Work in Progress: drywall taping & finishing, Steel erection, window caulking
Metal stud installation @ first floor, plumbing rough-in, pouring concrete
Discussion Items/Issues:
We had a discussion on the ethylene glycol for the chiller system. HPE has noted that this is not the correct
application for this. The owner needs to review this situation and provide the design and construction team
on a final decision on the use of ethylene glycol.
Installation has begun on the exposed atrium steel columns. The steel appears to be relatively smooth but
the paint on some of the columns has some runs in it. Nunn will monitor this situation and some sanding
and primer touch up will be required.
The steel installation continues to be quite slow. If the weather cooperates, additional time will be put in to
try to catch up some of the lost time.
Observations
Concrete was being poured in room 119. The raised flooring area in room 121 was being formed for
pouring also.
Steel installation is progressing at the infill area from column lines F to H. Most of the basic structure has
been erected for the east addition. Most of the edge steel and plate supports for the masonry supports
have now been installed. Several of the large round tube columns in the atrium have been erected.
Because of limited site space, small amounts of steel are delivered and then erected before more steel can
be delivered.
Access to the site is being restricted due to other construction on the campus. Mountain Lion road is
blocked regularly for work on the Engineering building
Metal wall studs are being continuing to be installed on the first floor. Drywall installation has begun at the
west end of the floor. Most of the metal studs are now in place on the first floor.

Metal stud installation @ first floor, plumbing rough-in, Tile installation
Discussion Items/Issues:
There was a discussion on the chiller and evap pre-cooler. It is not scheduled for a mid April delivery with a
possibility of moving that up a little. Nunn will evaluate the schedule to see how this will impact the overall
schedule.
The fix for the glass installation has been completed so that all glass can be installed without damaging the
surrounding walls.
There have been numerous problems w/ the steel fabrication and installation. Nunn is working w/ Pikes
Peak to try to minimize these problems. The problems are causing the installation to proceed very slowly
because of the field fixes that are being required.
UCCS noted that they need to have key locks on the access panels in the toilet rooms where they are
accessible to the public. There are just screwdriver locks on the panels currently. Nunn will investigate this
and get these changed.
Observations
The floor and wall tile are nearly complete in the second floor toilets.
Installation of the light fixtures and diffusers has begun on the third floor.
Steel installation is progressing at the infill area from column lines F to H. Most of the basic structure has
been erected for the east addition. Most of the miscellaneous edge angles, etc. has not been installed yet
so the decking can not be installed yet. The supporting channels for the masonry are not yet installed
either at this area.
Edge angles for the ceiling are being installed on the second floor in interior rooms where painting has
been done.
Metal wall studs are being continuing to be installed on the first floor. Drywall is scheduled to start next
week on the first floor.

Discussion Items/Issues:
There was a discussion on the chiller and evap pre-cooler. Dwayne will be reviewing the need for an area
drain in the chiller area.
I will see that I get a site observation report for Rimrock’s latest visit to the site to document their findings
and note the changes that are being worked out in the field.
Observations
The FSK paper installation is continuing on the second floor.
Ceiling Tee’s are being installed on the third floor.
The drywall is being installed at all the exterior walls where the window frames have been installed. The
first glass was installed on the second floor at the east end.
Most of the remaining floor slab within the existing building was being poured today.
The steel erector was on site and installation of the steel has begun at the east end of the south addition.

Reinforcing placement @ first floor, Plumbing installation in Mech. Room
Discussion Items/Issues:
The contractor is preparing the first floor areas for the new first floor concrete slab. This includes the area
of the new coffee shop. Currently we have only included the rough-in for two sinks on the north wall of the
coffee shop. Unless UCCS give other direction for this area the contractor intends to pour the slab in this
area next week.
I have just received the submittal for the pre evap cooler for the chiller. The contractor needs information
on the utilities for this cooler ASAP, as the drains in the mechanical room are being backfilled and the work
in the outdoor chiller area is proceeding.
UCCS is investigating the drainage within the chiller area to determine if they want an area drain in this
area.
Observations
The FSK paper is being installed over exposed insulation above the ceiling line. The contractor is to
provide documentation that this paper meets the flame spread requirements of the FSK-25 which was
approved.
Painting is ongoing on the second and third floors. The P-2 paint sample was not approved as submitted
and needs a new draw-down to be approved. The P-1 and P-3 samples were approved as submitted.
Ceiling wall angle installation has begun on the third floors where the painting has been done. Painting
of the door frames has not yet begun.
A significant amount of the first floor slab within the existing building has been poured. Work continues on
the raised floor sections in the tiered classrooms and also in the lecture hall.
The steel erector was on site installing some steel plates required for the atrium steel which is scheduled to
arrive on site 1/29/07.
The brick has been installed on the second floor at the north side at the west end.

