E. PERFORMANCE REQUIREMENTS

E1. GENERAL DRILLING

Page A-4

The Contractor shall perform the drilling at the locations set forth in the Scope of Work. WFLHD will stake or flag each drill site.

NOTE: The actual depth of holes may vary from the amount set forth in the SOW. The Contractor shall be paid for the actual number of holes drilled and the actual depths drilled.

E2. DRILL WORK

a. SOIL SAMPLING

The Contractor shall conduct standard penetration sampling in accordance with standard methods specified by the American Society for Testing and Materials (ASTM) in ASTM D 1586-84, Standard Test Method for Penetration Test and Split-Barrel Sampling of Soils. Shelby tube sampling shall be in accordance with ASTM D 1587-83, Standard Practice for Thin-Walled Tube Sampling of Soils. Standard penetration tests (SPT) shall be conducted in soil continuously to refusal, as determined by the SOW. The Contractor shall open the SPT sampler after each test, and provide the open sampler with sample contained within to the Field Inspector.

Borings shall be advanced using hollow stem augers with a center plug or bit. Subsurface materials at the drill site may preclude SPT sampling in some parts of one or more holes. If material is encountered that is too large for hollow stem augers to advance, the H-size core barrel shall be inserted, and advancement of the hole shall be continued with SPT tests taken as directed by the SOW.

If SPT refusal occurs prior to obtaining the specified depth, the borehole shall be advanced another 1½ feet and the Standard Penetration Test repeated. If SPT refusal occurs again the Field Inspector may direct the Driller to change to core drilling or to continue auguring to the required depths. SPT refusal is defined by AASHTO T 206 and ASTM D 1586, as when the number of blows exceeds 50 for any 6” increment, when the total number of blows equals 100 or if the sampler has not advanced as a result of the last 10 consecutive blows.

If volatile or poisonous gas is encountered, the boring shall be terminated and the COR shall be notified.

b. CORE DRILLING AND SAMPLING If auger and/or SPT refusal, as determined by the Field Inspector occurs, the Contractor will begin core drilling. Coring shall be performed in all fresh, broken, and/or weathered rock, providing continuous core samples of the materials being investigated. Asphalt cores shall be drilled through the entire thickness of asphalt present in the roadway, up to a maximum of 12 inches. Core samples shall be recovered in as intact a state as possible at the locations and to the depths prescribed in the Scope of Work. Core samples shall be emptied from the core barrel into a core tray or other suitable container that minimizes disturbance to the sample for examination.

The core will be boxed by the Contractor after the Field Inspector's examination. All recovered core and other drilled materials shall be delivered to the designated office according to the schedule established in the Scope of Work.

c. SUBGRADE SAMPLING

The COR will determine the frequency of subgrade sampling (e.g. .25 or.50 mile intervals) and/or select specific sampling locations in the SOW. Sampling shall begin by carefully augering through the pavement, if present, without disturbing the underlying baserock, and hand excavating the pavement material to the top of the baserock. Loosen baserock with auger without mixing with underlying materials. Hand excavate and place all baserock into sample bag(s). Hand clean base of hole so as not to mix baserock with underlying material. Carefully

Page A-5 loosen underlying material with auger so as not to mix individual, distinct layers. Sample each distinct strata encountered as determined by the COR to auger refusal or to a minimum depth of 5 feet. Obtain 100 pound samples in sand, silt and clay. Obtain 150 pound samples in predominantly gravel or cobble materials. Sample weight shall not exceed 70 pounds per bag.

The Contractor shall permit the COR to log the completed hole prior to backfilling. Backfill the hole with material suitable for compaction. Compact each 1 foot of loosely placed fill with a tamper. Replace baserock with gravel and/or sand. Replace pavement to original depth with compacted asphaltic patch.

E3. INSTALLATIONS

a. Standpipe Piezometer

The Contractor shall install a PVC standpipe Piezometer to the bottom of the designated borings after drilling is completed. One centering device shall be attached for each 20-25 feet of PVC pipe to insure adequate annular spacing throughout the length of the standpipe piezometer. A slotted PVC screen shall be installed within the water-bearing strata as specified in the SOW. Backfill around the screen shall consist of number 8, uniform graded silica sand. A bentonite seal shall be installed above the screen to the top of the hole. A cap of common materials shall be placed over the seal. A plastic cap shall be installed on top of the PVC pipe. A permanent, locking cover shall be cemented in place surrounding and protecting the top of the PVC pipe. All pipe, screens, bentonite, sand, and other materials necessary for installation shall be furnished by the Contractor.

b. INCLINOMETERS The Contractor shall install flush coupled, ABS plastic inclinometer casing. For installations of less than 100 feet, quick connect inclinometer casing may be used.

