owner will pay the Contractor for work for the new permanent driveway and payment

will be made before the work begins. This work will be considered a separate contract

between the property owner and the Contractor and DPW’s involvement will consist

of inspection duties only.

2.8 Concrete Sidewalk

The concrete sidewalk shall be screeded to a true surface, free from depressions and other

irregularities and shall be floated with a magnesium alloy float. After it has taken its original set,

it shall be floated again with a magnesium alloy float to produce a hard smooth finish free from

water. The surface shall be given a light broom finish acceptable to the Project Manager.

11

Should the sidewalk be too wide to properly finish from each side, it shall be bridged so that the

concrete will not be disturbed after it is screeded.

Wherever full width sidewalk is placed from the curb to the Property line, the sidewalk shall be

placed in alternate blocks. The size of these blocks shall be determined by the Inspector. Every

effort shall be made to maintain color and texture.

Entrance (Carriage) walks connecting with the City sidewalk that have to be cut off, shall be cut

with a concrete saw and all exposed ends faced up with concrete, leaving a neat appearing surface.

The cost of this work is to be included in the price bid for concrete sidewalk.

and sidewalks that replace existing concrete sidewalks shall be prepared by the removal and

satisfactory disposal of all unsuitable material above the normal sub-grade. All unsuitable material

shall include existing concrete sidewalk and existing brick sidewalk. Any material removed

above normal sub-grade shall be disposed of by the contractor in an area approved by the Project

Manager. No tree roots encountered above normal sub-grade will be cut unless approved by the

City Arborist.

Sub-grade shall be compacted to a theoretical density of 95% at optimum moisture (Standard

Proctor), and shall be graded off to a surface that will not vary more than ½‖ at any one point

from normal sub-grade. Wherever tree roots prevent excavation of existing ground surface to

normal sub-grade, sub-grade will be determined by the construction Inspector in the field.

Measurement and Payment

Payment for all new concrete sidewalk and for removal and replacement of existing walk with

new concrete sidewalk shall be made at the contract unit price bid per square yard for “4”

concrete sidewalk, complete in place (remove and replace existing sidewalk).

Cobblestone or brick shall be place on a dry mortar bed. Level the area under the bricks. Smooth

the sanded area under the sidewalk and add or remove more sand if necessary to bring the area level

with the rest of the bricks.

12

Tamp down the sand. Use one of the bricks to tamp down the sand until it is hard and flat. If there

are still uneven spots, add or remove more sand and tamp it down again.

Fill in the hole with bricks. Use the old bricks where possible, and replace any broken bricks with

identically measured new ones. Keep to the existing pattern. You should have no trouble simply

pushing the bricks into place until you reach the final brick. This likely will be a tight squeeze,

and you may need to tap it into place with the rubber mallet.

Fill in the areas around the bricks with sand. Sprinkle the sand over the joints in the bricks and

then push it in by hand. Once you have forced as much sand as possible into the joints, you can

sweep off the walkway. The sand will hold the brick repair in place, and your brick sidewalk

should look as good--or better--than new.

If the inspector determines that concrete bedding is required, the concrete shall be paid as a separate

pay item based on depth.

2.10 New Brick Sidewalk on Concrete Base

Brands of Brick – Brick for new sidewalks and sidewalks that replace existing concrete sidewalks
