About this file
This document contains project clarifications for a sewer line construction or infrastructure project. The clarifications address four key technical details: (1) pipe bedding material specifications require Type 1 Bedding of imported sand, sandy crushed gravel, or crushed gravel with specific size and plasticity constraints, (2) existing manhole tie-in depths are approximately 3.5 and 6.5 feet deep based on horizontal gridline increments, (3) concrete encasement for a clean out can be poured in a thrust block style, and (4) the job site contains multiple mature trees, with one tree near a project line potentially requiring removal if it interferes with construction.
The accompanying image depicts a wooded site with a wooden building, showing a green-marked path leading to a red-circled ground feature (likely the manhole or infrastructure point of interest), surrounded by pine trees and grassy terrain. The image appears to be documenting the actual project location referenced in the clarification document.

Clarifications:
1. What type of material do they want for the pipe bedding? Would reject material be suitable for pipe bedding?
Provide Type 1 Bedding consisting of imported sand, sandy crushed gravel, or crushed gravel having a maximum 3/4-inch size (19mm), maximum 10% passing the #200 sieve, and a maximum plasticity index of 6, determined by AASHTO T89 and T90 or by ASTM D4318.
2. How deep is the existing manhole tie in point? It does not specify on the plans.
The horizontal gridlines on the sewer line profiles indicate 1-foot increments. One invert is approximately 3.5 ft deep and the other is approximately 6.5 ft deep.
3. On the concrete encasement on the clean out, can I pour it as a thrust block style or do I need to form it?
Thrust block style is acceptable.
4. Please be advised that there are many mature trees present throughout the job site, 1 has been identified as likely to have roots present near one of the lines and may need to be removed by the contractor if it interferes.
