CEEQUAL Case Studies
Stockholm Extended Metro – Arenastaden
CEEQUAL Excellent (82.3%) – Client and Outline Design Interim Award
Version 5, March 2021 | Stockholm, Sweden
Assessors: Kaisa Nugin & Erica Rodén, Region Stockholm
Verifier: Ric Collinson, Atkins
Client: Administration for Extended Metro, Region Stockholm
Designers: WSP, Rundquist Arkitekter AB
The extension of the Stockholm Metro is vital to make Stockholm a vibrant and accessible city with a sustainable public transportation network. Today, a quarter of Sweden's population lives in Stockholm County, and every year this figure increases by 35,000 inhabitants. As one of the fastest growing regions in Europe there is an increasing demand for housing as well as improved public transportation.
The expansion of the metro is divided into seven projects. The Arenastaden project includes the extension of the Metro from Odenplan to Arenastaden in Solna, the so called "Yellow metro line". The project includes a total of 4.1 kilometres track tunnel and three new stations: Hagastaden, Södra Hagalund and Arenastaden. Around 11,000 new residencies are being built near the new stations. When the "Yellow line" is completed, around 80,000 people will work in the nearby area.
The metro will be located below ground and the tunnels and platforms are constructed in rock. Only the entrances of the new stations will be visible above ground.
The art on the Stockholm Metro is often called the world's longest art exhibition. All the new stations will get their very own features and art design. The art is important for making the environment interesting for commuters and memorable for visitors to the Stockholm area.
The Stockholm Metro will be extended by 4.1 kilometres.
All track tunnels will be constructed in rock.
670,000 cubic metres of solid rock will be blasted out.
37,000 cubic metres of concrete
will be used.
Operation of the extended lines is
planned for 2028.
Sustainability is an integrated part of the project, from localisation and early planning throughout construction. Competence in relevant sustainability issues has been present in the client's project management as well as the management of the design team. A coherent team, which has been the core of the project from the start in 2014, has pushed sustainability issues and made tough decisions on planning and design to increase end user value. For example, the project has developed from the originally planned shuttle between Odenplan and Arenastaden, into a continued extension of the existing green metro line. Another example is the incorporation of a new metro station at Hagalund, making the metro accessible for the future residents of a one of Stockholms evolving townships.
On a more detailed scale, design features of the new metro stations ensuring user experience, accessibility and safety have been preserved, despite a strict economical budget and many compromises to keep projects costs within budget.
In Sweden, the legal requirements on infrastructure projects demands for a formal process including extensive investigations on the project's impact on people and the environment as well as continuous consultations with stakeholders and the local community. However, the project management has pushed sustainability of the project to a level for beyond that stated by Swedish environmental law.
The extension of the metro line is a large-scale infrastructure project, which will affect a lot of people. The construction phase takes several years and is carried out in the densely populated area of Stockholm. As the construction phase is finished, the new metro line will constitute a vital part in the development of the Stockholm Region and will provide new opportunities for travelling within the Stockholm area.
A key to a successful project is the involvement of stakeholders and the local community throughout the planning and design process. Several surveys, investigations and assessments have been conducted as a basis for decisions on the localisation and design of tunnel tracks and metro stations as well as the decision on construction methods.
Activities to involve stakeholders and the community include open houses, meetings with stakeholders and the public, digital surveys, attitude surveys and newsletters. Consultations with the public have been conducted in various stages and in several places along the planned metro extension.
Investigations, reports and assessments have been available on Region Stockholm's website for easy access to those concerned and anyone interested.
All opinions and comments have been evaluated by the project team to determine whether it entails revisions of the design works or methodology for implementation. Views are summarised and responded to in a consultation report, which is published on Region Stockholm's website.
Land Use and Landscape
The process for choosing the location of track tunnels and metro stations has been extensive and has been conducted in accordance with the Swedish formal process for railway plans. The aim of the process is to find the localisation which provides the greatest benefits with least impact on environment and the community. Several alternative localisations have been evaluated with regards to factors such as availability and accessibility for future travellers, the environmental, geological and technical conditions as well as the impact on natural and cultural assets, existing structures and the development plans of affected municipalities.
