1.2 Relocation . Relocate existing large roadside sign assemblies and furnish and fabricate materials as
required.
1.3 Removal . Remove existing large roadside sign assemblies.
1.4 Replacement . Replace existing large roadside sign assemblies.
Article 2 — Materials
Furnish all materials unless otherwise shown on the plans. Furnish only new materials. Furnish and fabricate materials in accordance with the following Items and as shown on the plans . Item 416, “Drilled Shaft Foundations” Item 421, “Hydraulic Cement Concrete” Item 440, “Reinforcement for Concrete” Item 441, “Steel Structures” Item 442, “Metal for Structures” Item 445, “Galvanizing” Use material for perforated fuse plates that does not exceed the ultimate tensile strength shown on the plans. Use galvanized steel, stainless steel, dichromate sealed aluminum, or other materials shown on the plans for bolts, nuts, washers, lock washers, screws, and other sign assembly ha rdware. When dissimilar metals are used, select or insulate the metals to prevent corrosion.
Article 3 — Construction
Construct foundations for large roadside sign supports and assemblies in accordance with Item 416 and as shown on the plans. Plumb sign supports. Do not spring or rake posts to secure proper alignment. Use established safety practices when working near underground or overhead utilities. Consult with the appropriate utility company before beginning work.
3.1 Fabrication . Fabricate in accordance with Item 441. Ensure all components fit properly.
Verify the length of each post for each sign before fabrication to meet field conditions and sign- mounting heights shown on the plans. Obtain approval for any necessary field fabrication or adjustments. Hot-dip galvanize fabricated parts in accordance with Item 445. Punch or drill any holes in steel parts or members before galvanizing. Repair galvanizing for any steel part or member on which the galvanizing has been damaged during assembly, transit, or erection, or for any steel part or member welded when permitted, after galvanizing. Make all galvanizing repairs in accordance with Section 445.3. 4., “Repairs.”
3.2 Installation . Locate sign supports as shown on the plans, unless directed to shift the sign supports within
design guidelines to secure a more desirable location or avoid conflict with utilities and underground appurtenances. Stake the sign support locations for verification by the Engineer. 888 Install stub posts of the type and at the spacing, orientation, and projection shown on the plans. Secure the stub posts rigidly in position during concrete placement. Connect the upper post sections to the stub post sections as shown on the plans. Ensure a flat washer is positioned on top of the bolt keeper plates between the upper and lower slip base sections, and a flat washer is positioned under the head and nut of each connection bolt. Torque connection bolts as shown on the plans. Attach signs to supports as shown on the plans and in accordance with pertinent Items.
3.3 Relocation . Reuse the existing supports and shorten them as required, unless otherwise shown on the
plans. Furnish and install new breakaway stub posts in new foundations for relocated sign assemblies. Erect the supports on the new stub posts and attach the signs to the supports as shown on the plans and in accordance with pertinent Items . Unless otherwise shown on the plans, remove abandoned concrete foundations and replace surfacing in accordance with Section 647.3.4., “Removal.”
3.4 Removal . Remove abandoned concrete foundations , including steel , to 2 ft. below finish ed grade, unless
otherwise shown on the plans. Cut off and remove steel protruding from the remaining concrete. Backfill the remaining hole with material equal in composition and density to the surrounding area. Replace any surfacing with like material to equivalent condition.
3.5 Replacemen t. Replace sign and sign supports as shown on the plans. Furnish and install new sign steel
supports, fuse plates, and sign with hardware. Erect the assembly on top of existing foundation stub and attach signs to the supports in conformance with the plans and pertinent I tems .
3.6 Handling and Storage . Handle and store existing signs or portions of signs removed so they are not
damaged. Prevent any damage to the various sign assembly components. Replace any portion of the sign damaged by the Contractor designated for reuse or salvage, including messages removed. Stockpile all removed sign components that will be reused or become the property of the Department at designated locations. Accept ownership of unsalvageable materials and dispose of them in conformance w ith federal, state, and local regulations.
3.7 Cleaning . Wash the entire sign after installation using a biodegradable cleaning solution acceptable to the
sign face material manufacturers to remove dirt, grease, oil smears, streaks, finger marks, and other for eign materials.
Article 4 — Measurement
Installation will be measured by the pound of large roadside sign support steel. Sign assemblies relocated, removed, or replaced will be measured by each large roadside sign assembly . This is a plans quantity measurement Item. The quantity to be paid is the quantity shown in the proposal, unless modified by Article 9.2., “Plans Quantity Measurement.” Additional measurements or calculations will be made if adjustments of quantities are required.
Article 5 — Payment
The work performed and materials furnished in accordance with this Item and measured as provided under “Measurement” will be paid for at the unit price bid for “Install Large Roadside Sign Supports” of the type specified, “Remove Large Roadside Sign Assemblies,” “Relocate Large Roadside Sign Assemblies ,” or “Replace Large Roadside Sign Assemblies.” 889 New drilled shaft foundations will be paid for in accordance with Item 416. New signs will be paid for in accordance with Item 636, “Signs.”
