The 200,000th passenger MV – On July 7, 2010, Air Creebec and SEBJ celebrated the 200,000th passenger to travel aboard Air Creebec as part of the Eastmain-1-A/Sarcelle/Rupert project. Mario Lavoie, laborer for contractor CRT-Hamel, received a watch from Connie Ragusa, an Air Creebec representative, and a laminated print from Denis Lalonde, representing SEBJ.

MEM – Since 2002, thousands of people have worked on various aspects of the Rupert diversion project. By the end of 2010, ev-eryone will have to say goodbye. This significant, inevitable step will be taken with pride!

While hundreds of workers were still present at the workcamp, SEBJ organized activities to thank them and to highlight all the hard work that went into the project.

Thanks to the cooperation of the Eastmain and Sarcelle jobsites, tours were organized in July and August for workers from Nemis-cau workcamp. These workers really enjoyed discovering the other jobsites of the Eastmain-1-A/Sarcelle/Rupert project in the company of friends and co-workers. Thank you to all participants, guides and organizers!

The culmination of these Appreciation activities [activités Reconnaissance] was held on August 21. Site Manager, Gervais Savard, and Virgile Albert invited all employees and workers to a Rupert signature supper: pictures of the work-ers decorated the walls of the cafeteria, superb weir-shaped cakes were served and a video of progress at the jobsite from 2007 to 2010 was shown on a giant screen. The 2007–2009 souvenir album got a great reception, and the project’s colors were on display. An evening under the big tent followed, where laughter and memories joined to create memo-rable and touching moments!

The imminent end of the project should be celebrated and shared—shared with the emotion, enthusiasm and respect that we developed while working to accomplish this unique project.

ite Upstream sectorLP – Concreting of the three sections of the Sarcelle pow-erhouse’s water intake began in April 2009 and will end this fall. It has required more than 10,900 cubic metres of concrete.

One aspect of the special configuration of the intake’s openings is the shaping of the concrete above the gates. Two successive curves, known as lintels, will efficiently direct the flow to the generating units.

Although concreting is progressing rapidly, work at the water intake is not over. The arrival of workers from com-pany CIE Euler, assigned to install the stoplog slots and the trashrack slots, signals another step in the work on this section of the water intake.

ite Downstream sectorMV – Diffuser construction is coming to an end. By mid-September, more than 12,000 cubic metres of concrete will have been poured in this area.

The process of installing the steel structure of the service bridge’s deck began with the concreting of nine columns. These nine columns, three per unit, will be equipped with anchors to secure the beams of the bridge slab.

Powerhouse switchyardThe switchyard is bustling with activity. The six switchyard towers have been positioned on their bases. Around them, more than half of the insulators, circuit breakers and dis-connect switches are in place.

The two firewalls between the transformers have been completed, and the four columns supporting the wiring are 85% concreted. Construction of gravel-filled ditches for rainwater drainage, excavation of the fence site and form-work for the duct bank have begun. Meanwhile, installation of the grounding grid is continuing.

BULB UNITS

The first sectionsLP – The first sections of the bulb tur-bine units arrived at Sarcelle power-house in June 2009. Last year, only the armoring of the three units’ draft tube cones had been installed. A section upstream of the armoring will com-plete that area this year.

2010 is going to be a much more eventful year. The arrival of the stay rings, stator casings, sealing rings and upstream covers by road contributed to the bustle of activity.

At the jobsite, employees of con-tractor Alstom began installing the components of generating unit LS 23 in June.

Stay ringViewed from the outside, this section is located between the stator casing and the sealing ring. Inside, it contains the combined bearing, which consists of the thrust bearing, counter-thrust bearing and generator guide bearing, and the shaft through its centre. Composed of four welded parts, the stay ring is anchored by concreting a portion of the vertical stay vanes extending from its top and bottom. In addition, two lateral stay vanes have been welded to the stay ring; they will be anchored in concrete to hold the generating unit in place from either side.

