Thank you for all the reply and r13 for the link.
I read a manual "Pile Design and Construction Practice by Tomlinson". stated:
“The length to diameter ratio of the rock socket is an important factor in the consideration of the bearing capacity of the pile in shaft friction and there is no point...
I would appreciate it if someone could provide me a reference with figures showing the influence zone of friction bored pile socketed in rock. Thank you.
Suppose a number of columns in a row are to be supported on a soil of such low bearing strength, that separate bases if provided would overlap,a practical solution would be to provide a column footing to support all the columns of the row. such a footing is called a "STRIP FOOTING"
The foundation of the new building is a strip footing/foundation.....longitudinal and transverse direction(longitudinal dir-6 bays and transverse dir-3 bays).... The section detail that I am showing is from a longitudinal strip footing. The depth required for the footing is 700mm which is not...
Hi,
The strip foundation of my new structure overlies in the foundation of an existing strip foundation. I attached a file of my propose detail design.
I would like to ask for a second opinion for my design proposal. Any reference books I could refer to regarding connection of new foundation to...
Ron: Actually for a year, I only experieced 7days of rain. The temperature during summer is about 45C-50C.
Steve & a2mfk: The max. span of the hollowcore slab is only 4m. Before placement, we will check the bottom level of the hollowcore slab for deflection.
Also, we haven't find any...

Previous Project/116 houses: 0.5m soil improvement
Geotech 1st proposal remove 3m depth of loose soil but costly.

Mccoy: For this testing the result will be for the predicted long term settlement?
BigH: In our previous project the contractor proposes #1. Before backfill of 0.5m good material we compacted the site using heavy vibrator roller.
The Geotech calculation for the settlement is only for the...
We already instructed the contractor to remove all the roof topping and to replace it.
Our provisions:
Layer 1: Sprayed foam of polyurethane, min. 50mmthickness
Layer 2: Liquid protective membrane applied to a minimum dry film thicknes of 800microns.
Layer 3: Protective layer of 100grams/sq. m...
Hi, I have a problem in one of our apartment project it is about 10 to 15years old. The roof topping have many cracked with a 10 to 20mm vertical movement. In one portion of the roof water leaks, the rain water pass through the adjoining joint of the hollowcore slab.
Our preliminary assessment...
Mccoy & oldestguy:
I will discuss with the Geotech regarding the compressibility and shear strength of the soil...
We have one project same Geotech advise to remove the 3m depth loose soil but since it is a mass housing project the mentioned method is costly and the project is still pending...
Additional information: These 250 houses have a raft foundation. Top level of foundation is -0.4m below the proposed ground level. The project site is a reclaimed area.
Thanks for the reply:
@Ron: I inspected some of the previous projects wherein some of the houses tilted about 60mm to 70mm due...
Hello to all...I would like to ask regarding the very silty soil found in our project site if it is ok or not to remove this unsuitable material before contructing 250nos. three storey houses(ground floor area: 8m x 13m).
As per soil investigation report the sieve analysis for 3 out of 6...
