Architect’s requirements

Concrete faces that are subject to special requirements regarding appearance (see DIN 18217) – in short, “archi-tectural surfaces” – are generally referred to as “fair-faced concrete”. The description of fair-faced concrete is not always entirely clear-cut, and various different definitions are given for it in the normative literature. Essentially, fair-faced concrete is a part of the structure that is intended to remain on view after completion. Fair-faced concrete structures tend to be modern, “one-of-a-kind” exemplars where a free and creative approach has been taken with regard to the shapes and surfaces.

The requirements made by the client and its architect(s) will tend to include the following:

a) Emphasising the uniqueness of the structure. In this respect, in-situ concrete offers a certain degree of archi-tectural freedom.

b) Ensuring that the structure is functionally appropriate and can be utilised in the manner intended

c) Having free scope to choose the desired surface design (in terms of grid patterns, joints and surface texture)

d) Supporting the development of advanced, unique structures with the creative freedom to shape both forms and perspectives

When it comes to planning a project, functionality and optimum space utilisation are decisively important – but so too are the surfaces, and the visual impact that these surfaces have. The focus is thus on the appearance that the architect wishes to impart to the concrete surfaces (the “architect’s wishes”).

If the architect’s ideas are to be put into effect success-fully, the fair-faced concrete team will need to have discussed all the issues involved very thoroughly. Having clearly defined responsibilities in the fair-faced concrete process is a key component making for successful im-plementation. Fair-faced concrete means teamwork! This reference brochure is intended to help bring about a clear formulation of the architect’s objectives.

Structuring of the concrete surface

Before starting your forming preparations for tackling dif-ficult fair-faced concrete surfaces, you should address the following points:

• valid(i.e.approved)planningdocuments,preferablyindigital form

• whereverpossible,buildingshellplans(showingonlythe load-bearing walls and floor-slabs)

• establishingexactlywhichsurfacesaretobeexecutedin fair-faced concrete

• definingtheformworkpatternonthebasisofthe tender documents

• agreeingtheelevationplanswithlayoutsandsections(interruptions in the architectural surfaces due to adjacent walls and floor-slabs)

• takingaccountoffixtureswhichmayaffectthearchitec-tural surfaces (lighting, tubes etc. ...)

• decidingupontheconstructionjoints,inliaisonwiththestructural designer

Joints

Walls

In formwork-engineering terms, there are several different ways of creating the joints that are required by the planner and the structural designer, and/or that are necessary from the workflow point of view.

These different types of joint each leave a different imprint in the concrete. Particular at-tention must be paid to construction joints, and to how these are dealt with in fair-faced concrete surfaces.The following points will need to be discussed with the planner and structural designer regarding the location and arrangement of construction joints:

Will the corners and wall junctions have to be formed as one single casting section, or can the walls be broken down into separate sections?

Texture of the concrete surface

The formwork is an important instrument for shaping and designing concrete surfaces. It is the formwork that im-parts the final shape to the concrete. The point of paying timely attention to the question of which formwork, form-ply and concrete to choose (“timely” meaning before the project is put out to tender) is to make matters clearer for all parties involved. Such measures may also make it possible to utilise rental formwork. However, the main influence on the appearance of the concrete surface is the concrete itself, and how it is utilised, and the release-agent that is chosen.

The following overview (source: ÖVBB Guideline “Formed concrete surfaces”, November 2009) points out the inter-relation between the surface of the form-facing and the surface appearance of the concrete, and possible effects.

1) Wood is a natural material in which – initially – the wood sugar content is unevenly distributed. To prevent dust formation and colour-shade differ-ences the first few times a sheet is used, pre-treat it with cement slurry or by using it first on less important building components. In dry weather, strongly absorbent types of form-ply intended for forming fair-faced concrete must be pre-moistened before pouring.

2) Allowance must be made for shape deviation caused by boards shrinking and swelling.

3) The absorbency of form-ply types 1 to 5 changes depending on the water saturation and the number of times the sheet has been re-used.

4) The non-absorbent properties of form-ply types 6 to 9 remain unchanged.

5) Excess release-agent must be squeegeed or wiped off.

Form-facing

The form-facing is the part of the formwork with which the visual effect of the fair-faced concrete surface (i.e. its texture and tint) can be influenced. These two factors can be changed by using different types of form-facing. The form-facings are outlined below in categories ranging from strongly absorbent (boards) to non-absorbent (plastic, steel etc.

Formwork systems and their attributes

When the fair-faced concrete surfaces are being planned and put out to tender, the choice of formwork system is crucial, for both economic and technical reasons. The choice made here decides whether system formwork (framed or timber-beam formwork) can be used for the structure, or whether project-specific custom solutions will be required.

