PART 3 – EXECUTION

3.01 GENERAL

A. Ground Water

1. All ground water shall be kept away from newly poured concrete until concrete has properly set, and a watertight job is obtained. Manholes which admit ground water after completion, must be repaired to the satisfaction of the

Owner.

B. Line and Grade

1. Where manholes occur in pavements, set top of frame and covers flush with finished surface (not necessarily level). Where manholes occur in dirt roads, set top of frame and cover 6 inches below finished surface. Elsewhere set top of frame and cover 3" above final grade, unless otherwise indicated.

02510-7 PN: 502100708

2. Care shall be taken to have all pipes to and from manholes laid to correct lines and grades as established for the project.

C. Drop Manholes

1. Where shown, drop manholes shall be constructed in accordance with the details shown on the Drawings.

3.02 PRECAST MANHOLES

A. Handling

1. All precast manhole components shall be lifted and moved by use of lifting eyes that are slipped into the insert which are cast into the manhole. The lift system shall not damage the precast manhole.

2. All damage to precast sections shall be thoroughly repaired in the presence of the Owner’s representative. Repair and patching of minor breaks shall be done by chipping and scarifying the defective area before application of grout.

Sufficient time shall be allowed for curing before the precast sections are joined. Cast-in-place concrete bases shall be specially formed and keyed to accommodate the bottom precast section.

B. Site Inspection of Precast Sections

1. Precast sections not conforming to any of the specification requirements shall be rejected. In addition, individual manhole sections may be rejected due to any of the following:

a. Fractures or cracks passing through the wall, except for a single end crack that does not exceed the depth of the joint.

b. Defects that indicate imperfect proportioning, mixing, and molding.

c. Surface defects indicating honey-combed or open texture.

d. Damaged or cracked end, where such damage would prevent making a satisfactory joint.

e. Any continuous crack having a surface width of 0.01 inch (0.25 mm) or more and extending for a length of 12 inches (305 mm) or more, regardless of position in the section wall.

C. Bitumastic Coating (Outside Only)

1. Prior to setting the precast sections in place each section shall have the exterior concrete surface blown free of all dirt and debris and brushed clean and then coated with bitumastic. As an alternative, the bitumastic coating may be applied at the manufacturer's plant in accordance with this Specification.

2. The coating shall be Bitumastic 50 as manufactured by Carboline Co., or equal.

3. At least three coats shall be applied giving a total minimum dry film thickness

(DFT) of 32.0 mils.

4. After installation, damaged surfaces including plugged lifting holes, shall be recoated in accordance with the coating manufacturer's recommendation to give the required minimum 32.0 mils DFT.

5. The Contractor shall provide a certification to the Owner stating that he has installed the exterior manhole, wetwell and valve chamber coatings in

02510-8 PN: 502100708

accordance with the manufacturer's recommendations, and that there is a minimum 32.0 mils DFT of material on all component structures.

D. Placement

1. Manhole sections shall not be set by wedging or placing shims to secure proper level and manholes shall not be backfilled without the approval from the Owner.

E. Masonry Work

1. The top of all precast manholes may be brought to proper grade for receiving manhole frames after paving has been replaced on paved streets by using

HDPE plastic rings, traffic rated. In lieu of the HDPE plastic rings, precast manholes may be brought to grade by the use of no more than two precast concrete extension rings. The total depth of the rings shall not exceed 6 inches. The construction shall be performed by experienced and qualified laborers only. All work shall be laid plumb, straight, square and true. Where manholes are installed in areas with sloped pavement, the manhole ring and cover shall be set flush and in the same plane as the finished surface (not level). Rings shall be laid in full beds of mortar necessary to ensure cover is flush with finished pavement surface. All joints shall be full and not more than

1/2 inch in thickness. The Contractor shall set in place and bond in the masonry all necessary steps and miscellaneous items specified elsewhere.

The masonry walls shall be parged on the outside with a one-half inch coat of

Portland cement mortar.

2. All mortar shall be a mixture of non-shrink grout.

3. Masonry shall not be constructed during cold weather (air temperature below

40 deg. F) unless necessary precautions are observed as permitted by the

Owner.

4. Concrete collar, to be constructed around frame and cover after adjustment.

Concrete strength shall be 3,000 psi.

3.03 FLOW CHANNELS AND BENCH WALLS

A. The method of constructing flow channels and bench walls is dependent on which manhole base (i.e. manhole, wetwell, or valve chamber) has been installed.

B. In precast bases, the flow channels and bench walls in each manhole shall be carefully formed of mortar and concrete. Precast inverts will not be accepted unless specifically approved by the Owner.

C. The minimum depth of flow channel shall be equal to 3/4 the diameter of the largest sewer in the manhole to which it connects. The channel shall be graded to give a smooth, uninterrupted flow through the manhole.

D. Bench walls shall be pitched a minimum of 1 inch but not more than 2 inches per foot from the inside periphery of the manhole to the edge of the flow channel.

3.04 TESTING

02510-9 PN: 502100708

A. Manholes shall be constructed to be completely watertight. The contractor shall test the manhole by one of the following methods:

1. Infiltration Test: If the manhole is located below the groundwater table, the inverts shall be plugged and the infiltration into the manhole shall be measured after a 24-hour period. If any visible infiltration has occurred into the manhole, visible by wet walls or any accumulation on the bench, the infiltration shall be considered excessive.

2. Exfiltration test: If the manhole is above the current groundwater table, an exfiltration test will be conducted. All incoming sewer lines shall be plugged and the manhole filled with water to a level above the highest section joint and allowed to stand for three hours to compensate for potential absorption by dry concrete. After the soaking period, water shall be added as required to raise the water to a level that is above the highest joint section. If the water level drop exceeds 1/8” per vertical foot of manhole depth in 24 hours, the manhole shall have failed the test.

B. As an alternative to infiltration and exfiltration test, concrete sewer manholes could be tested in accordance with test procedure described in ASTM C1244.
