QUESTIONS AND ANSWERS

The purpose of this amendment is to extend the Bid Opening Date, provide an additional site visit, correct information on the photos posted in Amendment 0001 and to provide questions and answers. Please acknowledge this amendment in your bid.

A. SOLICITATION RESPONSE DATE

1. The Bid Opening Date for this requirement is being extended to 3 September 2014 no later than 2:00pm CST.

B. SITE VISIT

1. Another site visit will be scheduled. Information on this site visit will be posted next week via an amendment. Please continue to check www.FBO.gov for details.

C. CORRECTION

1. In regards to pictures posted from previous amendment. Pictures 3_2-7 should be omitted. The ducting in these pictures IS NOT to be removed.

D. QUESTIONS AND ANSWERS

Question 1: Solicitation item # 0002, 0003 notes boiler 3 & 4 to remove ash hopper though no drawings are found that indicated in the SOW to remove ash hopper from Boiler 3 & 4. Is the ash hopper of boilers 3 & 4 the same as boiler #2? Please advise or confirm.

Answer 1: Note drawings M1 and M3 for ash hopper 3 & 4 details. If options 1 & 2 are awarded then boiler 3 & 4 ash hopper will be removed. Ash hopper 3 & 4 are identical to ash hopper 2.

Question 2: Please extend the project bid date 10 additional working days.

Answer 2: AF PM is ok with bid due date extension.

Question 3: Reference drawing M3, Boiler #2 Demolition notes #9: By this note it is assumed that a plate exists in the bottom of the boiler at the ash hopper. The SOW is only to insulate after the ash hopper is removed. Please confirm.

Answer 3: See demolition notes on M1. With unknown conditions of the plates, a modification would be completed if work required was greater than what is listed in the spec. We spec that the plates will be insulated after the ash hopper is removed and if minor holes exist they will be patched/sealed.

Question 4: Drawing M5, Detail G/M5, Drawing M7 Installation note 7, at top of duct transition piece to existing F.D. Ductwork: This dimension to the existing duct is not found in the drawings/bid docs. What is the dimension of this existing ductwork so the connective transition part can be sized and priced correctly?

Answer 4: See drawing M6 for table titled Expansion Joint Schedule, Boiler 2.

Question 5: Drawing M8, Detail F/M8, at top of duct transition piece to existing Ductwork:

This dimension to the existing duct is not found in the drawings/bid docs. What is the dimension of this existing ductwork so the connective transition part can be sized and priced correctly?

Answer 5: See drawing M6 for table titled Expansion Joint Schedule, Boiler 2.

Question 6: Drawing M8, Detail 4/M8. Detail of duct wall notes a angle iron stiffener. What is the material size, type of material and requirements where to be use of this stiffener? Please advise.

Answer 6: Duct stiffeners will need to match those found on Boilers 3 & 4. I do not have access to these parts while boilers 3 & 4 are currently in operation. Please attempt to estimate requirements and bid appropriately. We will confirm prior to starting construction.

Question 7: For demo and installation, a crane will be needed for the elevated work and material placement. What is the access availability and placement location for a crane to perform the SOW? Please advise and provide a site plan for crane placement.

Answer 7: There is space off the North East Corner of the building that is sufficient for crane operation.

Question 8: For demo and installation, a scaffolding system needed to be erected. Are there any special requirements or concerns for use of scaffolding? Please confirm assumption of no special requirements.

Question 8: A scaffolding plan will need to be submitted with the safety plan.

Question 9: Reference drawing M3, Boiler #2 elevation plan. Top of I.D. Fan boiler #2 indicates an expansion joint. Please confirm that the stack above expansion joint is to be left in place for the SOW and the stack above is supported by overheat structures with no change to the mounting to the exist stack.

Answer 9: Concur. Everything above the expansion joint is to be left as is and is supported separate from the ID Fan.

Question 10: Reference drawing M3, Boiler #3 & 4 elevation plan: For the SOW on boiler #2 please confirm the building structure is the same as shown on Boiler 3 & 4 Elevation Demo plan of the same page.

Answer 10: Concur. Structure above and around Boiler 2 is identical to that of Boilers 3&4.

Question 11: Can roof or side wall panels be removed to perform equipment rigging for the

SOW.

Answer 11: Removal of roof or side wall panels is unnecessary and is not permitted. Rigging and access to 4 th floor where ID fans are located can be accomplished by using double doors that open to partial 3 rd floor roof top. See pics 4_3 and 4_5 for doors located next to ID Fan 2.

Question 12: Reference drawing M6, Expansion joints EX-J1 (2 ea), EX-J2 (1 ea). Per manufacture the schedule for design pressure noted at 14 to 14.7 (PSIA) is not available in this model. The recommended pressure is 14" WC. Please confirm this acceptable. See attached for manufacture configuration.

Answer 12: The drawing is correct. Design pressure is 14-14.7PSIA. I noticed in the email attachment the FLEXCOM contact stated 14.7PSIG. I believe this may be the issue.

Question 13: Reference drawing M6, Expansion joints EX-J1 (2 ea), EX-J2 (1 ea). Per manufacture the schedule for frame noted at "Internal - J", is not configured to U-Belt type.

Please advise. See attached for manufacture configuration.

Answer 13: The drawing is correct. The information is directly from the manufacturer.
