This is considered to be within the general scope of the contract. An equitable adjustment for the temporary use of employees and equipment will be made under the CHANGES clause, FAR 52.243-4.

(b) Contractor's Responsibility for Fire Fighting. The Contractor, under the provisions of FAR 52.236-9, Protection of Existing Vegetation, Structures, Equipment, Utilities, and Improvements, shall immediately extinguish all fires on the work site other than those fires in use as a part of the work. The Contractor may be held liable for all damages and for all costs incurred by the Government for labor, subsistence, equipment, supplies, and transportation deemed necessary to control or suppress a fire set or caused by the Contractor or the Contractor's agents, subcontractors, or employees subject to the fire classifications listed in subsection (c).

(c) Fire Suppression Costs. The Contractor's obligations for cost of fire suppression vary according to three classifications of fires as follows:

(1) Operations Fire. An “operations fire” is a fire caused by the Contractor's operations other than a negligent fire. The Contractor agrees to reimburse the Forest Service for such cost for each operations fire, subject to a maximum dollar amount of ____________[Contracting Officer insert amount]. The cost of the Contractor's actions, supplies, and equipment expended or used on suppressing any such fire, or otherwise provided at the request of Forest Service, shall be credited toward such maximum. If the Contractor's actual cost exceeds the contractor's maximum obligation stated above, the Forest Service shall reimburse the contractor for the excess.

(2) Negligent Fire. A “negligent fire” is a fire caused by the negligence or fault of the Contractor's operations including, but not limited to, one caused by smoking by persons engaged in the Contractor's operations during the course of their employment, or during rest or lunch periods; or if the Contractor's failure to comply with requirements under this contract results in a fire starting or permits a fire to spread. Damages and the cost of suppressing negligent fires shall be borne by the Contractor.

(3) Other Fires on Contract Area. The Forest Service shall pay the Contractor, at firefighting rates common in the area or at prior agreed rates, for equipment or personnel furnished by the Contractor at the request of the Forest Service, on any fire on the contract area other than an operations fire or a negligent fire.

(d) Contractor's Responsibility for Notification in Case of Fire. The Contractor shall immediately notify the Government of any fires sighted on or in the vicinity of the work site.

(e) Performance by the Contractor. Where the Contractor's employees, agents, contractors, subcontractors, or their employees or agents perform the Contractor's operations in connection with fire responsibilities, the Contractor’s obligations shall be the same as if performance was by the Contractor.

(f) State Law. The Contractor shall not be relieved by the terms of this contract of any liability to the United States for fire suppression costs recovered in an action based on State law, except for such costs resulting from operations fires. Amounts due to the Contractor for firefighting expenditures on operations fires shall not be withheld pending settlement of any such claim or action based on State law.

Rig main superstructure components with permanent lifting devices to facilitate efficient installation and removal of these items with equipment common to logging or construction operations. Place lifting devices so as not to interfere with traffic utilizing the structure.

558.04 Design Drawings. When furnishing a prefabricated bridge superstructure, submit design drawings, calculations, and/or shop drawings sufficiently in advance of the start of fabrication to allow time for review by the CO and correction of any changes. Such time shall be proportional to the work, but not less than 21 days. Include plan, elevation, and section views of the modular bridge superstructure, dimensions of all components, welding and connection details, and general and specific notes regarding design and construction.

When Government-furnished prefabricated bridge superstructure components are specified, material lists, erection information, and manufacturer’s instructions will be furnished by the Government.

Construction

558.05 General. Perform excavation, backfill, and embankment work under Sections 203 and 206.

Dispose of all debris resulting from operations in accordance with Section 202.

Perform all construction of substructures, riprap, and signs under Sections 206, 206A, 251, 551, 552, 553A, 554, 555, 557, 564, 602, and 633, as applicable.

558.06 Performance. Provide 2 weeks’ notice prior to delivery and/or installation.

If the prefabricated superstructure is not installed immediately upon delivery to the project site, provide appropriate equipment and labor to unload and stack, support, and store all material at the delivery point. Support and stack all components to prevent damage. Furnish and install blocking such that all components are supported at least 12 inches above the ground.

Furnish all tools, devices, special equipment, and material needed for installation in well-marked watertight containers suitable for long-term, outdoor storage.

558.07 Contractor-Furnished Prefabricated Bridge Superstructure. As applicable, furnish the CO with the following items for approval prior to delivery of the bridge component:

(a) Supplier or inspection agency certification of wood species and grade of all timber and a conformance certificate for all sawn and glued laminated members.

(b) Certification by an approved inspection and testing agency of wood treatment, listing method of treatment, type of preservative, retention, and penetration.

Supplier certification is permitted if each piece is stamped or branded with a legible American Wood Preservers Bureau quality mark.

(c) Certification of structural steel, fasteners, and hardware.

(d) Certification of galvanizing process used.

(e) Steel fabricator certification that steel fabrication and quality control meet the requirements of the AISC Code of Standard Practice; and that all welding meets the requirements of ANSI/AASHTO/AWS D 1.5 Bridge Welding Code.

(f) A complete list of all bridge components, hardware, and fasteners.

(g) Complete erection instructions and drawings. Provide drawings that are black line, on a reproducible mylar media, on ANSI sheet size B or D.

As appropriate to the type of modular bridge, mark each major component of the bridge superstructure with the same serial number. Ensure that the marking is permanent and clearly visible on each component, both when stacked in storage and when erected on a bridge site.

When called for in the SPECIAL PROJECT SPECIFICATIONS, assemble each bridge superstructure prior to delivery to ensure proper fit-up of all components. Notify the CO of the assembly 2 weeks in advance so that inspection of the assembly can be arranged.

558.08 Government-Furnished Prefabricated Bridge Superstructure. When Government-furnished prefabricated bridge units are specified, transport all designated material from the storage site(s) designated in the SPECIAL PROJECT SPECIFICATIONS or SHOWN ON THE DRAWINGS to the bridge site, and install the superstructure complete and in place, including connection of all girders, diaphragms, railings, panels, transoms, and other elements.

Upon taking possession of the Government-furnished units at the storage site, assume all liability for damage resulting from handling, transporting, and/or erecting the units in place, until final acceptance of the project.

Measurement

558.09 Method. Use the method of measurement that is DESIGNATED IN THE
