3.03 SUPPORT SYSTEM WITH TIEBACKS

A. Install tieback system in accordance with approved working drawings.

B. Stress tiebacks to proof loads equal to 140 percent of maximum design load and maintain proof load for 30 minutes prior to reducing to design load. Reject tiebacks which lose more than five percent of proof load during 30-minutes period.

C. Apply proof loads in increments of five tons at one minute intervals and provide means to measure

load application within accuracy of plus or minus five percent.

D. After reducing tieback load to design load, encase anchors in grout maintaining design load until anchors are fixed in place.

E. In transfer of loads from jacks to support system, use fixation method which will limit load loss to no

more than five percent of design load.

F. Provide and maintain convenient access and appropriate means to accomplish these observations. G. Preliminary and Creep Tests on Tiebacks:

1. Reapply proof loads equal to 140 percent of design load at each level of support in

excavation on first installation on each side of excavation at horizontal intervals not exceeding 500 feet and wherever there is significant difference in soil in which tiebacks are installed.

2. As specified for proof loading, apply proof loads in increments of five tons at one minute intervals. Provide means of measuring load applications with an accuracy of plus or minus five percent of design load. Maintain proof load for 24 hours prior to reducing it to design load.

3. Make records of axial movement with incremental applications of load as well as amount and time of load fall-off with no pumping of jack or axial movement during 24-hour period that proof load on tieback is maintained. If during 24-hour period axial deformation of tieback system exceeds 0.02 inch or decrease in jack pressure without pumping is more than five percent after correcting for temperature changes during the test period, redesign tieback system to satisfy requirements.

H. Vertical Support System with Tiebacks:

1. Install piles or other vertical support system members incorporated in a system utilizing

tiebacks so that they are capable of resisting vertical components of tieback loads without significant settlement during excavation and construction.

2. Install vertical support members so that settlements will not be caused by construction. In general, install members to be end-bearing in stratum below maximum depth of excavation and capable of carrying total vertical loads without assistance of skin friction at depth of excavation.



3.04 LAGGING

A. Unless otherwise shown or specified, provide timber lagging of three inches minimum thickness where it spans soldier piles placed at distances five to seven feet on centers and for excavation depths up to 25 feet. Increase minimum lagging thickness to four inches for excavation blow 25 feet in depth.

B. Install lagging members in a manner which will prevent loss of soil. Wedge lagging members

against either undisturbed earth or compacted fill. 3.05 TRENCH EXCAVATION

A. Perform sheeting, shoring and bracing for trench excavation for utility facilities and other purposes in accordance with specified safety requirements.


A. Tests: 1. Where system of tiebacks is proposed in conjunction with or in lieu of struts, bracing and

shores, undertake approved number of on-site tests to demonstrate adequacy of tiebacks for typical subsurface conditions.

2. Conduct tests and obtain approval prior to use of tieback system for excavation support.

B. Remove components of support system which inadvertently penetrate or encroach on permanent structure without endangering stability of support.

3.07 REMOVAL OF SUPPORTING SYSTEM

A. Remove sheeting, bracing and shores as trenches and other excavations are being backfilled, except where and to such an extent as the Project Manager shall require, in writing, that the same be left in place or where he shall permit the Contractor to leave the same in place at the Contractor's request and cost.

B. Cut off sheeting left in place whenever and at such points as the Project Manager shall require and

remove from the site the portion cut off. No additional compensation will be allowed for such cutting, removal and disposal.

A. Silt Barrier Fence: Install fence near limits of excavation or fills where indicated on Drawings or as directed by Engineer to control erosion until disturbed areas are permanently stabilized.

1. Construct silt barrier fencing with Class 3 geotextile material with wire or plastic mesh support fencing fastened to support posts. Overall height of fabric above ground to be nominally 18 inches. Provide geotextile material of width required including an 8-inch to 12-inch section for embedment.

2. Excavate a trench 6 inches wide by 6 inches deep on fabric side of barrier and along inside of post line.

3. Install posts a minimum of 18 inches deep, by an approved method, on downstream edge of trench at a maximum spacing of 10 feet.

4. Provide wire or plastic mesh support fence when used, of sufficient height to extend from top of fabric to ground or into excavated trench and be securely fastened to posts. Provide staples for wood posts and tie wires for steel and plastic posts, with a minimum of three fasteners per post.

5. Secure geotextile fabric material by fasteners to top of wire mesh and posts, keeping sag to a minimum, and at a maximum spacing of 30 inches. Extend fabric 8 to 12 inches into excavated trench for embedment. Backfill and compact over geotextile material to prevent water from flowing under fabric. Overlap fabric roll ends a minimum of 6 inches at post locations.

6. Preassembled silt barrier fence systems to be approved by Engineer. Install preassembled fence systems in accordance with manufacturer's recommendations.