Impact of the formwork on the surface appearance:In general, three groups of formwork are differentiated; these may be used both for walls (straight/curved walls, columns) and for floor-slabs:

• system-basedframedformwork• system-basedtimber-beamformwork• customtimber-beamformwork

The high usage intensity, flexible handling, short forming-times, rapid delivery times and rentability of pre-assembled framed and timber-beam formworks make them extremely cost-effective. The big advantage of project-specific custom solutions is their complete adaptation to the geometry and surface of the structure to be formed. Factory pre-assembly of the formwork elements permits short forming-times, but requires longer lead-times for the design, planning and as-sembly work, as well as calling for very special care in transit.

More on this from Page 24 onward.

21

Edges

Corners and edges are usually not cast with sharp edges, because these can easily be damaged when the formwork is struck, and in everyday use.

Any triangular ledges used in the casting of fair-faced con-crete must be suitable for the type of form-ply being used, in order to prevent colour differences caused by different absorption behaviours:

•WithFramaxXlife/Alu-FramaxXlifeframedformwork,PVC triangular ledges (chamfers) should be used (i.e. a non-absorbent triangular ledge with a non-absorbent form-ply)

Design details

•Timbertriangularledgesshouldbeusedonformworkfaced with with 3-ply sheets or boards (i.e. an absorbent triangular ledge with an absorbent form-ply)

To achieve clean sharp-edged corners, the formwork must be sealed by other means than triangular ledges, in order to prevent seepage of fine-grained mortar. Sharp-edged cor-ners can best be achieved with Large-area formwork Top 50.

23

Costing calculations

The aim here is to obtain certainty regarding the likely formwork costs. In principle, it may be said that it is the architectural ideas which decide.

Factors influencing the formwork costs:• formworkrental,formworkplanning,joints,edgesand

sealings• purchasingform-facing,assemblyanddismantling,

storage and care• otherpurchasedcomponents,transportandhandling,

corrective maintenance of formwork

Results and appraisal

When areas of fair-faced concrete are given acceptance inspection and appraisal, the main emphasis is placed on evaluating the overall impression of a structure or part of a structure when viewed from a reasonable distance. To the extent permitted by the limitations that are typical of the type of construction and the type of materials used, the visible surfaces should achieve a harmonious overall appearance. Any chance irregularities are technology-specific and are characteristic of fair-faced concrete.

Formwork InstructorsThe Doka Formwork Instructor is a specially trained and experienced practitioner who explains to your crew how to use the formwork effectively and safely. As well as the Formwork Instructors, Doka offers many other onsite services such as onsite formwork erection and consult-ing by fair-faced concrete experts. Especially when tough specifications are made regarding the concrete finish, it is more important than ever to ensure that the forming opera-tions are performed correctly and without any makeshift improvisations.

Formwork utilisation plansThorough, accurate planning is the basis for fast, safe forming operations. Doka planning is carried out on an engineering basis in accordance with the applicable Standards and rules. To simplify implementation, Doka can draw up bills of materials which will give you a good overview of all the products and services. If you wish, Doka experts will be pleased to draw up cycle plans for you, so that you can make optimised use of the required quantity of formwork, and also elevation plans showing the spacing of form-ties and the joint grid.

Structure modellingTo give you a better visualisation of complex geometries, Doka technicians can model the structure for you.

“Ready-to-Use” serviceDoka system formwork covers wide areas of formwork applications. The special requirements of fair-faced con-crete projects often call for special measures, however. This is where the Doka “Ready-to-Use” Service comes in, “tailor-making” custom formwork units for you. Each such custom formwork is very precisely crafted to ensure accurate assembly on the site.

CleaningAccumulated dirt is removed from the formwork using special equipment and industrialised procedures so as to fulfil the Doka quality standards. Depending on the degree of soiling and the product, the cleaning operation will comprise both wet cleaning, mechanical cleaning and special cleaning.

Reconditioning ServiceDoka rental formwork and client-owned Doka equipment is cleaned and overhauled here, to Doka quality standards, by the Doka Reconditioning Service. This lengthens its serv-ice life and means that on your next forming assignment, you can be sure of having perfectly functioning formwork equipment – always a precondition for top-quality concreting results.

The architecture firm of Krischanitz was behind this model housing development, consisting of 10 apartment buildings on an 8000 m² plot on the outskirts of Vienna. 9 noted architects from Austria, Germany and Switzerland were each invited to design one of the buildings.

All the buildings were required to be constructed solely from concrete, to demonstrate the huge variety of shapes and forms that are possible with this material.