The project is located in an urban area and all of the new tracks will be constructed in tunnels. Only the entrances of the new stations will be visible above ground. The locations of the new stations have been chosen to provide easy access for future passengers, and with as little negative impact as possible on natural and cultural assets, existing structures and the local community. Some of the stations will be constructed on the ground floor of new or old buildings and others in their own buildings.
The Water Environment
The project is not located adjacent to any water resources. However, as the project is located mainly below ground level it will impact water by the potential lowering of ground water levels. During the construction phase there will also be a discharge of process water and storm water.
Several protective measures are taken to prevent the effect on ground water levels including grouting of tunnels and infiltration of water. Buildings located within the project's immediate environment are inventoried based on their sensitivity to groundwater lowering. Groundwater levels are continuously monitored in accordance with a comprehensive control program.
During the construction stage both storm water and process water undergo wastewater treatment before discharge and control measures are in place. During the future operations of the metro line, there will be a permanent water treatment plant in place for drainage water. The design allows for drainage water to be led to infiltration wells and be used to refill groundwater.
Since the project is below ground there are few hard surfaces that generates water runoff. The only new building constructed will have a green roof that can retain runoff.
Physical Resources
The use and management of physical resources has been integrated in project management throughout the project, from early planning and localisation throughout construction.
During the planning and design aspects such as resource efficiency, accessibility and user value have been integrated in the process in order to find the best solutions possible. For example, to increase accessibility for travellers, the project was developed from a shuttle between Odenplan and Arenastaden to a continued extension of the existing green metro line. Another example to increase the resource efficiency is the incorporation of a new metro station at Hagalund, making the metro accessible for the future residents of a one of Stockholm's evolving townships.
During design and construction, the project team has worked with action plans for increased resource efficiency and limited climate impact. Calculations have been made of the resulting effect of taken actions as well as the estimated carbon footprint of the various project phases.
To prevent the use of chemicals and construction materials containing hazardous chemical substances, the Swedish system "Byggvarubedömningen" has been used. All chemical products and construction materials are logged and evaluated based on their content of hazardous chemical substances as well as percentage of renewable materials, reused materials, emissions, renewable energy during manufacturing, and packaging methods.
Several trainings and workshops have been conducted with staff from the client's organisation as well as with designers and the construction workforce. The workshops have resulted in actions as well as increased knowledge and awareness about the project's impact and possibilities for improvements throughout the project phases and organisation.
"I am proud of the willingness to take on challenges within the project team! It is the creativity and agility of the team members that lay the foundation for a sustainable Metro."
– Malin Harders, Project Director, Arenastaden
CEEQUAL's Role
What were the main challenges for the project and how were these overcome?
The main challenge for the project was to design and construct a metro in a densely populated urban area, affecting the possibilities for design as well as methods for construction. Extensive consultations with stakeholders and local community, from early planning throughout construction, was the key to overcome this challenge and make the project possible.
What were the drivers and perceived benefits for undertaking a CEEQUAL assessment?
CEEQUAL has provided a framework for dialog on sustainability issues between the projects within the Administration of the extended Metro as well as between stakeholders within each project. The use of CEEQUAL has also enabled sustainability performance of the project to be measured against international standards and has facilitated in creating a systematic and integrated sustainability work.
How did the use of CEEQUAL influence the outcomes of the project?
In Sweden, the planning and execution of infrastructure projects is regulated by Swedish law, which means that the project's impact on stakeholders, the local community and the environment is investigated and mitigated. CEEQUAL has provided the framework for working with sustainability aspects, which are not regulated by Swedish law as well as to raise the general level of performance in sustainability.
What elements of this project highlight best practice and innovation?
Sustainability has been an integrated part of the core of the project and the project management. All parties engaged in the project have signed a contract for cooperation, which stipulates sustainability as one of the focus points. This has influenced the cooperation of all engaged in the planning and design of the Metro extension.

