Hamerschlag Drive Closure Detours
*During the above mentioned closures, please reference the maps below for detailed firstname.lastname@example.org or 412-268-8936.
*Please note that portions of work may produce noise within the immediate area, and all efforts will be taken to reduce any noise. We apologize for any inconvenience, and we appreciate your understanding and cooperation during this time.
Progress to Date
Please see below for items of importance and photos depicting current work on the Scott Hall Project, Thank you.
Wall forms and rebar are in place for the new pump room foundation. Concrete is scheduled to be poured Monday, 3/3/14.
Foundation walls in the courtyard pump room are being formed and rebar is being set. This process will take approximately 1.5 weeks and concrete can be poured subsequently. Work continues with mat 3 foundations and caisson drilling on the hillside.
The project team refers to the largest mat foundation pad for the project as "Mat 3". This foundation essentially acts as an anchor for the portion of the building that cantilevers over the hillside. Mat 3 formwork and rebar has been installed concrete is being poured. There is approximately 216 cubic yards of concrete just within this piece of the foundations; that's 24 concrete truck deliveries.
The foundation wall forms are being installed as rebar is completed for the new pump room.
Foundation walls are being formed within the pump room space, while the mat 3 pad(3rd photo) is being finalized for concrete to be poured.
18 trucks of concrete were delivered on site today for the pump room grade beams and pile caps. 15+ workers were on site and coordinated the concrete trucks and pump with the pour locations.
Outpak Washout boxes provide LEED certified disposal of slump testing on site. Slump testing is essentially placing an amount of concrete outside of the forms to ensure the proper mixture thickness and fluidity. To ensure there is no contamination to surrounding areas, this product allows an easy, clean, and safe alternative to on site slump testing.
As you can see below, the pump truck had a reach of over 150' to deliver concrete to the proper locations. As a testing requirement, concrete sample cylinders are collected every 50 yards per the engineers specified testing requirements. The cylinders shown here are only a small handful of what has been collected to date. These cylinders will be tested, by breaking them, at certain cure intervals to ensure the concrete is meeting the specified strength.
Grade beam and pile cap forms are in place. Final heating preparations will need to be done prior to the scheduled concrete pour.
The Pittsburgh Fire Department visited the construction site today for a inspection to review temporary exit strategies and detours. There are 8 exits that have been affected by the construction.
The ramp and stairs have been removed from both locations on Wean Hall. These exits have been closed for the duration of the project. A walk through with the city fire department is scheduled for 1/20/14 to review exit paths and detours. Pile cap forms and rebar are being installed. Concrete for the pump room and large elevator(mat 3) pile cap is expected to come during the week of 1/27/14. Installation of the main shoring wall tie-backs are continuing; approximately half of the tiebacks have been installed.
The concrete stairs connected to Wean and Porter Halls is currently being demolished. This demolision should wrap up within the next week.
Pump room pile cap rebar has been delivered and pile caps are being formed. The new loading dock are is being excavated to form pile caps.
Caissons within the pump room have been completed. Next, pile caps and footings will be formed and poured. The shoring wall tiebacks are scheduled to begin now that all caissons are completed in this area.
The construction crew continues to drill and pour caissons on the hillside and within the pump room.
The construction site is teaming with activity as 2 rigs drill caissons, multiple excavators prep for caisson locations, and a crane is situated to install caisson reinforcement. Crews are currently drilling caissons for the southern splayed column clusters, and within the pump room. 57 caissons have been drilled and poured to date.
The FMS salt shed has been completed and is ready for salt to be delivered.
A Town Hall Meeting will be held today from 5-6pm in McConomy Auditorium. Please follow this link for the presentation that will be given at the meeting.
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.
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.
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.
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 campus salt and mulch storage has been relocated to the lot across the tracks. The base of the storage bins have been asphalt paved and concrete foundation blocks have been arranged in U-shaped configurations. The finishing touch will include barrel-arched roofs to protect the bins from the weather. Please see the series of photos below depicting the construction of these storage bins.