Together with the client, the architecture firm of Denzer & Poensgen from Cologne here devised a striking spatial and residential concept: With around 470 m² of resi-dential space on 3 levels, the building – which is almost entirely in fair-

faced concrete – alludes to the legacy of Roman building culture which may be found throughout the historic city of Trier. Its clearly organised design features paths, patios, passageways, indoor and outdoor spaces, with the re-sult that living in this house is a truly unique experience.

A microcosm of a small ancient town, in fact: closed to the outside, and then gradually opening itself to residents and visitors alike as one moves inwards, culmi-nating in an architecturally styled atrium with a water basin as an oasis of green at the heart of the building.

floor plateau and the “box”. Two retaining walls running in parallel with the hillside merge with the basement and the terrace to form a stone plinth as part of the modelled terrain. On this pla-teau is the living-room, with a semi-openplan kitchen. The room-high glazed areas on

the southern and northern sides set the boundaries of the interior, although in visual terms the living-room extends out to encompass the entire area of the plateau. This offers unobstructed views out onto the surround-ing countryside and the hills of the Vienna Woods.

Situated at a busy cross-roads, this four-storey structure was designed in dark grey fair-faced concrete. It includes a car-park, business premises and offices on approx. 8000 m2 of floor-space.

The use of Doka 3-SO three-ply sheets mounted on Framax Xlife led to the horizontally orientated appearance pattern of the fair-faced concrete facade.In order to match the tie-hole pattern to the format

of the 3-SO sheets, timber closures were fitted between the panels to allow more flexible spacing of the form-ties. Around the windows, the construction joints were emphasised with trapezoidal strips.

The architect specified that the form-tie and joint pattern was to be kept as uniform as possible across the entire area of these walls. To meet this specification, only one

single size of panel (Framax Xlife 240x330) was used in the forming operations.

For the second wall casting section, the form-tie points of the first casting section were used as the suspen-sion points for the platform. This enabled the formwork pattern to be retained in this area as well. The fair-faced concrete team was a model of successful co-operation, enabling superb results to be achieved.

Special featureConstantly varying longitudinal and transverse gradients; all formwork-sets pre-assembled by the Doka Ready-to-Use Service

The system developed by engineering consultants Anselment makes it pos-sible to build basement car-parks, multi-storey car parks and car-parking decks with plenty of use-able space that is unob-structed by columns. The complex shaping of the coffered haunch plates, consisting of longitudinal and transversal haunches, makes very high demands indeed of the formwork-makers. The parking deck at the District Clinic in Biberach was built on top of an existing car-parking area and merges with the contours of a hill.

Every slab span and every haunch becomes narrower

in the longitudinal direction, and the column cross-sec-tions decrease from 1.30 m to 1.20 m. As the downhill gradient of each casting sec-tion increased from 0.40% to 5.15%, every single formwork element had its own separate

longitudinal and transverse gradient. In each case, the shape of the skewed ply-wood face was dictated by precision-cut profiled timber formers mounted on Doka-matic table grilles.

The concept for the Liaunig private museum comprises 4 strikingly distinctive building members. It encompasses a 600 m² viewable storage area, the 160 m long main exhibition corridor, the 500 m² room for graphics and a separate room (approx. 350 m²) for the gold collec-tion. The main focus of the formwork planning work was on the “fair-faced concrete tunnel” with its length of 160 m. For this, the timber-beam formwork elements were hung from a reposi-tionable construction. This made it possible to travel the 10.40 m long and over 7 m high “formwork curtains” relatively easily from one casting section to the next.

Special featureWall with 30° rearward inclination; up to 7 m high

Using Doka formwork, contractors Hilti & Jehle achieved superb fair-faced concrete on this project to remodel the church forecourt and extend the cemetery in the Austrian town of Sölden. Planned by architect Raimund Rainer and commissioned by the local authority, the project was implemented to the client’s complete satisfaction.

The limited space avail-able in the centre of the town and the high quality specifications laid down by the client presented a major challenge to the planning architect and the contractors, and to Doka as the formwork supplier.

In view of the stringent qual-ity specifications, this project called for close collaboration between the architect (Rain-er), the construction super-visor of the municipality of Sölden, the contractors Hilti & Jehle (Ried), the Rödlach structural design office (Telfs) and the formwork special-ist Doka, in order to achieve optimum concreting results.

In this connection it was par-ticularly important to define a concrete appearance – with uniform spacing of the joints and form-ties – that not only fulfilled the aesthetic de-mands but also took account of formwork-technology practicalities.

after the concentration camp was liberated, the Memorial is being extended – with an elongated and gently slop-

ing documentation centre constructed almost entirely of fair-faced concrete on both inside and out.

