Narrative of Events
J une 2011 proved to be the most
productive month of construction
on the COBE project to date. This
was in large part due to consistent
climate conditions typical for the
region. With these weather improvements and a well exe-
cuted strategy, the Contractor experienced zero lost work
days and was able to fully recover the balance of schedule
deficits from earlier in the year. Major augmentation con-
tinued at the Lecture Hall, where skin elements such as sandstone, precast and brick finished
within a week of their baseline schedule. Consummation of EPDM Roofing on this structure has
created a “dried-in” building. Installations of exterior storefront and curtainwall systems are sub-
stantially complete, with the first delivery of glazing scheduled to arrive on-site July 5th. Interior
build out of the Lecture Hall has included the MEP overhead rough-in on both first and second
floor, along with the ceiling construction in the main hall.
S ite development has progressed on schedule, with the
primary focus remaining on Phase II improvements at the
Morrison Lot and Earle Street. Primary and Communication
vaults with their associated conduit bank were extended from
Brady St. to within fifty feet of the main building. Sidewalk
placements along the North side of Brady Garage, followed
this installation, along with new landscape irrigation and curb
line preparation. Earle Street closure and demolition were preceded by the asphalt paving and re
-opening of Brady St. ACHD approval of the Civil Design package resulted in a two week delay of
the Contractors procurement of a ROW Improvements permit. Final approval of these Plans re-
sulted in the Owner’s issuance of a Construction Change Di-
rective, incorporating additional storm drainage and surface
improvements at the intersection of Earle St. and University
Ave. The new United Water main from Capitol Blvd. to
Earle St. was installed with domestic, fire and irrigation ser-
vices extended to the building points of connection. City
fire hydrant abandonments and replacements were com-
pleted during the execution of this work as well.

Narrative of Events
S ignificant enterprise occurred on both the exterior and in-
terior of design area ‘B’, the South wing of the main build-
ing. Exterior framing has finished on all elevations, excluding a
section along the East elevation where future structural tie-in
occurs with the Lecture Hall. Exterior sheathing and fluid air
barrier applications were followed by the start of sandstone,
precast and brick finish elements on the South, East and North
wall elevations. Interior framing, MEP and BAS rough-ins were
completed on all three floors, along with top of wall sheathing
and fire taping . Electrical wire pulls thru these floors areas are complete as well, while wall sheath-
ing, soffit framing, can lighting and Chilled Beam installation has commenced on first floor. Interior
rough-in and preparation for finish are on schedule in building area ‘B’.
B uilding area ‘A’ experienced a dramatic metamorphosis
during the month of June. The structural erection which
completed at the first of the month, was followed by deck
rough-in and concrete placements. The Contractor was able
to prepare and turnover a floor per week, placing first thru
third floor as well as the roof during the 30 days of June.
Spray applied fire proofing has followed each concrete floor
placement, with work substantially completed on first thru
third. Exterior wall framing was started on the North elevation of this building area, and will com-
plete the first week of July. Interior framing on first floor is complete, with MEP overhead and wall
rough-in close behind; These same activities are well underway on second and third floor.
W ith the utility of BIM Coordination Drawings, the Con-
tractor and Owner have experienced zero construction
impact due to MEP system clash. However, major design con-
flicts and base model LOD for the fourth floor were discovered
during the modeling process, requiring substantial Design
Team involvement for resolution. The result of these absorb-
ing efforts was the Issuance of substantial design modifications
exercised thru both RFI Response and CCD issuance. The ad-
vantages of BIM were capitalized by the Owner via the resolu-
tion of these issues, prior to otherwise costly discovery during the course of construction, were such
modeling efforts not employed. BIM CD’s are now complete thru the Penthouse level.

Quality Control
T he month of June saw a return of issues previously undis-
covered, from work completed in earlier months. Most
specifically, embed locations at the top of shear walls, and
anchor bolts within design area ‘A’. These items were discov-
ered once erection activities resumed in area ‘A’ and started
for the 4th floor and Penthouse levels. Additionally, the Con-
tractor’s Spray Applied Fire Proofing Subcontractor, utilized
the LD instead of MD materials required in the exposed ceil-
ing areas of the Second floor Lecture Hall (Innovation Lab).
The material requirements in this area, changed with the issuance of Proposal Request No. 11.1.
Notable structural remediation items, such as the request by the Contractor for approval on rebar
modifications, are the result of “means and methods” adjustments for constructability issues. Other
proactive quality control management measures are exercised, and include both Contractor and
Subcontractor field verification of all precast and sandstone elements, prior to installation.
T he Contractors Quality Control Conformance Report (QCCR) continues to be the primary “data
warehouse” for collecting, sorting, tracking and resolving deficiencies and nonconforming work.
The QCCR is distributed and discussed on weekly basis during weekly Contractor Coordination
Meetings, and during bi-weekly Owner Agency Meetings. All corrected items are catalogued with
supporting photographs, ITL inspection reports and RFI approved correction details and/or direc-
tions. By addressing QC issues immediately and re-visiting open items on a weekly basis, the Con-
tractor is presently achieving an average issue resolution time of 10.8 days.

