Overview

Bruce Street Pump Station Relocation Section: 00 20 00 T04.2021 Page 1 Overview February 2021

2017

OVERVIEW This document is a Supplementary Specification to the Standard Specification for Municipal Services, developed by the Nova Scotia Roadbuilders - Consulting Engineers of Nova Scotia Joint Committee on Contract Documents. The Halifax Regional Water Commission (Halifax Water), in response to a need to standardize their specification practices, reduce review and approval time, and regulate the specifications produced by their consultants, have adopted the Standard Specification for Municipal Services. As an active member on the Joint Committee during the Standard Specification’s development, Halifax Water became familiar with, and contributed input to, the Standard Specification’s development. Whereas the Standard Specification is intended for both sewer and water projects throughout the province of Nova Scotia, Halifax Water’s concern is limited to water and wastewater systems within the limits of the Halifax Regional Municipality, additional specification requirements will be provided as supplementary specifications. These project documents have been prepared for use with and require being read in conjunction with the 2020 updated version of The Standard Specifications for Municipal Services as published by the Nova Scotia Roadbuilders – Consulting Engineers of Nova Scotia Joint Committee on Contract Documents. Copies of The Standard Specification for Municipal Services are available from:

1.0 INTRODUCTION We have conducted a geotechnical investigation for the proposed Pump Station at 9 Bruce Street in Dartmouth, Nova Scotia, at the request of CBCL Limited. The purpose of this investigation was to evaluate the subsurface conditions at the site and to provide recommendations. This report presents all of our findings and our geotechnical recommendations for design and general site work. 2.0 SITE DESCRIPTION AND GEOLOGY

The proposed pump station is located at 9 Bruce Street in Dartmouth, NS, and includes a wet well, a valve chamber, an asphalt paved parking area, and a concrete control panel mounting structure. The site is grass covered and bordered by an asphalt paved parking area to the south (599 Portland Street), Bruce Street to the east, and a residential building to the northwest. The site has a slight upward gradient to the road starting roughly 4 m from the curb. Farther away from the curb, the site is generally flat. Photograph A show a view of the site from the south. Based on geologic mapping, the native site soil appears to consist of a veneer of Beaver River Till, which is a diamicton with a sandy matrix and locally derived clasts. Bedrock in the area is mapped as either part of the Beaverbank Formation or Taylors Head Formation, both of which are part of the Goldenville Group. The Beaverbank Formation generally consists of metasiltstone to slate with very thin to thin beds of metasandstone. The Taylors Head Formation generally consists of metasandstone locally interlayered with cleaved metasiltstone and rare black slate.

3.0 SUMMARIZED SUBSURFACE CONDITIONS

The field program consisted of one (1) borehole completed on May 25, 2020. The borehole location is shown in Drawing 1 in the appendix. The borehole was conducted using a tracked drill rig. Representative samples were taken during the field work and the conditions at the borehole were logged in detail. The soil conditions encountered at the site are described in detail on the appended Borehole Record and summarized below in the following paragraphs and Tables A and B. The subsurface conditions encountered throughout the site consist of a surficial organic layer overlying fill, and then glacial till. The surficial organic layer was observed to be 75 mm thick. The fill was 1.4 m thick. Glacial till was encountered at a depth of 1.5 m and groundwater was observed at a depth of 2.6 m. The borehole was advanced to a depth of 9.1 m. Bedrock was not encountered. The fill and glacial till both generally consist of silty gravel with sand (GM). The fill was in a compact state and the till was in a dense to very dense state. A sieve analysis was conducted on one (1) sample of the fill and showed 42.6% gravel, 41.0% sand, and 16.4% fines (silt and clay). The grain size curve is attached in the appendix. Moisture content testing was conducted on four (4) samples of the onsite soils. Testing showed moisture contents between 5.7% and 7.0%. Results are shown below in Table B.

4.0 DISCUSSION AND RECOMMENDATIONS From our correspondence, we understand that a new pump station consisting of a wet well, a valve chamber, an asphalt paved parking area, and a concrete control panel mounting structure is proposed. Furthermore, we understand that the wet well will likely have a 3.0 m diameter base and be founded 4.0 m below grade, and that the valve chamber will likely have a 3.0 m by 3.5 m base and be founded 2.5 m below grade. We are currently unsure of the final grades; however, we expect that some fill will be used to bring the site up to the elevation of the road. Based on the subsurface conditions encountered, the following recommendations are provided for the project. 4.1 Earthworks Earthworks for this project will mainly involve excavations into the existing soils and placement of structural fill to achieve design grade elevations, as required. 4.1.1 Excavation Based on our understanding of the conceptual depths of the proposed structures, excavations into fill and glacial till will be required for this project. Within the wet well, valve chamber and concrete control panel mounting structure, the existing fill should be removed and reinstated with structural fill, as required. Based on the conceptual depths of the proposed wet well and valve chamber, it is unlikely that fill will be encountered at the base of these structures. Due to the groundwater level observed, a 300 mm thick layer of imported granular material, such as DTIR Type 1 Gravel, is recommended below the wet well and valve chamber. In the proposed paved areas, the surficial organic layer should be removed. The subgrade should be proof-rolled with a static 10 tonne steel drum roller and any excessively weak or soft zones should be replaced with structural fill. Temporary excavated side slopes should be stable at one horizontal to one vertical (1H:1V). Depending on the proximity of the structures to the roadway, a trench box (or other means of shoring) may be required to prevent excavations from encroaching into the roadway. Safe excavated side slopes are the responsibility of the contractor. 4.1.2 Dewatering of Excavations The contractor undertaking the earthworks must be prepared to dewater excavations. Excavations should remain free of standing water. Concrete and backfill should not be placed in standing water, slough, or over softened bearing soils.


