619.1Description.

This work consists of providing, constructing, reconstructing, or repairing stone or brick masonry.

619.2Materials.

A.Mortar Section 1047.6

B.Provide stone of the type and dimensions specified in the contract and in accordance with Section

1040. Provide stone free of iron content significant enough to cause rust-staining of the stone or materials below the stone.

1.For repair or reconstruction, use salvaged stone from the site or provide stone to match existing

stone types, colors, sizes, shapes, and patterns.

C.Provide brick in accordance with Section 1040.

1.For repair or reconstruction, provide brick to match existing stone types, colors, sizes, shapes,

and patterns as closely as possible.

D.Provide steel wall ties or dovetails hot-dipped galvanized in accordance with Section 1039.10 or

stainless steel in accordance with AASHTO M163.

619.3Construction.

A.Submittals.

1.Submit the masonry contractor qualifications verifying successful completion of at least 3 similar

projects within the last 5-years. Include a brief description of each project and the owner's contact person's name and current phone number for each project listed.

2.Submit samples of stone and brick for approval before starting work.

B.Place mortar to form a firm bond. Dispose of mortar not used within 30-minutes after adding

water. Do not re-temper mortar.

C.Placing Masonry

1.Do not perform any masonry work when the temperature is below 40 degrees F.

2.Lay the stone to the wall pattern shown in the contract. Wet the stone before laying in mortar.

Fill all joints with mortar and finish as work progresses. Make mortar joints 1-inch to 1 1/2- inches thick.

3.Lay bricks using the shove-joint method to bed the bricks into the mortar. Do not use buttered

or plastered joints. Arrange all brick headers and stretchers in order to bond the mass with alternate courses breaking joints. Fill all joints with mortar and finish as the work progresses. Make 1/4-inch to 1/2-inch thick joints. Do not use spalls or bats, except for shaping irregular openings or when unavoidable to finish out a course. If the engineer approves the use of spalls or bats, place full bricks at the corners and place bats in the interior of the course.

D.After constructing the masonry, clean the entire area of all efflorescence, mortar, scars, or spots

to present a natural color. Clean the area with water. Treat with a solution of 1 percent hydrochloric acid and then wash again with water a final time. When cleaning stone masonry with

the solution, take care to notice any deteriorating reaction. If a reaction is noticed, stop using the solution, wash the treated area immediately and clean the stone masonry to present the natural color.

E.Before pointing existing masonry, rake all deteriorated and loose mortar from the joints. Clean the

joints with water under high pressure. Remove excess water from the cavity with air under high pressure. Wet joints before applying the mortar. Mix and place mortar in accordance with Section 619.3.B. Use only mortar that matches the color of the existing mortar. In hot or dry weather, shield pointing work from the sun and keep wet for a period of 3-days after completion.

F.Exercise care when handling existing masonry planned for reconstruction. Avoid dropping,

breaking or scarring the stones. Reuse exposed surfaces of existing stone in the reconstructed structure, except as directed by the engineer. Ensure that the reconstruction results in a structure that resembles the original and adjacent structures in overall appearance.

619.4Method of Measurement.

A.The Department will measure the quantity of:

1.Stone masonry by the square foot placed and accepted.

2.Brick masonry by the square foot placed and accepted.

3.Pointing masonry by the linear feet of joints pointed and accepted.

4.Reconstructing existing stone masonry by the square foot or cubic foot of existing stone

masonry reconstructed and accepted.

5.Reconstructing existing brick masonry by the square foot or cubic foot of existing brick masonry

reconstructed and accepted.

619.5Basis of Payment.

A.Price and payment for stone or brick masonry will constitute full compensation for:

1.Submittals;

2.samples;

3.providing;

4.placing;

5.cleaning stone or brick masonry; and

6.disposal of surplus materials.

B.Price and payment for pointing existing masonry will constitute full compensation for providing all

materials and pointing the joints as described in this specification.

C.Price and payment for reconstructing stone or brick masonry will constitute full compensation for

removing and stockpiling existing stone or brick, disposing of unsuitable materials, and providing, placing, and cleaning stone or brick masonry.

D.The Department will pay for excavating and backfilling in accordance with Section 207.