Work in Progress: drywall taping & finishing, Painting
Reinforcing placement @ first floor, Plumbing installation in Mech. Room
Discussion Items/Issues:
The second floor toilets are 2” narrower than was shown on the drawings due to the location of the existing
wall below which kept the drain lines to be located closer to the existing wall. We discussed what needed
to be done with the toilet partitions to keep the proper clearances for ADA requirements. I have given the
contractor information on what is acceptable and a new shop drawing will be submitted to confirm the
dimensions.
We discussed RFI #74 regarding the location of the roof drain piping in the southwest corner of the
building. HPE was not using the latest coordination drawings when installing the piping. After reviewing
the current drawings a route was found which would not require a core drill thru the existing columns.
We have not yet received the final information on the evaporative pre-cooler on the chiller. This
information is required to finalize the chiller area and any drainage that may be required.
Observations
All of the aluminum frames on the east and west along w/ the frames into the atrium are in place. Glass is
scheduled to arrive in about two weeks.
Most of the first floor has now been graded to the correct elevations and the reinforcing for the slab is
being placed. The first pour is scheduled for tomorrow and a second pour is scheduled for next week.
Steel for the atrium is now scheduled to arrive on site 1/29/07.
Painting is continuing on the third floor and some priming has started on the second floor.
The electrical rough-in under the first floor slab is nearly complete.
The window on the second floor at the north side at the west end was enclosed so the brick under the
window could be installed.

Reinforcing placement @ first floor
Discussion Items/Issues:
El Paso Glass submitted an RFI for the type H window on the north side of the building. Carl and I
discussed the RFI and I responded to the RFI so it could be returned to El Paso. After the chiller discussion
at the meeting Carl & I reviewed the existing space for the chiller. There is a short wall protruding from the
existing wall which will impact the location of the chiller. I called John Brunner and I will send a plan
sketch to him for his review to determine if this wall can be removed which should allow us to locate the
new chiller on the existing pad. It appears that when the slab is replaced where it has been removed for
the electrical installation it can be sloped to allow drainage out of the chiller area without a drain. The
existing drain in the area is currently not functioning and it is unknown what the problem is. The York
chiller supplier will be getting additional info on the chiller so that it can be ordered ASAP. Additional info
is also needed on the evaporative pre-cooler so engineering can proceed for the electrical connections and
the water supply and drain.
Observations
Mechanical & Electrical rough-in on the first floor is proceeding. Reinforcing for the first floor slab is being
installed and the contractor is preparing for the first pour of the first floor late next week.
Most of the underground electrical is in place. The KI installer will be checking the rough-ins to confirm
they are ok and will match what is needed for KI at the tiered classrooms.
Taping and finishing of the drywall walls is on-going on the second floor.
Most of the walls on the western 2/3’s of the third floor have been primed. The painter has been given the
typical colors for the walls, corridors and frames so final painting can begin.
Window frames have been installed on the third floor on the east end of the building and the third floor on
the west end was being installed.

Work in Progress: drywall taping & finishing, Painting
Compacting grade @ first floor
Discussion Items/Issues:
A coordination meeting was held w/ the electrical subcontractor to discuss the rough-in electrical at the
tiered classrooms on the first floor. The KI shop drawings for the fixed tables in the tiered classrooms
shows a single location for power and a single location for data to enter the tables. It was decided that a
second location for data should be added to provide for future expansion capabilities. Dwayne will meet
w/ the KI rep to coordinate the additional data location.
Observations
Compaction of the subgrade inside the building is about complete. Electrical rough-in is inprogress in the
area of the tiered classrooms. Work is continuing on the plumbing rough-ins on the first floor.
Work on the exterior at the atrium is continuing but is still being delayed due to weather. The steel columns
for the atrium are scheduled to arrive in a couple of weeks.
Taping and finishing of the drywall walls is on-going on the second floor.
Almost all walls on the third floor have been primed. A final color decision is needed so that painting can
continue on the third floor.