7. Construct silt barrier fence across a ditch or swale area of sufficient length to eliminate end flow, with ends pointing upstream and upslope.

8. Maintain silt barrier fence satisfactorily to keep functional. This includes removal of trapped sediment and cleaning fabric of trapped sediment by tapping fabric material when dry. Replace fabric not functioning due to clogging, damage, or deterioration as directed by Engineer.



9. Remove fencing when no longer required, as determined by Engineer. Dispose of fencing materials in a suitable manner and restore area where fence had been erected at no additional cost to SEPTA.

B. Pumped Water Sediment Control Device (PWSCD):

1. Install the PWSCD on a slope. It should be placed so the incoming water flows into the bag

and will flow through the PWSCD and then flow off the site without creating more erosion. The neck of the PWSCD should be tied off tightly to stop the water from flowing out of the PWSCD without going through the walls of the bag. To increase the surface area being used, the PWSCD may be placed on a gravel bed to allow water to flow in all directions.

2. The PWSCD is considered full and should be disposed when it is impractical for the bag to filter the sediment out at a reasonable flow rate and should be replaced with a new PWSCD.

3. Disposal may be accomplished as directed by the Engineer. If the site allows, the PWSCD may be buried on site and seeded, visible fabric removed and seeded or removed from site to a proper disposal area.

C. Inlet Sediment Control Device (ISCD):

1. Installation and emptying instructions in accordance with manufacturers printed

instructions.

D. Temporary Seeding and/or Mulching:

1. General: Engineer reserves right to direct temporary seeding and/or mulching of disturbed areas in event permanent grading and seeding cannot be immediately performed. Include cost of temporary erosion control measures in appropriate pay item.

2. Liming: Lime application rates will be determined on basis of tests performed by Contractor or apply a minimum of 800 pounds of agricultural lime stone per 1000 square yards.

3. Fertilizer: Apply fertilizer at a rate of 140 pounds per 1000 square yards of 10-20-20 fertilizer or in conformance with results of soil tests performed.

4. Tilling: Till seedbed to a depth of 3 inches prior to seeding. Lime (if required) and fertilizer may be applied during tilling operation.

5. Seeding: Type of temporary seed mixture to be used is determined by Engineer. Sow seed at rate indicated in Temporary Seeding Mixtures Article. Cover seed with ½ inch of topsoil and lightly roll seeded area.

6. Mulching: Apply hay or straw mulch at rate of three tons per acre on slopes of 1.5 to 1 or flatter. Apply asphalt material to anchor mulch at rate of 50 gallons per ton on straw or hay mulch. Apply wood cellulose fiber mulch on slopes steeper than 1.5 to 1 at a rate of 1500 pounds per acre. Wood chips, recovered from clearing and grubbing operations, is acceptable as mulch for temporary seeding. Use at a rate of 35 cubic feet per acre in lieu of straw or hay.

E. Mulching Alone: For embankments or cuts 1.5 to 1 or flatter, susceptible to critical erosion during

periods of cold weather or other site conditions, Engineer may require a three ton per acre application of straw or hay mulch for temporary erosion control and later seeding. Apply asphalt for anchoring mulch at a rate of 50 gallons per ton. Straw or hay may be rolled immediately with a



sheepsfoot roller to anchor mulch in lieu of using asphalt. When weather becomes favorable, seed areas provided with a mulch cover alone using normal application rates of seed, fertilizer, and lime. If additional mulch is needed, rate of application and area to be mulched will be as determined by Engineer.

F. Matting for Erosion Control: Provide matting in lieu of mulch on slopes 3:1 and steeper or when directed by Engineer.

1. Prepare area to be covered as a fine seedbed, fertilized, and seeded. Place matting

immediately and water to give a firm bond to soil and start germination of seed. Either jute or excelsior matting may be used.

2. Jute Matting: Lay jute matting snugly to ground with a 4-inch overlap on edges and a 12-inch overlap on ends. Make check slots from a 2-foot-wide strip of jute matting folded and buried in a 6-inch-deep trench with a 6-inch flap extending on each side of trench. Place check slots perpendicular to water flow, tamped and stapled in place before jute matting is laid. Use check slots for jute matting when slope exceeds a 5 percent grade. On grades or slopes steeper than 5 percent, Engineer will determine spacing of check slots.

3. Excelsior Matting: Lay excelsior matting with netting on top and fibers in contact with soil over entire area. Butt ends and sides of excelsior blanket snugly and staple. It is not necessary to dig check slots, anchor ditches, or bury ends of excelsior matting.

4. Staples: Hold matting in place by means of wire staples driven at a 90-degree angle to soil surface. Space staples not more than 3 feet apart in three rows for each strip, with one row along each edge and one row alternately spaced in middle. Space staples 6 inches apart across matting ends and check slots width.

