ST. JOBSVEEM AR1A020^AM TECHNICAL STUDIES

INTRODUCTION Jobsveem is a former warehouse and now a state monument on the Lloydpier in Rotterdam.

It is a rough, dark and sturdy building. Jobsveem has a closed character to protect goods from too much daylight, rain and wind.

With the redesign from warehouse to residential building, daylight has entered the structure.

The unique character has been retained, but three glazed atriums introduce daylight as well as views to the adjoining dwellings. Located in the atriums are the main stairways, lifts and entrances for the ground floor; a lively lightfilled space where residents meet one another.

The admission of daylight and the availability of lofts with floor areas as required have resulted in a unique building.

LOCATION TECHNICAL STUDIES ST. JOBSVEEM R’DAM

Zoomed in on location

Location

Arial view of location

The history of the Lloyd district goes back to around 1900. Increasing industrialisation and a rising volume of goods led to the construction of new docks such as Schiehaven, St. Jobshaven and Parkhaven.

The old warehouse was completed in 1913, and was located next to the St. Jobs haven.

From this haven the warehouse got the nickname: st. Jobsveem.

Building concept:

Opening facade, by making big glass atria horizontally through the building

Concept: Taking Entrepot building as an example, but turning direction of the atrium from vertical to horizontal.

Because the building is an old warehouse and had to become a residential environment with totally different requirements, the main challenge was to get enough light into the building.

The dimensions of St. Jobsveem made it impossible to make a custom vertical atrium. Instead of this solution Mei Architecten made three atria from facade to facade.

Sloping roof, derived from the line of the warehouses.

The dimension of the total building is 130 x 25 x 30 meters.

The hight of the floors decrease from groundfloor till fifth floor. Only the new penthouses added by Mei Architecten are an exeption to this rule.

MONUMENT STATUS TECHNICAL STUDIES ST. JOBSVEEM R’DAM

Monument In 1999 St. Jobsveem was declared as state monument. According to Dutch regulations this means that the building is protected against demolition, obstructions or changes.

Only the mayor and the city council can rule over any applications for changing any segment of a monumental building.

In the case of St. Jobsveem, quite a few alterations were made in the facade, changing the visual of the building. Here the city council ruled that for this specific building these changes were acceptable in the light of the additional quality it would bring to the dwellings.

THE BUILDING The length of the building gives it a strong direction. The design of the distribution is mostly defined by this. Only on the groundfloor and penthouse are exceptions; here the directionality is perpendicular to the length.

The upper floors of Jobsveem are marked by endlessly long floors with cast-iron columns. The lack of bearing walls meant that the floors could be subdivided as required. The same flexibility can be found in the floor plans of the dwellings.

The larger part of the building is used for residential functions. Again apart from the ground floor which is used for commercial purposes. Also storage and parking are situated on the ground floor.

In the upcoming chapter we will indicate how this directionality affects the apartments in distribution, usage and views.

BUILDING DISTRIBUTION TECHNICAL STUDIES ST. JOBSVEEM R’DAM Distribution path

Axonometry view of the distribution

Distribution (1): The distribution of the building is organized through three main atria that develope from ground level to the top floor. Every atrium is equipped with a staircase and an elevator, which allows the dweller to reach the hallway to their apartment. On the top floor, only the penthouses next to the atria are served by the hallway; the other dwelling units are splitlevels, and therefore accessible from the level below.

Distribution and functions (2): The St. Jobsveem building is six stories high, with slighlty different floor-hights; the only exception is the ground floor, which is an almost double-highed space. In the design it is divided into different commercial spaces apart from the north end, which is used as parking and storage room. The commercial spaces on the ground floor are directly accessible from Lloydstraat or Jobshaven and some of them from the atria too. As for the apartments, there are ten different typologies, basing on dimensions and kind.

N Siteplan

Parking: At the St. Jobsveem building there are ten parking spaces on the ground floor at the nothern side of the building. The rest of the parking lots is located outside the building, mainly on Lloydstraat. This choice of location is probably due to the high value of the ground floor of the building as commercial space.

PARKING DESIGN OPTION TECHNICAL STUDIES ST. JOBSVEEM R’DAM Residential function Vertical distribution Commercial areas Parking areas

Long section

Parking option: During the elaboration of the design, the architects thought of an alternative way to arrange the parking of the St. Jobsveem building.

