CONSTRUCTION GENERAL

PART 1 GENERAL

1.1 SCOPE

The work covered in this section is outlined as a statement of construction requirements common to all the work. Specific requirements for materials and installations are provided under the Technical Sections herewith. No claims for extras shall be made on account of items presumed to have been omitted from this section.

1.2 CONSTRUCTION RIGHT-OF-WAY

The Contractor will be assigned working areas or working right-of-way limits for use in the prosecution of work under this contract, subject to the SECTION 00 72 00, GENERAL CONDITIONS (CONTRACT CLAUSES) clause entitled "Operations and Storage Areas."

1.3 PROTECTION OF EXISTING FACILITIES AND WORKS

The Contractor shall be responsible for the protection of the work area from damage and upon completion of the work shall leave existing works in a condition equal to that which existed when the work started. All work, storage of materials, and construction plant shall be kept within the limits of the areas assigned. Prior to construction operations, the Contractor shall confer with the Contracting Officer's representative to determine the proximity of any possible under-ground obstructions, pipe or equipment which could be damaged as a result of construction operations.

Existing utility lines that are shown on the drawings or the locations are otherwise made known to the Contractor shall be protected from damage, and if damaged, shall be repaired by the Contractor at no additional expense to the Government. In the event that the Contractor damages any existing utility lines that are not shown or the locations of which have not been made known to the Contractor, the Contractor shall immediately notify the Contracting Officer. The Contracting Officer will review the information and discuss with the Contractor how to proceed. The Contractor will be responsible for the protection of structures from any structural damage during the construction operations. Roads and surfaces shall be protected from damage by the work or if damaged shall be repaired with equal materials at no additional expense to the Government. At all times the plant and work areas shall be kept in a condition conducive to safety of workmen and the public and neat in appearance. Waste or surplus materials shall not be allowed to accumulate in the construction areas.

1.3.1 Interruption of Electric Power

If it is necessary to cut off power in transmission lines that pass through construction areas, it shall be the Contractor's responsibility to make the necessary arrangements with the owner of the powerline, and the Contractor shall pay all costs therefore.

SECTION 01 12 00 Page 2

1.4 CARE OF WATER

Full responsibility for care of water shall be borne by the Contractor until completion of work under this contract. The Contractor shall provide the materials and equipment and perform all work necessary to facilitate construction and to protect the work from damage by water. The Contractor shall make the needed investigations and determinations of conditions, both existing and anticipated concerning care of water. Plans for care of water are subject to approval by the Contracting Officer prior to construction. Facilities shall be removed upon completion of the work.

1.5 DISPOSITION OF CONSTRUCTION FACILITIES

All buildings and facilities constructed by the Contractor shall be maintained in a satisfactory condition with strict observance of the rules of sanitation, safety and order as may be established by the Contracting Officer. Prior to final payment under the contract, all buildings and facilities constructed by the Contractor for the Contractor's use shall be removed from the site by the Contractor.

1.6 ACCESS ROADS AND HAUL ROADS

1.6.1 Access Roads

Access roads as required for the prosecution of the work shall be maintained (including sprinkling for dust control, safety personnel, and traffic control) within the work areas assigned to the Contractor.

Consideration shall be given to the avoidance of interference with others, safety and frequency of traffic, subject to review and approval prior to construction. Access road areas shall be restored to their original or suitable condition upon completion of this contract. The Contractor shall be responsible for repair of damage to existing roads caused by the Contractor's operation.

1.7 PUBLIC ROADS

1.7.1 State and Federal Highways

Where the Contractor hauls across or on State or Federal highways, the Contractor shall enter into all agreements with the State Highway Commission and shall comply with any restrictions they may impose relative to load limits, care of traffic and cleanup. Such agreements shall clearly relieve the Government of any responsibility for damages resulting from hauling across or on State highways. Copies of such agreements shall be furnished to the Contracting Officer before the Contractor begins hauling on these highways.

1.7.2 State and Local Public Roads

(a) Load Limits:

The South Dakota Department of Transportation and local County Road Commissions restrict the load weights of haul vehicles using highways and county roads during the spring thaw period. The load restrictions are usually imposed from 1 April through June depending on actual weather conditions.

SECTION 01 12 00 Page 3

(b) Hauling Regulations:

Prior to start of hauling operations on public roads, the Contractor shall furnish evidence to the Contracting Officer that an agreement has been consummated with State and County officials on the use of public roads and bridges. Such agreements shall clearly relieve the Government of any responsibility for damage resulting from hauling across or on these roads.

1.7.3 City Streets

Where the Contractor intends to cross or to use city streets for haul roads the Contractor shall enter into an agreement with the City and shall comply with any restrictions the City may impose relative to load limits, care of traffic and cleanup. Such agreements shall clearly relieve the Government of any responsibility for damage resulting from hauling across or on these highways. A copy of all such agreements shall be furnished the Contracting Officer before the Contractor begins hauling in city streets.

1.8 COOPERATION WITH OTHER CONTRACTORS

The Contractor shall cooperate and coordinate work with that of others working in the area during the life of this contract. The Contractor shall coordinate work with others to avoid undue interference and shall conduct operations, other than approved required access, within the limits of the assigned construction area or construction right-of-way limits.

The Contractor shall cooperate with others as necessary in the interest of timely completion of all work and in the event of disagreement the decision of the Contracting Officer shall be final.

1.9 COORDINATION AND OUTAGES

The Contractor's employees shall not open, close or tamper with switches, valves or control devices for existing installed equipment. Only Government operating personnel will be authorized to open or close existing switches, valves and control devices to enable the Contractor to make connections or modifications to existing equipment. Work shall be coordinated and scheduled to reduce the "Outage" time of operating equipment or systems to a minimum. Work in the proximity of exposed energized equipment such as in the switchyard or work involving connections to existing energized or operating equipment or systems shall perform only under the Safe Clearance Procedures. The Contractor will be instructed by the Contracting Officer in the proper procedure for requesting clearances. Only qualified supervisory personnel will be permitted to request clearances. Request for "Outage" shall be made by the Contractor to the Contracting Officer in each instance and in sufficient time to permit adjusting power plant operations, and to coordinate outages with the dispatching agency. Scheduling of "Outage" will be subject to the approval of the Contracting Officer.

*Am-1 The contractor will be required to coordinate outages 30 days prior of the date the required outage. For this project the contractor will need to perform the work during low energy demand periods. The contract will need to perform the work 01 march through 31 May or 01 September through 30 November.

SECTION 01 12 00 Page 4

The contractor will be required to coordinate outages 30 days prior of the date the required outage. Multiple outages will be required to complete the work based on availability of materials at the time of award. The current outage schedule will pertain to one bus at a time to replace the disconnects associated with each section. The outage periods are currently scheduled for 2/26/2024 through 5/23/2024, 9/3/2024 through 11/28/2024, and 3/3/2025 through 5/29/2025. Typically, the clearance is placed on the first day of the outage and the contractor can expect to receive access to the affected area on the second day after signing and locking onto the clearance. The preferred sequence will be 230kv bus sections 5,3,1 and then the 115kv bus. The 230kv bus and 115kv bus sections cannot be de-energized at the same time. The sequence of work is subject to change if there is other work ongoing at the project concurrently. It is expected that the auxiliary bus will be de-energized while work is happening in that yard to allow switches on both the main and aux bus to be replaced.
