B. Refer to additional definitions under Section 2.2 Materials:

1.4 Quality Assurance
A. Use adequate numbers of skilled workmen trained and experienced in necessary trades and crafts and completely familiar with specified requirements and methods for proper performance of Work of this section.

B. Provide adequate equipment and methods to accomplish earthwork in accordance with applicable grading codes and ordinances, Contract Documents, and recommendations in accepted geotechnical report(s) and grading plan(s).

C. City has hired a Geotechnical Engineer to oversee earthwork, perform laboratory and field tests, and verify compliance with recommendations from Geotechnical Report and Contract Documents.

1. During grading and earthwork, Geotechnical Engineer will observe, map, and document subsurface exposures to verify geotechnical design assumptions.

2. If observed conditions materially differ from interpreted assumptions during design, Geotechnical Engineer will inform City, recommend appropriate design changes to accommodate observed conditions, and notify review agency where required.

3. Subsurface areas to be geotechnically observed, mapped, elevations recorded, and/or tested include natural ground after being cleared for receiving fill, but before fill is placed, bottoms of "remedial removal" areas, key bottoms, and benches made on sloping ground to receive fill.

4. Geotechnical Engineer will observe moisture-conditioning and processing of subgrade and fill materials and routinely test relative compaction of fill.

5. Geotechnical Engineer will provide test results to City and Contractor.

6. If, in opinion of Geotechnical Engineer, unsatisfactory conditions, such as unsuitable soil, improper moisture condition, inadequate compaction, insufficient buttress key size, adverse weather, etc., are resulting in a quality of Work less than required in these specifications, Geotechnical Engineer will reject Work and may recommend to City that construction be stopped until conditions are rectified.

PART 3 - EXECUTION

3.1 Preparation
A. Pipe and other underground improvements may or may not be shown on Plans.

1. Preserve and protect such improvements whether shown or not.

2. Refer to Section 31 05 50 for requirements for protecting existing utilities

3. Where necessary to remove and replace or to relocate such improvements to prosecute Work, improvements shall be removed, maintained, and permanently replaced by Contractor at their expense, except as otherwise provided in Contract Documents.

4. California Government Code §4216 states Contractors “planning to conduct any excavation shall contact the appropriate regional notification center at least two working days but not more than 14 calendar days, prior to commencing excavation.” B. Control surface drainage and prevent surface water from entering excavations as follows:

1. Control grading to prevent water running into excavations.

2. Maintain feathered edges of asphalt around trench plates.

3. Do not obstruct surface drainage away from receiving watershed. a. Intercept and divert runoff around Work using temporary slopes, sand bags, dikes, swales, levees, curb walls, drainage ditches, gutters, sumps, drains or other means of channeling flow without interruption around excavations.

4. Preserve existing drainage patterns except as otherwise shown. a. Where construction methods cause temporary obstruction of drainage patterns, provide temporary facilities adequate for expected flows and a means of emergency removal of obstruction.

5. Design surface drainage system to minimize erosion on or off site.

6. Dispose of water in suitable manner without damage to adjacent property. a. Do not drain water into Work built or under construction without prior consent of City’s Representative.
b. Dispose of water according to permits and in such manner as not to be a menace to public health and public or private property.

C. Refer to Section 31 23 19 for requirements for dewatering.

1. Commence dewatering for structures and pipelines when groundwater is first encountered.

2. Continue dewatering until water can be allowed to rise in accordance with provisions of Section 31 23 19.

D. Remove and reconstruct asphalt paving improvements per Section 02 41 14 and 32 12 16.

E. Remove and reconstruct concrete paving improvements per Section 02 41 14 and 32 13 13.

F. Preparation for fill shall proceed as follows:

1. Clear and grub areas to receive fill or embankment per Section 31 10 00.

2. Scarify areas to receive fill to ≥6” to provide a bond between existing ground and fill material to be deposited thereon.

3. Moisture condition scarified areas and compact to ≥85%. 1-22-dp

4. When fills are to be placed over existing surface improvements to remain in place cut 4” drainage holes through structure or paving at 5’ centers each way, or break or saw-cut pavement in grid pattern of 5’ each way with minimum ¼” gap between broken sections.

G. Blasting shall be prohibited

3.3 Field Repair Methods
A. Repair mortar coating and lining defects as follows:

1. Remove and replace material lacking uniformity, exhibiting segregation, honeycombing, or lamination, or containing dry patches, slugs, voids, or sand pockets.

2. After cutting or abrasive blasting, wet surfaces sufficiently in advance of shooting so while repair material is being applied, surfaces under repair remain moist but not so wet as to prevent adhesion and good bond.

3. Remove mortar to pipe wall in areas where quality is defective, such as sand pockets, voids, oversanded areas, blisters, drummy areas, cracked areas, and thin spots.

4. When removing defective mortar, cut back material to square shoulder. a. Do not feather-edge joints.

5. Do not hand-patch.

6. If defective lining is removed and pneumatically reapplied, mortar lining shall be reinforced.

7. Replace with pneumatically applied mortar to full required thickness.

8. Do not begin scraping or cutting to remove high spots until mortar is stiff enough to withstand pull of cutting device.

3.4 Protection
A. When pipe laying is not in progress, and during noon hour and overnight, close open end of pipe with tight-fitting cap or plug to prevent entrance of foreign matter into pipe.

B. Do not use pipeline to drain water which has infiltrated into trench.

C. Maintain inside of pipe free from foreign materials and in clean and sanitary condition until acceptance by City.