The lot across the tracks has been graded, and a stone drive is being installed to access the new location for the FMS salt shed and mulch pile. A new entrance from boundary street has been created to stay the proper distance away from the Railroad tracks.
Excavation at the western portion of Wean Hall has completed for the removal of the concrete areaways beneath the transformer garage doors in the photos above. These concrete areaways will be removed to allow for the construction of the new Scott Hall elevator mat slab foundation.
The lower manhole is being set within the excavation for the sanitary reroute.
The temporary sanitary reroute within the courtyard has been installed. This reroute diverts the sanitary away from the existing route while the new permanent line can be installed.
Work on the shoring wall continues, while the storm/sanitary line within the courtyard is temporarily rerouted. The storm/sanitary line will be permanently reouted after the excavation and shoring activities within the area are complete.
A group of students from the School of Architecture who have based a construction practices course around the Scott Hall Project receive a tour of the site.
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.
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.
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.
The outer chiller wall has been removed and dirt is being removed from the courtyard to prepare for the new pump room construction.
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.
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.
The second chiller has been relocated and piping is currently being installed.
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.
7/17/13Exits 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.
The new construction has been delivered to the Porter Parking Lot. The electric and data will be hooked up next week and the construction team will begin moving in the following week. Also, the nitrogen pad has been formed for the relocation.
The demolition of the salt bin continues. Multiple utility lines(abandoned and active) have been found under and near the excavation site. It has been noted that the salt bin was constructed on the same foundations of an original coal hopper that fed Hamerschlag Hall. These foundations are being excavated also, which has led the excavation to lower elevations than anticipated.
In order to prepare for the Cleanroom Chiller relocation the Hamerschlag server room roof has been removed. This space will be prepped for the first chiller relocation scheduled for 7/15/13.
The chilled water reroute has been backfilled and Roberts Drive has been returned to normal use. Final backfilling remains within the FMS loading dock are. The excavated areas will be re-paved in the coming weeks.
The reroute on upper Roberts drive is finalizing and the road will be backfilled by the end of next week.
The new chilled water lines have been installed within Roberts Drive near FMS. The lines will be backfilled later this week.
Spot excavations within planters and on the Wean Hall 4600 roof/plaza are being explored to supply the design team with a roof composition detail of current conditions. Portions of Wean Hall will experience intermittent periods of noise and slight vibration during the next 2 weeks. We apologize for any inconvenience.
The remaining walls of the lean-to have been removed and the excavator has begun sorting the debris for disposal/recycling.
The lean-to within the HH/Wean/Porter parking lot is currently being demolished. During this time we ask all pedestrians near the area to maintain a safe distance from the construction zone barrier. The Wean Hall fire stair egress, 4129, should be used only during an emergency.
The first casework mock-up has been delivered and assembled in Smith Hall. Two more mock-ups are expected to be delivered in the next two weeks and the fourth and final to be delivered in July.
The new water and steam lines are currently being set into place. The team will continue to set the remaining lines, shoot as-built coordinates, and back fill once complete. A coal hopper was discovered beneath the salt bin, and the crew on site is exploring the depth of the hopper and the impacts of it's removal.
The demolition of the salt bin on Roberts Drive has begun. The majority of the structure will be removed by 6/11/13.
The mechanical contractor is currently finishing core drilling the FMS foundation wall for the chilled water and steam line reroute.
Areas within Roberts Drive near the salt bin have been excavated to verify utility paths. These locations are being coordinated with the structural foundations.
Tie-in locations have been excavated beneath FMS for the new chilled water reroute.
The access road has been completed, and the end of the Hamerschlag Steam tunnel has been removed.
An access road is being cut into the site to begin the shoring wall installation.
Manhole 3 and 4 have been placed, and the contractors are setting caps and backfilling the excavated areas.
Please find attached the Town Hall Presentation given at the meeting held last night.