Work in Progress: Duct installation, drywall installation, drywall taping & finishing
Compacting grade @ first floor
Discussion Items/Issues:
Carl and I discussed the need for the locations for the floor boxes on the first floor and the need to resolve
the drain lines in the mechanical room. Both of these items impact the schedule for pouring the first floor.
I told him the floor box locations would be available and given to Nunn today. Additional discussions will
need to take place before a decision can be made on the floor drains.
Some water had entered the building thru the abandoned louvers on the south sides of the stair towers.
These louvers were blanked off on the interior. Nunn will investigate some way to cover them on the
exterior to ensure that water cannot enter thru the louver.
There are still a couple of locations where the access to the VAV boxes is not acceptable. The one in Hall
300G is directly over a door and it was not suppose to have a wall or drywall at the unit but the drywall
sub installed the drywall so the VAV was not acceptable. It appears that if the drywall and studs are
removed above the ceiling line the unit will be accessible. Nunn was to see that this is completed.
There is a VAV unit in Hall 300H which has a fire sprinkler line in the way of the access panel. This line
can have several elbows added so the sprinkler line is moved south at the VAV access panel and the
reconnected once the line is past the VAV box, probably about a 3’ length can be moved about a foot to
the south. Nunn is to instruct the Fire Sprinkler Sub to move this pipe.
There is a VAV box in Room 356 which serves 356A which has a roof drain adjacent making the service to
the VAV box unacceptable. The only option that appears acceptable to allow service to the VAV is to move
the VAV and supply line three double tee bays to the south which will put it in the southern most opening
within room 356A. The supply duct then can be moved to connect to the main supply in Corridor 300B-4.
Nunn shall work w/ HPE to provide acceptable access to this VAV box or move it to a location where it is
acceptable.
Observations
Compaction of the subgrade inside the building is in nearly complete. The areas of the tiered classrooms
is taking form and only the underground electrical and plumbing needs to be completed so that the first
floor slab can be poured.
Work on the exterior at the atrium has been delayed due to weather and the large snow storm right before
Christmas. More snow was falling today and a large storm is predicted for tomorrow.
Room 355A is completed and has been painted. The quality of the paint installation appears to be
acceptable. The door frame was recently caulked but has not yet been painted.

Compacting grade @ atrium and first floor
Discussion Items/Issues:
Carl and I looked at the boiler flue as it goes thru the second floor mechanical room and then up thru to
the third floor. CRA was also on the site and will investigate the requirements for the shaft around the flue
as it relates to the combustion air for the boiler below. CRA will provide an answer to question via the RFI.
Carl had a question regarding the steel in the new first floor slab on grade. The drawings indicate a
sawcut control joint equal to ¼ the slab thickness. In this case that is 1”. The slab detail also indicates a
1” clearance from the top of slab to the top of reinforcing. Carl proposed to increase the 1” clear to be 1
½” clear. I talked w/ John Bruner w/ M/M and he is ok w/ the 1 ½” clear.
Carl and I discussed the routing of the lightning protection wiring routing on the south side of the building
at the curtain wall. There appears to be a route thru the large round columns at the two required locations
in the atrium if the conduit is installed in the columns in the shop. Carl will coordinate w/ the steel sub and
the lightning protection sub to get the wiring concealed in the columns. The two locations were noted on
the lightning protection shop drawings.
Nun noted that some additional clean outs were shown on a civil sheet that was signed by CSU which have
not been installed. I talked w/ Cheryl Bean and CSU does require these clean outs per their latest
regulations. The cleanouts are in a pipe which is existing and we have not changed between the new
manhole south of the Dwire to an existing manhole south of Main Hall. It appears that 2 clean outs will be
needed to meet the requirements. Nunn will provide pricing for these cleanouts before a decision on
when this work will be completed.
Window frame installation on the east and west walls is scheduled to start next week.
Observations
Compaction of the subgrade inside the building is in process. CTL is testing the work and the
recommendations for proper moisture content is making the compaction difficult. CTL is performing test as
required to make sure the proper compaction is being attained.
The drywall on walls is complete in all the possible areas on the third floor. Taping and finishing is
ongoing on the third floor. Room 355A is completed and Nunn has requested using this as a test room for
painting to be completed by the owner. Drywall installation is ongoing on the second floor.
Mechanical and electrical subs are working in the mechanical and electrical rooms on the first floor and
the mechanical room on the second floor.