Page 5

Discharge from the dewatering activities must be carried out in strict accordance with environmental regulations. 4.1.3 Structural Fill Placement and Compaction Structural fill required for the site should consist of the following:

approved on-site soils, imported, quarried rockfill and gravel, or; sand and gravel pit run.

We recommend backfilling the structures with a granular, non-frost susceptible material, such as DTIR Type 2 Gravel. Reuse of the on-site soils for general grading may be permissible; however, overly wet material and oversized material (large cobbles and boulders) would have to be sorted out. Drying of any overly wet material could be considered, but will be dependent on weather. Approved on-site soils planned for reuse should be placed directly in the intended areas or compacted in stockpiles for later use. Excavated on-site soils containing organics will not be suitable for reuse. Structural fill should be placed at or near the optimum moisture content (ASTM D698). The lift thickness used during placement of fills must be compatible with the compaction equipment and the material type to ensure the specified density throughout. For preliminary consideration, the lift thickness should not exceed approximately 300 mm for mass filling and 200 mm for backfilling of structures and services. The maximum particle size should be no larger than ⅔ of the lift thickness. Light weight compaction equipment should be used within 1.0 m of the walls of the structures. Structural fill materials should be compacted to the following percentage of maximum Standard Proctor dry density:

Fill below wet well, valve chamber, and control panel mounting structure 100% Fill within 300 mm of paved area subgrade 98% Fill below 300 mm of paved area subgrade 95%

Where fill is needed below the wet well, valve chamber, or concrete control panel mounting structure, the fill must be extended laterally beyond the edges of the structures to include a 300 mm bench and the conventional 1H:1V splay. 4.1.4 Slopes and Toe Drainage Permanent structural fill slopes should be 2H:1V, or lower. Based on the information provided, we do not expect any permanent cut slopes for the project. If any are required, we should be notified to review our recommendations.


Page 6

4.1.5 Subgrade (Wet Well, Valve Chamber, Control Panel Mounting Structure, and Parking Area) The contractor must take precautions to avoid disturbance of the site soils, or reinstate the material to the required condition. The condition of the subgrade should be reviewed prior to placement of base gravels. The parking area subgrade should be shaped to shed water. 4.1.6 Winter Construction Additional effort will be required to conduct earthwork during winter conditions. Winter construction guidelines are attached in Appendix B Undertaking earthworks in the winter is not ideal and despite best efforts and good intentions, the quality of earthworks often is compromised. 4.1.7 Inspection and Testing It is recommended that inspection of all footing bearing surfaces be conducted by experienced geotechnical personnel prior to placement of concrete. Inspection and testing is also recommended during site grading and backfilling operations. 4.2 Foundations 4.2.1 Wet Well and Valve Chamber As mentioned in Section 4.1, we recommend a 300 mm thick layer of imported granular material, such as DTIR Type 1 Gravel, below the structures. It is anticipated that the net bearing pressure of the wet well and valve chamber will be less than the existing in-situ vertical effective stress; therefore, adequate bearing resistance should be available. Settlement will be proportional to the total applied weight of the structure and surrounding fill (if required). We can review once a design weight is available; however, post construction settlement will likely be less than 25 mm based on the subsurface conditions encountered. A minimum soil cover of 1.2 m is required for frost protection. Based on the conceptual depths of the structures, this should be achieved. The structures should be designed to resist buoyant forces. 4.2.2 Concrete Control Panel Mounting Structure A 150 mm thick layer of DTIR Type 1 Gravel is recommended below the pad for levelling and support purposes. The gravel should be compacted to 100% Standard Proctor. A modulus of subgrade reaction, k, of 50 MPa/m may be used for the slab design. This modulus corresponds to a 300 mm x 300 mm square bearing plate.


Page 7

We typically recommend a 50 mm thickness of approved insulation for frost protection of exterior slabs but this may vary depending on subgrade type and slab thickness and should be reviewed once more details are known. The insulation should extend 1 m beyond the slab edge. 4.3 Pavement Structure

Adequate drainage (subsurface and/or ditching) should be in place to remove water from within the pavement structure. The drainage system should be such that the pavement structure remains adequately drained. Lack of drainage will cause premature deterioration of the asphalt pavement.

With the subgrade prepared as outlined in Section 4.1, the following pavement structure is recommended for low volumes of light vehicles. However, it will be critical to evaluate the subgrade prior to placement of gravel. Table C: Pavement Structure Thicknesses Material Standard Duty Pavement1 Asphalt Concrete: Top Course (C Mix) Base Course (B Mix)

75 mm -

Type 1 Gravel 150 mm Type 2 Gravel 150 mm Notes: 1Cars and light trucks.

