Diaphragm wall: Construction and DesignUmer Farooq
Diaphragm walls are concrete or reinforced concrete walls constructed in slurry-supported, open trenches below existing ground.
Concrete is placed using the Tremie installation method or by installing pre-cast concrete panels (known as a pre-cast diaphragm wall). Diaphragm walls can be constructed to depths of 150 meters and to widths of 0.5 to 1.50 meters.
Top-down construction method as the name implies, is a construction method, which builds the permanent structure members of the basement along with the excavation from the top to the bottom. Top-down method is mainly used for two types of urban structures, tall buildings with deep basements and underground structures such as car parks, underpasses and subway stations.

Diaphragm walls are underground structural elements.
It is an in-situ reinforced concrete structure that is constructed panel by panel.
Diaphragm walls are ideal for soft clays and loose sands below the water table where there is a need to control lateral movements.

Building construction is an ancient human activity. It began with the purely functional need for a controlled environment to moderate the effects of climate. Constructed shelters were one means by which human beings were able to adapt themselves to a wide variety of climates and become a global species

Pile foundation is that type of deep foundation in which the loads are taken to a low level by means of vertical members which may be of timber, concrete or steel.
GFRG/ Rapid wall is load bearing pre-fabricated walling panel. This is suitable for rapid mass scale building construction was originally developed and used since 1990 in Australia. Currently, in India GFRG Wall Panels are manufactured at FACT-RCF Building Products Limited (FRBL) at Ambalamedu, Kochi, Kerala. These presentation contains all in one information about GFRG Panel like uses of GFRG Panels, manufacturing of GFRG Panels at FRBL, stepwise construction of GFRG building and finally a comparison of GFRG building and a conventional building.

The intersection of railway track and the road at the same level is referred to as a level crossing. In the urban areas the level crossing is generally monitored by qualified railway personnel who monitor the train movement and close the level crossing gate to stop the interfering road traffic but such closing of gates leads to congestion in road traffic and also causes loss of time to road users. Road under bridge and road over the bridge are considered as solutions for avoiding level crossings of roads and railway track.

The Austrian Standards Institute published ÖNORM B 2203-1 “Underground Works – Works contract, Part 1: Cyclic driving (conventional tunnelling)” in 2001.
This Austrian Standard includes particular directives for tendering procedures, preparation of the bid and terms of contract for the execution of conventional tunnelling called “New Austrian Tunnelling Method (NATM)”.
In addition to the Standard the Austrian Society for Geomechanics in 2011 published the document “The Austrian Practice of NATM Tunnelling Contracts” which describes the application of the Standard in detail with respect to the NATM. The main chapters of the document are
Tendering and Costing as well as Construction and Payment with information in detail about
time-dependent costs,
tunnelling interruptions
, tunnel classes
, difficulties due to water ingress
, over-excavation, excess concrete
, selection of supporting measures and classifying tunnelling
. Examples describing the method are presented in an annex
. The Austrian Society for Geomechanics recommends the download of this document in addition to the Austrian Standard ÖNORM B 2203-1:2001. The document “The Austrian Practice of NATM Tunnelling Contracts” with its annex is free of charge. Learn more: http://www.as-institute.at/en/standards/downloads.html

EXCAVATION FOR FOUNDATION - Methods & Temporary Earth Retaining StructuresShivananda Roy
Generally excavation means to loosen and take out materials leaving space above or below ground. Sometimes in civil engineering term earthwork is used which include back-filling with new or original materials to voids, spreading and leveling over an area.
2. Why Top Down Construction
Required
► Distance between Boundary wall of Adjacent Existing
Building and Building Line for New Building is too close and
the depth of excavation is more than 6 meter and
possibility of collapse the soil is higher during excavation.
► Using Top Down Construction more Building and Basement
Area can use. Suitable for two or more basement.
► The first base slab level slab will act in such area as a strut
member and the Retaining wall panels will not allow
collapse of soil.
► Water table is too high and difficult to cast Retaining wall,
Diaphragm wall or Continuous Pile can use as a Retaining
wall.
3. METHODOLOGY OF TOP DOWN
CONSTRUCTION
1. Setting out for alignment of bore cast in situ of
piles .
2. Bore Cast in Situ Piles to be cast and dowels bar
to be kept for Retaining wall panels. The center
of piles and Retaining wall panels center line to
be kept in same line. The Diameter of Piles
preferred 600 mm, distance between two piles
center to center preferred 3.33 meters (Suit for
C/C distance of Columns), Depth of Piles to be
confirmed by Structural Consultants.
3. Touching Piles can use as a Retaining wall with
supporting arrangement during Excavation.
4. If area of Basement is more and Span is less
Diaphragm wall can be use as a Retaining wall.
4.
5. 3. Instead of Column C1 to Column C8,Bore
cast in Situ piles to be cast with dowel
bars for different level slab and
connecting Beams, The Diameter of Piles
(suit as per Columns size),
Reinforcement details (with dowels for
Retaining wall and different level slabs
and Beam), Depth of Piles to be
confirmed by Structural Consultants.
6. 4. Excavation to be done around 2 meter
depth and retaining wall panels to be
cast in stages with dowels bars with
adjacent piles and dowel bars for next
Retaining wall panel to be kept .if soil
between piles collapsed soil nails with
wire mesh to be kept on earth side to
retain the same. Retaining wall panels to
be cast with dowels up to the first base
slab bottom.
7.
8. 5. Dressing and compaction of soil to be
done for PCC bed for casting of first base
slab. 50mm PCC (M15 Grade) to be
done, the top levels of PCC to be keep
the base slab level bottom. For beams
excavation to be done in same alignment
and dimensions as required and PCC or
brick work to be done as per beam
dimensions in Vertical face.
9.
10. 6. After PCC 3mm ply to be laid on PCC
Surface and PVC sheet to be nailed with
PCC surface so surface of PCC and
Surface of Slab Concrete will separate.
7. Reinforcement to be completed as per
drawings, for beams dowel bar to be
used from Cast in Situ Piles. Dowel bars
to be keep for adjacent slabs for Bottom
Up Construction.
11.
12. 8. Concreting of Slab and Beam to be
completed.
9. After 14 days of Concreting, PCC below
slab to be break/removed excavation to
be continued and retaining wall panels to
be cast. Till final level of excavation.
10 Waterproofing to be done and base slab
to be cast with dowels from Cast in Situ
Piles.
11.Jacketing of Columns to be done if
required.
