DAMBAI BRIDGE PROGRESS AS ON 26 FEB 2015

Major works done, getting ready to install the RHS pier to abutment short concrete beams 5 in number by backfilling behind the RH abutment.

On the LHS, I think the LH side deck is ready for concreting.

 End of the LHS abutment to pier bridge deck.  Note they used polystyrene as part of the formwork. I ask the workers if the white stuff will remain there after the concrete has matured. They seems to think so as they would be really below the bridge.  The planks and plywood can be removed but the polystyrene ??

On the RHS, one excavator is used to fill the road with gravels.  On this last pic, the large boulders found here were left underground, just filled over with these stones.  No problems with that. Also they started installing the place markers for the rubber bearings on top of abutment pile cap for each of the short RHS rc beams.

DAMBAI BRIDGE PROGRESS AS ON 17 FEB 2015

Progress seems slow from the public opinion because the traffic jam is getting worse along this road everyday.

For the contractor, the progress is slow but steady, at least there was not stop work except on public holidays.

 A sorry sight for the slow death of Bambangan tree,  the roots cannot even get any rain water.

 Behind the right abutment. There is no need to even remove that in-situ boulder because I bet that will only give additional strength to the road pavement to be filled with gravels later.
Note: the rubber bearings not installed yet, only the position markers and grout were prepared. Installation of the 5 short reinforce beams here are pending, maybe the completion of the left bank side.

 View from the RHS bank.  The RH pier and the LH bridge slab under construction at the other side.

 Another view showing what are under the bridge and the safety fence built with wall claddings, fixed on top of the old bridge railings.

 LHS showing workers temporary quarters and earthworks or the leftover of the temporary earthworks to access to the bottom of river.

 Note again that the bridge deck is sloping downstream, to ensure there will be no ponding on the bridge deck.

Workers installing the rebars for the bridge concrete safety wall.

I bet a car crashing onto that wall will not dent that wall at all, but a heavy truck might still fall over the bridge, just like in the movies??  he he

DAMBAI BRIDGE PROGRESS AS SEEN ON 5 FEBRUARY 2015

Hi loyal readers. Apologies my blog has been a bit behind time due to constraints but here goes.
Photo paints a thousand words so here are the reports for you to enjoy.

 To my good friend Emmanuel, the two pics above shows workers installing what seems to be 16mm diam steel reinforcing bars across the 5 rf concrete beams with plywood underneath to support the pouring of concrete for the bridge deck slab.

 The midspan prestressed beams are still waiting at the nearby yard waiting to be installed, definitely after completion of the abutment-pier spans first.

And the poor Bambangan tree is slowly dying from thirst.

 View of the ends of the rf concrete beams at the left hand side of the bridge. Shows formworks, falseworks and the abutment concrete on which the 5 beams are placed supported by the rubber bearings.

And the contractor also installed safety fence running over the railings of the old bridge.
Also preventing the public to see the progress from their cars now.  He he
