Located at the corner of Euclid Street and Gregory Drive, the Student Dining and Residential Programs (SDRP) building provides an exciting new space for residents to dine, gather, and find the resources they need. The SDRP is connected to Nugent Hall, University Housing's first new residence hall in more than 40 years. Both Nugent Hall and the SDRP have been recognized with LEED Silver Certification for sustainable building practices.

In the beginning of this project, the contractors  came up with a construction "plan" to accomplish the project by 2010. The following was their timeline:

These dates were subject to changes based on weather or other unanticipated conditions. In the beginning of the project, proper Winter Weather Program was developed and for each bid package (smaller parts of the project) descriptions on how weather impacts delays will be managed were put in place. See below for examples:

  • Bid Package #1 – The General Work Contractor shall provide all enclosures, protection, maintenance, heaters, hoses, dehumidifiers, fuel, etc. to complete all Glazing, Fire Proofing, and Roofing including all required removals. 

Glazing Operations will start in early April and should not be an issue since this work will revolve primarily around the installation of the mullion framing, etc.

Fireproofing and Roofing Operations will be this Bid Package’s prime focus this winter season.  More specifically, Williams Brothers will have to provide a heated enclosure at the north side fire hydrant, as necessary, to feed water to the fireproofing process.  The hoses will be disconnected each night and stored in a warm location to avoid freezing.  The extent of enclosure and protection is still somewhat unknown as of this date. 

In order to minimize extent, we have started Fireproofing Operations sooner and plan to start Roofing Operations within the next week (approximately 6-weeks earlier for each operation).  Additionally, overtime hours will be expended to try to minimize the winter weather impact. 

While starting earlier and working overtime gets these operations closer to completion, these two activities are still vulnerable to winter weather impact.  While it is likely that Fireproofing Completion will only be a minor impact, Roofing Operations will be ongoing well into March 2009.  Roofing will start by working east-west and should be far enough along that heated enclosures will primarily occur at the south side semi-circle --- refer to Sketches “A”, “B”, “C”, and “D” for details.  Heating will be via propane fueled heaters and will likely be 800,000 and/or 1 million BTU forced air type heaters.  The enclosure make-up will be of visqueen panels and draped insulated concrete blankets between the second floor and the underside of the roof of concern.  The appropriate fire extinguishers and monitoring have also been bought through this Bid Package.  In addition, Roofing was bought to work through the winter season, but by starting early we hope to allow more opportunity to pick-n-choose working through the extreme colder temperatures.

If supplemental temporary enclosures are deemed necessary, then there is an approximate $N allowance that can be used within this Bid Package.  Specific extent and use of this allowance for temporary enclosures will be dependent on project schedule.

Lastly, this Contractor is responsible for snow removal of the SDRP project site.

  • Bid Package #2 – The Concrete Contractor shall provide all enclosures, protection, maintenance, heaters, hoses, dehumidifiers, fuel, etc. to complete all Concrete Work including all required removals. This Contractor is responsible for any winter concrete chemicals, heaters, and related visqueen/blanket protection.  This Contractor may have to protect various types of concrete structures [i.e.: southern supported deck, stairway pan in-fills, and loading dock pavement] depending on the timing of cold weather temperatures during this winter season.  The extent of this protection should be minimal and localized to the stairway pan in-fills.  At these locations, CONTRACTOR"A" will build an enclosure envelope at the underside of the stair risers with heat within.  If needed, either potbelly or forced air type heaters fueled by propane will be utilized depending on amount of heated space required.  As with the General Trades Bid Package, the appropriate fire extinguishers and monitoring have been bought through this Bid Package. 

It should be known that ALL slab-on-grade areas have at least 18-inches of granular material (beneath the concrete slab sections) so as to help prevent the susceptibility of frost heave during this winter season since the building will not be heated.

Site concrete work is not scheduled to start until mid-Summer and will be unaffected by this winter weather season.

Besides concrete work, this Bid Package is responsible for aggregate roadways and platforms. CONTRACTOR"A" plans to install ALL of their aggregate roadway and platform requirements within the next four (4) weeks. 

Lastly, this Contractor is responsible for snow removal of the SDRP project site as it relates to main road and sidewalk access ways [i.e.: north sidewalk along Gregory Drive, Euclid Street, and south side perimeter of Building Footprint].

