Pr oject Considerations for Pipe Replacement Methods 249

• Pipe materials and manhole considerations
• Standards and tolerances for pipe material, wall thickness
and class, testing and certification requirements
• Construction installation instructions for pipe joining and
handling
• Fittings, appurtenances, and connection-adaptors
• Acceptable material performance criteria and tests
• Construction considerations
• Flow bypassing, downtime limits, and service reinstate-
ment requirements
• Spill and emergency response plans
• Traffic control requirements
• Erosion and sediment control requirements
• Existing conditions documentation (e.g., photographs,
videos, interviews)
• Protection plan for existing structure and utility (ground
movement monitoring)
• Accuracy requirements of the installed pipe
• Daily construction monitoring reports
• Field testing and follow-up requirements for pipe joining,
pipe leakage, disinfection, backfill, and others
• Site restoration and spoil material disposal requirements

6.8.9 Submittals
In addition to the submittals needed for a traditional open-cut proj-
ects, the submittals for pipe-bursting projects usually include the
following: site layout plans, sequence of bursting, shoring design
for all the excavations signed by a professional engineer, bypass
pumping plan, manufacturers’ specifications of the selected burst-
ing system and its components, dewatering plan, new pipe mate-
rial, lateral connections material and plans, contingency plans, and
the like. The site layout plans would show the location of the inser-
tion and pulling shafts, dimensions of shafts, traffic flow, safety and
communication plan, storage space to store and lay the new pipe,
and the like. Site restoration and clean-up plans should also be
included in the submittals.

6.8.10 Quality Assurance/Quality Control Issues
The project specifications should state the quality assurance (QA)
and quality control (QC) measures required to ensure that the project
is executed according to the contract specifications. In addition to the
