PREPARATION Establish extent of grading and excavation by area and elevation. Designate and identify datum elevation and project engineering reference points. Set required lines, levels and elevations. Do not cover or enclose work of this Section before obtaining required inspections, tests, approvals, and location recording.

3.02

EXISTING UTILITIES Before starting grading and excavation, establish the location and extent of underground utilities in the work area. Exercise care to protect existing utilities during earthwork operations. Perform excavation work near utilities by hand and provide necessary shoring, sheeting, and supports as the work progresses. Maintain, protect, relocate, or extend, as required, existing utility lines to remain which pass through the work area. Protect active utility services uncovered by excavation. Notify respective utility companies of damage caused to active utilities immediately. Remove abandoned utility service lines from areas of excavation. Cap, plug, or seal abandoned lines at source of connection and identify termination points at grade level with markers. Accurately locate and record abandoned and active utility lines rerouted or extended on project record documents.

3.03

SITE GRADING B GENERAL Perform grading within contract limits, including adjacent transition areas, to new elevations, levels, profiles, and contours indicated. Provide uniform levels and slopes between new elevations and existing grades. Obtain approval of scarified subgrade surfaces by City's Representative prior to filling operations. Scarify, dry, and compact soft and wet areas; remove and replace unsuitable subgrade materials with an approved fill material. Take corrective measures before placing fill materials. Thoroughly scarify existing soil surface to a depth of 10" and as shown on the Soils Report and verify scarification with City's Representative prior to placing fill material in mounded areas. Spread approved fill material uniformly in layers not greater than 12" of loose thickness over entire fill zones of planting areas. 1. Lift thickness requirements may be modified by City=s Representative to suit equipment and materials or other conditions when required to assure satisfactory compaction.

Earthwork

02310-5

2. Place and compact each layer of fill before placing additional fill material. Repeat filling until proposed grade, profile or contour is attained. 3. Suspend fill operations when satisfactory results cannot be obtained because of environmental or other unsatisfactory site conditions. Do not use over-saturated fill materials. Do not place fill material on over-saturated subgrade surface. 4. Grade surfaces to assure positive drainage and to prevent ponding and pockets of surface drainage. Install drainage swales as indicated on the Drawings. 5. Protect finish graded areas from traffic and erosion. Keep free of trash and debris. Repair and reestablish grades in settled, eroded and damaged areas. If, in the opinion of the City, the completed site grading does not reflect the Contract Documents, an independent surveyor may be hired to verify the grades. If the grades are correct, the City will pay for the survey. If the grades are incorrect, the cost of the survey will be deducted from the Contract price. 3.04

BACKFILLING / FILLING FOR PAVING & WALLS Before filling, remove debris, large rocks, formwork and loose material. Proof-roll areas to receive fill with rubber tired roller of sufficient weight. Weak areas or areas where excessive pumping is noted shall be removed, and if required by the City, replaced with select fill. Prior to placing fill, scarify surface to a depth of 6 inches. Moisture content of loosened material shall be such that first layer of fill will readily bond to surface. Top 6 inches shall be free from rocks larger than 3 inches diameter. Place in maximum 8-inch lifts and compact per ASTM D 1557 at optimum moisture content (-1% to +3%). This lift and compaction requirement does not apply to planting areas. Moisten fill to allow drying to correct moisture content before compaction. Do not place fill on subgrade that is over-saturated. Paving subgrade per plan and soils report. Allowing for total thickness of finish paving and base material, fill under paving to bring subgrade to proper elevation. Soft areas that develop under construction operations shall be scarified, aerated or moistened. Compact to full depth required to obtain specified density for each layer.

BEDDING AND JOINT SAND A.

Provide bedding and joint sand as follows: 1.

Washed, clean, non-plastic, free from deleterious or foreign matter, symmetrically shaped, natural or manufactured from crushed rock.

2.

Do not use limestone screenings, stone dust, or sand for the bedding sand material that do not conform to the grading requirements of ASTM C 33.

3.

Do not use mason sand or sand conforming to ASTM C 144 for the bedding sand. Note: Bedding sand durability is important for crosswalks and other vehicular pavements exposed to high traffic. The engineer/architect is advised to evaluate the hardness of bedding sand with the following test method when the pavers and sand will be placed over concrete, or asphalt, and subject to major thoroughfare traffic (over 1.5 million ESALs): One (1) 1.4 kg (3 lbs.) sample of bedding sand can be randomly sampled from the sand source. The sample is dried for 24 hours at 115° to 121° C. (240° to 250° F.). Obtain three (3) subsamples each weighing 0.2 kg (0.5 lbs.) by passing the main sample several times through a riffle box. Carry out a sieve analysis test on each sub-sample according to ASTM C 136. Re-mix each sub-sample and place in a nominal quart/liter capacity porcelain jar with two (2) 25 mm (1 inch) diameter steel ball bearings weighing 75 ±5 grams each. Rotate each jar at 50 rpm for six (6) hours. Repeat the sieve analysis. Record the individual and average sieve analysis. For each sample tested, the maximum increase in the percentages passing each sieve and the maximum individual percent passing should be as follows: Sieve Size No. 200 ( 0.075 mm) No. 100 (0.150 mm) No. 50 (0.300 mm)

Max. Increase 2% 5% 5%

Maximum Passing 2% 15% 35%

4.