The ideas and planning work for this exhibition building were supplied by architects KSP Engel und Zimmermann of Braunschweig. They make very deliberate and con-scious use of concrete as a powerful design element in its own right. The result is a 195 m long, 18 m wide and up to 12 m high two-storey fair-faced concrete struc-ture with a good 1500 m² of exhibition space and archive rooms. The roof area runs nearly horizontally, while the floor rises by around 2.0 m over the entire length.

Special featureAccentuated (ribbed) joints

With around 15,000 m² of exhibition space, Ger-many’s biggest museum of modern art opens itself

towards the city-centre as a light and airy conserva-tory on the south side of the building, while the northern

side offers an unobstructed view of the older “Alte” and “Neue” Pinakothek galler-ies. The fair-faced concrete facade was constructed as a thin-walled facing in CIP concrete with a defined 5.6 m x 2.6 m joint grid, projecting horizontal and vertical ribs and sharp edges.

cratically shaped supporting cores, with the swimming pool sunk into the middle of it. Stringent fair-faced con-crete specifications, complex geometries and non-tied sup-porting cores – these were among the challenges which the various Doka formwork systems had to address.

Doka 3-SO three-ply sheets also stand out for their very great dimensional stability and high numbers of re-use cycles. At the Kaltern lido, their natural wood structure is being deliberately used as an architectural design element.

Form-facingXlife sheet, film-coatedmulti-ply formwork sheet

The use of Large-area formwork Top 50 made it possible to produce a neat formwork and tie-hole pattern on the visually exposed surfaces. On nar-rower sections of wall, the form-ties were located outside the concrete. On wider sections of wall, the form-tie points were ar-ranged in such a way that they fit in seamlessly with the overall concept.

Hungerburg Funicular, River Inn Bridge

Innsbruck’s new Hungerburg Funicular makes it possible to take a ride directly from the city centre all the way up to 2200 m above sea level.

Two existing gondola cable-ways were renovated and adapted, and linked to the city centre by a new funicular railway. A central architec-tural challenge of this project was the diagonal crossing of the River Inn in the heart of Innsbruck. The steel con-struction of the bridge is carried on cables hung from two 33 m tall pylons. The

pylons are inclined against the direction of pull and have a curved cross-section which varies across the entire height of each pylon. For each height-section, the Doka “Ready-to-Use” Service sup-plied separate tailor-made shaping-timber boxes.

The overall formwork con-cept was rounded off by an ingenious system for the working platform in each of the height-sections.

FormworkWall formwork FF20


The equipment used here included Wall formwork FF20 and a pre-assembled steel-waling construction. The exact shape adapta-tion was achieved using

shaping-timber boxes pre-assembled by the “Ready-to-Use” service. A particular challenge here was the com-plex geometry in the “kink” on the spherical surface, with

its relatively tight radii. The surface of the pier was sand-blasted to give the concrete a matt appearance.

The City Tunnel is a twin-tube railway tunnel linking Leipzig’s main railway station to the Bayerischer Bahnhof station. The 197 m long Bay-erischer Bahnhof itself has 11.30 m high fair-faced con-

crete walls. The suspension points for the climbing form-work are integrated into the form-tie pattern and given a similar appearance to the form-tie points. The bracing struts for the stairwells are

placed crossways across the overhead space. Daylighting is provided by a large central opening in the roof of the station.

Form-facingTexture sheet 3-SO

A new motorway junction at St. Gallen-Winkeln also involved the construction of 1770 m of retaining wall. The contracting JV of ARGE Winkeln carried out the concreting works for this structure using 10 sets of Large-area formwork Top 50. Each of

these sets of formwork was 8.1 m long. Some extremely attractive concrete results were achieved. The forms were faced with Doka 3-SO textured formwork sheets. Despite the large number of casting sections, these delivered superb concrete surfaces.

a distinctive geometry. The large width of the sidewalk kerbs made it impossible to use a standard overslung edge-kerb forming wagon here. Also, the very limited

clearance between the bridge and the overhead contact line meant that a standard underslung edge-kerb forming wagon could not be used either. Instead, a custom solution based on Doka’s steel-composite-bridge system had to be devised.

Viaduc de Verrières

The 5 piers of this motor-way viaduct near Verrières are characterised by their unusual geometrical shape.

While the three shorter piers rise in a uniformly tapering conical shape, the two larger ones grow out of a 40 m high parabolic shaft. This parabolic pro-file is visually accentuated by its projecting haunch.
