full extent of the changes is detailed below.
1) Sheet 7 of the Plans (Dwg No. P01), Preparations Keynotes

page 117 of special provisions shall include the following.

Questions/Clarifications
1. Will the City accept MJ fittings and restrained retainer glands (Megalug or approval equal) for ductile
iron fittings for this project?
Answer: The City will allow the use of mechanical joint (MJ) fittings and restrained retainer
glands (e.g., Megalug or approved equal), provided they meet the conditions outlined in
Project Special Provisions Section 9-30.2(6).
2. For the DI Long Body Sleeves called out for connecting to existing DI pipe, are DI Mechanical Joint
Long Sleeves and Mega-Lugs acceptable?
Answer: The use of mechanical joint (MJ) long sleeves and Mega-Lug restrained glands is
acceptable for the ductile iron (DI) long-body sleeves specified for connections to existing DI
pipes.
3. Please define Restrained Joint (RJ) fittings. Are TR Flex fittings required on this project or will MJ
fittings with Mega-Lugs be accepted?
Answer: Restrained-Joint Fittings are defined as mechanical joint fittings with restrained
retainer glands (equal to Megalug 1100 Series, or Romac Romagrip, or Star National Products
Series 3000 Stargrip).
TR Flex fittings are not required on this project. MJ fittings with the above restrained retainer
glands are approved as “restrained-joint fittings”.
4. Regarding Spec 9-30.2(6), I want to confirm that the Pipe will be Boltless R.J. such as TR Flex, and
that Fittings and Valves with Wedge Restraint Glands will be acceptable?
Answer: TR Flex is acceptable as a restrained-joint pipe, MJ fittings with the above restrained
retainer glands are approved as “restrained-joint fittings”.
5. We have a question regarding Bid Items - C37, C38. These bid items refer to City of Renton
Standard Plan 320.2, Mainline tee with 2” tapped reducing tee MJ X FIPT. This tee is not
manufactured as a restrained joint fitting with boltless restraint. One option, Mainline tee MJ X
FIPT Tee with restraining glands (Megalug). Another option would be a Romac service saddle
with FIPT outlet. Can you please confirm what the city will allow for these Bid items?
Answer: Standard Plan No. 320.2 specifies a 2-inch tapped reducing tee (MJ x FIPT). Based on the
project plans and Special Provisions, all mechanical joint fittings (MJ) are required to include
Highlands Reservoir Water Main Improvements Project ADDENDUM NO. 2
Page 3 of 3 March 20, 2026
restrained retainer glands. Therefore, a mainline tee (MJ x FIPT) equipped with restraining glands
(e.g., Megalug) would meet the project’s Special Provisions.
6. Can the City provide some more information about the existing vault?
Answer: For the existing vault located at the northwest corner of the Edmonds Ave NE
and NE 12th St intersection, the City does not have as-built or record drawings on file. It
shall be the responsibility of the prospective bidder or contractor to verify the vault type,
dimensions, and coordinate with suppliers to furnish a new vault lid in accordance with
the contract documents.
ALL OTHER REQUIREMENTS OF THE CONTRACT PROVISIONS REMAIN IN EFFECT.

Project Manager, City of Renton
