5. PROJECT DETAILS

5.1. Scope of Work

This work includes the furnishing of all material, labor, equipment, water supply and all else necessary for completing certain soil borings and pavement cores as described herein. It also includes the sampling of the subsurface soil characteristics as described herein.

5.2. Supervision

The work shall be performed in the presence of a representative from the Town of Manchester

Engineering Division, herein referred to as the Engineer. The Engineer will check the logs of the explorations to determine that the information designated herein is being obtained. The Engineer shall be notified at least 48 hours in advance of deviations from the schedule of operations.

5.3. Existing Conditions

Before any subsurface exploration is done, the Contractor shall call “Call Before You Dig” to have existing underground utilities marked out in the vicinity of the proposed borings. The location of the boring or other subsurface exploration may be varied from that shown on the plans if necessary, in order to prevent damage to existing utilities. During the progress of the work, the Contractor shall cooperate with the owners of the utilities and permit their representatives access to the work to determine if their utilities are being endangered in any way. Any relocation of borings or other subsurface explorations shall be done only with the approval of the Engineer.

5.4. Soil Borings

Soil Borings shall be performed as necessary to take split spoon samples and stationary piston samples in soil and rock cores in underlying bedrock or boulders as directed by the Engineer.

Unless otherwise directed by the Engineer, it is anticipated that borings shall be made to depths of 20’ below existing ground surface.

For determination of soil strata, borings will normally be 3” minimum diameter holes in which 2” O.D.

split spoon samples will be taken. If coarse material is encountered, borings may be 4” minimum diameter holes in which 3” O.D. split spoon samples will be taken. The 3” sampler shall be used regardless of the size of casing being employed if, in the opinion of the Engineer, such sampler will recover a representative sample. Undisturbed samples may also be taken. For recovering such samples, a 3” stationary piston sampler will be required.

For determination of depth to, and soundness of, bedrock, borings will be 3” minimum diameter holes through which rock cores no less than 1 7/8” in diameter (NQ) can be recovered.

In boring methods using a heavy drilling fluid, casing shall be driven to such depth below ground surface as required to maintain the top of the hole. Thereafter, heavy drilling fluid may be used to maintain the boring. At the completion of such holes, the heavy drilling fluid shall be removed by flushing or bailing in order that the true water level may be accurately determined.

In borings using hollow-stem auger methods, holes shall be advanced using hollow-stem auger flights capable of accommodating 2” diameter samplers at locations where 3” borings are specified and 3” O.D.

samplers where 4” borings are specified. The inner rod-center plug assembly shall be used to prevent disturbed soil from entering the stem.

Hollow stem auger borings which fail to penetrate to the specified depth shall be continued by other methods which may include use of the cased methods described herein.

No soil samples shall be obtained by driving and removing casing.

Casing

Casing shall be driven vertically through the earth or other materials to such depth below the surface of the ground as required to maintain the sides of bore holes or as directed by the Engineer. The blows per foot required for the penetration of the casing shall be recorded and included in the Contractor’s drill record. Simultaneous washing and driving of the casing will not be permitted except by order of the

Engineer, and where so permitted the elevations between which water was used in driving the casing must be recorded.

It shall be the Contractor’s responsibility when boulders or other obstacles are encountered to carry the drilling through or past such obstacles.

Casing shall be at least 3” nominal diameter pipe for borings in which 2” O.D. samplers are used and 4” nominal diameter pipe where 3” O.D. samplers are used. The casing shall also be 3” minimum nominal diameter for borings in which rock cores are taken.

The weight of hammer for driving the casing shall be 300 pounds and the drop shall be 24”.

Split Spoon Sampling

Split spoon samples shall be obtained at approximately 12” below the ground surface and at the beginning of every change of stratum and at intervals not to exceed 5’ unless otherwise directed by the

Engineer. At these points, advancement of the borings shall be stopped, and all material removed from inside the casing. The use of water for cleaning out between samples will generally be allowed, and approved chopping bits, augers, or sampling spoons may be used for cleaning the casing or bore hole preparatory to taking split spoon samples. The re-use of wash water will generally be permitted. The pump used for wash water shall have sufficient capacity to adequately clean the hole before sampling the material which has been loosened. The samples shall be obtained by driving a split spoon sampler

18” into the undisturbed material below the bottom of the casing or bore hole.

