    Contract delay

    bimr--Yes I have read the contract. In this part of the world it is a standard contract that is used on all construction projects. It doesnt go into great detail about how costs are determined when the owner causes a delay. There is a 2 sentence description in the clause that basically says the...

    Contract delay

    Ben Johnson--the contract states the contractor should be paid for costs incurred by the delay. It doesnt get much more specific than that. I have been on jobs in similar situations where the operators just sat in their trucks. Which made me wonder if there isnt some sort of case law out there...

    Contract delay

    cr1973-- I dont think it was a realistic option for the contractor to focus on another project. For the first week the contractor did as much as he could on the site but finally ran out of things to do. The contractor notified the engineer that he was running out of things to do. The engineer...

The contract clearly states he can be paid for costs for a delay caused by the owner or their representatives. Basically a rough grading contractor ran into some under ground springs and the...

    trim mat installation

    I am required to install trim mat on a steep slope to protect it from erosion and allow plant growth. The specs describe installing the mat paralell to the slope. My contractor--who is very experienced--says it makes more sense to install it perpendicular to the slope, like shingles on a roof. I...

    How to deal with springs?

    A differant firm did the geo-technical analysis of the site. They drilled 15 bore holes and the water table was 9 feet down. They drilled in early April and in this location--close to a creek--the water table fluctuates with the seasons.Nobody realized there was a spring --most thought the pond...

    Steel smooth walled culvert fixing grade.

    The cul;vert is quite deep--the highway goes thru a draw at this point and its probably 12 feet from the invert of the culvert to the top of the asphalt on the road. Its a 30 inch diameter culvert. The slope is supposed to be 1%. Right now the supposed low end of the culvert is 5 inches higher...

The grade on the culvert is flowing the wrong way.The contractor is proposing the fix the problem by digging and exposing the high end of the culvert to the road and with a welding/cutting torch...

    How to deal with springs?

    We are rough grading a large commercial site and have encountered some underground springs--water is bubbling up to the surface. The original ground in these areas was holding water and it was a slough. The contractor pumped the standing water and began removing the saturated ground with the...

    Workers are killed and injured all the time laying pipe. Trenches collapse, cables break lowering pipe into the trench, workers are run over by equipment, workers are overcome with toxic gas.It doesn't stop the industry from using the same metheods. In my province there is a governing...

    air test HDPE

    In the area I work, construction specs are written by the jurisdiction covering the area where the construction is taking place. This is a peice of infrastructure which will eventually be turned over to a town. Each city and town has their own construction specs. The city I live in has a...

    air test HDPE

    Biginch--the manufacturer of the pipe states that when testing their pipe one should refer to ASTM 2164. I contacted the manufacturer and they stated they don't recommend testing with air because of the potential danger, but they don't prohibit the use of air testing on their product. Their...

    retention pond leak

    Ok--I am going to throw an idea out there for feedback. You have a dead calm pond where water is leaking at a significant rate from a relatively small hole. Would there not be sound coming from the leak? I remember working on a job where there was a leak in a sanitary force main and a specialist...

    retention pond leak

    After periods of no rainfall, the pond water level holds at a particular elevation, approx. half way between the bottom of the pond and the desired normal water level (total depth of pond is 6m). You would think that the leak must be occurring at or above the stabilized water level. Someone...