On Sunday, June 27, three of the welded parts of the stay ring were installed in the powerhouse. This assembly, weighing just over 150 tonnes, was first placed at the bottom of unit 23 before taking its final, vertical position. It is kept upright by the lower stay vane, the lowest section of which will be concreted. The upper stay vane, attached to the fourth section, was welded in place on July 23.

LP – On Saturday, July 24, joint venture Cegerco Lambert and Somec delivered various premises that will belong to Hydro-Québec’s TransÉnergie division.

The six rooms that were delivered, in the presence of mem-bers of the Hydro-Québec team and SEBJ employees, con-tain protection panels, automatic control systems, electrical equipment, batteries and a laboratory. They are all located in the level 220 service area, adjacent to the future Sarcelle powerhouse switchyard.

PD – The Oujeck satellite workcamp, like all camps, had a limited lifespan. Oujeck workcamp was closed on June 20, and until weir construction is finished, the workers will live either at the km 257 workcamp or at the one in Waskaganish. At peak occupation, Oujeck workcamp housed more than 225 workers from several companies working on the Rupert weirs.

Closing a workcamp involves not only cutting its power, but dismantling it. Two contractors—Larouche Construction and Denis Lavoie & fils—started dismantling Oujeck workcamp in late August and will continue until late October. About 70 modules will have to be relocated. Some of the dormitories

will be moved to Nemiscau workcamp. The rest will travel nearly 1,650 kilometres to the Romaine project’s Murailles workcamp.

Users of the Route du Nord and the James Bay Highway will have to be careful, since the modules take up a good part of the road. Stop on the shoulder when you meet the escorted convoy.

Moving on and moving out

Level 220 is the top floor of the powerhouse, 220 being the number of metres it lies above sea level—level 0.

These rooms were delivered well ahead of the deadline, which was September 15. To mark this major step, a place mat com-memorating how quickly the work was completed was given to every worker, and a special cake was prepared for the occasion.

Congratulations to everyone who contributed directly or indirectly to this achievement!

KP 33 The weir at KP 33 is now in service, making it one of the most impres-sive of the eight hydraulic struc-tures on the Rupert River.

The left channel is permanently closed and water is flowing over the newly built weir. From now to mid-October, various types of fill will be placed to build the dam. Meanwhile, the temporary bridge will be dismantled.

KP 170Construction of the weir in the right branch of the Rupert River moved ahead quickly once the weir in the left branch had been started up.

The concreting has been complet-ed, as has levelling of the coffer-dam. Since mid-August, water has been flowing over the weir in the right branch, signalling the end of construction at this location. Reha-bilitation of the site has begun.

MEM – The summer was not exactly restful for workers at the Rupert diversion project. Although four of the eight weirs had been completed, those at KP 33, 170, 223 and 290 needed a lot of work—we can now make out their final shape. Even though the project is drawing to a close, everyone is still working diligently! Here is how work is progressing:

MEM – Fill work on the dam has been completed since mid-August. Contractor Newco is busy with jet grouting, which is expected to continue until the end of September. This technology, already used for the cofferdam, will ensure that the gravel core of the dam is watertight.

The next steps will be to dismantle the temporary bridge and remove the jetty, making it possible to complete construction of the spawning ground.

KP 290Startup of the weir in the central channel occurred in early August. Contractor Newco has completed con-struction of the cofferdams for building the rockfill weir in the right channel, and the temporary bridge has been dismantled.

The contractor is now installing the rockfill for the second weir.

Jolly BayNF – Since late July, a control structure has been under construction in Jolly Bay, about 3 kilometres down-stream of Rupert dam; it consists of a rockfill weir with sheet piles.

Its purpose is to preserve a body of water that will prevent fish mortality, to allow fishing and to provide an environment conducive to goose hunting.

Since the weir is more than 2.5 metres high and has a storage capacity of more than 3 hectares, it is subject to the Dam Safety Act, which introduced a series of measures governing construction and operation.

The second phase of concrete work is coming to an endJL – Though the civil works contracts are nearing completion, major concrete work is still underway at the Eastmain-1-A pow-erhouse.