Instead of placing only ten parking lots on the north end of the groundfloor, the proposition organized twenty-seven parking lots in a vertical compartment placed on the northern side of the building. This option allowed to increase the number of parking, but at the same time covered the pattern reminding the existence of a previous building. In the end the studio decided to stick to the previous solution, both for economic and renovation causes.

Different views from the building

Section of the siteplan

View: The St. Jobsveem building is located on the west waterfront of St. Jobsveemhaven. The inner composition and the central hallway distribution create on-sided apatments, a part from the penthouses. Therefore the largest number of apartments have only on external facade, and they are equally divided into waterfrontfacing units and inner-facing units.

THE FACADE A large part of the facade of St. Jobsveem was already defined by it being a renovation project.

This fact can be seen as a challenge to make an existing building with a story into something of your own. The three big atria which are characteristic for the total design also have a strong apparence in the facade. And besides adding big glass surfaces Mei Architecten also made St. Jobsveem their own by keeping some old warehouse elements that they found characteristic. They even added new elements that seem like they belong in the old warehouse construction.

In this chapter we will first analyse the facade proportion, where we try to find out why the atria are placed on these locations. After the proportions we will zoom in further and further on the glass facade of the atria and finally we will look at the reconstructed warehouse elements.

Proportion: The proportions of the building are defined by the three main atria, whose insertion is very visible in the elevations. The dimensions of the three entryways are similar, but not constant; that is a result of placing them in different parts of the building, without following a rigid geometric scheme. The solution is non-symmetrical but nontheless proportioned facades.

Outside inside The atria had to be considered outside area’s because of the fire regulations. Mei Architects had to make a design which creates an atria which seems like an indoor space but classifies to an outdoor space considering the fire regulations.

The solution was found in closing the big openings in the facade with glass lamells. Rain and heavy wind will kept out but air will flow through the building. The distance between two glass lamell is exactly the thickness of the wall. This creates a depth that refers to the risalit of the old building.

2 Detail 1 Through the glass facade toward street- and waterside, Mei architecten should solve many requirments at once: there are about how to allow more sun light inside with reinforcing the original structure, how to control a strong wind and refresh air with keeping temperatrue, and how to make outside space in the building considering fire regulation.

In Glass facades, there are steel plates, pre-tension iron cables, glass plates, and devices to hold glass panels and cables, allow to move limitedly, and link to steel plate.

Double layered glass facades are able to reduce the strenght of wind, allow to ventilate air and more sun light inside, make atria outside for fireresistance regulation.

Detail 2 Mei Architecten suggested the big glass facade street- and waterside. To fix whole glass facade, the architect suggested two methods to fix steel framework and glass facade.

The first is a pre-tension method to hold courtain-wall glass by using a holding device and iron cables to hold them.

Another is anchoring which is in order to fix the steel framework and is also for holding steel beams with the glass facade. Factory-producted Steel-concrete garders attached behind the masonry loading facade in order to make the point to hang them.

Detail 3 Iron cables to hang steel plates on and hold glass plates should be affected by strong wind and thermal change. To prevent its structure from crashing between glass plates or the collapsing the pre-tension cable facade it is allowed to move limitedly; back and forward, horizional direction, and vertical direction. In order to realize its limited movement, Mei architecten adopted a new type of detail to hold both glass plate and iron cable. There are two different types of device, detail: one is for holding only one glass panel, and another is to link two panels. Leg and inox plate on those details help to move the cable and glass plate without any crash and collapse.

NEW TRADITIONAL BALCONIES

Characteristic elements The architects found it very important to keep elements of the old warehouse intact. They payed a lot of attention to the wooden doors, that are characteristic for the building, by: - placing the appartments, so that every appartment has a characteristic opening.

- making a slidedoor system to mentain the wooden doors, that could’t be opened the original way because of the floortopping that was needed.

The balconies lost there function, but the cast was placed back were could. The small ‘houses’ which were used to distribute goods changed in function, becoming storagespaces for the penthouses.

BUILDING PHYSICS Renovating an old building always provides challanges when it comes to building physics.

At St. Jobsveem these were pushed even higher by the fact the building changes function: from storage building to residential building. Which means a lot of measurements needed to be taken in order to create dwellings in this building that are up to present days’ standards.

