Hi, I received a MXD-file (ArcGis/ArcView), is there a possibility to open this file in AutoCad, as we don't have ArcView. Thanks, Karel

Hello CHPaul, Here it is common practice to install De Waal-piles (or in fact all types of screw piles with ground displacement). IMHO this is a very good method for installing piles. Not to expensive and technically very good if installed by a good pile installer. We mainly use this type of...

I work in Acad 2000LT and use RomanD. The solution with ^ before or after works (smcadman), but alt+0178 or %%174 doesn't work. Karel

Thank you for your response, SlideRuleEra. I contacted the tram company and apparently they always use the same method to deal with stray current, and we have to apply their method. So that part of the problem is solved now :-D. The first part of the problem stays however: is it really...

Hello, we are currently involved in a project where a big statue is to be constructed in concrete. (The foundation of the statue is a big plate (3m*40m*0.6m). The statue itself is in fact two semi-arcs in concrete (0.5*1.2m), total height 12m.) Now there is a tram passing next to this statue...

To Focht3: It's not a sound wall. The wall is around a place to stock sand, lime, ... (I don't know the english term). It is placed on a new area for industrial activities. The city is concerned they won't attract industry if the dust is blowing in the wind. So they obliged the firm to...

Hello, we have to design a free wall with a height of 15 m. There are no ground pressures on the wall, only the wind. At 2 m of the wall, there is a sewer (depth 2 m, radius 0.5m). The ground at the site is bad (soft clays,... in the first 6 m, then loosely packed sand for 3.5 m, then a good...

Thanks to everyone for their responses. I don't really know which kind of piezometer was used, as it was the engineer who worked here before me who ordered them. I will ask what kind of piezometer was used on Tuesday. If the pit stays dry, do I have to take the upward water pressure in...

Thank you Focht3 and BigH for your remarks. Focht3: Shallow groundwater is typical for the region. The piezometers were measured during 7 months, each week. There were seasonal variations - we measured from July untill January - the highest water level was in November (fall). The parking area...

Hello, I have a problem with the groundwater level in a stiff clay. We have to design a hospital, with a large basement. There is also an entrance for ambulances, at -3 m, with a kind of car park for the ambulances. To design this car park, we had to know the maximum groundwater level, so...

Thanks everyone. I called a local contractor and he suggested micropiles. I asked for the price, and just like VAD said, "they come with a price"! I would only need about 6, the price for the foundation of that one statue would be about 7500 euro! Greetings.

Thanks PEinc and Focht3 for your comments. The soil is sandy. The reason I thought of tubular piles is that they have a very small diameter in the first few meters (where all the cables are). The attacking forces aren't very big: the moment is about 400 kNm (hence the tension), so I...

The arc is vertical at the bottom, and describes a segment of a circle. So if you see it from the side it's something like this: __ / / / | | Greetings

Hello, I have to design the foundations for a kind of statue. The statue is in fact a semi-arc (it's about 16m high, the arc is circular with a radius of about 30m) made of steel. There are three such semi-arcs, for the foundation of two of them I have all the space I want for counterweights...
