This unusual construction the Brandhorst museum in Munich, Germany is a is a long, two-storey with a cellar, rectangular construction bordering a well higher, trapezium-shaped subdivision that widens to the north “ The 12,100m2 edifice was designed by Berlin-based designers Sauerbruch Hutton and cost a‚¬46m and ten old ages be aftering and was eventually opened on the 21st May 2009. “ 1 The edifice is clad in 36,000 ceramic rods in 23 different colorss arranged vertically over a horizontally striped, sheet metal tegument. Inside the museum the walls, along with the attractively crafted white walled galleries the flooring and stairway are constructed from light Danish oak that connect all three exhibition countries. “ The chief galleries are of course lit throughout – a hazardous scheme, and one that would dismay many conservators, since daytime has many tempers, some sort to pictures, some cruel. Yet here, someway, consistence has been maintained at the degree of the shows ; meanwhile, up above them, daytime is allowed to play its soft games among a complex system of near-invisible louvres. “ 2

Site Conditions – Question 2

Within this subdivision inquiry two asks me to place the context of the expected site conditions that will hold an impact on the solution to inquiry 3.

Salient Features Of The Brandhorst Museum... TOPICS SPECIFICALLY FOR YOU

Site Investigation & A ; Soil Investigation

When the development of the Brandhorst museum was foremost considered a site probe would hold taken topographic point to find precisely what the possible development site was made up of, site probes can convey to the surface any concealed dangers beneath that are n’t seeable to the bare oculus. Part of the site probe will besides be to transport out a dirt probe to find the suitableness of the site for the Brandhorst museum. The dirt probe will besides enable the designer to supply the right foundation design has he/she will cognize the type of undersoil. The dirt probe will be carried out by delving test cavities normally of around 3m in deepness to take dirt samples.

Expected Site Conditionss

Within this subdivision I will discourse the expected site conditions as listed below ;

Trees – saving orders

Water Table

Soil Types

Contamination

Land Remission

And the likely impact they will hold on the followers ;

Choice of foundation

Excavation

Soil Retention

Land Water Control

( See Appendix A – Expected Site Conditions and Impact )

I have made the undermentioned premises with respects to the development site for the Brandhorst Museum, Munich, Germany ;

The building site is a Green-Field site with no trees under the tree saving order the H2O tabular array is reasonably low with no environing grounds to turn out otherwise i.e. nearby rivers etcaˆ¦ although it is apparent that groundwater control will be required whilst unearthing due to the fact of holding to unearth deep to suit the cellar. The sub-soil content is dry sand/gravel with no marks of land remission.

Foundation System ( Substructure ) – Question 3

Within this subdivision I ‘m traveling to explicate the likely sequence of the engineering employed for the given foundation system for the Brandhorst museum, Munich, Germany.

Choice of Foundation

The pick of foundation for this undertaking will be a strengthened concrete strip foundation as the sub-soil is suited and stable plenty to back up such a foundation. The type of strip foundation most suited for the development I feel is the broad strip with strengthened concrete due to the fact of the burden of the construction will be comparatively high.

Excavation

Basement

The method of digging used for the cellar of the Brandhorst museum is the unfastened digging entire excavation, this method does necessitate a batch of site infinite but the development site for the Brandhorst museum is a reasonably significant size. The method of unfastened digging besides reduces the sum of impermanent support you require due to the beat-up side digging that must be at a safe angle of rest. The angle of rest for Gravel & A ; Dry sand is 40 grades

( See Figure 3.2.1 – Open Basement Excavation Illustration )

( See Figure 3.2.2 – Brandhorst Museum Basement with Skylight )

Foundations

As a consequence of the pick of foundation the pick of digging for the foundations will be a trench digging with perpendicular faces. Using this method will necessitate impermanent support as opposed to the trench digging with beat-up borders but will take up less infinite on site ; I feel this is indispensable as the digging for the cellar will take up a big sum of infinite.

( See Figure 3.2.3 – Deep/Wide Strip Foundation Example )

( See Figure 3.2.5 – Trench Excavation with Battered Side Illustration )

Figure 3.2.5 – Trench Excavation with Battered Side Illustration9

Basement Construction

The method used on the Brandhorst museum is the “ Retaining Wall and Raft Basement – this is the general format for cellar building and consists of a slab raft foundation which forms the cellar floor and helps to administer the structural tonss transmitted down the retaining walls ” 10

Most sites are suited for a cellar, but it is good pattern to committee a geotechnical study to guarantee site suitableness. Care should be taken if the study reveals a for good high H2O tabular array, a high chance of a perched H2O tabular array or if the site is in a inundation hazard country. These jobs would non govern out a cellar but are likely to increase building and sealing costs.

In some instances maps or a site study will demo that there are power overseas telegrams, cloacas, or mains pipes running through the country where the cellar is planned. These can frequently be moved, but in some instances the cost of making so may turn out prohibitive.

On Brownfield sites dirt contaminations and land gasses can show a job. Fortunately, some waterproofing systems can supply protection against both of these.

( See Figure 3.2.7 – Brandhorst Museum Basement Drawing )

Figure 3.2.6 – Retaining Wall and Raft Basement Illustration11

Figure 3.2.7 – Brandhorst Museum Basement Drawing12

Soil Retention

Impermanent support for all the trench digging walls are traveling to be required every bit good as the trench wall for the wall of the unfastened cellar digging apart from the side that will be a beat-up side digging that must be at a safe angle of rest.

Foundation Excavation Temporary Support

The impermanent support used for the trenches excavated for the foundations “ is called timbering irrespective of the existent stuffs used, if the sides of the digging are wholly covered with timbering it is known as a close timbering whereas any signifier of partial covering is called unfastened timbering, An equal supply of lumber or other suited stuff must be available and used to forestall danger to any individual employed in an digging from a autumn or dislodgment of stuffs organizing the sides of an digging. “ 13

( See Figure 3.3.1 – Timbering Example )

Basement Excavation Temporary Support

The impermanent support traveling to be used for the digging of the cellar is traveling to be in the signifier of a caisson “ These are impermanent enclosures installed in dirt or H2O to forestall the immersion of dirt and/or H2O into the on the job country with the caisson. They are normally constructed from meshing steel sheet hemorrhoids which are appropriately braced or tied back with land ground tackles. Alternatively a caisson can be installed utilizing any structural stuff which fulfils the needed map. “ 14

( See Figure 3.3.2 – Cofferdam Example )

Figure 3.3.1 – Timbering Example15

Figure 3.3.2 – Caisson Example16

Groundwater Control

Within this subdivision I ‘m traveling to discourse the groundwater control techniques put in topographic point for the digging for both the cellar building and the foundation trenches.

Basement Construction Groundwater Control

Equally good as support for the digging for the cellar building the caisson will be used in order to forestall H2O immersion whilst building of the cellar is carried out these can besides be used in concurrence with a pump if required as elaborate below.

Foundation Trench Groundwater Control

A simple pump method will be used for the groundwater control for the trench digging, there will be a sump excavated beyond and below trench digging and the H2O will be pumped from the sump inside the trench therefore enabling the workers to temporarily take down the H2O tabular array. As antecedently mentioned you can utilize a sump pump in concurrence with a caisson from groundwater control which is a similar sort of footing merely for the basement digging two pumps are required both methods will be illustrated within this study.