Work in Progress: Duct installation, drywall installation,
Compacting grade @ atrium
Discussion Items/Issues:
There was an additional pipe running thru the chase for the boiler flue on the third floor which had
enlarged the shaft. The installers had moved the wall out to enclose the piping and it took significant
space out of the room. This was noted yesterday by the owner and the installers were in the process of
boxing out around the piping above the 9’ line and then making the shaft as small as possible down to the
floor. It is now as we have it shown on the drawings.
The drywall installers had left an area of wall out above the doors to the stairs at the third floor for no
known reason. Cody would talk w/ them and have this area filled in to match the adjacent wall.
The marking for the floor box was covered w/ drywall. I informed Cody that if the mark was basically in
the center of the room that it was ok to cut the hole and if it needed to move 6”-8” to miss the stem of the
double tee below that was also ok.
Observations
Mechanical and electrical rough-ins are basically complete on all the existing areas on the second and
third floors. Work on the mechanical above ceiling rough-ins is proceeding on the first floor. Final
inspections were just made on the underground plumbing on the first floor so backfilling and recompaction
inside the building can begin. Work on the compaction of the grade on the exterior is
continuing as weather permits.
The drywall on walls is nearly complete on the third floor in all areas where the studs are complete.
Drywall installation has begun at the east end of the second floor.
The building is be heated w/ temporary heaters during the day w/ one of the heaters on the first floor
running 24 hours.
The stair between first and second floor at the west tower has been poured.
Most of the rough-in plumbing has been installed in the toilets at the second and third floors.

Work in Progress: Duct installation, electrical rough-in, work on foundation walls for atrium, installing
Blocking in walls, underground plumbing
Discussion Items/Issues:
Carl and I discussed the need to get the information on the lightning protection so that the leads to the
grounds can be located inside the building within walls or in hidden locations.
The emergency generator location has been identified so that work can continue in the chiller enclosure.
The concrete slab has to change to accommodate the generator and electrical can be installed for the
generator and the chiller. The chiller selection and cut sheet information is supposed to be available
shortly after next Wednesday.
Observations
Mechanical and electrical rough-ins are continuing on the second and third floors w/ some work started on
the first floor. Work has started on the underground plumbing at the first floor.
The forms are being stripped on the atrium grade beams. All the concrete on the piers and grade beams
has been poured.
The building has been temporarily enclosed at all levels so that the installation of drywall can begin next
week on the third floor.
Blocking has been installed at all locations of casework, shelving, markerboards and LCD monitors on the
third floor.

Work in Progress: Duct installation, electrical rough-in, work on foundation walls for atrium, installing
Blocking in walls
Discussion Items/Issues:
We discussed the jambs at the new door 200E-A exit from the west stair. The door will be installed in the
wall just north of the north wall so there is a brick jamb to support a lintel above. The new wall will tuck in
behind the new window in the north adjacent wall.
There are some issues with the mechanical openings in the existing concrete wall on the first floor at
column line 7. John Brunner was at the jobsite on Tuesday and will issue a field report w/ his comments
on these openings. It appears that at least one of the ducts will need to be re-sized to fit a maximum
opening width that can be obtained in the existing shear wall.
There was an opening cut thru the roof for an exhaust duct near column line D.9 and 3. This opening was
changed in IB#18 so the duct was to continue straight up thru the roof w/ no offset. This will need to be
corrected as it was a code issue.
Observations
Mechanical and electrical rough-ins are continuing on the second and third floors w/ some of the fire
sprinkler piping being installed on the first floor. Some mechanical rough-ins were also being worked on
in the first floor. Work as not yet started on the underground plumbing at the first floor.
Work on the atrium grade beams is continuing from east to west along the south side of the atrium.
The repairs on the roofing are nearly complete so the building can be dried in so drywall work can begin.
It is anticipated that drywall work will begin in less than two weeks
11-02-06 CONSTRUCTION FIELD REPORT
Estimated % of Completion: 18%
Work in Progress: Duct installation, electrical rough-in, work on foundation walls for atrium
Discussion Items/Issues:
We discussed RFI #53 regarding existing roof drain piping on the second and first floors.
New openings were marked on the existing concrete wall on the first floor into the mechanical room.
These openings need to miss the bearing points of the steel beams supporting the floor for the second floor
mechanical room. John Brunner is scheduled to visit the site on Friday or Monday and needs to review the
proposed cuts. It may be necessary to change some of the duct sizes to reduce the width of some of the
openings.
Observations
Mechanical and electrical rough-ins are continuing on the second and third floors w/ some of the fire
sprinkler piping being installed on the first floor.
Because of the snow, work has been slowed on the atrium foundation. Some forming work is proceeding
on these foundations.
The contractor has installed temporary enclosures all of the exterior openings. The building is not being
heated yet as there are still some openings in the roof that need to be closed.

