Fabrication of Prestressed Concrete Beam near the site 16 to 20th March 2014

The road reserve site infront of Mr Majawin's house was levelled with road quality crusher run and used as the fabrication site of the 30 m long prestressed concrete beam for the new bridge.
The bottom width is 660mm forming the lower flange, while the top is 410 mm.  Forgot to note down the thickness of web.
The overall depth of beam is about 2 m, while the designed weight is 45.4 tons using grade 50Mpa concrete. There are three strands of steel prestressing tendons of 15.2mm diam to be placed at the lower half. More photos will be taken once these are placed into the beams.
For the time being the workers are only preparing the forms and the rebars on site as per below.

STAGING and Construction Area for the Post Stressed One span Concrete Beam

The bore piling machines and cranes have long been demobilsed from site, athough the supervisor told me they will come back when the old bridge is removed and a new one constructed.

So JKR then reclaimed with clay and topped with road quality crusher runs the approach to the bridge as staging area for the concrete beam.
On 6th March 2014, they have started preparing the form-work support as shown in the photo below:-

Then they discovered that the foreground part as shown above is too low, not level, so they removed all these timber, filled the area with more crusher run and repeat the construction of the timber base for the concrete beam formwork.

Photos taken as on 13th March are as below:

So this was reconstructed.
Well I got this info from the workers themselves.

And at the same time the Majawin Bambangan tree is also very sad that her root area have been taken over and soon she will have to be chopped down.  So she protested by giving out the most beautiful red flowers for fruits. Although I am very much doubtful if the flowers will eventually produced fruits due to the very dry season for the last 4 weeks and even if it rains, the moisture no cannot reach the roots of the tree any more due to the impervious clay layer.

This type of tree needs to grow at least 15 years before it can bear fruits..Now all of us have to say goodbye to the ole Bambangan tree of which the fruits can be turned to pickled fruits or eaten like a mango if the species is the sweet type.

Meanwhile, the workers prepare the top of the giant bored pile for preparation of pile cap for the bridge.