Despite the very excellent management of the contractors, Champaign-Urbana experienced an unusually cold and wet summer and winter season both in 2008 and 2009. As a result, the project got behind schedule. Obviously for projects like SDRP, there is a timeline for construction and this timeline needs to be met to make sure the project will be constructed on time to open the facility for offering dinning to students, staff, and the faculty.  In construction, we typically allocate "certain" number of weather impact days to "anticipate" these delays in the projects. In the case of SDRP, let's assume (hypothetical) that the contractor only allocated 30 days for weather impact days. Unfortunately the jobsite experienced "81" weather impact days (rain, snow, high wind, ligthning, and cold temperatures (below 10) are all weather impact days. As a result, let's assume that the contractor has to pay a penalty of $20K per each delay day at the end of the project.

Dear xxxx,

Please be informed that Critical Path hardscape sitework was directly impacted by heavy rainfall and lightning conditions on the morning of August 28th, 2009. The project experienced a total of 4.25-inches of rainfall over two (2) intense rain storms [the first downpour was estimated at approx. 3-inches and the second downpour was approx. 1.25-inches within short periods of time]. These weather conditions saturated the earth and aggregate base, which prevented “critical path” hardscape sitework from occurring as planned. Lost time for this notice is 1-day.

As discussed during our walk-through of the project site that Friday morning (August 28th, 2009), there was not that much damage, but there was concern for the following: flooding at the Link Entrance as far south as into the eastern RH Stairway; overflow of storm water up to the RH’s NW canopy, but not into the building; storm water accumulation at the SDRP Loading Dock; slight signs of groundwater seepage between the basement wall/basement S.O.G. interface near the Link Entrance at both RH and SDRP buildings and near the NW Canopy at the RH building; storm water scour along the curbline of Gregory Drive due to curb line overflow; storm water accumulation at the western third of the Trailer Compound area; and storm water accumulation at Gregory Drive’s Service Drive. It should be noted that the perimeter foundation drain pumps at both buildings worked hard until late Saturday afternoon (August 29th, 2009).

As directed by the University of Illinois-F & S, xxxx Construction has authorized CONTRACTOR "A" to build a temporary dam at the walkway ramp nearest the Link Entrance; encouraged CONTRACTOR B  to help quicken clarification to the speed bump RFP at the SDRP Loading Dock; and requested that the CONTRACTOR B’s temporary dam plan be completed along Gregory Drive. This flooding event is a fresh reminder that the drainage issue along Gregory Drive still needs to be resolved.

Weather Tracking Summary:
Lost Time for this Notice 1 - day
Lost Time for Previous Notice 70 ½ - days
Lost Time to Date 80 ½ - days

The overall effect on the project schedule has not been determined, but XXX Construction will continue to monitor for future remediation. Should you have any questions, please contact me immediately.

We have collected Atmospheric Data for the State of Illinois from 1989 to 2014 including the following
  • Hourly Average Air Temperature - hourly average air temperature for each site.
  • Daily Maximum and Minimum Air Temperatures - warmest and coldest temperatures recorded at each site each day.
  • Daily Average Wind Direction - average wind direction for each site for each day.
  • Daily Average Wind Speed - average wind speed for each site for each day.
  • Daily Maximum Wind Gust - highest recorded wind gust at each site for each day.
  • Daily Precipitation - daily total of precipitation at each site.
  • Solar Radiation - daily total of solar radiation at each site.
  • Potential Evapotranspiration
  • Daily Average Dew Point

Data: https://uofi.box.com/s/7c1d10kczr7w63k28zqz  (20 txt files, one per data collection site, that need to be parsed in based on the above description; password: to be introduced in class). 

We would like to perform (K-means?) clustering on this data using all data fields and see if we can categories the observations into groups of normal, possible weather impact days, impact days, and sever weather impact days. Such analysis will be beneficial to predict and manage weather impact days and the damages it may cause the completion date of a project (imagine school to start in August without the dining hall project being complete, leaving thousands of students with no meal throughout the day!!). Once the assessment using clustering is conducted, let's visualize the outcome to see if we can see certain patterns in the data (for the purpose of visualization, let's only use the Daily Precipitation, Daily Minimum Air Temperature, and Daily Maximum Wind Gust as the only 3 parameters for clustering). Plot the outcome and discuss how this could have been anticipated during 2008 to 2010 based on historical data before 2008. Provide any recommendation for best prediction of weather impact days for future construction projects.
