ENQUIRIES AND RESPONSES #2 NWIT-21-13

Sapperton 2021 Sewer Separation and Waterworks Program New Westminster, BC

ANSWERS TO SUBMITTED QUESTIONS Q11 Will there be an area available to stage all the spoil considered contaminated while

testing occurs? Piles will need to be made from all trench spoil until testing is completed, so a rough area would be beneficial to calculate accurate truck rounds.

A11 Testing is to take place in situ. On previous project the testing was completed while the contractor was completing pre-locates and test results were available prior to any soil disposal.

Q12 For the watermain located on Richmond and Buchanan, the curb is located in close

proximity to the proposed. Is the contractor expected to allow for full curb restoration? Is there a separate line item for curb restoration?

A12 Refer to Addendum #3 for revised watermain alignment on Buchanan Avenue. Any damaged curb will be replaced as an incidental to other parts of the project on all streets.

Q13 From the City’s experience, can you explain how in-situ testing was completed for contamination testing? To determine contamination classification, samples must be collected and results are received after 5 days unless 24hr testing is requested. Will we be allowed to stockpile the excavated soil for testing?

A13 On previous project the testing was completed while the contractor was completing pre-locates and test results were available prior to any soil disposal. No stock piling was necessary using this method. There is no stock piling area(s) available.

Q14 Can you share what conversion rate the engineer is using to calculate m3 to mT? A14 A factor of 2 metric tonnes per cubic meter has been used to estimate the tonnage for

trench line material disposal. Tenderers should perform their own takeoff and make their own assumptions when calculating. Payment will be based on actual tonnage disposed as per Supplementary Specification 31 23 01 1.10.9S.

Q15 SOQ Richmond Street Item 4.16 – “Removals”, what is this pay item for? A15 Refer to Addendum #3 Revised Appendix 1 – Schedule of Quantities and Prices Revised

June 24. This item has been removed.

NWIT-21-13 – FAQ #2 June 24, 2021 of 3

Document #1866011

Q16 What type of tests must we allow for contamination testing? Hydrocarbons, metals,

PAH? A16 For information only we have attached the Environmental Characterization Report

(GeoWest File: GA20-1041-01) for a 2021 Watermain Project located on adjacent streets. Summary of testing for this project can be found in the report. Contractor to determine what testing will be required based on licensed disposal facility being utilized.

Q17 There are currently critical shortages of PVC pipe products and various watermain pipe and fittings. So much so that the manufacturers cannot provide a solid delivery date for many materials. How will this be handled under the contract relative to schedule?

A17 The successful Tenderer is to make all reasonable efforts to complete the project in the timeline outlined in the IFT. Please provide evidence of prompt ordering of materials after receiving Notice to Proceed and IFC plans. No cost associated with any delay will be consider. Contract time may be extended if proven warranted.

Q18 Is there test hole data available for this project? If so, can it be provided? What about the

soils analysis for contaminants? A18 No test hole data is available for this project.

Q19 Please confirm days are “working” days A19 Yes, days are to be “working days”.

Q20 How will the measurement for payment be administered for disposal of excavated soil?

For example, is the unit for clean material paid in all circumstances and the various levels of contamination paid as a premium or is the unit rate to include the total cost for each type of material?

A20 Payment for disposal of excavated soil will be paid under only one of the items in the schedule of payment items. The payment for the unit rate is to include the total cost for each type of material.

Q21 In areas where single lane alternative traffic poses safety concerns and/or greatly impede the work, will a road closure be granted?

A21 No full road closures are permitted.

Q22 What is the thickness of existing asphalt pavement for each street? A22 Existing asphalt thickness on each street is unknown. Based on previous projects in the

area, asphalt thickness can be expected to be between 50mm and 175mm.

NWIT-21-13 – FAQ #2 June 24, 2021 of 3

Document #1866011

Q23 What is the thickness of pavement restoration or do we match existing? A23 Asphalt restoration for permanent pavement patching to be as per MMCD Standard

Detail Drawing G5. Q24 Regarding the statement in the drawings I-02 to I-06: “All separated STM services

encountered during construction to be connected to proposed storm sewer per MMCD STD. DWG S8. This includes all properties that have been identified as (New Dev.)” If we were to encounter any which item would we use to get paid for this?