Q: Fastest way to compute k largest eigenvalues and corresponding eigenvectors with numpy I have a large NxN dense symmetric matrix and want the eigenvectors corresponding to the k largest eigenvalues.  What's the best way to find them (preferably using numpy but perhaps in general using blas/atlas/lapack if that's the only way to go)?  In general N is much much larger then k (say N > 5000, k < 10).
Numpy seems to only have functions for finding the k largest eigenvalues if my starting matrix is sparse.

A: Actually the sparse routines work for dense numpy arrays also, I think they use some
kind of Krylov subspace iteration, therefore they need to compute several matrix-vector
products, which means that if your k << N, the sparse routinescould be (marginally?)
faster.
Check out the docs
http://docs.scipy.org/doc/scipy/reference/tutorial/arpack.html
and the following code (go to take a good coffee with friends until it ends)
import numpy as np
from time import clock
from scipy.linalg import eigh as largest_eigh
from scipy.sparse.linalg.eigen.arpack import eigsh as largest_eigsh

np.set_printoptions(suppress=True)
np.random.seed(0)
N=5000
k=10
X = np.random.random((N,N)) - 0.5
X = np.dot(X, X.T) #create a symmetric matrix

# Benchmark the dense routine
start = clock()
evals_large, evecs_large = largest_eigh(X, eigvals=(N-k,N-1))
elapsed = (clock() - start)
print "eigh elapsed time: ", elapsed

# Benchmark the sparse routine
start = clock()
evals_large_sparse, evecs_large_sparse = largest_eigsh(X, k, which='LM')
elapsed = (clock() - start)
print "eigsh elapsed time: ", elapsed

A: In SciPy, you can use the linalg.eigh function, with the eigvals parameter.

eigvals : tuple (lo, hi) Indexes of the smallest and largest (in
  ascending order) eigenvalues and corresponding eigenvectors to be
  returned: 0 <= lo < hi <= M-1. If omitted, all eigenvalues and
  eigenvectors are returned.

Which in your case should be set to (N-k,N-1).

Duckweed can be recognized by its small, single or grouped, round to elliptical-shaped clover-like floating leaves, with a root that hangs from the underside of the plant. Duckweed and Watermeal are the smallest aquatic plants known. Duckweed reproduces by budding and fragmentation. These minute plants serve as food for numerous organisms, they are especially important as a good source for waterfowl. While these plants are small, they can reproduce prolifically and quickly cover pond surface when growing conditions are right. A duckweed infestation can block sunlight from reaching deeper parts of the pond, preventing underwater plants from photosynthesizing and producing oxygen. In turn, that lack of oxygen can stress or kill fish.
These plants require a lot of nutrients to grow, so typically they are found in nutrient-rich environments such as ponds that receive drainage from farm fields, excessive runoff, septic systems, lawns and golf courses. The bottom sediments of infested ponds are often very mucky and nutrient rich. To prevent its overabundance it is necessary to reduce fertilizer application near the pond, maintain septic systems properly, redirect nutrient-rich runoff away from the pond and maintain a vegetative buffer strip around your pond. If the excess of nutrients are not addressed, plant overgrowth will always be present and it will need to be constantly managed.
Duckweed can be spread from one pond to another by humans, wildlife, pets, and birds. The small plants stick to the sides of boats, or lodge in the feathers of birds swimming in infested waters. When the boat enters a new body of water or the birds migrate, plants can go with them.
Beneficial Bacteria Products and enzymes such as PZ-900 feed on nutrients in the water making them unavailable for plant growth. Reducing nutrients can help prevent invasion.
Physical control of duckweed is usually accomplished by netting or raking the plants off the pond and then disposing of plant material away from the pond so that the wind or runoff cannot transport it back into the water. Physical removal along with chemical control and a reduction of nutrients entering the pond will maximize success.
Surface Aeration has also been used as a mechanical approach to hinder duckweed proliferation. Duckweed prefers to grow in stagnant water, aerators will disrupt the surface of the water and limit the growth of these plants to the sides of the pond where they can easily be removed using nets or a rake. Furthermore, the added oxygen will accelerate the decomposition process of nutrients that feed pondweeds and algae during the summer months.
Sonar AS & Sonar RTU, Reward, Weedtrine-D, and Propeller have been proven successful in treating Duckweed. A nonionic surfactant such as Cygnet Plus should be mixed in solution with specific herbicides when plants are treated.
* Sonar AS & Sonar RTU are ready-to-use products and do not require a surfactant such as Cygnet Plus for proper application.
Sonar AS is long lasting systemic herbicide ideal for water bodies with minimal flow or discharge. Simply mix Sonar A.S. with water and pour in different spots around the pond.
Sonar RTU (Ready-To-Use) is a long-lasting, systemic, easy to use herbicide. Sonar RTU does not require mixing, it can be applied directly from the bottle by simply pouring into multiple locations around the water body.
Propeller is a broad spectrum, fast acting, contact algaecide & herbicide. It comes in a water-soluble granule that mixes with water to be sprayed directly onto the target plant. Propeller should be applied to actively growing plants or algal blooms.
Reward and Weedtrine-D are both broad spectrum, rapid-acting, contact herbicides ideal for use on small bodies of water or small weed patches. Successfully control a broad range of submersed, floating and emergent weeds in lakes, ponds, and drainage ditches. Rapidly absorbed by foliage, Reward and Weedtrine-D herbicide begin to work immediately on contact.
Cygnet Plus is a nonionic wetting agent, sticker, activator, and penetrant all in one. Cygnet Plus Increases the effectiveness of herbicides uptake into the plant tissue.

