1 ADDENDUM #2 September 14, 2018 PROJECT: Virginia Polytechnic Institute & State University, Blacksburg, Virginia Perry Street Steam System Improvements IFB: Changes and Clarifications - General 1. See attached non-mandatory prebid meeting Sign-in Sheet (1 page). 2. See attached non-mandatory prebid meeting Agenda (1 page). Response to Bidder Questions 1. The Perry Street Specifications call for copper wire leak detection. Mechanical Pipe Systems supplies a 2 wire system, which all pre-insulated pipe manufacturers can buy since it is made in Germany. It is a true leak detection for 100% of the line. The copper wire by other companies is only on the straights, and at all potential leak areas (elbows, anchors, end seals) where you need protection, they supply a coated copper wire that cannot detect an event if water gets to steel conduit. Is this what the owner wants for this project? Response: Per discussion with Virginia Tech, a leak detection system shall not be provided per Specification Section A dryness test has been added to the scope of the project as follows. Upon completion of the underground steam and condensate conduit system, the installing contractor shall perform a system dryness test. The outer conduit shall have -20 degrees F or lower membrane or desiccant dry compressed air at the required SCFM based on conduit size in one end of the conduit. Contractor shall ensure the outer conduit is not over pressurized and all safety measures are taken. The dew point shall be read using a dew point meter and should not exceed +20 degrees at the opposite end of the conduit system. If the dew point temperature exceeds +20 degrees F the contractor shall proceed with the conduit manufactures drying procedures. All tests shall be from each isolated section of the system. Each section tested shall be witnessed by the pipe manufacture or their representative, engineer and/or owners representative. A report shall be provided and signed by the installing contractor stating the system has been tested successfully. 2. The Notice of Invitation For Bid form states that contractors shall provide a detailed schedule with their bids. In order for that to be completed, a list of dates and times that work can be done in certain areas is needed. A list of days and times when work will be restricted is also needed. A phasing plan (if the job cannot be completed in one mobilization) is needed to determine where additional mobilization will need to be completed. Response: The contractor shall prepare a work plan to conform to all of the notes and details included in the project documents. This also includes specific notes regards pedestrian and vehicular traffic as included on Plan Sheet C3.01 Pedestrian and Traffic Control Plan. At this time, there are only two work restrictions during the construction period of November 11, 2018 through May 31, No work is allowed to be done between December 6, 2018 and December 14, 2018, and between May 9, 2019 and May 18, 2018.

2 Connections to the high pressure steam cannot be completed until the existing system is shutdown. The scheduled shutdown of the system will be from May 19, 2019 through May 26, Specification Section A2 states that an independent testing firm shall be used in radiographic testing. Is it acceptable to use ultrasound testing in lieu of radiographic testing? This method is being proposed for the following reasons: a. Radiographic testing will require a 60 foot radius clear distance all around the testing area. No personnel or vehicle traffic of any kind is allowed during testing. Testing will take approximately 1 hour per weld with multiple welds being completed during a test session. b. The companies that perform radiographic testing have limited RT certified technicians, and they are already committed to other jobs extending into next year. Ultrasonic testing technicians are more available and can meet the construction schedule. Ultrasound testing is an equal to radiographic testing and does not require clearing the area during testing. Response: No exception is taken to the use of ultrasonic testing. Ultrasonic testing shall meet ASME B Specification Section A calls for a steam blow for steam piping. Due to the location of the underground piping system a steam blow would not be practical. With the available steam at manhole 5, the distance would not give enough steam pressure. Per Specification Section B, the condensate will be flushed with water for cleaning. Can the steam piping be cleaned like the condensate? Response: Contractor shall bid the project per the specifications. Changes and Clarifications to Front End Documents 1.
