Re: Additional Construction Administration Services-
Addition of Gates and Overhead Doors at Tunnel
Dear Ronnie:
The following is a request for additional service charges for continued Construction
Administration services beyond the original contract, on the part of our office and that of our
consultants.
• The Contract (No. 41271), dated 12-14-2010, Section IV, states that "if authorized in
writing by the City, Architect shall furnish or obtain from others-special services
necessary to complete the Projects. These special services are not Included as part of
the Basic Services outlined in Section I-Services of the Architect and Attachment"A".
DESCRIPTION OF CHANGES
On Friday, July 29, 2011, Hahnfeld Hoffer Stanford was asked to provide design services for the
addition of gates for control of livestock and to prevent unauthorized entry into the tunnels. This
request required immediate attention,due to the fact that the gates would require steel imbeds in
the concrete to support the hinges and latches, and because the contractor was in the process
of erecting the forms for pouring the tunnel walls and needed to begin fabrication and placement
of the required imbeds immedlately. A design study was commenced to locate the gates and
imbeds, to coordinate and adjust the locations of fire extinguisher cabinets so that they would
remain accessible when the gates were opened, and to determine the feasibility of cladding the
gates at the entry points to the tunnel to prevent loss of conditioned air from the Richardson
Bass and Moncrief facilities. Drawings were developed and issued for the addition of ten (10)
new gates, one new overhead coiling grille,and one new overhead coiling door.
SCOPE OF WORK
The scope of work involved 1) preparation of plans and details illustrating the proposed gate
designs and layout; 2) preparation of details for steel imbeds and their anchoring in the concrete
tunnel walls to support the gate hinges and latches; 3) consultation with the mechanical
engineer regarding the feasibility of using clad gates or doors at the ends of the tunnel in
conjunction with the tunnel ventilation system; 4) discussions with the Owner regarding layout
and detailing of the gates; 4) modifications of the architectural construction drawings illustrating
the proposed changes, including a) layout of the gates, overhead door, and overhead coiling
grllle on plan sheet A.D1; b) Indication of gates in section on sheets A.D2 and A.D3; c) addition
of gate elevations, sections,details, and schedule on sheet A.D4;5) issuance of the drawings to
the general contractor
*COLLABORATION. *INNOVATION, ,.
COMPENSATION
Total compensation for additional professional services related to the above-noted scope of
work is an hourly fee of$10,510 as detailed in the attached documents. We do not anticipate
any additional reimbursable expenses. Processing of shop drawings and submittals related to
these gates and overhead door and grill are included in our basic construction administration
fee,so no additional compensation beyond the amount stated above is anticipated.
Please contact our office if you have any questions.
Sincerely,
HAHNFELD HOFFER STANFORD

07/29/11 Friday
1. Met with Jack Durham,Chris Harmon,Ronnie Clements,and Tommy Deeds.
a. Reviewed tunnels. Chris Harmon needs to add gates for cattle control. Total of 7 gates.
08/01/11 Monday
1. Met with Tommy Deeds and Adam Stanford regarding priority for his work
a. Start with gates,since they are getting ready to pour footings for the first leg of the
tunnel today,and will need to fabricate the gate hinge plates soon and get placed in the
formwork.
08/02/11 Tuesday
1. Spoke with Les Brown about the tunnel. He said that if we put solid gates at the ends of the
tunnel,the ventilation concept won't work,since the exhaust air idea assumes air is coming
from each of the tunnel legs in roughly equal amounts. He is checking with the mechanical
inspector about Ron Clements'comment.
2. Talked to Adam Stanford about the gates. He has come up with a gate design with horizontal
slats with a gap between for air flow. ]told him to keep the bottom up from the ramp and the
top down from the top of the opening,to allow air flow. We studied the as-built drawings
further and found that the existing ramp has a concrete slab under it with 8 inches of dirt. Need
to be sure that the tunnel floor matches up with the ramp slab.
3. Tommy Deeds about the tunnel gates and briefed him on what I discussed with Adam Stanford.
08/08/11 Monday
1. Reviewed tunnel gate drawing from Adam. Noted that the solid gate,with Y'plate,will weigh
about 1,900 pounds. I think this is too heavy,but called Glenn Calvert at Priefert to ask for
advice. He was not in,so they said that Wayne will call me back. Weight of steel plate is as
follows:
a. Yz"thick=20.4 PSF
b. 7/16"thick=17.85 PSF
c. 3/8"thick=15.3 PSF
d. %"thick=10.2 PSF
e. 3/16"thick=7.65 PSF
2. Discussed gates with Tommy Deeds. Too heavy.
3. Called Glen Calvert with Priefert. He recommended a rough stock gate with 12 gauge plate
welded to the pipe. Said that we need at least 3 or 4 feet at top of gate so someone in the
tunnel can escape a charging bull by climbing over the top. Place sheet metal on side opposite
the climbing side.
4. Researched Priefert site and found the rough stock gate. Saved and marked up for Adam to
correct tomorrow.

08/09/11 Tuesday
I. Reviewed tunnel gates with Tommy Deeds. Called Jack Durham to discuss. Told Jack that we
cannot block off the ends of the tunnel,because that would prevent the ventilation system from
working. Jack explained that they want to prevent people from entering the tunnels. I told him
that Glen Calvert with Priefert recommended that we provide enough space at the top of the
gate for someone to escape in case they are being charged by a bull. He suggested at least 3
feet clear at the top of the gate,with 3'-6" being better. Jack suggested that perhaps a split gate
would work,with the top 3'-6"being separate from the bottom portion. That way,when
someone is in the tunnel,the top portion of the gate will be opened. Regarding weld plates,
Jack suggested that we use"C"channels vertically from bottom to top of the tunnel for weld
plates.
2. Called Mahendra and discussed the channel weld plate idea. He said that he will size as soon as
I give him a plan to look at.
08/11/11 Thursday
1. Worked on tunnel gate markups and revisions. Sent out a draft of plans and details to Tommy
Deeds,Brent MacDonald,Jack Durham,and Chris Harmon for review and comment.
08/12/11 Friday
1. Reviewed tunnel gates with Tommy Deeds.
2. Reviewed tunnel gates over the phone with Brent MacDonald,in response to his email on this.
Marked up changes perthis conversation and briefed Tommy on this. Changed from continuous
channels to 12"x12"imbeds for chain mounting locations.
3. Sent an email to Brent MacDonald telling him to coordinate fire extinguisher cabinet locations
with the gates. Don't want cabinets behind opened gates.
08/29/11 Monday
1. Went to Chris Harmon's office in company car. Met first with James Horner,then with Chris
Harmon on the tunnel gates.
a. Gate GI(Moncrief Building)
i. Only do a half gate—no top escape portion
ii. Add sheet metal cladding to the gate
iii. At end of gate,add a 4 inch post for tying shut without securing with chain. Add
tie off at wall for rope(must be shallow enough to prevent gate from hitting it if
it sags)
iv. Add a manual,chain operated overhead coiling door at the Moncrief side of the
tunnel opening to cover the opening and seal off. They are concerned with
sucking conditioned air from the Moncrief,and are also concerned with noise
from the tunnel impacting the Moncrief arena operations.
v. Went into the Moncrief building with Chris Harmon and measured the tunnel on
that side. it is 13'-4"wide by 12'-0"high clear at the wall that will be removed
to create the link between the Moncrief and the new tunnel.
