PART 3– EXECUTION 3.1

DELIVERY AND OFF-LOADING A.

All pipe shall be bundled or packaged in such a manner as to provide adequate protection of the ends during transportation to the site. Any pipe damaged in shipment shall be replaced as directed by the Owner’s Representative.

B.

Each pipe shipment should be inspected prior to unloading to see if the load has shifted or otherwise been damaged. Notify Owner’s Representative immediately if more than immaterial damage is found.

C.

Each pipe shipment should be checked for quantity and proper pipe size, color and type.

D.

Pipe should be loaded, off-loaded and otherwise handled in accordance with AWWA M23.

E.

A forklift with chisel forks shall be used to off-load the pipe. The fork chisel should be checked to be sure it is not thicker than the gap between the units of pipe strapped together for shipping and handling purposes. Extend forks to remove each top unit from the truck. When unloading 20’ lengths, remove back units first. Do not run forks too far under the units, as fork ends striking adjacent units may cause damage. Ensure that the forks are fully engaged. The 30’ and 40’ lengths are shipped in single length units. Because these are longer, the packages will flex or bend more than the 20’ length units. If left bundled in units,

2015 SWAP CAPITAL PROJECTS BID PACKAGE F - RECYCLED WATER PIPELINES

FUSIBLE PVC PIPE 15294 – Page 8 of 16

SECTION 15294 – FUSIBLE PVC PIPE unloading can be done with a single forklift so long as it is of sufficient capacity to handle the load. If sag exceeds recommendation (see the table below as to allowable sag), then each piece of pipe should be unloaded individually. The forks should be placed as far apart as possible to provide support to the unit. When unloading individual pieces of pipe, the pipe should be supported at approximately the 1/3 point measured from each end of the pipe.

40’ Length 24 16 13 10 9 7 5 4 3

30’ Length 14 10 7 6 5 4 3 3 2

F.

Sag is the measurement of the pipe ends relative to the pipe center. With a pipe raised on the forklift, a string line can be pulled from the bottom of one end of the pipe to the bottom of the other end of the pipe. The distance in the center from the string to the bottom of the pipe is the sag.

G.

If a forklift is not available, a spreader bar with fabric straps capable of handling the load should be used. Recommended lift points when using fabric slings are at the point approximately one-third of the length measured from each end of the unit.

H.

Off-loading devices such as chains, wire rope, chokers, or other pipe handling implements that may scratch, nick, cut, or gouge the pipe are strictly prohibited.

I.

During removal and handling, be sure that the pipe does not strike anything. Significant impact could cause damage, particularly during cold weather.

J.

If appropriate unloading equipment is not available, pipe may be unloaded by removing individual pieces. Care should be taken to insure that pipe is not dropped or damaged.

K.

Pipe should be carefully lowered, not dropped, from trucks.

L.

In preparation for pipe installation, placement of pipe should be as close to the fusion area as practical.

HANDLING AND STORAGE A.

Any length of pipe showing a crack or which has received a blow that may have caused an incident fracture, even though no such fracture can be seen, shall be marked as rejected and removed at once from the work. Damaged areas, or

2015 SWAP CAPITAL PROJECTS BID PACKAGE F - RECYCLED WATER PIPELINES

FUSIBLE PVC PIPE 15294 – Page 9 of 16

SECTION 15294 – FUSIBLE PVC PIPE possible areas of damage may be removed by cutting out and removing the suspected incident fracture area. Limits of the acceptable length of pipe shall be determined by the Owner’s Representative. B.

Any scratch or gouge greater than 10% of the wall thickness will be considered significant and can be rejected unless determined acceptable by the Owner’s Representative.

C.

Pipe lengths should be stored and placed on level ground. Pipe should be stored at the job site in the unit packaging provided by the manufacturer. Caution should be exercised to avoid compression, damage, or deformation to the ends of the pipe. The interior of the pipe, as well as all end surfaces, should be kept free from dirt and foreign matter.

D.

Pipe shall be handled and supported with the use of woven fiber pipe slings or approved equal. Care shall be exercised when handling the pipe to not cut, gouge, scratch or otherwise abrade the piping in any way. Use of hooks, chains, wire rope or any other handling device which creates the opportunity to damage the surface of the pipe is strictly prohibited.

E.

After delivery to the project site, fusible polyvinylchloride pipe shall be stored at ambient temperature and protected from ultraviolet light degradation. If pipe is to be stored for periods of 6 months or longer, the pipe must be shaded or otherwise shielded from direct sunlight. Covering of the pipe which allows for temperature build-up is strictly prohibited. Pipe should be covered with an opaque material while permitting adequate air circulation above and around the pipe as required to prevent excess heat accumulation.

F.

Racks or dunnage to prevent damage to the bottom of the pipe during storage should support the pipe lengths. Supports should be spaced to prevent pipe bending and deformation. The pipe shall be stored in stacks no higher than that given in the following table: Pipe Diameter (inches) 8 or less 12 to 21 24 to 30 33 to 48 54 and larger