In this chapter we will take a look at the daylight and sound measures that were taken to improve living conditions, as well as cover all the fire safety measures in St. Jobsveem.

In order for this large, dark storage building to be made suitable for dwellings, additional daylight needed to be brought inside.

Since the building is a lot longer than it is deep, it would have been difficult to get daylight to penetrate the building by making central atriums. Therefore three atria were made, cutting through the complete short end of the building bringing more light inside. The apartments not adjacent to one of the three atriums officially do not conform to the modern standards of daylight according to NEN 2057:2001. (In this NEN-norm instructions are provided on how to calculate the amount of daylight that enters the building). But due to itâ&#x20AC;&#x2122;s monument status, and the spectecular views from these apartments this issue has been forgiven.

Climate (2) Flanking noise was big a problem for the building. Several options were considered to try and improve the acoustic properties.

Dilatation of the wooden beams was considered to prevent sound from traveling through the floor, they tried to apply iron blocks onto the beams to reduce vibrations and plasterboard was added to the seperation walls. None of these options proofed to privde a significant reduction of the flanking noise, therefore none of these options were actually applied to the building and instead compensation was asked.

(NEN 5077:2008 contains detailed instructions on calculating the transmission of noise) The only addition that really improved the acoustic properties was the concrete layer that was poored onto the floors. They agreed that additional measures will be added when residents encounter problems.

FIRE COMPARTMENTS TECHNICAL STUDIES ST. JOBSVEEM Râ&#x20AC;&#x2122;DAM

60 min fire resistant 30 min fire resistant 30 min smoke resistant

Fire safety (1) Even though St. Jobsveem is a renovation project, due to the change of function (storage > dwellings) the building has to meet requirements of a new building.

The building is divided into fire compartments of < 1000m2. Every apartment is viewed as a sub-fire compartment.

The NEN-6068:2008 norm describes all the minimum requirements for the fire compartments to prevent the fire from spreading.

Fire safety (2) The atrium, used to ventilate adjacent apartments, can not be viewed as outside envirement in case of fire. It can however be used as smoke exhaust system.

To achieve this smoke is exhausted through opened windows in the roof and fresh air is added through horizontal blinds in the facade of the atrium to provide a steady flow of air.

The apartments connected to the atrium are outfitted with smoke resistant glass (NEN-EN 1364-3). To ensure itâ&#x20AC;&#x2122;s functionality as smoke exhaust system there are restrictions to the use of the atrium.

The NEN-6068:2008 norm (mentioned earlier) also provides the necessery information on smoke regulation in case of fire. This was used to design the smoke exhaust system in the atria.

FIRE ESCAPE ROUTES TECHNICAL STUDIES ST. JOBSVEEM Râ&#x20AC;&#x2122;DAM

escape route smoke free zone

Fire safety (3) Every apartment entrance needs at least two escape routes. Interestingly six of the penthouse apartments only have one escape route.

It is allowed to escape through smoke filled corridor when the length of the corridor doesnâ&#x20AC;&#x2122;t exceed 30m.

Extra staircases were added at the ends of the corridor to provide for a second escape route.

And surely the NEN 6088:2002 norm was applied to provide clear directions to the fire exit routes.

Fire safety (4) The original cast-iron construction is not able to retain it’s stability during 120 minutes and is therefor painted with 120 minutes fire resistant coating.

The newly added steel beams are said to be already 120min fire resistant.

The requirement for 120 minutes can be reduced by 30 minutes when the permanent fire load of the building is less than 500 MJ/m2.

Due to it’s original wooden floors and wood/ steel support construction this is not the case for St. Jobsveem.

Building method & Construction St. Jobsveem is the early of 1900â&#x20AC;&#x2122;s monumental structure which was a loading and unloading warehouse at Lloydkwartier, Rotterdam. The interesting aspect is that St. Jobsveem has two different characters of its construction: One is this building shows traditional materials and structure system. Another point is the architect adopted beam and column system like L Corbusierâ&#x20AC;&#x2122;s Dom-ino system. With two different types of structure system, St. Jobsveem was able to stand even thoug the lenght of the building along the waterside is longer than the short end.

Because of its well-organized construction, there was a big challenge for Mei Archtiecten to transform to a residential housing.

In this chapter, first, we will review what are the original structures and how to relate each others.

