PART 2 - ENGINEER'S REVIEW ACTION

2.01 SHOP DRAWINGS AND SAMPLES:

A. Items within transmittals will be reviewed for overall design intent and will receive one of the following actions:

1. R - Reviewed, No exceptions taken.

2. E - Exceptions taken, Make correction noted

3. RR - Revise & Resubmit

B. Transmittals received will be initially reviewed to ascertain inclusion of Contractor's approval stamp. Drawings not stamped by the Contractor or stamped with a stamp containing language other than that specified above, will not be reviewed for technical content and will be returned without any action.

C. Transmittals returned with Action "R" and "E" are considered ready for fabrication and installation. If for any reason a transmittal that has an "R" and "E" Action is resubmitted, it must be accompanied by a letter defining the changes that have been made and the reason for the resubmittal. Destroy or conspicuously mark "SUPERSEDED" all documents having previously received "R" and "E" Action that are superseded by a resubmittal.

D. Transmittals with Action ""R" and "E" combined with Action "RR" (Revise and Resubmit) will be individually analyzed giving consideration as follows:

E. The portion of the transmittal given "RR" will not be distributed (unless previously agreed to otherwise at the Preconstruction Conference). One copy or the one transparency of the "RR" drawings will be marked up and returned to the Contractor. Correct and resubmit items so marked.

Park 001340 - 5 Shop Drawings, Product Data &

Samples, O&M Manuals

F. Items marked "R" or "E" will be fully distributed.

G. If a portion of the items or system proposed are acceptable, however, the major part of the individual drawings or documents are incomplete or require revision, the entire submittal may be given "RR" Action. This is at the sole discretion of the Engineer. In this case, some drawings may contain relatively few or no comments or the statement, "Resubmit to maintain a complete package." Distribution to the Owner and field will not be made (unless previously agreed to otherwise).

H. Failure to include any specific information specified under the submittal paragraphs of the specifications will result in the transmittal being returned to the Contractor with "RR” Action.

I. In addition to calculations stamped and returned "Engineer's Review Not Required," other transmittals such as submittals which the Engineer considers as "Not Required,” submittal information which is supplemental to but not essential to prior submitted information, or items of information in a transmittal which have been reviewed and received "R'" or "E" Action in a prior transmittal, will be returned with Action "Engineer's Review Not Required."

J. Samples may be retained for comparison purposes. Remove samples when directed. Include in bid all costs of furnishing and removing samples.

K. Approved samples submitted or constructed, constitute criteria for judging completed work.

Finished work or items not equal to samples will be rejected.

5. All carrier pipe installed by jacking shall be supported by a quarter point cradle of Class B or Class PB concrete as specified by the OWNER across the jacking pit and to the first joint in the ditch section on each end.

6. The distance that the excavation shall extend beyond the end of the pipe depends on the character of the material, but it shall generally not exceed 2-ft. (0.6m). The pipe preferably shall be jacked from the low or downstream end. Lateral or vertical variation in the final position of the pipe from the line and grade established by the OWNER shall be permitted only to the extent of 1-in. per 10-ft. (25mm per 3m), provided that such variation shall be regular and only in one direction and that the final grade of the flow line shall be in the direction indicated on the plans.

7. Once jacking of pipe is begun, the operation shall be carried on without interruption, insofar as practicable to prevent the pipe from becoming firmly set in the embankment.

8. Any pipe damaged in jacking operations shall be removed and replaced by the CONTRACTOR at the CONTRACTOR’S entire expense.

9. The pits or trenches excavated to facilitate jacking operations shall be filled as soon as practicable or as directed by the OWNER. The pits or trenches shall then be backfilled in accordance with the location and conditions as are covered elsewhere in these specifications.

10. If a carrier pipe is laid through an encasement pipe, the bedding of crushed rock, concrete, grout or granular material, if any, shall be considered a part of the unit price of the jacking operation.

C. Construction by Boring:

1. The hole shall be bored mechanically with a suitable boring assembly designed to produce a smooth, straight shaft and so operated that the completed shaft shall be at the established line and grade. The size of the bored hole shall be of such diameter to provide ample clearance for bells or other joints. The holes are to be bored mechanically. The boring shall be done by using either a pilot hole or a dry bore method.

2. A pilot hole boring shall be constructed by the following method: An approximate 2- in.

(5cm) pilot hole shall be bored the entire length of the crossing and shall be checked for line and grade on the opposite end of the bore from the work pit. The pilot hole shall serve as the centerline of the larger diameter hole to be bored.