A24 Payment for storm sewer services to be made under the “Supply and Install Service Connection” item and when required “Inspection Chamber (MMCD S9)”

Q25 The Keary street section in the tender is miss labelled. A25 Please see revised Schedule of Quantities and Prices.

Q26 The optional work on Richmond, Simpson to Keary, the catch basins and leads seem to

be under the regular items, but the mainline is clearly noted as optional? I understand they are unit rates, but we do spread our bonding, mob, testing and other overhead costing across these items, and it is impossible to back it out of indeterminate items.

A26 All works on Richmond Street shown on S16-0184/I are to be Provisional including the two Catchbasins and leads north of Shiles Street near station 15+160. These items will be paid under the Provisional unit rates if the works proceed.

Project: Braid Street, Eighth Avenue and Lane East of Buchanan Street, New Westminster, BC

Subject: Water Main Upgrades - Environmental Soil Characterization

1 Introduction

In general accordance with our proposal P20-1052-00 dated 12 February 2020, GeoWest Engineering Ltd.

(GeoWest) has prepared this environmental soil characterization report for the proposed water main upgrade

on Braid Street, Eighth Avenue and the Lane east of Buchanan Street in New Westminster. The environmental

soil characterization was carried out concurrently with the geotechnical investigation. The geotechnical

engineering report will be provided under a separate cover. Authorization to proceed with the scope of work

discussed in the proposal was received from the City of New Westminster (the Client) via e-mail on 20 February

2020.

The objective of this soil characterization was to determine soil disposal options prior to the utility upgrades.

This report documents the Subsurface Investigation activities conducted at the Site.

2 Site Description and Setting

The project locations are shown on the attached Figure 1, Appendix A. It is understood that the project will

entail water main upgrades at the following proposed locations:

• Braid Street: E. Columbia to Eighth Avenue (120 m length);

• Eighth Avenue: Braid Street to Lane East of Buchanan Avenue (110m length); and

• Lane East of Buchanan Avenue: Eighth Avenue to Knox Street (290 m length).

Environmental Soil Characterization

Page 2

The surficial sediments at the project alignment locations, as identified by the Geological Survey of Canada1, are

Vashon Drift and Capilano sediments with sub-unit “VC”. Sub-unit “VC” sediments are glacial drift including:

lodgement and minor flow till, lenses and interbeds of sub-stratified glaciofluvial sand to gravel, and lenses and

interbeds of glaciolacustrine laminated stony silt; up to 25 m thick but in most places less than 8 m thick; overlain

by glaciomarine and marine deposits normally less than 3 m thick but in places up to 10 m thick.

3 Scope of Work

The soil sampling activities carried out by GeoWest on the Site were conducted in general accordance with

GeoWest’s Proposal (P20-1052-00) dated 12 February 2020 and consisted of the following:

• Contact BC One Call and review utility information on the City’s on-line mapping system to obtain

information regarding the locations of existing underground services at the project Site. Based on this

information, auger hole locations will be selected at a suitable off-set distance from existing utilities;

• Retain the services of a utility locating contractor to clear the auger hole locations of underground

services prior to drilling;

• Retain the services of a drilling contractor to advance up to ten boreholes with a truck-mounted drill rig

equipped with solid-stem continuous flight augers;

• Collect soil samples from each borehole location at different depths depending upon the encountered

stratigraphy;

• Log the encountered soil stratigraphy at all borehole locations;

• Field screen the soil samples using a photoionization detector (PID);

• Submit soil samples to Caro Analytical in Richmond, BC, which is accredited by Canadian Association for

Laboratory Accreditation (CALA) and follows BC MOE recognized procedures for laboratory analyses;

• Select up to twenty (22) soil samples for laboratory analysis of metals, sodium and chloride; and

• Prepare a Soil Characterization letter report summarizing the Site activities, methodology and results of

the investigation and GeoWest’s conclusions and recommendations for strategies for disposal of

excavated soil (if required) during construction.