Next, we will indicate what are new structures to support the old building, and the process to revitalize it with temporary structures during its construction.

1. Original condition St.Jobsveem has one long side, so a stability wall was in the midddle of the building to hold masonry loading facades not to twist or fall down.

2. Removing Stability Wall To modify from warehouse to multi housing, the statility wall and around it was removed in order to make contiuous space.

3. Temporary structures After removing the stability wall, original structure like manosnry facades, timber floors and beams, and so on should be reinfoced by temporary structures in order to prevent the building from destroying. The temporary structures also played a important role when the destruction of parts of buildings to create new addtional structures like steel framework for atria, steel-stairs, and parallel structures.

4. New additional structures There are two different types of new structures for sturcutural stability; One is a steel framework to alter the previsous stability wall. This is hold masonry loading facades and inside structures partly.

Another is a parallel structure not to tilt or collapse in the middle of old timber structures. They are the very important to distribute loads, especially for addtional penthouse on the roof.

1. Piles & Columns St.Josveem is in front of the port, there are a lot of arranged timber piles embeded into the ground deeply. To support upper structure, the building, the head of piles are directly linked toward columns and masonry facades.

In the building, there are a lot of monumental details, a cast-iron column is one of them. Also columns are regulary arranged to distribute loads efficiently.

2. Garders, Beams & floorings Except steel beams in the middle of timber beams, all which are garders, beams, and floorings, are made by timber. These are light structures, so there are not enough to support extra loads for housing; they already lost stiffness.

3. Stability wall The most important structure is stability wall. Thatâ&#x20AC;&#x2122;s because there is the long length building, so two facade toward street and waterside should be tilt or collapse when stability wall is disappeared.

However, it is essential to make flexible space for changing from the warehouse to housing and for making housing units

4. Masonry load carrying facades Masonry facades have many monumental details, and they can distribute loads.

However, It is a really old building, so there are no longer stable structures; a lot of cracks tell a true.

St. Jobsveem has two different structural systems due to the building’s long shape and its program, warehouse. To make big, flexilble, and contiuous space to load, unload, and store something, the building’s major structure was adopted cast-iron columns filled by concrete. To make a light and strong structure, garders and beams, which is made by timber, The column has a groove to hold a timber beam horiztionally and link another column vertically.

To reinforce timber beams, I - shape iron beam was embedded between them, so people cannot see it.

Temporary stability beam* is to keep stability in order to build steelstairs in atrias during construction.

Building Methods In order to revitalize St. Jobsveem, it is necessary need to support and hold old structures by using temporary structures like supporting structures, temporary stability beams, and connections to prevent both old structures and supports from destroying during the period of construction.

Because there are more space and more strong structure people need to use the building as a multi-housing even though original structures themselves are still workable.

1. Steel framework for Atria Atriasâ&#x20AC;&#x2122; steel frameworks are alternation of the original stability wall not to tilt the building of collapse in the middle of floors. Three steel frameworks are directly connected facades and inner structures like columns, beams, and floorings. These keep perpendicular stability of structure.

2. Parallel stability structures After removed the stability wall to make flexible space for houseing units, additional need is emerged: How to reinforce floors. Original structures are not stiff anymore, though they are able to support some loads. Moreover this building should stand more loads than before.

From those reasons, Mei architecten used additional parallel coloumns (vertical structures) among atiras.

3. Additing torsion bars for decks To fill needs to use decks as a balcony and make atria without any destroy of decks, old garders behind facades are reinforced and new steel-concrete garders are partly insulted. New structures also support steel frameworks and glass facades.

4. Additional floors: penthouses After the former process to reinforce the old structure, penthouses on a roof was built with a light structure like a timber, a wooden plate, and an iron plate.

THE DESIGN OPTIONS Designing is a long process from first sketch to the best solution you think is possible. Between these two steps a lot of decisions are made which eventually leads to the final design. This also means that a different decision along the way can bring you to a whole different design.

This is why we will look at different design options to improve the design of Mei Architecten. This will include design options for the whole building as well as the construction, the facade and the parking. We will compare the design options with the design made by Mei Architecten and seek for the best solutions for St. Jobsveem.