Manholes 6 and 7 have been set and our crew is in the process of excavating for manhole 5.
Manhole 8 has been placed and the construction crew continues work on manhole 7. Once this work is completed the Roberts Drive will be re-opened temporarily.
During the excavation for the sanitary relocation, the Hamerschlag tunnel has been unearthed and the contractors have begun to demolish portions of the tunnel to make way for the new manhole that will be installed.
Roberts Drive will be closed Monday morning for the installation of the new manholes for the sanitary maintenance.
Excavation parallel to the lower portion of FMS drive has begun to identify the exact location of the 15" sanitary line.
In order to prepare the site for the new sanitary line, the radius wall on Roberts pedestrian ramp had to be removed. A temporary set of steps have been built to maintain access to this entrance.
The contractor is on site and excavation for sanitary utilities has begun. Please see the images below for a detailed looked at this process.
Beginning Monday the Road closures to Roberts Drive and pedestrian detours will begin. Please review the maps posted above and allowed yourself additional time to reach your destination.
The new Wean Hall skylight mockup has been installed and can be found in the courtyard. This mockup demonstrates the actual height and angle of the proposed design.

Excavation work done to Roberts drive this week is wrapping up, concrete will be poured Monday, and barriers will be removed Wednesday.
Excavation work along Wean Hall parking lot will resume today and tomorrow from 7:00 am until 3:30 pm each day. Work is anticipated to be finished on Monday 11/12. Efforts will be taken by our team to minimize any disruptions as much as possible. Please watch for notices regarding future construction activities.
Excavation work will be done on Roberts Drive and will continue throughout next week. Due to safety requirements, sections of the sidewalk will be closed and pedestrians will be redirected around a construction barrier. Work on Roberts drive will continue through next week, ending 11/19. Pedestrians and traffic will be directed around the work area with cones and barriers during this time. We appreciate your patience and cooperation during this work.
The design team will join the engineers and construction team on 11/5 and 11/8 to reconcile design choices.
A banner with a rendering of the future Scott Hall has been hung on Wean Hall pointing out the location of our campus' newest addition. This addition will greatly strengthen inter-campus connectivity.
A Town Hall Meeting has been organized for Today in Rangos Hall. Design specifics of the new Scott Hall will be announced and discussed by the Architect and the Campus Design office. Please follow this link for a digital copy of the Town Hall Presentation. Below are a few renderings that will be displayed at the meeting.
Today, the ground breaking ceremonies were held for the Sherman and Joyce Bowie Scott Hall. This will become the future home of the new Wilton E. Scott Institute for Energy Innovation. Distinguished guests, donors, and select University members commemorated the event.
The Wean Hall duct bank is nearing completion with the majority of the run already buried. Gas lines were removed this week so the duct bank can continue its path into Wean Hall.
The new Wean Hall duct bank is currently being installed. The electrical conduits are encased in an aluminum duct with a mixture of sand and gravel. The shielded duct bank is buried beneath the future corridor surrounding the cleanroom.
3D modeling and clash detection has become a major method to expedite the design coordination process. Combining the consultants models allows all members of the team to visually focus on areas of the building and review issues that may arise.
A telephone and electrical duct bank have been exposed in order to plot there coordinates within the hillside. This will enable the design team to plan foundations more accurately.
Exploratory work continues. Site utilities are being located and identified. Test holes are plotted and excavated with the help of previous campus surveys and historical data. Once a utility is found, coordinates are shot and points are transferred and modeled into a 3D site model.
Starting today our project team will begin exploration work to locate approximate locations of site utilities in the hillside. Throughout the next few weeks our CM, Jendoco, will be spot excavating on the hillside to locate the paths of storm, water, steam, and electrical lines which are located in the area. A mini-excavator will be brought on site to facilitate the efficiency of locating utilities.
Efforts will be taken by our team to minimize any disruptions as much as possible. Please watch for notices regarding future construction activities. We appreciate your patience and cooperation during this work.