Het regentschap Oost-Sumba (Indonesisch: Kabupaten Sumba Timur), met een oppervlakte van 7000 km² is onderdeel van de provincie Oost-Nusa Tenggara (Indonesië) en ligt op het oostelijke deel van het eiland Sumba tussen 9 16' and 10 20' zuiderbreedte en tussen 119 45' en 120 52' oosterlengte. Het regentschap grenst in het noorden aan de Sawuzee en Straat Sumba, in het westen aan het regentschap West-Sumba en in het zuiden en oosten aan de Indische Oceaan. Er wonen ongeveer 190.000 mensen, dat is ongeveer één derde van de totale bevolking van Sumba. De bevolkingsdichtheid is 27 inwoners per km². 56 procent van de bevolking is jonger dan 24 jaar.
Oost-Sumba bestaat uit vijftien onderdistricten. De hoofdstad is Waingapu (± 11.000 inwoners).

Transport
 De afstand tussen Waingapu en Waikabubak, de hoofdstad van West-Sumba, bedraagt 137 km. De busrit duurt twee à drie uur.
 Bij Waingapu ligt het vliegveld Mau Hau. Vanuit Denpasar op Bali zijn er twee vluchten per week door Pelita Air en één vlucht per week door Merpati Airlines. Een enkele reis kost ongeveer 700.000 rp (2007).

Taal
In Oost-Sumba worden, naast het Indonesisch, twee talen gesproken:

 Kamberaas (234.574 sprekers in Oost-Sumba). Het Kamberaas is de enige inheemse taal van Oost-Sumba en neemt het grootste taalgebied van Sumba in beslag.
 Savoenees (20.000 sprekers in Oost-Sumba). Het Savoenees is de oorspronkelijke taal van de Savoe-eilanden Savoe en Rai Jua, maar in de Oost-Sumbanese steden Waingapu (westen) en Melolo (oosten), beide aan de Straat Sumba, wordt deze taal eveneens gesproken.

Klimaat
Oost-Sumba is beduidend droger dan West-Sumba dankzij het droge seizoen van bijna zeven maanden (april t/m oktober). De jaarlijkse neerslag bedraagt slechts 800 tot 1100 mm waardoor het landschap dor en droog is. Er zijn vaak grote sprinkhaanplagen.

Gezondheidszorg
Malaria en tuberculose zijn endemisch op Oost-Sumba

Trump on Nancy Pelosi's 'Crumbs' Comment: 'She's a Rich Woman Who Lives in a Big, Beautiful House in California'
Andrew Burton/Getty
President Donald Trump responded Monday to House Minority Leader Nancy Pelosi's claim that his new tax reform law would only offer "crumbs" to workers. "She's a rich woman who lives in a big, beautiful house in California, who wants to give all of your money away," he said.
Trump responded to Pelosi during a speech at the Sheffer Corp. in Blue Ash, Ohio, which gave its workers $1,000 each in a bonus made possible by the tax cut.
After detailing the benefits of the tax cut, and after inviting employees of the company to speak about how it would help them, Trump said:
So Nancy Pelosi, again, said that's "crumbs." Well, she's a rich woman who lives in a big, beautiful house in California, who wants to give all of your money away. And she talked about "crumbs." And I really think her statement about "crumbs" — 'cause you're getting thousands and thousand of dollars, and you're getting it every year — so I think her statement, "crumbs," will be equivalent — and I said this the other day for the first time — when I first heard the word, "deplorable," I thought it was a bad thing, but I had no idea it was not going to be good for our opponent [Hillary Clinton]. It was not good. Because about two days after she said it, I go to a rally, and everyone's wearing shirts, "I am a deplorable," "We're all deplorables," I said, "What's going on with the word 'deplorable'," Rob, you know, we had that, right? (Applause) It just went pretty wild. It was not a good day for her. And I think this is not a good day for Nancy Pelosi. She's our secret weapon. (Laughter) No, she's our secret — I just hope they don't change her! There are a lot of people who want to run her out. She's — she's really out there. And I'm supposed to make a deal with her?
Pelosi would be Speaker of the House if Democrats take control of the House of Representatives by winning 24 seats in November.
