Three Years!

• Intake maintenance gate excavation (upstream of

existing dam) is now complete. Form and concrete

work to begin;

• The 60 metre intake shaft (downstream of dam) is

nearly complete, reaching the elbow point at the

bottom where it will connect to the power tunnel;

• Power tunnel is progressing toward the dam and

has reached the location of the surge shaft. Once

some preparation is completed, progress will

continue simultaneously on both the surge shaft

and power tunnel;

• Pilot hole for the 110 metre surge shaft completed;

• Concrete placement work well underway in the

powerhouse cavern; and

• Main access tunnel progressing well.

Project Status

Powerhouse cavern.

• June-February 2017:

Concrete work for

generator units in the

powerhouse;

• July: Main access

tunnel meets Adit D;

• July: Boring to begin

on surge shaft, working

from the bottom, up;

• November: Installation

of piping, pumps at

tailrace outlet

complete; and

• December: Excavation

under the John Hart

dam. Expected to be

complete in January

2017.

Project Schedule

Power tunnel excavation has now

progressed past the surge shaft.

We have a new time lapse camera on the site, and this will take constant pics of the powerhouse cavern to show the advancements over time.

Placement of form work, rebar and concrete for the sump areas that go underneath each of the three

turbines. Carpenters are working two shifts per day, 10 hours per shift, to build the wooden forms for the

concrete. There are now about 360 people working on the project in Campbell River. Much of this

increase is in carpenters for the concrete form work, iron workers and a few millwrights/labourers.

A temporary crane was installed this month to help move in equipment and place

concrete.

Environment Update

17

While many are focused on the daily work required to make the John Hart project a success, the

environment team is thinking in terms of years – looking ahead to 2018/2019 when a

comprehensive replanting process will begin:

• Restoration plans will combine both density planting and natural means: in areas next to

broom stands, high-density planting will be required;

• Allowing restoration by natural means still requires work from the project team as they

manage invasive species and create ‘rough and loose’ terrain to encourage the spread of

natural species;

• Because new plantings are required to be ‘2-year stock’ – plans for the earliest stages of

restoration beginning 2018 are required now to ensure the plants meet that age requirement;

and

• Focus at this time is on project impact areas – areas where construction is underway now.

The restoration plan for the penstock corridor will be developed at a later date.

People Profile – Valerie Masterman

Background:

Valerie is a Registered Professional Biologist (RP Bio) with a Bachelor of

Science from the University of Toronto and Master’s Degree in

Environmental Management from the University of Nottingham (UK). She’s

worked with Hatfield Consultants for almost 10 years on a range of projects

from water resource planning in Southern Africa to Agent Orange

contaminant pathway Investigations in Viet Nam, to environmental auditing

of the South Fraser Perimeter Road Project in the Lower Mainland.

Home:

Valerie grew up on Quadra Island before setting sail at the age of 17 for a

2-year International Baccalaureate term in Singapore. Since then she’s lived

in Toronto, Nottingham (England), India and Vancouver before moving back

‘home’ in 2014 for the John Hart project. Here, Val and her family (husband,

Stu, daughter Zoe (2) and soon-to-arrive baby) can be near family.

Hobbies:

Being outside is what matters most for Valerie and family: from rock climbing to sailing, hiking to skiing, being active outdoors is their main hobby.

Project Responsibility:

As on-site environmental coordinator, Valerie is responsible for guiding the constructor (ASL-JV) in environmental matters, including mitigation and compliance. Her position is shared between SNC-Lavalin and ASL-JV.

“I wanted to come back and be close to home – this job was that opportunity, and then it became the best job ever.”

Construction – Point Of Interest

Each month, BC Hydro and InPower BC will provide a construction

fact, occurrence, or situation.

SNC-Lavalin GEMS environmental Audit.

The John Hart Generating Station Replacement Project is one

of the best in the world when it comes to environmental

performance according to SNC-Lavalin’s corporate

environmental audit system:

• GEMS (Global Environment Management System) is the

way that SNC-Lavalin monitors the quality of

environmental protection on its projects around the world;

• It includes an annual audit conducted by GEMS

representatives which assesses 16 topic areas including

sediment control, flora and fauna, and environmental

record management systems;

• Last year, the John Hart project received a 97 per cent on

its assessment, and in the 2016 audit (conducted in mid-

June), the project managed to improve that number to 99

per cent; and

• This puts this project at number one in environmental

performance for all of SNC-Lavalin’s projects around the

world.
