• We Have noticed that there is no Mobilization item (0975002) on the bid item list. Please advise.

A. The Special Provision entitled “NOTICE TO CONTRACTOR – MEASUREMENT AND PAYMENT “(amended in Addendum #2) specifies how these items are to be paid.

Q. Questions regarding CSI SECTION 088755 – GRAFFITI RESISTANT GLAZING FILMS: • The spec says “all glazing shall get sacrifial 7mil graffiti film” sheet # 149 shows a glass

curtainwall going up 3 stories do you want graffiti film on all of this glass? Inside and outside?

• There is also glass that surrounds the stairwell – do you want graffiti film on this glass… inside only?

• Sheet 153 shows the skywalk …it seems that graffiti film would be well advised on interior but not exterior- please advise if you want on both sides of glass here?

• The spec also says “single layered product, 6mil thick applied to interior glass surfaces, consisting from outboard surface to inboard surface”… does this mean you want film to be applied to the interior side and exterior side of each window therefore doubling the square footage of the scope?

• Will you allow a substitute product made by 3M in a 7mil thickness…same or better performance characteristics?

A. CSI Special Provisions entitled “CSI SECTION 088755 – GRAFFITI RESISTANT GLAZING FILMS” is hereby deleted in this addendum. The CSI special provisions entitled “CSI SECTION 084423 – FIRE-RATED GLAZED STEEL CURTAIN WALL; CSI SECTION 088000 – GLAZING; and CSI SECTION 088117 – FIRE-RATED GLASS” are hereby revised in this Addendum.

Q. To construct the drilled shafts between catenaries 1016 and 1017 on the out bound side of the station the contractor will have to access private property. Has the CT DOT acquired temporary rights of way access for the construction of the drilled shafts between catenaries 1017 and 1016 on the out bound side of the station?

A. The Special Provision entitled “Notice to Contractor – Rights of Way Restrictions” is hereby revised in this Addendum. An Easement to Construct and Maintain Platform and Canopy has been acquired for the South Platform.

Q. In the initial specification item number 0204210A, Handling of Contaminated Groundwater, was to be accomplished by an on-site treatment system under an estimated cost item. Addendum #3 changed the handling procedure to on-site storage with transportation off site for disposal under a Lump Sum payment. Since the volume of water to be transported is an unknown quantity, on what basis is the bidder to establish a Lump Sum price?

A. Boring logs are provided on the plan sheets. The geotechnical reports and environmental reports are available for viewing by contacting Philip J. Melchionne at [email protected]. The contractors’ means and methods, will determine volumes of water that will need to be treated. Therefore, the Special Provision entitled “ITEM #0204213A – HANDLING CONTAMINATED GROUNDWATER” has a Lump Sum pay item.

Q. Item No. 1203109 - Side Mounted Sign Foundation has a bid quantity of 85 ea. The plans and

specifications indicate only (2) side mounted signs (#095-156-055A & #095-156-115A) requiring only 4 ea. sign foundations. Where are other 81 ea. foundations?

A. The quantity for the item entitled “Item No. 1203109 – Side Mounted Sign Foundation” is hereby revised in this addendum.

The Detailed Estimate Sheets do not reflect these changes. The Bid Proposal Form has been revised to reflect these changes. There will be no change in the number of calendar days due to this Addendum. The foregoing is hereby made a part of the contract.

C. Protect glass edges from damage during handling and installation. Remove damaged glass from Project site and legally dispose of off Project site. Damaged glass is glass with edge damage or other imperfections that, when installed, could weaken glass and impair performance and appearance.

D. Apply primers to joint surfaces where required for adhesion of sealants, as determined by preconstruction sealant-substrate testing.

E. Install setting blocks in sill rabbets, sized and located to comply with referenced glazing publications, unless otherwise required by glass manufacturer. Set blocks in thin course of compatible sealant suitable for heel bead.

