Delete SP-13 and replace with revised SP-13:
“These Special Provisions are intended to supplement and not
replace the provisions of GP 70-08.
The installation of the canopy replacement steel and fabric and the
addition of a glass enclosure wall will require the use of
safety/visual screening barriers around the work areas at the 5th
level and at the potential shoring locations on other floors of the
garage to keep pedestrians and vehicles from entering into areas
that might present unsafe conditions. Additionally, barriers will be
erected at the first through fourth floors to keep the public from
entering the atrium area to provide safety relief from the
construction activities above. A vehicle movement tunnel, indicated
by a designation of a GT-2 type barrier, will also be provided by the
General Trades Contractor as indicated on the documents. The
vehicle tunnel shall have a minimum height clearance of eight feet
six inches (8’6”) and a minimum horizontal clearance of fifteen feet
(15’) for the length of the vehicular tunnel. Scaffolding and
overhead protection shall be constructed to meet applicable safety
regulations and standards. The sides of the vehicle tunnel shall a
safety barrier to keep pedestrian traffic for accessing the atrium
area.
The General Trades Contractor will be responsible to erect, move
and dismantle these safety/visual screening barriers within the
garage structure as indicated on the bidding plans. All construction
activities must be coordinated with the General Trades contractor
to provide timely notification and coordination of the schedule
needs regarding the safety/visual screening barrier erection,
relocation and removal.
The safety/visual barriers, indicated as a GT-1 type Barrier on the
documents, shall be a minimum of six feet in height, provide a
continuous safety barrier to pedestrian access, shall include
indicated access points for egress to existing elevators and
stairwells and shall be installed to withstand normal wind
conditions that can be expected to occur in the construction areas.
The barriers may not be attached directly to the concrete
slabs/decks. Temporary weighting methods are to be used to keep
the barriers in place and upright. The barriers may be constructed
using either a chain link fence structure with approved mesh
screening and appropriate access points or a solid material barrier,
e.g. Plywood sheets. If a solid barrier is constructed, it will be
required to be painted and have screening material with Airport
Page 4 of 10
graphics mounted on exterior or have the Airport graphics be
added through the use of paint and stencils.
This Contractor will also provide weather protection over the
existing escalators and moving sidewalks in the garage as part of
this Special Provision. Protection to consist of plastic sheets
installed over a temporary wooden frame to minimize the effects of
rain and dust to the equipment. The framing is to be installed such
that the escalators and moving sidewalks are not accessible to
pedestrian traffic, but can be run on an intermittent basis to allow
operating parts to be oiled and maintained
All other safety/visual screening barriers that are required
exclusively for the Work of the General Trades Contractor are to be
provided by the General Trades Contractor. Safety/screening
perimeters around material staging and fabrication areas shall be
comprised of 6 foot high chain link fencing with mesh screening
attached as indicated upon the plans. Mesh screening is to be
provided similar to a Series 111 printed screening material as
shown on FenceScreen.com. See attached sketch “SK#05” for photo
of typical level of custom graphics that may be required on the
mesh screening. Also see attached sketch “SK#04” regarding mesh
screening required on temporary construction safety fencing to be
installed during canopy fabric replacement. See Sketches “SK#16”
through “SK#24” for locations of safety/visual barriers, information
is provided for reference only.
The General Trades Contractor shall include in their bid the cost to
provide 500 orange movable pylons, Looper-Tube Delineator Post
with Reflector Bands, and 4,000 feet of plastic chain material to
connect the orange pylons together to form traffic control barriers
and directional delineation for temporary traffic patterns in the
garage during construction. The General Trades Contractor is also
to include an allowance of 200 labor hours to install the pylon and
chain barriers in the garage and to relocate when directed. Location
of the temporary traffic lanes shall be determined by the Airport

ramp operations are not impacted and the requirement of a minimum of
4 stair towers and 2 elevators are available for public use is maintained.
Response – Yes, see SP-16 and SP-17 for additional information.
10.
Question – Can the cost and responsibility for providing the crane pads,
temporary access roads and the landscape allowance by transferred to
the General Trades scope of work?
Response – Since the extent of the crane pads and temporary access
roads may vary by contractor, it would not be feasible to have the General
Trades Contractor include this scope within their bid. However, the
successful Canopy Erection contractor should be able to negotiate the
providing of this work with the successful General Trades Contractor or
some other contractor prior to the work being required on site.
11.

Page 9 of 10
19.
Question – In specification section 130150 1.14B-1 the manufacturer’s
product warranty for the specified fabric is to be 20 years from the date
of substantial completion. It is our understanding that the four
manufacturers identified in section 2.2A of the same spec only offer
maximum 10 year warranties and some of them are pro-rated. There are
coated fabrics with much greater strength that provide 20 year
warranties. Would the airport entertain such alternate options?
Response – Warranty has been modified from 20 years to 10 years. See
item No.1.A.2 in this Addendum No.2.
20.
Question – Can a time extension be issued to allow more time to study
shoring plan and to contact potential XBE bidders”
Response – Per Indiana public bidding regulations, bids are to be received
within six weeks of bid request. Therefore, the bid date can only be
extended to January 4th, 2016 at 11:00 am. That extension will be noted
in the addenda.
21.
Question – With the indicated anticipated contract award date of January
15, 2016, the contract period of 220 days does not appear sufficient to
complete the Work. Can it be increased?
Response – There seems to be some confusion of the project start up
dates and when the NTP is anticipated to be issued on this Contract. See
anticipated schedule of activities that will be in effect for this contract
(actual dates may vary slightly to reflect actual job conditions):
Board Approval of ContractJanuary 15, 2016
