The week of April 27-May 2, 2003
Contractors poured the 3rd floor South slab and also the South stair steps (2nd to 3rd floor). They installed a drain at the South airway and poured a temporary curb around the airway pump to stop water and mud from entering our building. Other workmen continued mechanical and HVAC rough-in in the sub-basement. Block work continues in the basement and concrete was poured into the block. Workmen formed the 3rd floor for slab pour on the North side of the building. They also continued to fabricate and hang chill water pipe in the H & R building. Finally, workmen from ABC Saw Cutting cut through to the existing building, while contractors took action to secure the construction site from our main building.
The Week of April 20-26, 2003
This week contractors poured the north stairwell between levels 2 and 3 and also poured columns between that same level. They formed the deck for the 3rd floor and also started installing rebar on that same level. They continued installing cement brick walls in the basement and also insulation on the basement walls along with damp-proofing the basement. At the Heating and Refrigeration building, electricians performed rough-in of the mechanical areas as well as electrical rough-in. They continued to install metal roofing on the H & R building deck. On Friday, subcontractors off-loaded large mechanical underground piping for future installation.
Week of April 13-19, 2003
Contractors formed, rebared and poured the North and South stairwall and the elevator walls from the 2nd to 3d floor. They also formed and poured 27 columns from the 2nd to the 3rd floor. They formed ½ of the 3rd floor slab on the South side of the building. Sub-contractors also installed concrete blocks in the sub-basement, while others installed duct and mechanical piping in the sub-basement.
Week of April 7-11, 2003
This week, contractors poured the 2nd floor slab on the north end of the new wing. They also constructed forms and rebar coils for the south stairwalls, elevator walls, from the 2nd to the 3rd floors. They also continued work on the HVAC system installed in the basement. Other sub-contractors fabricated and hung 8" and 10" chillwater and condensed pipe in the H & R building as well as in the sub-basement. Electrical rough-in is ongoing. Other sub-contractors dug a hole for an 8' X 8' electrical manhole at the H&R building. At the end of this week, they also started excavation in support of equipment at the electrical vault on Adams Ave.
After two days of rain this week, we experienced clogged drains and a surge of mud inside our building sub-basement. In an attempt to find the problem source and correct it, a change order was submitted for the contractor to remove the parking pad adjacent to the building's S/W entrance. Upon exposing the hole we found a cavity approximately 3' X 5' deep where the dirt had washed out under the pavement and found its way into the building. The contractor subsequently removed a sump pump and concrete bottom in an adjacent drain pit. That drain was abandoned. A new sump pump was temporarily reinstalled and any standing water will be re-routed away from the building. This interim fix should resolve the drain problem until major sewer drain work is done on the building in June '03.
March 31- April 4, 2003
This week, subcontractors poured half of the 2nd floor elevated slab on the North and South sides leading to the 3rd floor level. They installed rebar and formed elevator walls from the 2nd floor to the 3rd floor. They also formed the South stair walls leading from the 2nd to the 3rd floor. Duct work continued in the sub-basement and sub-contractors also started work toward installing 12 inch pipes in that level. In the H & R building workers continued electrical rough-in.
