    North side of Lincoln wiith new paneling

    As each month passes more progress can be seen both inside and out of the new Lincoln High School. Late summer has been a busy time on the project.  Various activities are happening throughout the site as certain areas are in different stages of construction.

    Plumbing and ductwork rough-in is taking place on the first two levels of the south section of the building in and near the Music, Health, PE, and Culinary Arts classrooms. Duct insulation is being installed on the 6th floor of the classroom tower.

    Electrical work is happening on the first two levels of the south areas of the building. Security system and fire alarm wiring has started in this same portion of the building, and continues on Level 6 of the classroom tower.

    Building interior work includes elevator installation in the north area of the building. The elevators will connect all 6 floors of the classroom tower. Other interior work includes final drywall and plaster on the 6th floor of the classroom tower. Framing and drywall is also taking place on the 1st and 2nd floors in the south portion of the building and in the Auditorium. Painting is following close behind the drywall and plaster work in the classroom tower, as are ceilings and flooring. Casework which will provide space for curriculum and supplies storage is being installed in the classrooms as they near completion. 

    On the outside workers are adding the weather barrier at the exterior wall which faces SW 18th Ave as well as at the wall which faces the future pedestrian plaza on SW 17th Ave. Other exterior work including the lower roofing area, and wall insulation and supports for the remaining exterior panels. Those exterior finish panels are colored a deep red and are made of ultra-high-performance concrete (UHPC). They are now being installed on the exterior wall facing SW Salmon St.

    Lincoln gym framing

    LHS construction has made significant progress since the topping out ceremony. Crews are working on the building exterior, the mechanical systems, and on the interior framing and floor slabs. The gym, which is on the second floor of the building, now has its structural floor in place and the concrete floor will soon be poured.
    HVAC unit lifted by crane

    The building's mechanical and HVAC units arrived on site and the crane operator lifted them into place for final attachment on the roof.

    window installation & caulking

    Windows are installed in most of the classrooms and the glass enclosure (curtain wall) is being installed at the circulation and stair areas.

    welding in auditorium

    In the new auditorium the catwalks and rigging are being installed.

    framing and insulation in classroom building

    The six story classroom building is seeing framing, insulation and drywalling taking place at various stages depending on the floor.

    Topping Out Ceremony

    During January the steel framing work continued and was formally celebrated with a Topping Out ceremony on Friday, February 5th. More about the topping out tradition here. Once the steel structure is complete,  interior wall framing and the pouring of the concrete floors will follow.  See a video of the Lincoln Topping Out Ceremony here.

    Construction on the building exterior has progressed significantly. Hoffman Pacificmark is building the exterior walls by constructing modular panels of the wall framing, insulation, and weather membrane that are then lifted into place and connected to the steel structure. Once the panels are installed, the window units are fastened into place. The next steps for exterior wall construction include finishing the window installation and finalizing the connections between panels. The blue surface seen on the outside face of the panels is a "peel and stick" membrane material that is an important part of the engineered weather enclosure than enhances energy conservation.

    Lincoln construction Feb 5th

    Steel stairs are being built into the northwest corner of the building at SW Salmon and 18th, and on the east side of the building near SW 17th and Salmon. These stairs will be enclosed with glass walls and provide the main vertical pathway to and from Lincoln classrooms.

    On the building interior the primary structure in the theater is nearing completion and interior framing of walls is progressing on the upper floors. The team recently reviewed a classroom mockup to confirm how teaching technologies will be installed. Mechanical/Electrical/Plumbing (MEP) systems are being roughed in at all levels of the classroom tower. These systems include HVAC ductwork, plumbing, fire sprinklers, and electrical wiring. This will be followed by interior wall framing which is now taking place on Level 2 and 3 of the classroom tower.

    The  work for the gym enclosure and support also continues. Now the South wall for the gym has reached its full height and workers have moved to the east-facing wall which will feature large windows looking out toward the track and field. The sequencing of the concrete masonry work and steel framing requires careful coordination by the contractor so that connection points for the steel will be ready at the right time.

    Steel work at on the newLHS

    The last several weeks have been very busy at the LHS site as the school continues to rise up out of the ground toward its eventual six story height. Steel erection started in late September and will continue for a number of months.

    Steel frame of the first three floors of the new LHS building

    The structural steel system features a SidePlate connection system for the seismic force-resisting joints in the frame. This design and construction approach is very efficient both for how quickly it goes up in the field, as well as for the long-term flexibility of interior spaces in the school.

     Gym wall and tilt up theater walls

    The concrete tilt-up walls for the theater, that had been poured a few weeks earlier were lifted into place by a large crane during the first week of October. Tilt-up walls are an efficient system for enclosing large and tall spaces like the theater.

     close-ups of the engineered bracing

    This photo shows close-ups of the engineered bracing which is used to stabilize the panels as they are secured in place.  The LHS project team are using this system to reduce the construction time. The concrete panels are first poured and allowed to cure for a few weeks prior to lifting into place.