For installations of 100 feet or greater, quick connect couplings may not be used.

On 100 foot and deeper installations all casing joints will be connected using a PVC cement as specified by the manufacturer, and two "pop" rivets per joint.

Each joint will be covered by "duct" tape to preclude entrance of grout. The inclinometer casing shall be inserted inside the drill casing. The inclinometer casing shall contain four internal grooves at 90 degree intervals which shall be oriented in the bore-hole at the direction of the COR. The hole will be filled with grout before any drill rods are extracted. Grout shall be pumped continuously until the annular space is completely filled and excess grout is flowing from the hole at the ground surface. Grout for installing inclinometer casing will differ from the grout mixture required when grouting a vibrating wire piezometer in the same hole as inclinometer casing. Grout shall consist of a prepackaged Portland cement that meets the requirements of ASTM C 150-94, mixed with powdered bentonite. One cup of soda ash will be added to each grout batch of 100 gallons or less. The soda ash should be added before the cement is added.

Drillers are accustomed to mixing water and bentonite first, but this will not allow you to control the water-cement ratio. Mix water and cement first. Then add bentonite.

There is no particular amount of bentonite that you must add. The thickness of the grout varies with water, temperature, and agitation, so the amount of bentonite required will vary.

The quantity of the bentonite ingredient to be added must be adjusted to obtain a suitable consistency. A watery mix is NOT acceptable. A mix that is too thick cannot be pumped. The Marsh funnel number of the liquid grout should be about 55 seconds +/- a few seconds

Page A-7

When you mix cement and water first, the amount of bentonite has to be adjusted. The amount is rarely ever equal to exactly 25 lbs. The final quantity also varies with the type of bentonite used, the method of mixing and the pH of the water.

Adjust the amount of bentonite to produce a grout with the consistency of heavy cream. If the grout is too thin, the solids and the water will separate. If the grout is too thick, it will be difficult to pump.

A permanent, locking 10 inch diameter cover shall be cemented in place surrounding and protecting the top of the PVC casing.

c. SONDEX: Installing Sondex pipe with inclinometer casing.

The contractor will need a 3 inch Sondex pipe (corrugated plastic pipe used for drains), Sondex pipe couplings, Sondex sensing rings, strong cable ties (16 inches or longer) or wire, mastic tape, and vinyl tape. The Sondex couplings are used to join lengths of Sondex pipe.

The cable ties or wire are used to secure the Sondex pipe to the bottom of the casing and to hold the Sondex couplings onto the Sondex pipe. The mastic tape and vinyl tape are used to

Mix soda ash with water first then add the cement. Then mix in the bentonite.

Adjust the amount of bentonite to produce a grout with the consistency of heavy cream. If the grout is too thin, the solids and the water will separate. If the grout is too thick, it will be difficult to pump.

Page A-8 seal the bottom and each coupling so that grout cannot enter in the void between the Sondex pipe and the inclinometer casing.

Cut an 8 foot section of Sondex pipe. This will be attached to the bottom section of inclinometer casing. Cut the remaining Sondex pipe into 10 foot sections.

Attach sensing rings to the Sondex pipe at 3 foot intervals or as directed in the

Statement of Work. Protect the rings from corrosion with mastic and tape.

Prepare the bottom section of casing as usual, and then secure the bottom 12 to 18 inches of the 8 foot section of Sondex pipe to the bottom of the casing. This can be difficult because (1) the Sondex pipe is quite strong and larger in diameter than the casing, and (2) the bottom of the Sondex pipe must be sealed against entry of grout.

Seal the bottom of the Sondex pipe using mastic and tape. Slit the bottom of the Sondex pipe to flatten it against the inclinometer casing, secure it to the casing with cable ties or wire, and then carefully waterproof it.

Lower the first section into the borehole so you can connect the next section. If the borehole has water in it, the buoyancy of the inclinometer casing must be overcome by adding water inside the inclinometer casing or by other means. The inclinometer casing will not be held in place from the top.

Slide a 10 foot length of Sondex pipe over a 10 foot length of casing. Join the casing, then joint the Sondex pipe. Fit the Sondex coupling onto the butted ends of Sondex pipe. Secure with cable ties and then waterproof the entire coupling.

Lower the pipe into the borehole so you can connect the next section. Join the casing, and then join the Sondex pipe. Continue until the casing has reached the specified depth.

Protect the top of the casing and Sondex pipe from grout spills.

Backfill the borehole with grout. Use the grout mix specified in the scope of work.

