. The

Contractor may adopt an existing set of standards, such as the Bureau of Reclamation’s or other agency’s, with an umbrella-type plan for construction work. The Contractor must address safety at the various work stations and working areas expected to be encountered for this particular project. Personal safety equipment, vehicle and equipment safety procedures, and mixing/crushing plant provisions for creating a safe work site should be included in the plan.

The plan should be submitted prior to the beginning of construction.

Traffic Coordination/Detour Plan

This submittal should address a complete plan for traffic control for the various phases of the project. It should be formulated after reading and understanding the requirements of these specifications. The plan should include a traffic control plan of the detour, number of traffic personnel, equipment, and the methodology for traffic control. The Contractor shall determine the 24-hour traffic control method, detail the method to be used and be prepared to defend its selection. The County reserves the right to adjust or reject the 24-hour traffic control method if the safety of the public is not adequately addressed. Vehicle delays or stopping time should not be more than twenty (20) minutes total through the project. No stopping delays of more than ten

(10) minutes are allowed from 7:00 to 8:00 AM and from 4:30 to 5:30 PM. The Contractor shall provide two warning signs outside the project alerting the traveling public to potential delays of up to twenty (20) minutes, location to be determined in on-site by the County.

Protection of Utilities

The Contractor shall comply with Article 1.5 of Title 9, CRS ("Excavation Requirements") when excavation or grading is planned in the area of underground utility facilities. The Contractor shall notify all affected utilities at least two (2) business days, not including the day of notification, prior to commencing such operations. The Contractor shall contact the Utility

Notification Center of Colorado (UNCC) at (8-1-1) or 1-800-922-1987 to have locations of

UNCC registered lines marked by member companies. All other underground facilities shall be located by contacting the respective company. Utility service laterals shall also be located prior to beginning excavating or grading.

The location of utility facilities as shown on the plan and profile sheets if provided, and herein described, were obtained from the best available information. All costs incidental to the foregoing requirements will not be paid for separately but shall be included in the work.

In subsection 203.02(c), This work also consists of removing unsuitable material, where pumping is occurring and where soft suspect foundation material is present, as described in Subsection 203.02 from below subgrade elevation in native soils or from below the natural, existing ground line in embankment sections, hauling the material to an acceptable location off site and replacing the removed material with geotextile and either

Class 2 ABC or crushed screened rock.

Subsection 203.05 (c) Delete and replace with the following:

The depth of excavation for muck excavation will normally be 18 inches, unless other conditions require a deeper excavation, which shall be a collaborative decision between the Engineer and Contractor. The removed material will be considered completely unsuitable for reuse anywhere in the project due to its gradation, clay content, or moisture content and the excavated material shall be taken off the project for disposal. If the

Contractor feels that the removed material has some potential value for a specific use within the project, the Contractor may submit a plan for its specific use within the project. For Contractor’s estimation purposes, the material shall be assumed to be completely removed from the project. This removed material has not been included in the calculations for determining quantities for cut, fill, and borrow on the project. The quantity for Muck Excavation is an estimate, based on the Owner’s experience with similar projects.

No ABC material may be placed on subgrade in a section until proof rolling has been approved and witnessed by both the Engineer’s representatives and the Contractor. After the subgrade has been compacted, tested and found to meet specifications, the entire subgrade shall be proof rolled. Subgrade which is pumping or deformed must be reworked, replaced or otherwise modified to form a smooth, stable, non-yielding base for subsequent paving courses. The Engineer shall be notified at least 24 hours before final proof-rolling.

The excavated area shall be backfilled with three inches of class 2 ABC or crushed screened rock, then the geotextile installed, and compacted to the top of subgrade with

Class 2 ABC or crushed screened rock. Geogrid or geotextile reinforcement shall always be installed. Geogrid shall comply with section 506. Geotextile shall comply with

Section 420. Sufficient amounts of geotextile required for any subgrade problems shall be stockpiled on site at all times.

Maintenance and Protection of Traffic will not be measured but will be paid for on a

Lump Sum Basis. Payments will be made based on a percentage of total project bid items completed, exclusive of Mobilization.
