625LIGHT POLE BASES

New Hampshire Department of Transportation Standard Specifications – 2016 Description

1.1This item shall consist of concrete light pole bases constructed at the locations and of the design shown on the plans or as

ordered. Materials

2.1Concrete shall be Class B conforming to Section 520.

2.2Granular backfill shall be gravel conforming to 209.2.1.2.

Construction Requirements

3.1Light pole bases shall be either precast or cast in place.

3.1.1 When precast bases are used, the hole shall be dug wide enough to allow for proper placement and compaction of the required backfill. The bases shall be placed on a prepared surface which shall provide a firm foundation. Where rock or unstable soil is encountered, the material shall be excavated 6 ” below the bottom of the base, and granular backfill placed and compacted in place of the excavated material. 3.1.2 When bases are to be cast in place, the holes shall be dug wide enough to allow the placement of concrete of the required diameter. Except when solid rock is encountered, the excavation shall be made to the full depth required on the plans. When solid rock is encountered, the bottom of the hole shall be at least 3 ft. from the top of the base and the concrete shall be firmly bonded to the rock with approved anchor rods. Forms will be required for the top of the light pole base only to a minimum distance of 12” below the finished grade of the ground at t he base. Sufficient excavation shall be made about that elevation to allow the proper placement of the forms and the proper placement and compaction of the required backfill.

3.2After the precast bases have been set, or after the removal of the forms for cast-in-place bases, granular backfill shall be

placed in the entire space outside the bases, to the level of the finished grade unless otherwise ordered. Backfill shall be made in layers not greater than 6”, with each layer thoroughly compacted. Method of Measurement

4.1Light pole bases will be measured by the number of units installed.

4.1.1 When more than 3 ft. of conduit, measured horizontally, is required to be installed from the center of the base, the first 3 ft. will be subsidiary. Basis of Payment

5.1The accepted quantities of light pole bases of the type required will be paid for at the Contract unit price for each complet e

in place. 5.1.1 There will be no separate payment for excavation and granular backfill. Pay items and units:

625.1Concrete Light Pole Bases, Type A Each

625.2Concrete Light Pole Bases, Type B Each

625.9Concrete Light Pole Bases, Special Type Each

Description

This work shall consist of sawing concrete pavement, bituminous pavement, or both, as shown on the plans or as ordered.

1.2This work shall consist of sawcutting grooves, routing the grooves and sealing with joint sealant at the end of the concrete

bridge deck at locations indicated on the plans or as ordered. Construction Requirements

Concrete pavement or bituminous pavement to be sawed shall be accurately marked before sawing.

3.1.1 Sawed bituminous pavement for bridge, points shall be marked on curbs at the end of the concrete bridge deck to aid in locating the end of the deck after pavement placement.

The equipment used to saw concrete or bituminous pavement shall be capable of sawing the pavement as shown on the plans

or as ordered and shall produce a substantially vertical and s ound face without deformation of the adjacent pavement. The use of methods other than sawing (i.e. cutting wheels, pavement breakers), which deform the pavement or leave an unsound face, will not be permitted.

3.3Contraction joints to be cut in concrete pavement shall be cut to the width and depth as shown on the plans and filled with

the type of filler shown on the plans. 3.3.1 Grooves to be cut in bridge pavement shall be cut and routed to the width and depth as shown on the plans and filled with the type of filler shown on the plans.

3.4Concrete pavement or bituminous pavement to be sawed in connection with laying pipes, roadway excavation, constructing

curb, and the like shall be sawed to a sufficient depth to permit breaking the pavement at the cut. 3.4.1 Where the pavement is found to consist of an overlay of bituminous pavement above a concrete slab, the cut shall be increased enough to score the underlying concrete so that the concrete can be broken in a reasonably uniform manner. Method of Measurement

Sawed pavement of the type specified will be measured by the linear foot.

4.2Sawed pavement for the purpose of installing culverts, storm drains, catch basins, drop inlets, manholes and conduit will not

be measured for payment. Basis of Payment

The accepted quantity of sawed pavement will be paid for at the Contract unit price per linear foot.

5.1.1 No separate payment will be made for filler.

5.2Sawed pavement for the purpose of installing culverts, storm drains, catch basins, drop inlets, manholes and conduit shall be

subsidiary to their respective items.

5.3Payment will be made under Item 628.3 only when bituminous concrete pavement and concrete pavement are sawed one

above the other.

Pay items and units:

628.1Sawed Concrete Pavement Linear Foot

628.2Sawed Bituminous Pavement Linear Foot

628.22Sawed Bituminous Pavement (Bridge) Linear Foot

628.3Sawed Pavement Linear Foot
