DESCRIPTION
Q1
How deep should the trench for underground piping be?
A1
Please refer to pipe profile on M-100 (POC is around 8’ below grade) and details
6/M-500 and 7/M-500 for trench size and depth (minimum 3’-0” to top of pipe
under roadway). Contractor has the option to run at deep as shown in profile or
rise piping while maintain the minimum cover. Offsets and anchor locations shall
be accordance with ASME B31.1 thermal stress analysis provided by the
Contractor.
Q2
What is the depth of the Vault, and do you have any specs on the vault?
A2
Please refer to detail 4/M-501 for minimum vault size. Vault shall be Oldcastle
Precast or equal with cast iron vault lid H20 rated for vehicle traffic. Depth shall be
between 4’ to 5’ below grade as shown on profile M-100 for vault in the street.
Vault can be open on bottom with 12” deep pea gravel. Provide ladder or built-in
steps for vaults over 3’ deep.

Project No.: 5109218
Contract No.: 999027
Q3
Is there a U/G piping spec for the HTW routing underground as shown on M-100
A3
No. Underground and above ground high temperature water piping requirements
are included in specifications 23 2400. Piping shall be ASTM A106. Type S,
Grade B, schedule 40 welded by certified welders for ASME B31.1 Power
Pressure Piping. Piping shall be field insulation as specified in section 23 0700. A
few items worth noting include:
- underground high temperature pipe shall be as specified in 23 2400 - 2.03
- underground high temperature pipe shall be insulated with 4" cellular glass with
two layers of Pitt wrap, as specified in 23 0700 - 3.17
- underground high temperature pipe shall be radiographed as specified in 23
2400 - 3.03 - B - 12
Welding shall be keep to a minimum by using 40-foot pipe lengths and using of
pre-bent piping offsets.
Regarding detail 4/S-001 – Note reads “¼” thick A36 bent plate galvanized and
painted Typ”
Q4
¼” sound excessive and will be very heavy. Each 1 square foot for ¼” plate
weighs about 11 lbs. If we are to build 4 foot section, we will have a minimum of
337 lbs. per section. Are we to hold 337 lbs. with only ¼ Hex bolts? The total
weight of the steel plate will be about or more than 6,000 lbs. on the side of the
building.
In-order to install these plates we will need a crane for each section. We will need
lifting lugs. These lifting lugs will show and will need to stay just in-case someone
needs to service the pipe.
How are we attaching each section to the next? Is it flanged? Is it welded?
A4
VI.
The requirement for ¼” plate shall be deleted. Structural enclosure is not required.
Please provide an Architectural sheet metal pipe chase in accordance with Section
07 6200, “Sheet Metal Flashing and Trim” issued with this addendum to conceal
the piping.
