Answers per Spencer Associates (AOR):

1. On the Architectural Drawings, the demolition notes and floor plan notes are

repeated on each sheet. On demolition plans, key note 5 is called out to

remove existing drinking fountains on sheets A2.1 and A2.3. For floor plans,

key note 8 is called out on the plan only on sheets A2.5 and A2.7. These

sheet numbers correspond to existing drinking fountains to be replaced in

Building A West on the first and second floors. The drinking fountain model is

being added in this addendum. See item I.B.1. Mechanical drawing M2.1

shows the first floor drinking fountain. The second floor drinking fountain is

not shown on the mechanical drawings. Refer to sheet A2.3 and A2.7 for

location. See attached RFI/response.

2. Drawing A5.1, key note 12 references a urinal screen. The detail reference is

Item No. 2 Guard Rail Infill Panel Clarification

Question per RFI No. 2 from Rodan Builders, Inc. – Per sheet A8.4 it calls for OPUS 30 infill

panels for the guard rails, this is typical throughout. However, in the specifications it calls

for cable railing. There are also no specifications for the OPUS 30 panels. Please advise.

attached RFI/response.

Item No. 3 Data Cabling Clarifications

Questions per RFI No. 3 from Rodan Builders, Inc.:

1. On plan sheet E3.5 sheet note #7 is states to replace existing Cat5 with new

Cat6, however there are no outlets shown for this work. We need to know

how many cables we are supposed to replace in all of these rooms.

2. In addition, on plan sheets E3.1-E3.4 same sheet note #7 states to replace

existing Cat5 with new Cat6, however in all of these rooms, it is only showing

two outlets in the rooms. Are we to figure on just two one cable locations in

all these rooms, or is there more required?

3. For the open triangle data symbol, are we to assume that this is a single Cat6

cable outlet or are more required at each of these outlets?





phone: 650.482.2840

Answers per Spencer Associates (AOR):

1. See attached revised drawing E3.5.

2. There shall be replacement of (2) existing single-jack data outlets and the

associated cabling in each classroom. All other existing cabling and data

on drawings, new Cat. 6 or Cat. 6A shall be provided to new data outlets at

new locations throughout the classrooms, as noted on drawings. (Sheet notes

#13, 14, 15 on E3.3. Other sheets similar). Typical classroom data outlet

wall, (2) on ceiling for Wireless Access Point, (1) at +46” AFF adjacent to

entry door for VoIP telephone system, as shown for each classroom on

drawings E3.1 through E3.4.

3. Per E0.1, the data symbol is a single Cat. 6 cable outlet, except where shown

installed in existing wiremold, as shown on drawings.

Item No. 4 Material Clarification / Installation Coordination