    Construction of the CMU (concrete masonry unit) walls on the southeast side of the campus continues and is now up at the second-floor level. These CMU walls form the enclosure to the new gym. The photo above shows the "mules" which are equipment being used by the masons to maintain safe social distancing between workers and to keep the overall speed of production on schedule.

    Working attaching steel beams

    In the coming month there will be more steel framing visible on the second floor, with structural connections to the theater and gym walls. The steel decking will also be installed on the upper floors of the structural frame. This work will provide connection points for utility supports for the mechanical and electrical systems in the building.  To see the latest photos click here.

    Lincoln SW Wide Aug 2020

    Lincoln Rebuild Project has made significant progress on the foundation and in ground utilities in preparation for when structures will start rising up from the ground. 

    Concrete buffing Lincoln aug 2020

    Finishing concrete work with the buffing machines is occurring in the Dance / Wrestling room. 

    Lincoln Library foundation Aug 2020 In the Northwest corner of the site the foundation of the library is well developed and ADA ramps have gone in.

    July/Aug 2020

    Lincoln framing wide

    Lincoln Rebuild Project is beginning to take shape with significant foundation work underway and several structures rising up from the ground. Over the last month there has been much activity to complete the foundation and subgrade waterproofing to make way for the completion of school’s ground floor concrete floor slab.

    Lincoln shotcrete

    Concrete foundation walls at SW 18th and along the South property line area we created this month with shotcrete.  A construction technology that literally blows concrete into pre-framed walls. Additional foundation work includes concrete slabs at the theater orchestra pit and seating area, as well as the locker rooms.Concrete work is also starting to take shape in the form of support for the gym; it can be seen at the wall in the South half of the building.

    Lincoln foundation pour

    Other site infrastructure work that happened this month included:

    ·      The utility connections have been installed.

    ·      The radon mitigation system is being constructed; it includes layers of rock and piping that are installed below the ground floor concrete slab.

    ·      A vapor barrier was put in place at the library, main floor offices and school entrance in preparation for the concrete slab pour.

    Lincoln formwork

    Hoffman Construction has completed the deep foundation work on the augercast piers, the foundation for the orchestra pit, and the enclosures for the elevator pit. The construction team is now building the walls around the orchestra pit and at the classrooms along the South and West edges of the site while they work to complete the augercast pile caps.

    Augercast piles are a deep foundation system made of reinforced concrete piles or piers that are cast in place with steel reinforcement. The construction photos show the pile cap work that is now underway. Each pile cap includes a large concrete pad and rebar connections that will be used to secure the foundation system to the building frame. 

    Lincoln tower cranes

    Along with the progress on foundation work, the construction team installed two tower cranes which will be used to maneuver large building elements. The team is looking forward to erecting the structural steel starting later this summer with the cranes. They will also be used to lift the exterior wall panels and mechanical units into place.

    The pedestrian protection canopies are being installed along the sidewalks on SW 18th and SW Salmon. They will be complete before the end of this month and then the construction fence location will be adjusted in order to open the sidewalks to the public.

    Lincoln Aggregate pier work

    Early spring sunny weather has provided construction teams to move along briskly so mass excavation is complete and the building footprint is now visible on site. Foundation work is proceeding on schedule with shoring walls complete and the aggregate pier installation over half way done. Much of the deep underground utilities work including electrical, gas, and plumbing piping is being completed in advance of the aggregate piers work.

    Aggregate piers are columns of highly compacted stone that are installed in groups to increase the weight bearing pressure of the building’s foundation and to prevent later settling. Special equipment is used to compact the stone in the holes to make the piers.

    The project team is working closely with neighbors and LHS to monitor impacts from construction activities through frequent in-person conversations at the project site, as well as by gathering data from vibration monitoring equipment installed at numerous surrounding properties.  View the March construction pictures here.

    Lincoln underground utilities

    January 2020

    The Lincoln project is now underway and big changes are already visible on site. Over the holiday break, the Hoffman Pacificmark team mobilized, setting up the construction fence and moving in some construction equipment. The complex of trailers, which will be the project team’s base of operations throughout construction, are in the process of final assembly. The reconfigured staff parking lot is in place providing safe access to LHS.

    Hazardous materials abatement for the grandstand, press box, and two small storage buildings under the grandstand was completed in December; those structures have now been demolished. With the site area is cleared of structures, it is being leveled using trucks and heavy equipment. The turf field removal is complete.

    Lincoln construction site

    To build the work area, Hoffman Pacificmark used 10,000,000 pounds of recycled concrete saved from a local project site for the leveling fill and rock substrate. This recycled material will remain in place to provide support for the future track and field. This recycling effort kept a significant amount of material out of the waste stream providing both material and cost efficiency for PPS.

    The construction entrances and exit, on SW 17th and Salmon and SW 17th near Jefferson respectively, have been established. The protective canopies over the sidewalks on SW 18th and SW Salmon adjacent to the future Lincoln are in the process of installation. The next major construction activities will be final site preparations and the start of foundation work.

    Groundbreaking for a new Lincoln