4 Applicable Standards

The Site is located in a roadway. As such, the BC CSR Industrial Land Use (IL) soil standards, set out in Schedule

3.1, are applicable. For soil classification/disposal purposes, the BC Hazardous Waste Regulation (HWR)

standards/criteria would also apply to the Site. The Site-specific factors that would apply at the Site are outlined

in Table 1.

• CSR Drinking Water (DW)

Excavated soil not suitable for use as trench back fill (from a geotechnical perspective) will be removed from the

Site. As such, the soil analytical results were compared to the BC CSR Schedule 3.1 standards for agricultural

land use (AL), residential low-density land use (RLLD), residential high-density land use (RDHD), commercial land

use (CL) and industrial land use (IL) to assess options for offsite disposal.

5 Methodology and Procedures

GeoWest will conduct a BC One Call and Site-specific JSA prior to the field program. A private utility locator will

complete an EM survey prior to drilling activities. Drillers will use a truck mounted drill rig to advance boreholes

to a maximum depth of 1.5m below ground surface (bgs).

GeoWest will log the soil stratigraphy, field screen and collect soil samples for laboratory analysis.

The soil analytical results from the Subsurface Investigation will be tabulated and compared to the CSR AL, RLLD,

RLHD, CL and IL soil standards, CSR DW and AW standards. GeoWest will prepare a Subsurface Investigation

report summarizing the Site activities, methodology, and results of the investigation to issue to the Client.

5.1 Field and Laboratory QA/QC

To provide confidence in the field data collected from the Site, a Quality Control/Quality Assurance (QA/QC)

component was included in the sampling program. The field QA/QC component is summarized below. CARO

Analytical Services (CARO) from Richmond, BC, was selected for the analyses of the soil samples. CARO has their

own internal QA/QC program, which is also briefly summarized below.

Table 2: Field and Laboratory QA/QC

Field QA/QC

Field equipment are cleaned, calibrated, and maintained in good working condition.

Common equipment is cleaned in the field, between each sampling location. New

powder-free nitrile gloves are used for each sample collected. All tools are cleaned

between samples. All sample containers are provided by the laboratory which are clean

and sterile and are appropriate for the parameters analyzed. All sample containers are

labelled with the consultant’s name (i.e., GeoWest), their respective sampling location

identification, date, and project reference number. Samples are kept cool by storing and

transporting them in a laboratory-supplied cooler with ice packs. Chain-of-custody

protocol is followed for submission of samples.

Laboratory QA/QC

CARO routinely analyses laboratory replicates, standard reference materials and method

blanks as part of its internal QA/QC program. CARO also determines surrogate spike

recoveries (for volatiles and polycyclic aromatic hydrocarbons). Analytical results are

compared to internal data quality objectives and results not meeting their internal

QA/QC criteria are flagged. The laboratory results are reviewed by the chief chemist and

results are released when the data meets the internal data quality objectives.

6 Field Observations

6.1 Fieldwork Schedule

The following is a summary of the fieldwork schedule for the Subsurface Investigation:

• 24 March 2020 - Utility locate

• 26 March 2020 – Drilling and soil sampling

6.2 Soil Stratigraphy Observations and Sampling

On 26 March 2020, Blue Max Drilling Ltd. mobilized from Surrey, BC with a truck mounted drill rig for the

environmental investigation. During drilling, the solid stem auger flights were advanced in approximately 1.5 m

lengths to allow for sampling and visual logging of soil conditions. Soil logging was conducted by visually

observing soil conditions from the auger flights. Due to limited access within the laneway east of Buchanan

between Cedar Street and Eighth Avenue, a portable track mounted Ditch Witch equipped with solid stem auger

flights was utilized.

Nine boreholes (two within the Braid Street segment, two within the Eighth Avenue segment and five within

the lane east of Buchanan Street) were advanced to a maximum depth of 3.1 m bgs. A total of 28 discrete soil

samples were collected for this investigation.