Where concrete pavers are subject to vehicular traffic, utilize sands that are as hard as practically available.

5.

Regional Content: Aggregates and sand shall be extracted and processed within 500 miles of the jobsite.

6.

Sieve according to ASTM C 136. Bedding Sand Material Requirements: Conform to the grading requirements of ASTM C 33 with modifications as shown in Table 1.

Verify that subgrade preparation, compacted density and elevations conform to specified requirements. b. Verify that geotextiles, if applicable, have been placed according to drawings and specifications. c. Verify that base materials, thickness, compacted density, surface tolerances and elevations conform to specified requirements. d. Provide written density test results for soil subgrade, base materials to the Owner, General Contractor and paver installation subcontractor. e. Verify location, type, and elevations of edge restraints, concrete collars around utility structures, and drainage holes and inlets. 2.

3.03

3.04

Do not proceed with installation of bedding sand and interlocking concrete pavers until subgrade soil and base conditions are corrected by the General Contractor or designated subcontractor.

PREPARATION A.

Verify base is clean and dry, certified by General Contractor as meeting material, installation and grade specifications.

B.

Verify that base is ready to support sand, pavers and imposed loads.

INSTALLATION A.

Spread bedding sand evenly over the base course and screed to a nominal 1 in. (25 mm) thickness. Spread bedding sand evenly over the base course and screed rails, using the rails and/or edge restraints to produce a nominal 1 in. (25 mm) thickness, allowing for specified variation in the base surface. 1. 2. 3.

B.

Do not disturb screeded sand. Screeded area shall not substantially exceed that which is covered by pavers in one day. Do not use bedding sand to fill depressions in the base surface.

When initially placed on the bedding sand, manually installed pavers often touch each other, or their spacer bars if present. Joint widths and lines (bond lines) are straightened and aligned to specifications with rubber hammers and pry bars as paving proceeds. Lay pavers in pattern(s) shown on drawings. Place units hand tight without using hammers. Make horizontal adjustments to placement of laid pavers with rubber hammers as required. Contact manufacturer of interlocking concrete paver units for recommended joint widths.

Unit Pavers

02780 - 6

3.05

C.

Provide joints between pavers between [1/16 in. and 3/16 in. (2 and 5 mm)] wide. No more than 5% of the joints shall exceed [1/4 in. (6 mm)] wide to achieve straight bond lines.

D.

Joint (bond) lines shall not deviate more than ± 1/2 in. (±15 mm) over 50 ft. (15 m) from string lines.

E.

Fill gaps at the edges of the paved area with cut pavers or edge units.

F.

Cut pavers to be placed along the edge with a masonry saw. Specify requirements for edge treatment in paragraph below.

G.

Adjust bond pattern at pavement edges such that cutting of edge pavers is minimized. All cut pavers exposed to vehicular tires shall be no smaller than one-third of a whole paver. Cut pavers at edges as indicated on the drawings.

H.

Keep skid steer and forklift equipment off newly laid pavers that have not received initial compaction and joint sand.

I.

Use a low-amplitude plate compactor capable of at least minimum of 4,000 lbf (18 kN) at a frequency of 75 to 100 Hz to vibrate the pavers into the sand. Remove any cracked or damaged pavers and replace with new units.

J.

Simultaneously spread, sweep and compact dry joint sand into joints continuously until full. This will require at least 4 to 6 passes with a plate compactor. Do not compact within 6 ft (2 m) of unrestrained edges of paving units.

K.

All work within 6 ft. (2 m) of the laying face must shall be left fully compacted with sandfilled joints at the end of each day or compacted upon acceptance of the work. Cover the laying face or any incomplete areas with plastic sheets overnight if not closed with cut and compacted pavers with joint sand to prevent exposed bedding sand from becoming saturated from rainfall.

L.

Remove excess sand from surface when installation is complete. Excess joint sand can remain on surface of pavers to aid in protecting their surface especially when additional construction occurs after their installation. If this is the case, delete the article above and use the article below. Designate person responsible for directing timing of removal of excess joint sand.

M.

Allow excess joint sand to remain on surface to protect pavers from damage from other trades. Remove excess sand when directed by Architect.

N.

Surface shall be broom clean after removal of excess joint sand.

FIELD QUALITY CONTROL Surface tolerances on flat slopes should be measured with a rigid straightedge. Tolerances on complex contoured slopes should be measured with a flexible straightedge capable of conforming to the complex curves on the pavement surface.

B.

Check final surface elevations for conformance to drawings. Note: For installations on a compacted aggregate base and soil subgrade, the top surface of the pavers may be 1/8 to 1/4 in. (3 to 6 mm) above the final elevations after compaction. This helps compensate for possible minor settling normal to pavements.

C.

The surface elevation of pavers shall be 1/8 in. to 1/4 in. (3 to 6 mm) above adjacent drainage inlets, concrete collars or channels.

D.