Discussion Items/Issues:
We discussed RFI #51 which was submitted today. There is an issue w/ the exhaust duct in the east second
floor toilet. I will have John Brunner review it and get an answer
The contractor is awaiting pricing on replacing the underground sewer lines before proceeding any further
inside the building.
Observations
The installation of steel studs has gone about as far as they can on the second and third floors.
Some of the exterior grade beams have been poured. The area of the new atrium is very wet from the rain
and snow in the past several days. The inside of the building is staying relatively dry.
Ductwork installation is ongoing mostly at the second floor.
Electrical rough-in is ongoing on the second & third floors.
The contractor has started to install temporary enclosures in the north, east and west windows so the
building can be enclosed and temporary heat provided.

Estimated % of Completion: 10%
Work in Progress: Duct installation on Second floor, stud installation on second floor, forming and steel
Installation at shear walls, fire sprinkler installation on first floor
Discussion Items/Issues:
We discussed the new support detail for the existing concrete slab at the third floor so the existing concrete
all above the structural beam could be removed for the installation of ductwork.
I discussed the waste and vent piping to the drinking fountains on the second and third floors which was
questioned in RFI #50. We found a way to route the piping and keep from requiring a bump out in the
walls of the adjacent walls. I also discussed the locations of the three sinks on the third floor that will be
added with the casework.
I was informed that the measuring of the walls at the existing east and west exterior windows are not as far
out of plumb and was first thought. Last week we thought that some of the openings exceeded 2” out of
plumb in the 7’ opening. Apparently the laser was not working correctly and it now appears that the
maximum is about 1 ½” which is still significantly out of plumb.
Observations
The installation of steel studs is continuing on the second floor. The first floor shear walls have been
poured and work is continuing on the upper floor shear walls.
Work has begun on the exterior grade beam starting at the east end of the building.
Ductwork installation is ongoing mostly at the second floor. Fire sprinkler pipe installation is proceeding on
the second floor and some piping has started on the first floor.
Electrical rough-in is ongoing on the third floor and some work is starting on the second floor.

Work in Progress: Duct installation on Second floor, stud installation on second floor, forming and steel
Installation at shear walls
Discussion Items/Issues:
Carl had some questions regarding the removal of existing concrete at the second floor to install ductwork.
This was addressed in RFI #29 but the angle called for does not allow the required size of duct. I will
discuss this w/ the structural engineer to see if there are any alternative ways to support the existing concrete
third floor slab above the area in question.
Nunn has laser shot a plum line in the west window openings on the second floor. The existing concrete
structure is out of plum in all directions and the concrete surfaces on the exterior are not even in the same
plane around the opening. The three openings on the west side are a maximum of about 1 5/8” out of
plum in the east/west direction. One of the openings on the east side of the building was 2 ¼” out of plum.
We will need to provide a solution to the window detail before Nunn starts blocking at the openings.
HPE has exposed the existing sanitary sewer line in several locations to determine the condition of the
existing lines. UCCS is evaluating whether they should replace the piping at this time since the existing first
floor slab was removed making the replacement of the pipe much easier at this time.
Observations
The installation of steel studs is continuing on the second floor. Most of the third floor studs which can be
installed at this time have been completed. Work is ongoing on the new shear walls in the existing building.
Most of the steel is in place on the walls.
Work on the subgrade of the new atrium is ongoing. The contractor is preparing to form the grade beams
at the new addition.
Ductwork installation is ongoing mostly at the second floor.
Electrical rough-in has begun on the third floor.