In August, Cegerco–Inter-Cité (CIC) finished concreting the wall of the powerhouse access road. The company is also continuing concrete work in the turbine area. The generator floor, consist-ing of precast concrete parts, is also part of the contract. Keep in mind that the second phase of concrete work includes a total of over 27,700 m3 of concrete.

Gate slotsConcreting of the powerhouse’s 12 downstream gate slots ended on July 24. Nordex, subcontractor for Canmec Industrial, was responsible for concreting the slots, weirs and lintels.

The first pour took place on July 12; in all, it took only 12 days to fully embed these parts.

End of work at the temporary dikeNeilson-EBC finished dismantling the temporary dike at the water intake in mid-August. This involved removing the sheet piles, excavating the dike using a dragline excavator and, finally, reshaping the spur dikes. Water from the reservoir can now flow freely through the water intake.

Starting up the tailraceJL – Neilson-EBC finished excavating the tailrace in August. A total of 525,000 m3 of rock and 530,000 m3 of overburden had to be removed to clear the channel through which the turbined water will return to the bed of the Eastmain River.

The tailrace will be started up once the cofferdam downstream of the canal has been removed. Startup should occur in September.

Electrical and mechanical systemsWork on the first mezzanine (level 230) was completed a few weeks ago. The TAP consortium worked especially hard to deliver the mezzanine to Hydro-Québec by mid-August.

Finishing work, such as the installation of doors and acoustic tiles for suspended ceilings, was carried out by the consortium, which is also continuing to supply and install equipment and electrical and mechanical systems on almost every level of the powerhouse.

Assembly of the first turbineJL – Most of the parts necessary for putting together unit LC 11 have arrived at the powerhouse and the work of assembling the first turbine is underway (see other articles on pages 12 and 13). Turbine manufacturer Voith Hydro installed the casing of the stator directly in the turbine shaft and has begun assembling the magnetic circuit and the winding. Now that is precision work!

Rotor assembly, which will be done in the unloading bay of the powerhouse, will begin shortly.

CL – On July 28, the first wicket gates arrived at Eastmain-1-A powerhouse on a double semi-trailer. This truck with two trailers is the first of three required to deliver the 72 wicket gates—24 per unit. These parts, manufactured by Voith Hydro, were meticulously designed and manufactured to have an optimal hydraulic profile.

A key roleThe wicket gates will be inserted be-tween the turbine runner and the stay ring of each unit. They will be in direct contact with the water, where their role is to channel more or less water to the turbine runner depending on demand for electricity and operating strategy. Contrary to popular belief, it is the wicket gates—not the main gates of the water intake—that govern flow to the generating unit. Their role is therefore crucial.

How does it work?The water flows into the penstock and then to the scrollcase where it is evenly distributed by the stay ring. The water then reaches a second set of blades, which are adjustable: the wicket gates. Their opening (also called the gate position) can vary from 0 to 100%.

Well-traveled wicket gatesThe initial stage—design— was carried out at Voith Hydro’s factory in Germany. “The shape of the wicket gates was developed and designed specifically for the Eastmain-1-A generating units,” said Dany Morin, Voith Hydro Project Manager. “A scale model was used to adjust and check their hydraulic profile.”

Generating unitsThe wicket gates arrive at the powerhouse

Once the optimal shape had been es-tablished, “the 72 wicket gates were cast at Voith Hydro’s foundry in Brazil. Then, after being machined, they were sent by ship from Brazil to the United States,” said Mr. Morin. “The wicket gates for the first unit completed their long trip to the jobsite on a flatbed truck, while the other two sets are still in storage in Montréal,” he added.

InstallationAt the end of August, the first 24 were inserted one by one into the bottom ring of unit LC 11. The overhead travelling crane raised each wicket gate to its final position using the longer journal—the upper wicket-gate journal. The shorter journal will be inserted into the bottom ring. The head cover will then be fitted over the longer journal. Once installation is complete, the only visible part of the wicket gates will be their blades, which will remain in contact with the water.

The 24 wicket gates of unit LC 11 were inserted vertically between the stay ring and the turbine runner.