When sampling in granular materials, the casing shall be kept full of water at all times, unless otherwise directed. The casing shall be filled with water and covered at the end of the working day, and the drop recorded when work is resumed.

Split spoon samplers shall be equipped at the top with a reliable check valve and shall have a minimum inside sampling length of 24”. They shall have a minimum inside diameter of 1 3/8” or 2 ½” as directed by the Engineer. A recovery of less than 12” of soil in a split spoon sampler shall not be considered an acceptable sample, and a second sample shall be taken immediately below the unsuccessful recovery, after first advancing the hole into undisturbed material. If difficulty is experienced in the first attempt to recover a sample the split spoon sampler for the second attempt shall be equipped at the bottom with a basket shoe or other spring-type sampler retainer. Flap (trap) valves will be allowed only with the approval of the Engineer. If the earth is very compact and cannot be sampled using the split spoon sampling methods required herein, the Contractor shall resort to coring methods to obtain a sample.

To facilitate determination of the relative resistance of the various strata, the 2” O.D. split spoon samplers shall be driven by a 140 lb. hammer having a 30” drop. 3” split spoon samplers shall be driven by a 300 lb. hammer having a 17” drop. The number of blows for each 6” of penetration shall be recorded.

Undisturbed Sampling

Undisturbed samples shall be taken with a tube containing a close fitting piston operated by a separate piston rod, and a sampler head with appropriate spring and piston rod check. The sampler shall be similar in type to the Stationary Piston Sampler, as manufactured by Acker Drill Co., Inc., Scranton, PA. The tube shall have a #16 wall thickness and a 3” O.D., shall be 30” long, shall be provided with a sharp cutting edge and positive inside clearance and shall be bright, clean and free from rust. The end of the tube shall be drawn in so the I.D. of the cutting edge shall be 1/64” less than the I.D. of the sampler tube.

Samples shall be taken in a “piston clamped flush position” unless otherwise directed by the Engineer, to produce samples 24” long.

Before each sample is taken, the hole shall be thoroughly cleaned with a cleanout jet auger, similar to

Sprague & Henwood, Inc., Cat. No. 15239. If a sample had just been taken, the casing or bore hole shall be driven so that its bottom edge will be 3” below the elevation to which the bottom edge of the sampler had been pushed. The casing or bore hole shall then be cleaned to the bottom edge as specified above and the bottom elevation of the casing or bore hole shall be recorded.

The sampler shall be jacked or forced into the ground without rotation in one continuous operation under steady pressure at a rate of from 6" to 12" per second.

After the sample is pushed into the ground, the sample shall be allowed to rest for a period of 5 minutes to permit building up of side friction between the sample and the inside wall of the tube. The drill rod shall be rotated two or three full turns in order to tighten all joints and to twist off the bottom of the sample from the underlying soil.

The sample shall be withdrawn slowly through the water or mud filled casing to avoid erosion of the bottom of the sample. At the same time, the water or mud level in the casing shall be maintained at the top.

The tube with sample shall be detached from the head of the mechanism in a manner to cause as little disturbance as possible to the sample.

Rock Coring

Wherever rock is encountered, the Contractor shall take continuous core samples to a depth directed by the Engineer by means of a rotary method and diamond bit of such size as will yield cores not less than 1

7/8” in diameter (N-series).

The diamond core bit shall be started in the hole and the bedrock shall be drilled until the required depth is reached. When the core is broken off, it shall be withdrawn, labeled and stored before the drilling is continued. The holes shall be carried into the bedrock to a depth sufficient to permit the

Engineer to determine to his satisfaction the character of the bedrock penetrated. In general, it is expected that the depth of the core holes in bedrock will be 5’ or as directed by the Engineer. The maximum length of each coring run will be 5’.