Estimated % of Completion: 7%
Work in Progress: Duct installation on Second & Third floors, door frame installation on second floor,
stud installation on second & third floor
Discussion Items/Issues:
There were several locations where access to the VAV controls was limited. HPE was in the process of
moving one of the VAV units. We discussed the location of one of the VAV’s in hall 358, which the access
panel was just a couple inches from the existing stud wall. HPE will relocate the access panel to make it
accessible. There was a conduit directly under one unit in room 356, Carl will see that the electrical sub
moves this conduit so it doesn’t interfere w/ the controls. The last unit was over the new location of door
300G. This partition does not need to run to the structure above so a header will be installed just above
the ceiling which will then allow good access to the VAV box.
Carl and I discussed the partitions which are on window mullions at the east and west walls on the second
and third floors. Carl has coordinated w/ the window sub to make sure the mullions will be located on the
installed walls.
Observations
The installation of steel studs is continuing on the third floor. There is still some stud partitions that need to
be installed at the east end of the building. The wall change in the east end issued last week has been
followed in that area. The door frames are being installed on the second floor.
Compacted fill is being installed in the area of the new atrium.

Discussion Items/Issues:
Carl & I looked over the third floor coordination drawing and discussed several locations where the walls
will be thickened to allow roof drainage piping to be in the wall.
HPE has provided a coordination drawing for the second and first floor ceilings and the sprinkler sub has
also provided their coordination drawing for all three floors. I will review and give any comments required.
The area at the combustion air intakes was measured so I can provide a drawing for enclosing this area
with a wall inside the second floor mechanical room so the ductwork can remain as existing.
Observations
The installation of steel studs has begun on the third floor with a large percent of the studs installed in the
western half of the building. Almost all of the door frames are installed on the third floor.
The drilled piers have all been poured in the area of the new atrium. It rained overnight and some during
the day today so work on the grade beam forming was delayed today.
Work on ductwork on the second and third floors is proceeding.

Over excavation in area of new atrium
Discussion Items/Issues:
The demo subcontractor demolished a grade beam which was to remain on column line F between column
lines 1 & 3. Carl will submit a RFI so the structural engineer can review the situation and recommend what
should be done in this area.
We are still awaiting a response from the mechanical engineer on the combustion air for the boilers. This
decision impacts the floor infill in the second floor mechanical fan room.
There are 6 pipes on the exterior of the building which come from the existing boilers. We need to
determine what can be done w/ these pipes as they can not stay on the exterior of the building as they are
currently. I will have the mechanical engineer review this issue.
We reviewed the third floor above ceiling coordination drawing and found several issues with the roof
drainage piping which were discussed earlier and had not yet been changed. Nunn will review this with
HPE to resolve the problem locations.
Observations
The walls have been laid out on the third floor in the west quarter of the building. The installation of door
frames in this location has begun.
The over excavation in the area of the atrium is in progress. Drilled pier installation is scheduled to begin
next week. The cages of reinforcing for the piers were being assembled.
Work on ductwork on the second and third floors is proceeding.

We had a discussion w/ the HPE foreman about some areas on the first and second floors where there are
some problems w/ the existing structure. I will need to discuss these areas w/ the structural engineer and
the mechanical engineer. HPE will be submitting RFI’s on these issues.
A first floor above ceiling coordination meeting was held yesterday and several issues were resolved. They
are finalizing the 2nd and 3rd floor coordination drawings for my review to check the roof drainage piping
locations.
Observations
The structural remediation of installing a 6” stud along the concrete beams at the double tees is complete on
all floors.
Ductwork installation is continueing on the third floor and straps for ductwork have been installed in most of
the second floor.
Steel has arrived for the drilled piers and cages were being tied. Layout for the atrium drilled piers has
started and the area of excavation for the atrium is laid out and work will begin shortly on that area and
piers will be drilled next week.