Land transportationIt was impossible for the ships to dock directly on the banks at the village of Chisasibi because of their size and draft, evaluated at more than 9 metres. Instead, a delicate ship-to-barge transfer operation was necessary—this took five days.

Finally, the first runner left Chisasibi on a specially prepared flatbed truck. The convoy took the James Bay highway and the Muskeg–Eastmain-1 road. The first runner was delivered to the jobsite on August 14. In all, the land transportation of the three runners lasted from August 13 to 21.

The runner for the first generating unit was lowered into the turbine shaft on August 28, nearly two months ahead of schedule.


After an ocean voyage from Brazil, along the continent and around eastern North America, three turbine runners arrived in James Bay before traveling by road to the Eastmain-1-A powerhouse.

JL – This unprecedented operation was required because of the unusual size of the Eastmain-1-A powerhouse’s three turbine runners. Since the runners weigh in at around 120 tonnes and have a diameter of about 7 metres, hauling them up the continent across so many roads and bridges would have been difficult, if not impossible. The only viable solution was to ship them.

A long tripA long trip covering thousands of kilometres had to be organized between São Paulo and Chisasibi. This enormous undertaking was meticulously planned over a year in advance.

“Our main constraint was the short period of ice-free navigation in James Bay, which only lasts from June to September,” said Jean-Pierre Motard, Section Manager – Project Control. “We had to make sure the manufacturing was completed in time for shipping to be done within this window.”

Turbine runners for the Eastmain-1-A powerhouseAn epic journey from Brazil to Chisasibi!

Turbine manufacturer Voith Hydro was responsible for manufacturing and transporting the Eastmain-1-A powerhouse’s three runners. It subcontracted the transportation to an expert in the field: Panprojects of the Panalpina group.

To minimize risks during transportation, the three runners were sent on two different ships. After travelling along the east coast and around Québec by way of Hudson Strait, the ships entered Hudson Bay and then headed down to James Bay. The first ship, carrying two runners, reached Chisasibi on August 8 and the second arrived three days later.

Since the ships could not dock directly on the banks at the village of Chisasibi, a delicate ship-to-barge transfer operation was required.

Each runner left Chisasibi on a specially prepared flatbed truck and travelled on the James Bay highway and the Muskeg–Eastmain-1 road.

Even before the turbine runners started to turn, you could say that they had “been around.” Manufactured in Brazil at the Voith plant, the runners had to be transported by sea because of their size and weight.

Why Brazil?The steel runners were cast in one piece. To protect against corrosion and cavitation, they were coated with stainless steel. Since no Canadian foundry is capable of produc-ing such large parts, Voith Hydro manu-factured the runners at its plant in São Paulo, Brazil. The three runners are the only components of all the James Bay projects that had to be transported by sea to their destination.

Not buckling up is still one of the leading causes of death on the road. Today, back-seat passengers are most often at risk. It is essential to avoid using certain devices intended to loosen seatbelts. They actually reduce seatbelt effectiveness and could lead to a risk of trauma in a crash. In fact, automakers have enhanced the performance of traditional seat-belts by installing pre-tensioner systems to tighten the belts and improve their ability to minimize occupant movement in a crash.

For maximum safety, there should be no slack in your seatbelt.

CL – Annie Villeneuve, the brilliant lawyer at the SEBJ head office, is every bit as interesting as the singer who shares her name. She loves to travel and her unique and colorful career is an accurate reflection of her personality: she is curious, eager to learn and determined to meet the many challenges facing the project of the decade.

Annie Villeneuve is a governmental approvals advisor who has been working at SEBJ for the Eastmain-1-A/Sarcelle/Rupert project since 2007. She answers to Philippe Mora and appreciates her team and the many challenges her work pro-vides. That work, which starts in

the earliest stages of the project, is done behind the scenes and sometimes goes unnoticed. So, what does she do? “For the most part, I advise and support man-agers so that SEBJ can obtain, within the anticipated timeframes, the government approvals it needs to carry out work in accordance with applicable environ-mental legislation. I also ensure compliance with the conditions stemming from the broad authorizations obtained for starting up this great project,” stated Ms. Villeneuve.