Cores shall be carefully handled to insure their proper identification and placed in the order in which they are removed from the hole and care shall be taken to recover as large a percentage of core as possible. The contractor shall regulate the speed of the drill and remove the cored as often as necessary to insure the maximum percentage of recovery.

Should the recovered length of core be less than 50% of the length cored for any run, the Contractor shall adopt such measures as may be necessary to improve the percentage of recovery. These measures include, but are not limited to, changes in the type of diamond bit, feed rate, speed of rotation, volume of circulation, use of Series “M” core barrel, length of run per removal and change in machine operator. In those cases where, in the opinion of the Engineer, the competency, structure and condition of the bedrock are critical to the design, the Engineer reserves the right to direct that the Series “M” core barrel be used.

Abandoned Boring Holes

Should the casing or apparatus be removed from a bore hole, or should the hole be abandoned, without permission of the Engineer, or should a boring be started and for any reason not carried to the depth required by the Engineer, or should the Contractor fail to keep complete records of materials encountered or furnish the Engineer the required samples and cores, the Contractor shall make an additional boring at a location selected by the Engineer, and no payment shall be made for either the abandoned hole or any samples or cores obtained therein. However, the Contractor shall make a record of abandoned bore holes and note the reasons for the abandonment.

5.5. Sample Preservation

Split Spoon Samples: Representative specimens of each sample shall be preserved. The containers for preserving split spoon samples shall be large-mouth, round, screw top, air tight, clear glass jars. Size of jars shall be 16 oz. for all drive samples. The specimens shall be placed in the jars and tightly capped with gasket sealed caps as soon as taken in order to preserve the original moisture in the material. Samples which retain form upon removal from the sampling spoon shall not be jammed or forced into the jar. The jars shall be suitably boxed in cardboard boxes, marked and identified with legible labels as directed by the Engineer. These labels shall show the date, town, project name, road name, project number, station and offset, boring number, sample number, depth at which sample taken, the driller’s name, number of blows for each 6” penetration and soil classification of the sample. The samples shall be protected against freezing and the jars against breaking.

Undisturbed Samples: All samples shall be preserved. In preserving samples, a maximum of 1” of material shall be removed from the bottom of the tube and used to make up a jar sample. All disturbed material shall be removed from the top of the tube. A 1” wax seal shall be placed at the top and bottom of remaining undisturbed material and allowed to harden. Empty portions of the tube shall then be filled with firmly pressed damp sand and the tube ends shall be sealed with a metal or plastic cap, friction tape and wax. Wax shall be Socony Vaccum Product 2300 or equal.

Undisturbed samples shall be marked upon removal from the ground to indicate the upper end of the sample and shall be transported and stored in the same relative position as they existed in the ground.

The weight of all stationary piston samples shall be determined and recorded immediately after they are sealed and ready for transfer to the custody of the Engineer. The utmost care shall be used in protecting the stationary piston samples from freezing, jarring or disturbance of any kind.

Rock Cores: The rock cores shall be placed in suitable wooden boxes so partitioned that the cores from each boring will be kept separate and the cores shall be properly placed in the order in which they were removed from the core barrel, and to show where portions, if any, were lost.

Rock cores shall be suitably labeled and arranged neatly in the boxes in the sequence in which material was removed from the hole. Adjacent runs shall be separated by means of wood blocks, on which the elevation of the top and bottom of the run shall be clearly, accurately and permanently marked.

The core boxes shall have a cover hinged at one edge and latched at the other edge and shall be constructed to withstand normal abuse in shipment. The boxes shall be properly labeled showing the date the core was taken, town, project name, road name, project number, station and offset, boring number, depth of core and driller’s names.

Core boxes shall be constructed of dressed lumber, be approximately 5’ in length and have a capacity for

20’ of rock core in each box. Core boxes shall be completely equipped with all necessary partitions, covers, hinges, latches for holding down the cover, and suitable for identification plates and tags.

5.6. Mobilization and Demobilization