Design Development
D esign development is anticipated through the duration of a construction project. The impact
of change, however, becomes more substantial as the remaining contract duration diminishes.
The month of June saw a slight reduction from the previous month in the quantity of submitted Re-
quests For Information (RFI). The past three month average, however, reflects a twofold increase
from the previous quarter. This is in large part due to the phase of construction, an acceleration of
site activities, and the movement from preparing submittals to executing work per the Final Bid
Drawings. June also saw a noteworthy increase in the Design issuance of Construction Change Direc-
tives (CCD) and Architects Supplemental Instructions (ASI), both of which were a threefold increase
from the previous month. Pro-
posal Requests from the Owner
increased by twofold during the
month of June as well, all indi-
cating a dramatic project design
evolution
N one of the individual design
revisions alone, represented
a substantial impact to the con-
struction schedule. The multiplici-
ty of change, however, has created a challenge for the Contractor in ensuring all approved design
modifications are accounted for and properly implemented. In most scenarios, a timeline is provided
via either dialogue or submitted COR, for the Owner and Agency to make a decision specific to “Cost
Changes” without impacting schedule or increased investment due to a delayed direction. Addition-
ally, the Contractor is taking necessary steps to proactively inform both Owner and Agency, when
revisions presented via PR should be converted to CCD, based upon work in progress and potential
added cost. These recommendations have generally been tempered with a Contractor explanation
of how a specific Proposal Request would affect immediate construction events and investment re-
quirements, weighed against the desirous propensity of the Owner’s requested change. In many
cases, an initial rough order of magnitude is provided to the Owner, to determine if a revision is truly
desired or needed, so clear direction on how to proceed can be issued. These measures are exer-
cised to assist and ensure the Owner has every opportunity to minimize cost and schedule delay.
There remains some concern, however, with the immediacy of action required for the majority of
design revisions issued. It is the Contractor’s opinion that substantial future investment reduction is
possible, with a more “forward looking” and cognitive consideration of change.

Requests For Information
R equests for Infor-
mation (RFI) tell a
story of the project,
providing snapshots of
where it’s been and
where it’s going. They
can highlight the quality
of construction and de-
sign, while reflecting the
phases and foresight of construction activities. There were 56 RFI’s submitted during the month of June,
with the only substantial change in distribution (2%) occurring between those scored as a 3’s versus 4’s.
Often times, an Owner is most interested in Questions scored as 4’s, as these typically indicate a potential
cost item. Correlations can be made between these items and the subsequent issuance of ASI’s, CCD’s and
PR’s. June saw an almost 50% increase in RFI responses scored 4, from the total of all prior months com-
bined. This is consistent with the previously recognized “spike” in design modifications issued during the
same period. This statistical correlation would appear to indicate that the Contractor is discovering design
anomalies which are becoming the catalyst for further design development.
W ith the grading system employed, other statistical inferences can be made as to how well the Con-
tractor is performing , whether it pertains to a thorough knowledge and understanding of the con-
tract documents (grade 1-2), or a need to correct defective
or non-conforming work (grade 5). This same system can
be used as well, to measure the quality or completeness of
Design (grade 3-4), as these items provide missing infor-
mation which may have an impact on current or “near fu-
ture” schedule activities. Some inquiries, such as those re-
questing clarification/confirmation of design intent or con-
structability, cannot be adequately categorized within the
current system and are subsequently graded as ‘N/A’.
D espite the desire to create a palatable econometric to evaluate the RFI process, their ultimate meas-
ure cannot be obtained through grade assignment, rather it must occur with an understanding of the
potential for added costs of time and money incurred by the Owner, Design Team and/or Contractor, as a
direct result thereof. The statistical data provided herein, does not capture or recognize these affections.
A truer story comes with an understanding of the inception, response, distribution and execution of each
Request for Information.