So much gets done behind the scenes

PRO

There are a number of steps involved in determining which approvals are needed and expediting the process of obtaining them from government departments.

Note that, since the project began, SEBJ has had to acquire nearly 1,000 sector-related authorizations and meet several con-ditions. “Every day, I work to ensure that these conditions are met and advise various stakeholders to ensure that our operations comply with legislation, as well,” she added.

Her master’s degree in international law, with a specialization in environmental law, gave wings to her legal career. She studied in Montpellier and Paris and worked in Rome, but it was at Hydro-Québec that she decided to put down roots in January 2007, joining the SEBJ team in early March 2007. “There are consider-able challenges at SEBJ. You have to be able to give the right advice at the right time, and a quick turnaround is required to meet tight construction schedules,” said Ms. Villeneuve, who is very proud that construction has never been delayed or stopped for lack of a timely authorization.

In addition to being responsible for transmitting documents to the various government departments, she will be participating in a major process that will require her services until 2012: public consultations. “One of the conditions the provincial Certificate of Authorization imposes on Hydro-Québec is to hold public consultations to find out what our Cree partners think of the ef-fectiveness of mitigation measures that were implemented as part of the project. I will be asked to prepare the documentation that shows that we fulfilled our commitments,” she said. This is another major challenge that she will undoubtedly meet with enthusiasm and flair!

MEM – If you’ve ever met him, he has definitely smiled at you. If you smiled back, you became one of his friends. Respectful and generous, Ghislain Lévesque is one of those people you never forget. Carpenter-joiner-cabinetmaker by trade, he works for Nemaska Eenou Company (NEC) doing technical mainte-nance at Nemiscau workcamp. With his very talented hands, he can build, renovate or repair anything.

This handyman is thankful that throughout his childhood his mother gave him planks of wood and bags of nails to build with! Most of his tasks relate to routine building maintenance, but some require a bit more creativity, which he loves! He is meticulous and a perfectionist.

Ghislain was born in Price (25 minutes from Rimouski) and now lives in Mont-Joli. He apprenticed as a steel erector for two years and owned his own business as a carpenter-joiner general contractor for six years. “I enjoyed being my own boss, but I’m very happy here. I have great conditions, the perfect work atmosphere and a tremendous team.” The idea of working on the James Bay projects came from his feisty personality, eager for challenges.

A smile is worth a thousand words!Despite being far away from the two children he is so proud of, he worked at the Eastmain project for two years (2005–2007) and the day after his birth-day, on March 25, 2007, he joined the group working on the Rupert diversion project.

No challenge is too great. Ghislain is ready for anything! In fact, three years ago he took up powered parachuting, enabling him to see the most beautiful landscapes of the James Bay area from above. He and the Cree workers around him respect one another, and Ghislain takes a real interest in their culture and lan-guage, of which he has learned several words.

Life isn’t always easy, but Ghislain has always had confidence in himself. “You have to believe in yourself, your ideas, your goals and your talents and then dare!”

Don’t forget to smile at him—he deserves it!

NF – Seeding of exposed banks is one of the measures being implemented to mitigate the impacts of the Rupert River diversion by reducing erosion and sediment transport on the one hand, and improving wildlife habitat, on the other.

Only areas with silty substrate that were more than 15 metres wide were selected, for a total of 155 hectares (ha); approximately 80% of these were in the section extending from KP 110 to 165.

The seed mix was the one SEBJ usually uses for revegetation of affected areas in humid conditions, and it was applied at a rate of 225 kg/ha. It should be noted that the seeds were coated with an environmentally safe lime-based product.

GDG Environnement of Trois-Rivières car-ried out the work from July 2 to 19. The operation was conducted from the Nemis-cau airport using two Piper PA-25 Pawnee aircraft with a load capacity of 500 kg. On site, the operation went very quickly since one hectare was covered every 15 seconds! The aircraft flew at a speed of 160 km/h, an altitude of about 10 metres and, of course, in low- or no-wind conditions (<15 km/h).

On the ground, the marking of planting plots and quality control of application rates was carried out by a team from environmental consulting firm Biofilia.
