OBSERVATION 4: WEEK 2 FEB 2018

PROLOGUE

The East End Transformation Project is the largest capital project ever undertaken on the Danforth Campus. It will also be the most disruptive. The following is a terrain map and schematic development map helping one locate the extent of the project and understand its various components respectively.

THE SETUP

The following plan depicts the location of the cameras mounted on permanent structures along the periphery of the site. These permanent structures are the Brookings Hall, Green Hall and Hillman Hall respectively. The daily feed from these cameras are employed to track and monitor construction progress.

PROGRESS DOCUMENTATION

The following section depicts the observations undertaken at the construction site with a focus on project progress, construction activities, materials, equipment, workers, and site conditions. The order of photographic documentation is the perspective from Brookings Hall, Green Hall and Hillman Hall respectively. Each unique photograph is followed by a comparative to depict progress compared to the preceding work week.

This research will be confined to observing the construction progress of the Henry A. and Elvira H. Jubel Hall (3) and the Underground Garage (8) for the 2nd week of February 2018.

 

EQUIPMENT MOBILIZED: Tower Crane (#3), Truck-Mounted Concrete Boom Pump(#3), Linkbelt 8090 Rough Terrain Crane(#3),  CAT 320D Hydraulic Excavator(#1), CAT 305.5E2 CR Mini Hydraulic Excavator(#2), Bobcat Compact Track Loader(#3), Telehandler(#4), CAT CP44 Vibratory Soil Compactor(#2), Articulating Boom Lift(#3) etc.

 

CONSTRUCTION ACTIVITIES: 

  • Underground Garage :

  1. North End: Sub-grade concrete pour;

  2. North End: Retaining Wall construction (Waterproofing);

  3. South End: Level 0 Ramp construction (RCC columns);

  4. South End: Level 1 Slab concrete pour until construction joint 1 (Post-tensioned RCC slab);

  5. South End: Level 1 Slab formwork & rebar assembly (Post-tensioned RCC slab);

  6. East End: Level 1 Elevator Shaft formwork (RCC Shear wall)

 

  • Jubel Hall :

  1. North End: Level 4 slab formwork assembly;

  2. South End: Level 3 RCC Wall construction;

  3. West End: Delivery and shifting of #3 silos of Specmix Mortar.

 

  • Plastic sheeting is laid on the finished concrete surface to protect concrete from sudden rain showers and avoid damage due to pop-outs and scaling/flaking. 2 common labors/sprayers can also be observed applying curing compounds and surface evaporative control chemicals.

  • All labors are found to be wearing PPE and Fall arrestors. Safety Standards for Signs, Signals, Barricades, Trenching, Excavation are observed to be complied with. Also, regularly spaced 20 and 40 Yard waste dumpsters highlight the attention to housekeeping and waste segregation. Safety toolbox meetings were observed and it can be deduced that all construction activities are undertaken in strict compliance with OHSA guidelines. 

  • An elaborate traffic diversion plan, as well as the deployment of flaggers along the entrance and exits of the construction perimeter, highlight the attention towards traffic management and minimizing disruption to the university operations.

 

MANPOWER COUNT: At least 42 labors across Rebar, Concrete, Carpentry (Formwork), Earthwork and Common labor trades were observed to be working on site.

 

CONSTRUCTION MATERIALS: A615 Grade 60 Rebar, Concrete, Engineered Fill, Excavated earth, Waterproofing membrane, System Formwork (Wall panels, struts, H beams, Plywood, Table Forms, Props etc), Post Tension tendons/cable, Geotextile, Vapor barrier, Plastic tarpaulin, curing compound, surface evaporative control compound, PVC conduits, Electrical Gang box etc.
