Date Issued: October 23, 2014

ADDENDUM NO. 1

This addendum will only be distributed via e-mail, but will remain available for viewing on the MSDGC website at www.MSDGC.org on the project-specific web page. No hard copy will follow. NOTE: Please be sure to enter the TOTAL NUMBER of Addenda issued on the ‘Official Bid Form’ contained in the Bid Document prior to submitting your bid. The attention of all bidders is directed to the following additions and/or deletions to the Contract Documents. ►ADDED ITEMS◄ ARE UNDERLINED AND DELETED ITEMS ARE STRUCK THROUGH The Contract Documents for the above referenced project are amended and revised as follows: 2nd FACILITY TOUR OPPORTUNITY MSDGC will hold one additional guided tour of the DIW facilities on Monday, 10/27/2014 at 10:00 AM ET. Participants should gather in the atrium of 1081 Woodrow Avenue. This tour will be a repeat of the tour given at the Pre-bid meeting on 10/21/2014. Pre-registration is not required. QUESTIONS & ANSWERS Question A: Regarding the replacement of the Fume Hood Sashes and Liner Material, can you provide the name and contact information of the current manufacturer, and what type of liner is currently being used? Since that manufacturer may be adverse to supplying product and material to a competitor, would the Owner or the CM consider providing the material, and the contractor do the installation? If we wait until the Pre-bid Meeting, there may not be enough time to acquire pricing from the current manufacturer. Photo would also be most helpful in determining what needs to be considered in this scope of work. Answer A: The existing laboratory casework was manufactured by BMC National Products, PO Box 4089, Muskegon Heights, MI 49444. (616) 733-1206. The attached file contains the original product data submittal for the existing fume hoods. The attached photo shows FH-23. Question B: You may want to ask for an Alternate to replace the fume hoods, as opposed to replacing the sashes and liners. Newer hoods could be run at lower CFM / FPM, giving the users significant long term energy savings. Answer B: We are unable to change the budget, the scope of the project or the bid items at this time. Question C: I am requesting adding Hanson Lab Furniture to the list of Approved Manufacturers in Spec. Section 115313. 2. 1. A., and Hanson and Wood-Metal Industries be added to the list of manufacturers

listed in Spec Section 123533.2.5.A. See attached substitution form, and data regarding Hanson and Wood-Metal Industries.

voice cabling be considered?   A. Yes, all voice jacks and cabling are being retained. See Keynote 5 on ED101. The project should be bid as

those areas? 

Pre‐bid Meeting Report October 21, 2014 Page 3

  A. All walls (new and existing) unless otherwise noted, extend to the underside of the floor or roof deck above. First floor to second floor height is 14’‐0”. Distance from second floor to underside of the roof deck is approximately 15’‐0”. Ceiling heights are indicated in the Room Finish Schedule on A‐701 and in details on A‐501. For additional ceiling heights, see also the Room Finish Schedule on Sheet A2.4 of the Original Construction Drawings which can be accessed through the MSD website. 

 3.4   Q. Is any of the electrical power distribution wiring located in the floor slab?   A. None of the wiring is in the slab.  3.5   Q. Are the existing office systems furniture panels electrified?   A. No, they are not. There is no wiring in the panels.  3.6   Q. Will MSD furnish protective pads for the elevator?   A. Contractor use of the elevator is permitted, as described in Specification Section 01 50 00 Temporary 

Facilities and Controls, paragraph 3.3.C. In this paragraph the contractor is directed to provide protective coverings. 

 3.7   Q. Is the roofing system under warranty?   A. Specification Section 07 01 51 Roofing Protection and Repairs describes the existing roofing system, which 

was installed in 1994, in detail. It also includes requirements for the roofing system manufacturer to approve the materials and details to be used in roofing repairs and new work. There are no requirements to maintain a warranty in effect. 

 3.8   Q. Can the exhaust fans in the penthouses be temporarily taken out of service and moved if needed to 

provide clearance for the work at the air handling units?   A. In general, it is acceptable to temporarily remove the exhaust fans from service since the fans in each 

penthouse most likely serve fume hoods in the same area that is served by the air handling unit.  However, the contractor is to confirm this. Note that each exhaust fan number corresponds to the fume hood served by that fan. For example, exhaust fan F‐23 serves fume hood FH‐23.