DESIGN OPTION | 1 TECHNICAL STUDIES ST. JOBSVEEM Râ&#x20AC;&#x2122;DAM

Different treatment Mei Architecten chose to treat the appartments the same on the west and eastside. In our opinion they could have made something more out of it because there are big differences between these two sides: the appartments on the east have the view over the water and large balconies where the appartments on the west donâ&#x20AC;&#x2122;t have either. We think it is possible to even these sides out by moving the dividing line between the apartments. In this way, the appartments on the eastside will be slimmer but the appartments on the westside will have more facade surface and so we add a new quality be reducing an other. Now both sides will have different qualities instead of one side having them all.

DESIGN OPTION | 2 TECHNICAL STUDIES ST. JOBSVEEM R’DAM

Regaining the facade St. Jobsveem is a big renovation project which became more complexed when it was stated as monument. One of the statements of Mei Architecten was that they wanted to regain elements to keep the old warehouse look. But on the other hand they made three enormous openings on both facades.

We think this can be reduced to three atria that will only open up to one side. On the street facade you will only have one large opening and so the biggest part of the facade will we regain as it was. This thought fits more in the vision of ‘Monumentenzorg’.

DESIGN OPTION | 3 TECHNICAL STUDIES ST. JOBSVEEM Râ&#x20AC;&#x2122;DAM

Diversity As already came forward in Design Option 1 there is a big difference between the two sides.

In this design option all appartments have an eastside facade aswell as a westside facade and use the rue corridor as horizontal distribution.

In this option you donâ&#x20AC;&#x2122;t need corridors on all the floors which makes it possible to keep the atria more open. An other advantage is that more daylight will enter which makes the appartment a lot lighter and every appartment will have the view and the watersight, so all appartments are equal in quality.

DESIGN OPTION | 4: PARKING TECHNICAL STUDIES ST. JOBSVEEM Râ&#x20AC;&#x2122;DAM Residential function Vertical distribution Commercial areas Parking areas Long section of the building

Parking option: A very simple and useful alternative to the almost non-existent parking system, could be an automatic underground car parking system.

This way it would be possible to both favour the commercial value of the ground floor -as the Mei studio decided to do- and to give completion to the project, where the parking issue is almost not thought of.

Design option | 5: glass facade technical studies St. Jobsveem R’DAM

Filtered & distributed wind

Detail: Textile coated with plastic material and tensioned Polynet

Strong wind

Image: Facade system, Westravan, Utrecht

Glass facade 1: One example from Westraven, which is located in Utrecht, looks like rational approach to keep atria’s transparency and exchage air. However, this facade system is not attractive; First, atria space should become outer space for air-control and fire-proof regulation. Second reason is atria’s facade system requires strong structure against heavy wind and its facade’s long height. Those kinds of reason, I guess Mei architecten decided to use iron wires to hold glass plates.

Design option | 6: glass facade technical studies St. Jobsveem R’DAM

Image: Canary Wharf DLR Station, London

Glass facade 2: By using strong vertical iron beams with angled glass suites, The example of the different glass facade system at Canary Wharf DLR Station, London, show another apporach to make St. Jobsveem’s atria inside-outside space.

It is possible to keep sight outward because of its narrow structure and ventilate air simultaniously. Moreover, its cost to built is cheaper than St. jobsveem’s glass facade system; test, invention, and product costs for it should be spend more than this example. However, St. Jobsveem is located in front of a river with a strong wind, there is more possibility to break glasses or bend iron beams, so the flexibity of its structure is really important. And then, there are different scales between two buildings, so using iron wire is more adoptable to keep transparency.

Design option | 7: Construction of atria technical studies St. Jobsveem R’DAM

1. Destruction to build three atria

2. Buillding cast construction

3. Curing the concrete surface

4. Atrias based on SRC structure

Construction of atira: To adopt SRC, steel-reinforced concrete, it is able to reinforce St.jobsveem’s original structures and create atrias. This would be strong and stiff connection between old and new structure more than steel framework. But, building method of SRC is usually based on wet process, and means construction cost will increase; the cost for frame molds, labors, times, etcs. If dry process is adopted to make atria by SRC system, the connection among structures will not be more stiff than Steel Framework system.

Second problem is the SRC structure is heavier than light steel structure, it would be burden to old structure. Finally, SRC system has potential to spoil St.Jobsveem’s monumental structures becasues its materials are timbers, cast-irons, and bricks. From those kinds of reasons, Mei architecten’s decision to use steel framework is the most adopatable choice.
