5.3 General Recommendations
5.3.6 Winter Construction Considerations
Placing frozen fill or engineered fill on frozen subgrade is not recommended. If work is to be undertaken during freezing conditions, care should be taken to heat and/or insulate the fill prior to and after placement to keep it from freezing. Some typical measures include heated box trucks, insulated tarps, or bales of hay. Frozen subgrade soil and/or previously placed fill must be thawed or removed prior to placement of any engineered fill.
Cast-in-place concrete should be protected during colder weather conditions as per CSA A23.1.

6 Closure
This report has been prepared to assist in the design and construction of the proposed replacement of the West River #1 Bridge (ANT 013) in Antigonish County, Nova Scotia. If any uncommon details are included in the final design of the proposed structure the geotechnical engineer should be consulted. Similarly, if conditions different from those detailed on the borehole records are noted during construction, the engineer should be notified to allow reassessment of any design assumptions, if necessary.

Soil Description
Behavioral properties (i.e., plasticity, permeability) take precedence over particle gradation in describing soils.
Terminology Describing Soil Structure
Desiccated Having visible signs of weathering by oxidation of clay minerals, Fissured Having cracks and, hence, a blocky structure
Varved Composed of regular alternating layers of silt and clay
Stratified Composed of alternating layers of different soil type, e.g., silt and sand Well Graded Having wide range in grain size and substantial amounts of all
Uniformly Graded Predominantly of one grain size
Terminology used for describing soil strata based upon the proportion of individual particle sizes present:
Trace, or occasional Less than 10%
Some 10–20%
Adjective (e.g., silty or sandy) 20–35%
And (e.g., silt and sand) 35–50%
The standard terminology to describe cohesionless soils includes the relative density, as determined by laboratory test or by the Standard Penetration Test “N”-value: the number of blows of 140 pound (64 kg) hammer falling 30 inches (760 mm), required to drive a 2-inch (50.8 mm) O.D.
splitspoon sampler one foot (305 mm) into the soil.
Relative Density “N” Value Relative Density %
Very Loose <4 <15
Loose 4–10 15–35
Compact 10–30 35–65
Dense 30–50 65–85
Very Dense 50 >85
The standard terminology to describe cohesive soils includes the consistency, which is based on undrained shear strength as measured by in-situ vane tests, penetrometer tests, unconfined compression tests, or occasionally by standard penetration tests.
Undrained Shear Strength
Consistency kips/sq. ft. kPa “N” Value
Very Soft <0.25 <12.5 <2