Ms. Lisa Oswald, AScT, of GeoWest was present on 26 March 2020 to oversee the field program and collect soil

samples. Soil samples were collected and immediately transferred into laboratory-supplied, pre-cleaned jars.

Indelible markers were used for marking the lids and jars with the appropriate sample identification number or

reference. GeoWest’s field scientist wore new nitrile powder-free gloves prior to collecting each soil sample.

Soil samples were transferred into plastic bags and allowed to equilibrate with the ambient temperature for

approximately 10 minutes prior to measuring soil-gas headspace concentrations in the plastic bags using an RKI

Eagle2™ PID. Headspace vapour readings for soil samples are recorded in the following table. Soil samples were

submitted to CARO Analytical Services (CARO) in Richmond, BC.

The PID measurements from the soil samples collected from the auger holes were not detectable. No staining

or hydrocarbon impacted odorous soils were noted by visual or olfactory observation during the logging of the

soil at the boreholes. The vapour concentrations recorded at the Site are considered to be low and are not an

indicator of petroleum hydrocarbon contamination.

Considerations for selecting soil samples for analyses at select boreholes included soil stratigraphy observations.

In general, the soil profile encountered in the boreholes consisted of approximately 38 to 200mm of asphalt

underlain by sand and gravel road base, underlain by fill generally comprised of loose to compact silty sand or

sand and gravel with varying silt content. Borehole 20-AH3 was located on an unpaved area and encountered

about 75 mm of 19 mm crushed sand and gravel fill at the surface.

The native soils at the generally varied from sandy silt with varying gravel content and trace to some clay to

clayey silt with some sand and trace gravel to silty sand and gravel. At several of the boreholes the native soils

were noted to contain cobbles and were till-like at depth.

Groundwater was not observed in any of the during the drilling investigation; however, the loose to compact

silt and sand at 20-AH7 @ 2.1m was noted to be wet.

Detailed soil logs for the boreholes are included in Appendix B. The Site Location Plan (Figure 1) and Auger Hole

Location Plan (Figure 2) are presented in Appendix A.

7 Soil Analytical Results

Selected soil samples collected on 26 March 2020 were submitted for one or more of the following parameters:

metals and sodium and chloride ions by saturated paste.

The analytical results found metals concentrations in all submitted soil samples were either less than the RDL or

below the applied CSR AL, RL(LD), RL(HD), CL and IL standards with the exception of arsenic (10.6 µg/g) at 20-AH4

@ 1.8m and cadmium (1.31 µg/g) and zinc (494 µg/g) at 20-AH3 @ 0.3m. These parameters were found to

exceed the CSR AL, RL(LD), RL(HD), CL and IL standards. The concentration of lead (161 µg/g) at 20-AH3 @ 0.3m

also exceeded the CSR CL standard (150 µg/g) for intake of contaminated soil.

The concentrations of sodium and chloride ions in soil were greater than the CSR RL(HD), CL and the applicable IL

standards in the samples collected from the following locations:

The above noted exceedances are shown on the attached Figure 2 included in Appendix A. Tabulated results of

the soil analyses are included in Appendix C. Appendix D contains the Chain-of-Custody forms and Laboratory

Certificates, for the analytical data obtained from CARO.

8 Results of the QA/QC Program

GeoWest also reviewed the laboratory QA/QC data provided by CARO in the laboratory certificates. The

laboratory certificates included results for laboratory blanks, replicates and reference samples. They also

included results of the laboratory’s calibration check.

The QA/QC results are within the allowable range of laboratory acceptance; therefore, the data is deemed

reliable.

The results of laboratory’s internal QA/QC samples are included in each of the attached laboratory certificates

included in Appendix D.

9 Conclusions and Recommendations

GeoWest was retained to conduct a Subsurface Investigation for due diligence purposes for the City of New

Westminster to characterize the soil conditions prior to the proposed water main upgrade.

