49. Question: Reference Documents: A-601 – Door Schedule

1) Please confirm the blast rating required per remarks key#2 on the door schedule on A-601.

2) Does the blast rating apply to the door frame?

Please confirm storefront door A102A is to have a blast rating.

49. Answer: 1. Blast rating requirement is confirmed and is based on the actual standoff distance.

2. Yes, door, frame, and all glazing components are required to have a blast rating.

50. Question: On E-601 (one-line diagram) shows site transformer “T12” size as a 1500KVA and on ES101 NOTE 1 has it is sized at 1000KVA, please clarify which transformer to provide.

50. Answer: Provide 1500kVA transformer per sheet E-601.

51. Question: On ES101 CATV direct buried conduit is shown from new CATV handhole into building, is this the total length of direct buried CATV conduit?

51. Answer: The total direct buried PVC CATV conduit length includes what is shown on ES101 and continues on T-101 into Primary Comm Room 118.

52. Question: On ES101 NOTE 7 says conduit is to be (1)-4” PVC direct buried conduits. On T-101 it is shown as (2)-4” PVC direct buried conduits. Please clarify.

52. Answer: Provide (2)-4” PVC conduit for CATV cabling as shown on T-101 and stub ups shown on T-401.

53. Question: The Sliding Hangar Tail Door on sheet A-312/detail A1 is shown to be 23'-6" tall.

However, paragraph 2.1.2 of section 08 34 16.10 calls for a height of 11' for the Jamb Guide Canopy Tail Door. The height of 11' as given in paragraph 2.1.2 appears to be a misprint. Please clarify that the height of the Tail Door is to be 23'-6" as per sheet A-312 rather than the apparent misprinted height of 11'.

53. Answer: Specification 08 34 16.10, paragraph 2.1.2, Jamb Canopy door height is 23’-6” high per sheet A-312/detail A1, not 11’ as stated in error in paragraph 2.1.2. Minimum clear opening when jamb door is shall be 60’, but the detail and 23’-6” dimension should allow for more clearance

54. Question: There is no specification regarding Fire Extinguishers. Please confirm that fire extinguishers will not be required.

54. Answer: Fire Extinguishers are not required.

55. Question: Specification 09 90 00, Section 1.3.2 requires the coating applicator to be SSPC QP 1 certified. This certification is typically held by bridge, industrial, marine, and tank coating companies.

There are very few commercial painters that have this certification and the process of obtaining the certification takes a considerable amount of time. If a company attempted to obtain the certification after the bid, they likely would not receive it before their scope of work would need to begin. This limits the pool of subcontractors considerably and results in increased costs. Please advise if the SSPC QP-1 requirement can be waived for this project.

55. Answer: The requirement for SSPC QP 1 is not required

56. Question: In Section 12 21 00 WINDOW BLINDS, Par. 2.1.1 calls not only for "horizontal blinds with 1 inch slats" but also to "Provide tapes for 2 inch slats with longitudinal reinforced…". These two conditions contradict, as they denote two different slat widths. Please indicate which one of these horizontal blind slat widths, 1 inch or 2 inch, is intended.

56. Answer: 1-inch blinds are intended.

57. Question: The RFP does not state anything in regards to fire extinguishers. Please confirm that fire extinguishers are not required in the proposal.

57. Answer: Fire extinguishers are not required.

58. Question: Para. 1.4 Performance states " exterior doors in portions of the building that are designated as inhabited shall provide a Low level of protection for the peak pressure and positive phase impulse that correspond to Explosive Weight II as specified in UFC 4-010-02 (FOUO) at the actual standoff distance (as indicated in civil drawings) to parking, roadways, or trash containers." However, there is no standoff distance indicated anywhere on the civil drawings. Please provide the required standoff distance that will allow us to properly quote the job with adequate protection for doors, hardware, and glazing.

58. Answer: Drwg CS102 indicates a distance of 70ft from the Bldg to the edge of the parking lot and 57ft from the Vehicle access Gate to the edge of the building.

59. Question: Paragraph 2.3.7 indicates for doors and equipment to be approved for use in Hazardous Locations. The Hazardous Plan E 011 talks about only needing to be Explosion Proof 18" above the floor.

The door operators & controls are above 18". It is our belief the operators don't have to be Explosion Proof. Please clarify. Also you can get Explosion Proof operators & you can get Fire Door operators but you cannot get Explosion Proof fire door operators. Please clarify whether Explosion Proof or Fire Rated Operators are required.

59 Answer: It is of assumption this question refers to specification section 08 34 19.10 20 Rolling Service and Fire Doors. Door operators or Fire Door operators outside of the hazardous regions as defined on sheet E-011 do not require explosion proof enclosures.

60. Question: Paragraph 1.2.1 names "Columns 10-A through 10-K" structural steel supporting fire rated walls along "grid M" as locations for intumescent fireproofing. Per the Column Schedule on S-400 as well as plan sheets S-100 through S107, locations using these reference points do not appear to be a part of this project. Please advise if these specific references are in error and if so, provide corrected references for this section of the specification.

60. Answer: Paragraph 1.2.1 of spec 07 81 01 is in error. See response to question 26 and 42

61. Question: Please confirm, given the Answer to Question 26, that the structural steel and steel decking found in Paint booth 133 and Electrical 138 are the only locations to receive Intumescent Paint Fireproofing.

61. Answer: Confirmed, only Paint Booth 133 and Electrical Room 138 to have Intumescent Paint fireproofing. See response to question 26 and 42

62. Question: On sheet CU506 are details for the containment tank. Please provide a specification for the tank, diversion plug valve and motor actuator. Provide details for control panel in the hangar, and interface with HEF system.

62. Answer: Tank is specified on the drawing with the notes. Control panel for the diversion valve is indicated in the hangar on the Mech Drwgs M105D Keyed Note 4, Fire Alarm Riser FA601 Keyed Note 19, Fire Alarm Matrix FA602C (Fire Alarm Control Unit (FACU) Functional Matrix), and Electrical plan E-105. Diversion Valve is specified in Spec Section 33 30 00 para. 2.4.

63. Question: Hoist and Trolley speeds are not specified in section 41 22 23.19. Confirm the following are acceptable or provide additional information.

5-ton Pantented Track Bridge Crane:

1) Bridge Crane speed 0-100 fpm using variable frequency drive.

2) Trolley speed 0-50 fpm using variable frequency drive.

½-Ton Monorail System

3) Typically these systems utilize a top hook mounted chain hoist with the specified track.

4) Hoist speed to be 15 fpm single speed.

63. Answer: 1, 2, 3, and 4: Acceptable

64. Question: ES101 Electrical Site Plans. Keyed Notes 1&2 on the attached document says to coordinate the transformer and the switch with the local utility.

Do we need to carry these items in our estimate or will Alcoa Utility provide these?

Also Keyed Note #3 states to provide 3-133% ERP 2/0 aluminum from the transformer to the switches.

Is this something we need to carry or will Alcoa Utilities supply the cable and the terminations as well?

Are there any aid to construct monies we need to know?

64. Answer: The City of Alcoa will install the medium voltage cable, pad mounted switches and pad mounted transformers. The city previously provided the A/E a cost of $125,286 as their bid cost for this.

Each contractor shall coordinate with City of Alcoa electrical on any updated estimate in their bid for the work to be performed by the City of Alcoa.