3. The dry bore shall be constructed as follows: The casing pipe shall be advanced as the soil is removed by augers. Bentonite may only be used as a lubricant. Casing shall be new or used steel conduit approved by the OWNER, with a minimum inside diameter sufficiently larger than the outside diameter of the carrier pipe or ducts to accommodate placement or removal.

4. All carrier pipe installed by boring shall be supported by a quarter point cradle of Class B or Class PB concrete as specified by the OWNER across the boring pit and to the first joint in the ditch section on each end. All pits should have crushed rock and sump areas to remove water. Where groundwater is found, pits shall be lined with filter fabric.

5. All voids shall be grouted per ASTM C476 Grout for Masonry and shall be considered a part of the unit price of the boring operation.

6. In addition to the requirements stated above, the applicable provisions above.

Construction by Jacking in regard to the construction of trench, tolerance in line and cradle, method of operations, backfilling, etc. shall govern for construction by boring.

D. Construction by Guided Boring or Directional Drilling: Guided boring or directional drilling shall be accomplished according to the standards in Trenchless Technology Guidelines published by the International Society for Trenchless Technology.

E. Construction by Tunneling:

F. The tunnel shall be excavated in such a manner and to such dimensions so as to permit placing of the proper supports necessary to protect the excavation. The CONTRACTOR shall take the proper precautions to avoid excavating earth or rock or shattering rock beyond the limits of excavation shown on the plans. All damages caused by excavating and blasting, either to surface or subsurface structures, shall be repaired or replaced by the CONTRACTOR at its own cost and expense. Adequate provisions shall be made for safety and health of the workers.

All equipment operated in the tunnel shall be powered by either air or electricity. No equipment shall be permitted in the tunnel that uses a petroleum product such as fuel.

1. Electric lights shall be used for illumination of completed portions of the tunnel used for passage and wherever lighting is needed for inspection of the work. A sufficient number of lamps shall be used to properly illuminate the work, and all wiring for electric power and lights shall be installed and maintained in a safe and secure manner in accordance with the current applicable electrical specifications of the OWNER. CONTRACTOR shall maintain the tunnel air in a condition suitable for the health of the workers and sufficiently clear for surveying operations. A sufficient supply of fresh air shall be provided and maintained at all times in all underground places. Provisions shall be made for the quick and complete removal of gases and dust resulting from blasting or other tunnel operations. Except when unnecessary due to natural ventilation, artificial ventilation shall be maintained in the tunnel by ventilating plants of ample capacity operated when needed to meet the preceding requirements.

2. If required for safety, suitable steel or timber sheeting, shoring and shall be used to support the sides and roof of the excavation. When the installation is completed, and if approved by the OWNER, supports may be left in place, provided that they clear the encasement or carrier pipe. No separate payment shall be made for supports left in place.

Nothing contained herein shall prevent the CONTRACTOR from placing such temporary or permanent supports as it shall deem necessary, nor shall anything contained herein be construed as relieving the CONTRACTOR from its full responsibility for the safety of workers and for all damages to personal property caused by its operations.

3. If the tunnel is to be lined with concrete as a monolithic structure, then the overbreak, if any, or voids shall be poured with Class A or Class PA concrete as specified by the OWNER. The CONTRACTOR shall not be compensated for overbreaks.

4. No pipe shall be placed until the foundation is in a condition satisfactory to the OWNER.

Tunnel dimensions shown on the plans are minimum dimensions. Any excess excavation and subsequent backfill, concrete or grout fill shall be at the expense of the CONTRACTOR. The pipe shall be laid in the tunnel true to line and grade. Tolerance in line and grade shall be as specified above. Construction by Jacking.

5. If indicated or specified, the entire void between the outside of the pipe and the tunnel walls or the inside face of the tunnel lining shall be grouted per ASTM C476 Grout for Masonry unless the permanent sheeting, bottom, sides and roof of the tunnel are in a condition satisfactory to the OWNER. The minimum thickness of grout backfill where specified shall be maintained throughout. Grout required for backfill in excess of the minimum dimensions shown on the plans shall be at the entire expense of the

CONTRACTOR.

6. All pipe damaged during construction operations shall be removed and replaced by the CONTRACTOR at the CONTRACTOR’S entire expense.