F. FIELD INSPECTION- Inspector duties include but are not limited to;

The borings should be drilled as close to the marked locations as possible. Some may need to be offset a foot or two to fit the drill in next to the guardrail but make sure the driller doesn’t move the boring just so they have a 4 foot wide walking path along the drill.

Take an accurate measurement of the pavement thickness to the nearest 0.1 inch and try to determine the base thickness as best you can.

Take photos of each core box on site. Place core in the box like you’re reading a book, starting at the top and working from left to right and down. Label the beginning and end of each core run. Using a permanent marker, draw a line across all mechanical fractures.

Label all samples with at least the project name, boring number, depth, date, and sample number.

Record the recovery of each split spoon sample to the nearest inch. Take a photo of each boring location.

Page A-9

The boring Stationing is listed on the table in the drill request. Measure the offset from the existing centerline of the actual drilled location and note it on the logs.

Take water level reading during drilling, after completion, and after withdrawal of the drill rods.

When coring and the material is highly weathered, take SPT samples to get some idea how strong the rock is.

Field Inspector’s Report The field inspector will submit a daily report with the quantities delivered that day to match the quote sheet items. The field inspector will sign, and the driller will both sign the completed form.

Field Inspectors report format provided by the Government.

DATALOGGERS

The Field Inspector may be required to set up single channel dataloggers for use with vibrating wire piezometers. The vibrating wire piezometers will be wired to the dataloggers at the drill site. The dataloggers currently in use by WFLHD are produced by Slope Indicator. The Inspector will use the associated software to input calibration factors and set the reading schedule. The software is a free download from Slope Indicator’s website.

The Field Inspector may be required to wire and program Campbell Scientific CR10X dataloggers for use with thermisters strings, vibrating wire piezometers, in-place-inclinometers and various other geotechnical instruments. The Inspector must be familiar with the use Campbell Scientific CR10X dataloggers and use industry standard practices and procedures as well as following Campbell Scientific guidelines given in the owner’s manual. WFLHD will provide the CR10X dataloggers and owner’s manuals when Campbell Scientific equipment is called for in the Scope of Work.

G. WATER LEVEL TESTING

DOCUMENTATION

The Contractor shall monitor the drill runs and depths, SPT Blow counts, water color changes and estimated percent (%) water return. On a per drill run basis, the Drill Operator shall inform the Field Inspector of the materials encountered (fresh rock, broken rock, weathered rock, soil, boulders), type of drilling used, drilling activity performed, and measured depth to water.

The Contractor shall document any information that might give an indication to the character of, or a change in, the subsurface materials being encountered. The Contractor shall confirm with the Field Inspector the depth of all sample locations, beginnings and endings of runs, and water depths to the nearest tenth of a foot.

Page A-10

The Driller shall furnish a signed copy of the Driller’s Daily Log to the Field Inspector at the close of each workday. The Field Inspector will immediately review the Driller’s Daily Log for consistency with the Government’s daily records. The Field Inspector will note all difference and discuss with the Driller. If both parties agree, changes shall be made to the Driller’s Daily Log. All unresolved differences shall be recorded by the Field Inspector, signed by the Field Inspector and the Driller, and the Field Inspector will notify the COR by phone within 24 hours of close of the subject workday.

The Contractor shall mail the original Driller’s Daily Log to the COR to the address in the SOW within 72 hours of the subject workday. These daily records and the samples are considered deliverables and shall be received prior to payment authorization.

Upon completion of the drilling, all drill holes, except those where observation wells are installed, or if the hole is in the traveled-way of the pavement, shall be clearly marked.

The Contractor shall furnish and install a 4 foot wood lath. The contractor shall label the lath with a permanent marking pen or paint pen (or durable equivalent). Each lath shall have the following information:

1. Drill hole number and station

2. Final hole depth

3. Date drilling completed

I. ABANDONMENT OF HOLES AND LOST EQUIPMENT

Should the drilling casing, augers, or apparatus be removed from a bore hole, or should the hole be abandoned, without the permission of the COR, or should a hole be started and for any reason not carried to the depth required by the SOW, or should the Contractor fail to furnish the COR, the required samples, cores, and daily logs, the Contractor shall make an additional boring at a location near the original site which will be selected by the COR. No payment shall be made for either the abandoned hole or any cores obtained therein. However, the contractor shall make a record of abandoned bore holes and note thereon the reasons for the abandonment. All completed test holes shall be abandoned in accordance with established state procedures.

Equipment lost in the drill hole or at any drill site will be the responsibility of the Contractor.

J. ROCK CORE PRESERVATION

The rock cores shall be placed in waxed cardboard or corrugated plastic core boxes provided by the Contractor. The cores from each boring shall be kept separate and the cores shall be properly placed in the order in which they were removed from the core barrel.