Removal of site concrete on south side of building
Discussion Items/Issues:
We reviewed the outstanding RFI’s. Several were resolved w/ the HPE foreman. Nunn has established the
new first floor elevation of 100’-0”. They also were able to establish elevations at the second and third floor
which relate to the 100’-0” on the 2 line along the south side of the building. They were slightly different
that we had determined from the previous elevations. I will re-evaluate the second and third floor elevations
based on these more reliable elevations and issue a new IB which will replace IB #3.
The demo of the existing first floor is complete. CTL has been out to observe the soil condition and was also
out again today to see the last area on the west side of the building which they had not observed. CTL has
delivered their recommendations on the soil treatment prior to the installation of the new slab. We will not
have to remove and replace the existing soil and it will just need to be recompacted to the proper density.
Carl and I discussed the third floor coordination drawing which I received yesterday. I am concerned about
the location of some of the roof drain leaders. I discussed these w/ HPE several weeks ago and the drawing
I received did not include any of the issues I had discussed. Carl will talk w/ HPE about revising this drawing
and providing a new drawing w/ the proper locations of the roof drain piping.
Observations
The structural remediation of installing a 6” stud along the concrete beams at the double tees is complete on
the second and third floors and was in progress on the first floor.
Ductwork installation is proceeding on the third floor and straps for ductwork have been installed in most of
the second floor.
The area of roof which has been removed has been infilled w/ a temporary structure and has been
waterproofed to prevent moisture from entering the open grade at the first floor.
8-24-06 CONSTRUCTION FIELD REPORT
Estimated % of Completion: 4%
Work in Progress: Demolition first floor slab & duct installation on the third floor
Discussion Items/Issues:
We reviewed IB #3 which establishes the new first floor elevation 100’-0”. The elevation will be
established as approximately ½” below the entry to the northeast stair and approximately ¾” above the
entry to the northwest stair. From this elevation, the contractor will establish the elevations at the tie
between the existing 2nd and 3rd floor and the new floors at the atrium.
Nunn proposed to cut a hole in the floor above the locations of the new shear walls so the new concrete
can be installed through these holes. I will check w/ the structural engineer to see if this method is
acceptable.
The demo of the existing first floor has begun and the slab in the area of the new lecture hall has been
removed.
Observations
The demolition work is nearly complete with the floor slab removal remaining and some additional
sawcutting left to finish.
Straps for ductwork have been installed in most of the third floor. There is some fabricated ductwork on
the third floor and one of the ducts has been installed between the double tees.
8-17-06 CONSTRUCTION FIELD REPORT
Estimated % of Completion: 3%
Work in Progress: Demolition & work on duct hangers on the third floor
Discussion Items/Issues:
We discussed the existing louvers in the south walls of the stairs where the mechanical units are being
removed at the top of the stairs. The demo drawings call for these existing louvers to be blanked off w/
sheet metal and Carl will install a layer of rigid insulation on the inside of the louver.
The concrete topping at the existing outdoor second level patio was not installed according to the drawings
and is somewhat higher that the existing interior slab. Before any further work in done on this slab, we need
to determine the elevation of the connection from the new atrium levels to the existing building which may
result in a thin topping being required at the patio area rather then removing more existing concrete.
The contractor had some questions on the existing outdoor area where the new chiller and emergency
generator are located. He will get an RFI which will locate the existing concrete pads and curbs so CRA can
verify how the new chiller and generator can be located.
The demo of the existing first floor slab is to begin on Friday so the CTL can perform some testing to
determine if additional remediation will be required below the slab.
The contractor will propose a possible new solution of adding the steel plate at the existing concrete beams
to capture any potential spalling. I will have the structural engineer review their proposed solution to see if it
is acceptable.
Observations
The demolition of the south wall is continuing and the only thing remaining is some work on the existing
stair and some saw cutting of existing concrete walls.
The weather finally broke a bit and the asphalt for the fire lane was installed so the students and fire
department now have access to the south of the construction area.
The second floor is nearly cleaned out with all the existing piping, ductwork, etc. Straps for new ductwork
have been installed on the third floor.
8-03-06 CONSTRUCTION FIELD REPORT
Estimated % of Completion: 2%
Work in Progress: Demolition
Discussion Items/Issues:
RFI #9 was discussed. A new support will be required to support some masonry and a concrete beam at
the second floor stair entrance to the northwest stairs. I will discuss w/ John Brunner and respond to the
RFI.
Work is proceeding with the storm line which will daylight in the lawn south of Main Hall. This line runs
between two of the existing elm trees south of Main hall. I reiterated the necessity to protect these elm trees
during this pipe installation. Carl noted that the installers have been informed to take great care to not
damage these trees.
We had a discussion on the conditions at the first floor slab. There is a differential of 4 ½” from the high
to low spots on the floor and the entire floor varies significantly in relatively short distances. It appears we
will have to remove the entire first floor slab and test the subgrade to determine if any additional
remediation will be required prior to the installation of a new concrete floor slab. We need to get
recommendations from the soils engineer so that any new movement will be minimized.
Observations
The hard demolition of the south wall is continuing. The existing main south stair is being demolished.
The sawcutting of the concrete on the east and west windows has begun. Some of the sawcuts will require
significant grinding to smooth the edges. Most of the columns are not exactly plumb and this didn’t allow
the sawcuts to be exactly parallel to the column edge. The grinding will be covered w/ the installation of
the new windows.
Work on the storm drain is proceeding with the intention of completing the work on the line prior to the
beginning of classes. This work impacts both the pedestrian and vehicular traffic between Main Hall and
Dwire.

