Specifications include, but are not limited to: 1) Roads and Bridges (R&B). There are five (5) categories of roads in the Tactical Infrastructure (TI) Design Standard: FC-1, FC-2, FC-3, FC-4 and FC-5. Included within roads are also integrated culverts, low water crossings, guardrails, cattle guards, and bridges (including crossovers). The road system is not continuous and will require transporting equipment from site to site to complete maintenance activities. Access roads to TBI need inspection after any major natural events (such as heavy rainstorms, earthquakes, floods). a) At a minimum, the scope of work includes: • Regrading, or adding new material to FC-2 and FC-3 roads to facilitate traffic and provide proper drainage. • Performing spot surfacing, patching potholes, deep patching of asphalt surface, skin patching of asphalt surfaces, and patching asphalt berms. The work includes preparing the area, furnishing, hauling, and placing all necessary materials. • Removing and/or clearing vegetation so that roads are drivable. • Furnishing, hauling, and placing erosion resistant materials and protective materials for use on designated locations such as embankments and culvert inlets. • Returning road sections damaged by weather events or excessive use to a serviceable condition. • Adding binding and/or stabilizing agents to roads for dust suppression and road stabilization efforts. • Repairing or replacing damaged safety barriers, guardrails, signs, mirrors, etc. • Inspecting bridge (including crossovers) pavement/ surface material and guardrails. 2) Fence and Gates (F&G). There are three (3) categories of fencing: primary, secondary, and tertiary. There are two categories of gates: manual and automatic/mechanized. a) There are two general causes of damage to TBI assets leading to the need for corrective maintenance: environmental and manmade. Environmental damage to F&G refers to the forces of nature that will act upon the fencing and includes corrosion, erosion, water pooling, sand drifting, debris build-up, wind loading, temperature change (i.e., thermal expansion and contraction cycles that may create cracks) and ground shift and similar events. Manmade damage to F&G refers to vandalism, accidental damage, and cutting, burrowing below, climbing, prying/twisting, disassembly, ramming, ramping/bridging, pulling down, graffiti, cryogenic and fire/heating/burning and similar events. b) At a minimum, the scope of work includes: i) Fencing, including bollard wall – • Restore the structural integrity without significantly changing the design. • Correct damage caused by burrowing, water, and wind erosion. • Correct damage to fence foundations and mitigate erosion. • Moving and storing fence panels, as needed. • Abate graffiti. • Welding repairs shall be performed by a certified welder. • Painting. • Sand removal caused by blowing winds. ii) Gates – • Restore structural integrity to pre-existing state, are tamper proof, and do not significantly change the design. • Correct damage caused by rodents, vandalism, weather, ramming, burrowing, water, wind, and erosion. • Repairs to electrical or electronic components shall be performed by a certified and licensed electrician. • A certified welder shall perform welding repairs.
