Dear all
I would like to know from your experience the number of hours you put in to design an excavation project (less than 20m) assuming you have all geotechnical data, lab tests, and loads ready.
thanks
I am designing a pile foundation to support 8000 kN axial load + 4000 kN lateral load + 600 kN eccentricity moment.
Piles are 1m in diameter and 23 meters deep
Soil profile mostly clay: first 10 meters Su = 80kpa and the rest Su = 200 kpa and groundwater level at the surface;
From analysis...
Dear all
I am designing a pile foundation for a new building. the columns are closely spaced so I decided to place them on a single pile cap with a depth of about 1 meter, each column will transfer the load to the individual pile. The pile cap will also be connected with ground beams.
Is...
Axial loads that go up to 2500 kN
25mm settlement required
SPT is not accurate in clay, still, clay parameters such as Su were obtained from SPT and PI.
The building is in the same area, but the building owner already complained about visual cracks which the owner want to avoid.
Yes, the procedure is unusual.
Well, the design firm mentioned that they knew well the area reason why they were confident that the soil is dense sand.
The owner did not have an engineer on the owner's side at the time project was being discussed, this was done later after project drawings...
Hi
(1) The contract required the foundation to be defined after soil investigation.
(2) The designer ignores it and proceeds with a shallow foundation and drawings were produced.
(3) Geotech was hired and requested Geotech investigation turn out piles are required.
(4) Designer requested...
Hi guys
Thanks for the feedback, the client's position is that in case the designer fails to comply with the contract condition, we will hire another Geotech firm to finish the design since we have retained part of the total amount of the design fee which will be used for payment.
He act...

No one agreed with the shallow foundations solution. It was the designer alone decision. If this was found during construction, the client would probably suffer more aggravated costs with delays etc...
A detailed shallow foundation drawing was prepared by the structural engineer. There was no analysis of shallow foundation e.g. settlement etc...
Shallow foundation not yet constructed since we decided to stop until piles are designed
In terms of cost, the client has no problem paying for...
Hi dik
The was no EOR when the decision was made.
I only came to take this job after decisions were already in place by the designer mostly.
A nearby building foundation was also designed on a shallow foundation but also without any soil report. The building owner complained about wall cracks...
The client was responsible for executing the geo investigation BUT the designer/structural engineer was confident that they knew the site ground condition and advised the employer to discard the investigation until I start working for the client and immediately order the investigation. The...
To clarify
I am the owner/client representative for this project. Our contract required that a soil investigation be carried out prior to designing the foundation but it was completed ignored by the designer and a shallow foundation was designed using presumptive bearing capacities which turn...
Dear all
I am the client's representative, working with a 2 story building that was initially designed to be supported on a shallow foundation, no geotechnical investigation was carried out and it was simply assumed that the ground is dense sand with an allowable bearing capacity of 100 kpa...