3.02 MAINTENANCE

A. Begin maintenance operations immediately and continue throughout construction period until

Contract is completed. Inspect sediment control structures and repair after each storm. 3.03 SOIL EROSION AND SEDIMENTATION PLAN

maintain workability of the concrete. 4. Use only clean tools.

B. Conveying:

1. Perform concrete placing at such a rate that concrete which is being integrated with fresh concrete is still plastic.

2. Deposit concrete as nearly as practicable in its final location so as to avoid separation due to re-handling and flowing.

3. Do not use concrete which becomes non-plastic and unworkable, or does not meet required quality control limits, or has been contaminated by foreign materials.

4. Remove rejected concrete from the job site.

C. Placing Concrete in Forms: 1. Deposit concrete in horizontal layers not deeper than 18", and avoid inclined construction

joints. 2. Remove temporary spreaders in forms when concrete has reached the elevation of the

spreaders. 3. Deposit concrete as near as possible to final position. Do not drop concrete more than

three feet.

D. Cold Weather Concreting: 1. Temperature of concrete delivered at the job-site shall conform to the following

temperature limitations:



Minimum Concrete Temperature, (Degrees F.)

Air Temperature Degrees F.

For Sections with Least Dimension <

12 in.

For Sections with Least

Dimension 12 in or Greater

30 to 45 60 50 0 to 30 65 55

2. If water or aggregate is heated above 100 degrees F, combine water with aggregate in the

mixer before cement is added. Do not mix with water or with mixtures of water and aggregate having a temperature greater than 100 degrees F.

3. Provide equipment for heating concrete materials and protecting concrete during freezing or near-freezing weather. Do not use foreign materials or materials containing snow or ice.

4. Surfaces which the concrete is to come in contact with must be free of frost, snow and ice. 5. Concrete placed in forms shall have a temperature of 50 degrees F. or higher after

placement. Maintain this temperature a minimum of 5 days. Provide additional time if necessary for proper curing.

6. Housing, covering or other protection used in curing shall remain intact at least 24 hours after artificial heating is discontinued. Do not place dependence on salt or other chemicals for the prevention of freezing.

7. Perform cold weather concreting work in accordance with ACI 306R.

E. Hot Weather Concreting: 1. Temperature of concrete delivered at the job-site shall not exceed 90 degrees F. 2. Cool ingredients before mixing to prevent temperature in excess of 90 degrees F. 3. Make provisions for windbreaks, shading, fog spraying, sprinkling, or wet cover when

necessary. 4. Perform hot weather concreting work in accordance with ACI 305R.

3.4 CONSOLIDATION

A. General: 1. Consolidate each layer of concrete immediately after placing, by use of internal concrete

vibrators supplemented by hand spading, roofing, or tamping. 2. Do not vibrate forms or reinforcement. 3. Do not use vibrators to transport concrete inside the forms. 4. Use vibration equipment of internal type and not the type attached to forms and

reinforcement. 3.5 DEFECTIVE CONCRETE WORK

A. Porous areas, open or porous construction joints and honeycombed concrete will be considered to indicate that the requirements for mixing, placing and handling have not been complied with and will be sufficient cause for rejection of the Work.

B. Defective work exposed upon removal of forms shall be entirely removed or repaired within forty-

eight hours after forms have been removed.



3.6 REPAIR OF DEFECTIVE CONCRETE

A. General: The Project Manager will determine the extent and manner of action to be taken for the correction of defective concrete as may be revealed by surface defects or otherwise.

3.7 CONCRETE FINISHING

A. Finishes: Finish exposed concrete surfaces true and even, free from open or rough area, depressions or projections. Bring concrete up in vertical pours to the required elevation, strike-off with a straight edge and float-finish.

1. Floated Finish: After concrete has been place, consolidated, struck off and leveled, do not work further until ready for floating. Begin floating when water sheen has disappeared and when the surface has stiffened sufficiently to permit the operation. During or after first floating, check plainness of surface with a 10-ft straightedge applied at not less than two different angles. Cut down high spots and fill low spots during this procedure to produce a surface with true planes within 3/16 inch in 10 ft. as determined by a 10-ft. straightedge placed anywhere on the slab in any direction. Following straightedge checking, re-float slab immediately to uniform sandy texture.

2. Flat Trowel Finish: Obtained by hand or power trowelling a "Floated Finish" with a single trowelling. This trowelling (first after power floating) shall produce a smooth surface which is relatively free of defects but which may still show some trowel marks.

3. Broom or Belt Finish: Immediately after concrete has received a "Floated Finish", give surface a coarse transverse scored texture by drawing a broom or burlap belt across the surface.

B. Application for Finishes:

1. Floated Finish: a) Surfaces to receive "Flat Trowel Finish". b) Surfaces to receive "Broom or Belt Finish".

2. Flat Trowel Finish: Curbs. 3. Broom or Belt Finish: Sidewalks.
