K Riangsorn,
Now that we got the car park levels from TBP , as we discuss last Tuesday’s weekly meeting can you now check to see if we can construct the new concrete pavement 150 mm thick directly on top of the existing car park paving by adjusting the TBP finished levels if necessary.If need be we can do some trial holes.
This will give VE savings on demolition costs , sand and crushed rock.
Also please review the drainage/gutters as we discuss to see if we can reduce the numbers.
Please overlay the existing CB Survey car park drawing with the TBP new car park drawing so we can see the extent of the above possible VE savings.
Please let us know early next week so we can prepare any VE costing for our budget which we have to present to BTS the following week.
Regards,
Marvyn