F. Do not exceed edge pressures stipulated by glass manufacturers for installing glass lites.

G. Provide spacers for glass lites where length plus width is larger than 50 inches as follows:

1. Locate spacers directly opposite each other on both inside and outside faces of glass. Install correct size and spacing to preserve required face clearances, unless gaskets and glazing tapes are used that have

Page 35: JULY 29, 2010 ADDENDUM NO. 6

GLAZING 088000-18

demonstrated ability to maintain required face clearances and to comply with system performance requirements.

2. Provide 1/8-inch minimum bite of spacers on glass and use thickness equal to sealant width. With glazing tape, use thickness slightly less than final compressed thickness of tape.

H. Provide edge blocking where indicated or needed to prevent glass lites from moving sideways in glazing channel, as recommended in writing by glass manufacturer and according to requirements in referenced glazing publications.

I. Set glass lites in each series with uniform pattern, draw, bow, and similar characteristics.

J. Where wedge-shaped gaskets are driven into one side of channel to pressurize sealant or gasket on opposite side, provide adequate anchorage so gasket cannot walk out when installation is subjected to movement.

K. Square cut wedge-shaped gaskets at corners and install gaskets in a manner recommended by gasket manufacturer to prevent corners from pulling away; seal corner joints and butt joints with sealant recommended by gasket manufacturer.

3.4 GASKET GLAZING (DRY)

A. Fabricate compression gaskets in lengths recommended by gasket manufacturer to fit openings exactly, with allowance for stretch during installation.

B. Insert soft compression gasket between glass and frame or fixed stop so it is securely in place with joints miter cut and bonded together at corners.

C. Center glass lites in openings on setting blocks and press firmly against soft compression gasket by inserting dense compression gaskets formed and installed to lock in place against faces of removable stops. Start gasket applications at corners and work toward centers of openings. Compress gaskets to produce a weathertight seal without developing bending stresses in glass. Seal gasket joints with sealant recommended by gasket manufacturer.

D. Install gaskets so they protrude past face of glazing stops.

3.5 SEALANT GLAZING (WET)

A. Install continuous spacers, or spacers combined with cylindrical sealant backing, between glass lites and glazing stops to maintain glass face clearances and to

Project No. 106-116 34 ADDENDUM NO. 6

Page 36: JULY 29, 2010 ADDENDUM NO. 6

GLAZING 088000-19

prevent sealant from extruding into glass channel and blocking weep systems until sealants cure. Secure spacers or spacers and backings in place and in position to control depth of installed sealant relative to edge clearance for optimum sealant performance.

B. Force sealants into glazing channels to eliminate voids and to ensure complete wetting or bond of sealant to glass and channel surfaces.

C. Tool exposed surfaces of sealants to provide a substantial wash away from glass.

3.6 LOCK-STRIP GASKET GLAZING

A. Comply with ASTM C 716 and gasket manufacturer's written instructions. Provide supplementary wet seal and weep system, unless otherwise indicated.

3.7 CLEANING AND PROTECTION

A. Protect exterior glass from damage immediately after installation by attaching crossed streamers to framing held away from glass. Do not apply markers to glass surface. Remove nonpermanent labels, and clean surfaces.

B. Protect glass from contact with contaminating substances resulting from construction operations, including weld splatter. If, despite such protection, contaminating substances do come into contact with glass, remove substances immediately as recommended by glass manufacturer.

C. Examine glass surfaces adjacent to or below exterior concrete and other masonry surfaces at frequent intervals during construction, but not less than once a month, for buildup of dirt, scum, alkaline deposits, or stains; remove as recommended in writing by glass manufacturer.

D. Remove and replace glass that is broken, chipped, cracked, or abraded or that is damaged from natural causes, accidents, and vandalism, during construction period.

E. Wash glass on both exposed surfaces in each area of Project not more than four days before date scheduled for inspections that establish date of Date of issuance of the certificate of compliance. Wash glass as recommended in writing by glass manufacturer.
