As formwork within the CY has been completed, the space has become very congested.



With the building tented in with plastic, Scott Hall is becoming a distinctive part of the Oakland landscape, both night and day.

407 408


Each of the floors in the north wing have been poured in 2 pours.  The images below depict the break line of the two pours. 

404 405

Crews finish forming the courtyard columns in preparation of the scheduled pour.  Due to the columns' height, extensive shoring is required to hold the formwork in place.



The building trap is being installed at the lower lot.  This is the last connection from the building to the PWSA tie-in.  At the same time, the new steam line that runs across the site is being installed.  This replaces the old line that has been temporarily rerouted for the past 1.5 years.

401 402 403


The building continues to be tented in.  This will allow crews to continue working on Scott Hall throughout the harsh winter weather.  Additional site work continues to reconnect the steam line that once traveled across the hillside.  The new steam line will now travel beneath Scott Hall through to FMS from Roberts Hall.  Excavation/backfill continues for the Sanitary tie in under Hamerschlag Drive at the lowest portion of our site.  This new tap will facilitate all of Scott Hall waste water, a good percentage of storm water will be diverted from PWSA's combined storm/sanitary system.

The Cleanroom slabs have all been poured to date.  Prep work for the concrete columns has begun.  Forming columns will take place over the next month.


Steel erection has been completed and the crane was disassembled and removed from the site on 11/1/14.  The steel erectors continue to weld connections and set decking.  While decks are released to sub-trades, inserts and embeds are installed in preparation for slab pours.

Curtain wall embeds are being installed around the perimeter of the building.  These boxes will be cast into the concrete floor slab, and they will carry the load of the curtain wall system (glazing, mullions, and dichroic glass).  The embed are designed to allow for vertical and horizontal adjustment for proper curtain wall alignment.

The caisson coordinates within the new pump room have been surveyed and will be drilled within the next week.


The Hamerschlag Shoring wall has been completed.  The remainder of the sanitry reroute will take place through the next two weeks.

139 140




Caissons are currently being drilled and poured where the salt bin once was.  Once these caissons are completed, tiebacks (pictured and described below)  can be installed in the main shoring wall.  This will allow for the remaining excavation of the north wing hillside, and accommodate drilling of the remaining caissons.

134 135 136


Tiebacks, shown in the photos below, are steel cables that are inserted through shoring wall piers that act as an anchoring mechanism for a retaining wall that is being installed.  Essentially the tiebacks are supported by the mass of earth that the shoring wall is designed to retain.  The images below show that all tiebacks have been installed.  The courtyard area will be excavated approximately another 12' to allow for the construction of the new pump room and the final relocation of the sanitary line shown piped in these photos. 

130 131 132



The removal of the Wean Hall areaways has allowed for the lower portion of the sanitary reroute to be completed.  During the excavation, a foundation drain for Wean Hall was found and has been tied into the sanitary reroute.  In order for the sanitary reroute to be completed, a shoring wall against Hamerschlag Hall had to be installed to allow for the deep excavation so close to the building.  The shoring wall is currently being installed, and grade will be excavated approximately 12 feet below its current level.  This excavation is not only for the installation of the sanitary reroute, but also to construct a lower pump room that will service the new and existing services.

The excavation of the courtyard continues to progress.  Currently the majority of dirt has been removed through the Porter Parking Lot.  We remind pedestrians to follow posted safety signs while near construction zones.

086 088


Drilling of the first caisson is nearly complete.  The rebar reinforcement cage, which will go into the newly drilled hole, is situated in a staging area.  Once the rebar is installed within the hole, concrete will be pumped in place which will create the caisson.

089 090 091


The shoring wall process begins with the drilling for shoring piles which are steel columns that will have wire tendons shot into the earth behind the wall to keep this from caving in.  Once the piles are installed, wood lagging is used to temporary hold dirt behind the wall back while the dirt in front is excavated.  Once the excavation reaches the correct depth, concrete panels will be place between the steel piles, which will remain as the permanent shoring structure.   

084 085


The outer chiller wall has been removed and dirt is being removed from the courtyard to prepare for the new pump room construction.

082 083


Drilling on the hillside has begun.  Soldier piles for the permanent shoring wall are being drilled currently.  Once the wall pile are drilled and set, the contractor will move to caissons across the hillside and within Hamerschlag Drive.

078 079

080 081


The retaining wall from the original chiller location has been removed and dirt is being excavated from the courtyard.  The excavation throughout the entire courtyard will drop the elevation by approximately 10' to allow space for an engineered fill material and the construction of the new concrete floor slab.  We would like to remind pedestrians to stay out of marked construction areas for their safety due to the high level of construction activities.

076 077


The second chiller has been relocated and piping is currently being installed.

074 075


The chilled water reroute through Hamerschlag D Level has been completed.  The water lines are running with no issues.

An adjacent University Project, Masonry Restoration, is underway on Wean, Hamerschlag, and Doherty Halls.  The scope of work includes repairing damaged and spalled concrete to Wean Hall by hammering and sawing necessary areas, patching, and sealing the entire facade.  Hamerschlag Hall will be re-pointed in damaged regions with minimal brick replacement.  The arched masonry underside of Doherty Hall will be removed and re-supported with steel support brackets.  This work will continue alongside the Scott Hall construction, however if you feel disrupted by the masonry repairs please contact your building's Facility Director or Karen Spells Attn: Edward Hydzik with Campus Design Facility Development.

Work scheduled:  Masonry contractors will be cleaning and removing caulking on the south elevation mall area of Wean.  They will continue cutting and grinding on the west and northwest side of Wean.  Removal of the brick and granite lentils on the Doherty Bridge will continue, and welders will also be installing support brackets.


Exits in the courtyard are starting to be affected by demolition and other construction activities.  Please review the detour maps above for a description of proper exiting procedures and paths.


The first chiller was lifted into place today.  It will take the remainder of the week to pipe to the chiller and complete the hookup before the 2nd chiller can be relocated next week.