The Subsurface Investigation included soil sampling from nine boreholes (two within the Braid Street segment,

two within the Eighth Avenue segment and five within the Lane east of Buchanan Street) advanced to a

maximum depth of 3.1 m bgs. The analytical results of the soil samples collected revealed the metals, sodium

and/or chloride ion concentrations were found to exceed the CSR IL standards at the following locations:

• Lane east of Buchanan Street between Knox Street and Cedar Street (20-AH1 @ 0.3m, 20-AH2 @ 0.3m

and 1.2m and 20-AH3 @ 0.3m). The soil at 20-AH3 @ 0.3m also exceeded the CSR IL standards for

cadmium and zinc;

• Eighth Avenue heading southwest from 467 Eighth Avenue (20-AH4 @ 0.9m and 1.8m. The soil at 20-

AH4 @ 1.8m also exceeded the CSR IL standard for arsenic; and

• Braid Street, near the intersection of Columbia Street and the westbound bus stop, west of Columbia

Street (20-AH6 @ 0.3m and 1.2m).

Based on the results of the Subsurface Investigation, if the excavated soil from the watermain improvements at

these locations cannot be utilized as backfill, it must be removed for offsite disposal at a facility permitted to

accept CSR CL+/IL+ soil.

10 Closure

No environmental site assessment or investigation can wholly eliminate uncertainty regarding the potential for

recognized environmental conditions in connection with a site. Performance of a standardized preliminary site

investigation protocol is intended to reduce, but not eliminate, uncertainty regarding the potential for

recognized environmental conditions in connection with the Site, given reasonable limits of time and cost.

GeoWest Engineering Ltd. (GeoWest) has prepared this letter report exclusively for the City of New Westminster

and is intended to provide an assessment for potential presence of contamination at the Site. The conclusions

made in this report reflect GeoWest’s best judgement in light of the information available at the time of writing

this report. No other warranty, expressed or implied, is made. Any use which a third party makes of this report,

or any reliance on or decisions to be made or actions based on this report, are the responsibility of such third

parties. GeoWest accepts no responsibility for damages, if any, suffered by a third party as a result of decisions

made or actions based on this report. The standard limitations of this report are specified in Appendix E.

Big Picture Sidekicks

You know that the sample you collected after

snowshoeing to site, digging 5 meters, and

racing to get it on a plane so you can submit it

to the lab for time sensitive results needed to

make important and expensive decisions

(whew) is VERY important. We know that too.

We've Got Chemistry

It�s simple. We figure the more you

enjoy working with our fun and

engaged team members; the more

likely you are to give us continued

opportunities to support you.

Ahead of the Curve

T h r o u g h r e s e a r c h , r e g u l a t i o n

knowledge, and instrumentation, we

are your analytical centre for the

technica l knowledge you need,

BEFORE you need it, so you can stay

up to date and in the know.

APPENDIX 2: QUALITY CONTROL RESULTS


WORK ORDER 0032275

The following section displays the quality control (QC) data that is associated with your sample data. Groups of samples are prepared

in �batches� and analyzed in conjunction with QC samples that ensure your data is of the highest quality. Common QC types include:

� Method Blank (Blk): A blank sample that undergoes sample processing identical to that carried out for the test samples. Method

blank results are used to assess contamination from the laboratory environment and reagents.

� Duplicate (Dup): An additional or second portion of a randomly selected sample in the analytical run carried through the entire

analytical process. Duplicates provide a measure of the analytical method's precision (reproducibility).

� Blank Spike (BS): A sample of known concentration which undergoes processing identical to that carried out for test samples, a l so

referred to as a laboratory control sample (LCS). Blank spikes provide a measure of the analytical method's accuracy.

� Matrix Spike (MS): A second aliquot of sample is fortified with with a known concentration of target analytes and carried through

the entire analytical process. Matrix spikes evaluate potential matrix effects that may affect the analyte recovery.

� Reference Material (SRM): A homogenous material of similar matrix to the samples, certified for the parameter(s) listed.

Reference Materials ensure that the analytical process is adequate to achieve acceptable recoveries of the parameter(s) tested.

Each QC type is analyzed at a 5-10% frequency, i.e. one blank/duplicate/spike for every 10-20 samples. For all types of QC, the

specified recovery (% Rec) and relative percent difference (RPD) limits are derived from long-term method performance averages

and/or prescribed by the reference method.
