These errors can be avoided by using earthwork estimation. You can avoid these errors by organizing your take-offs and estimating in a structured and orderly manner. If you attempt to do Estimates at 2AM on software you don’t understand or for a site that you don’t know, you will eventually make mistakes. These are all common mistakes made by organizations.
These errors are more common when you do earthworks in Melbourne than they were back when draftsmen used scales to print. Since the widespread adoptions of PDFs and Cad, we have all been exposed. This can occur when an inexperienced or inattentive engineer creates the Drawing. Most common errors I have seen are when the Drawing is copied by an inattentive, inexperienced Estimator, or office clerk.
Avoiding Scale errors requires cross verification. As mentioned, this error can happen at any level. This simple error of not checking scale can happen at any level: from creation of the file to printing or on screen take-off. Sometimes it is more serious errors, such as an older plotter which produces the correct scale but displays the wrong one on the page. To confirm, you must verify and verify.
Before we proceed, it is important to notate any incorrect scale usage. Can you measure accurately at 1"=100 A digitizer can measure with an accuracy of 1/20th of an inch. This is 5 feet for a 100-scale drawing. Can the drawing be reduced to 1"=50 or 1"=30? Your digitizer will still function. Are you sure? Do you agree?
A casual computer search will show a significant numerical error. The most common error in elevation surveying is one foot. One foot is not enough to make a significant error on a major takeoff. A single error of one foot could result in the loss of significant material. The best way to confirm the topo is to check your EW cut/fill photo. Check out the stakes on the field. Ask the engineer about building corners/ Catch basins and elevation. Finish grade should be used to fill the hole. Take a photo of the hole and any stakes before you begin soil removal Melbourne. This will help you to request a change order. Either fix it or accept it.
I have already spoken about Scale and Numerical errors in drawings. Let's look at some of these errors: Plans that call for plastic pipe, when concrete pipe is needed, and drawings that were created after significant changes.
It may be possible for your company to save money by reviewing the specifications carefully. It is worth asking for the specifications if you don't have them. If you choose the wrong material or it is damaged, you may be subject to reduced payments. Materials at their worst
Visits to the site can help you reduce your liability. Site visits can also give you insight into traffic patterns and weight restrictions on nearby roads. Google Earth and Microsoft Virtual Earth can be great for keeping photos current, but are they worth the risk?
When you discover that you have forgotten something about a bid, it is difficult to not feel sick. It could have been as simple as a trailer. But it could also have been a Compaction of Fills, or an important Item.
A checklist or template can help reduce this error. It is easy to visualize the job. Remember that equipment and men are expensive. Remember that minutes are hours and Penny's make dollars. Remember to connect to existing utilities next time you forget.
Scope for work
It is essential to know your responsibilities in order to ensure that a project succeeds. Inefficient execution could result from improper assignments of tasks.