All aggregate and asphalt concrete materials should meet the DTIR Standard Specifications. The gravels should be compacted to 100% of Standard Proctor maximum dry density. Asphalt concrete should be compacted to 92.5% of Maximum Theoretical Relative Density. 4.4 Seismic Classification The site classification for seismic site response was based on our geotechnical investigation. The recommended site classification for seismic site response, as per Table 4.1.8.4.A of NBCC 2015 is Site Class D. 4.5 Additional Geotechnical Services It is recommended that inspection of the bearing surfaces be conducted by Conquest Engineering prior to placement of concrete. Inspection and testing also is recommended during site grading and backfilling operations.

Rock Quality Designation (RQD)

The classification is based on a modified core recovery percentage in which all pieces of sound core over 100 mm

long are counted as recovery. The smaller pieces are considered to be due to close shearing, jointing, faulting, or

weathering in the rock mass and are not counted. RQD was originally intended to be done on N-size (45 mm) core;

however, it can be used on different core sizes if the bulk of the fractures caused by drilling stresses are easily

distinguishable from in situ fractures.

RQD ROCK QUALITY

90 – 100 Excellent, intact, very sound

75 – 90 Good, massive, moderately jointed or sound

GEOTECHNICAL RECOMMENDATIONS

WINTER CONSTRUCTION

The following are general geotechnical recommendations for earthworks for building areas in winter

conditions.

General

Earthworks conducted during freezing conditions are suspect. Special procedures and

precautions must be exercised to minimize the risk of future problems.

A site meeting should be held at project start-up to discuss the schedules of the various

contractors in relation to the following geotechnical recommendations.

Excavation

The rootmat/topsoil layer and any overlying snow will reduce the frost penetration. Conducting

only the excavation work required for each day of work is recommended to minimize freezing of

the soil in the foundation areas.

Excavated material to be used as structural fill should not be stockpiled, but should be placed and

compacted immediately after excavation.

Fill Placement

Based on our experience, it is generally impractical to place well-graded gravel, sand, or fine-grained

soils in temperatures lower than about -5 degrees Celsius. On very cold days, loose material starts to

freeze within about 15 minutes. At temperatures below -5 degrees Celsius, clear gravel or clear rockfill

is recommended but subject to design considerations governing the work.

The following provides recommendations for all structural fill types.

Structural fill placement should be conducted in small areas. Depending on the temperature, this

may allow for continuous placement of fill lifts during the work day without the requirement for

excavation of frozen material prior to placement of the next lift.

Material containing snow or ice should not be incorporated in the work. During snow events, fill

placement should be stopped. When the earthwork restart, all snow and ice should be removed

from the fill surface prior to subsequent fill placement. In order to remove all snow and/or ice

after a snow event, some of the underlying fill may have to be removed and wasted.

For intermediate fill lifts, frost protection (e.g.; straw, insulated tarp, etc) should be provided at

the end of the work day, or alternatively, fill that freezes overnight should be removed in the

morning. Also, any snow or ice should also be removed. Fill surfaces should be sloped to

prevent ponding of water during milder weather.

of 2

The final fill surface, the base of footing excavations and slab subgrade should be protected from

freezing. If the final fill surface is exposed to freezing temperatures, heat will be required to

thaw the soil. Test pits and temperature readings could be completed to determine if the soil is

above freezing. Consideration should also be given to the installation of thermocouples in the

fill during placement, as a means of reading temperatures at depth. The areas that were frozen

should be proof-rolled.

The moisture content of fill materials should be approximately 2% below optimum. Fill

materials with moisture contents above the optimum should not be used.

Loose edges of the structural fill lifts should be avoided to reduce frost penetration. Edges of fill

lifts should be tapered and compacted.

Regular checks of the temperature of the fill should be made. The soil temperature should be

greater than +2C to allow for compaction to the specified degree.

Footing Construction

Footings should not be placed on frozen material.

Where the footing elevation is within approved finer-grained materials, we recommend over-

excavation by at least 6 inches and placement of nominal 1 inch stone or other clean gravel. This

will reduce disturbance of the bearing surface.

Following construction of footings, temporary frost protection must be provided to avoid

freezing of the bearing surface and for protection of the concrete during curing.

Consideration should be given to specifying that the footing depth for interior foundations be

1.2 m below slab subgrade for frost protection during construction; or alternatively, fill could be

temporary bermed over interior footings to provide insulation.

Foundations should be backfilled with a free-draining granular material and drainage provided to

prevent adfreeze of foundations, particularly during construction.

Cast-in-place concrete should be protected during colder weather conditions as per CSA A23.1-

2014.

Geotechnical Inspection and Testing

The information herein should be reviewed by geotechnical personnel and customized to the specific

geotechnical aspects and design considerations of a site. Full-time inspection and testing by experience

geotechnical personnel is particularly important during earthworks in winter conditions and is strongly

recommended.