7-27-06 CONSTRUCTION FIELD REPORT
Estimated % of Completion: 1%
Work in Progress: Demolition
Discussion Items/Issues:
RFI #6 was discussed. The concrete wall on col. Line D between 2 & 3 is not structural and can be removed as per the drawings. There is an issue with the location of the fiber line in the great lawn in front of Main Hall where the new storm sewer outlet is being installed. Cheryl Bean is to go on site this afternoon and review the situation and find a solution for avoiding the existing fiber line.
Observations
The abatement work is finally complete. The only thing remaining is the trash dumpster which is scheduled to be removed shortly. The hard demolition of the south wall has begun. All of the concrete tee’s from the roof have been removed. The parapet wall above the roof line has been removed and most of the second and third floor demolition is complete. Demolition on the first floor is ongoing. Most of the drywall walls have been removed but the CMU and brick walls on the first floor are still remaining.
Work has begun on the site utilities in the area between Main Hall and Dwire. This will make the traffic situation very difficult during this work. Nunn is trying to complete this work before 8/16 so which school is back in session most of the work in this area will be complete and the road between Main and Dwire can remain open most of the time.
7-27-06 DETOUR REPORT
Affective Thursday, July 27 through August 16th, the pathway from University Plaza to Main Hall
(in front of Dwire Hall) will be closed to all pedestrian traffic. In addition, the one-way lane between
Dwire Hall and Main Hall to
south west side of Science Building will be closed.
This is a mandatory closing due to reconstructing of Fire Lane and sidewalks affiliated with the Dwire Renovation Project.
For the time being, all pedestrian traffic coming from Main Hall to University Center should exit through
Cragmor Hall to roadway (cones are set up giving a lane to pedestrians) in front of Lot 2 continuing to
sidewalk in front of
Science Building and vice versa.Please pay attention to detour signs and traffic,
especially the first couple of days as there will be some confusion (this is to be expected).
7-20-06 CONSTRUCTION FIELD REPORT
Estimated % of Completion: 1%
Work in Progress: Abatement, Demolition
The abatement work is continuing on the first floor. The demolition work is proceeding primarily on the
second and third floor. Most of the exterior windows which are to be removed have be demolished and
most of the partitions on the upper two floors have been removed. The abatement contractor has not
completed their work which is delaying the work of demolishing the exterior south wall as had been
planned.
7-19-06 First off, to introduce myself, my name is Dwayne Freeman. I am one of two new Construction Project Managers. The next couple of years are going to be very busy as you already know.
I am going to run monthly walks through one of my projects, Dwire Hall. As you all know this is a welcomed and needed project and we are moving ahead nicely. Demolition has started and should be done here in 2-3 weeks. That will be my first scheduled walk to anyone interested. If you are interested send Dwayne Freeman an email. I will send out a notice of date and time. I think people enjoy watching construction in its different phases and want everyone to be part of that process.
There are a few ground rules: 1. Hard Hats 2. Safety Glasses 3. Hard sole shoes (no flip flops, open toe etc. etc.) Also, I would like to add that the date and time is not negotiable. We have a schedule to keep and Nunn Construction has been nice enough to allow us to do this. They will be setting the schedule for these walks at their construction schedule convenience.
