Dear all, we interested in purchasing an estimating, planning/control and management software mainly for EPC projects (Overhead power transmission and distribution). Do any of you have any experience with a commercial package??

Dear all, we are building an overhead line in which the grounding design for each tower is a horizontal wire buried at a depth of 0,7m with a length from 30m to 120m for each tower leg (depends on the soil resistivity of each tower). To determine the soil resistivity the client spec refer us to...

Dear all, we are purchasing 500kV and 230kV line hardware and insulators and our client asked for a Power Arc Test according to their specs. In their specs they define the AC Circuit, number of tests, symmetric current, durations of each tests and the asymmetric ratio. The supplier of the...

Dear all, we are building and overhead power line with guided towers. Because the type soil (see attached file), the foundations for the guides are drilled as per designed. The client had approved the designed, however yesterday, they decided to reject it based on the assumption that they cannot...

Dear all, recently on a doubled circuit (four conductors per phase) 500kV Overhead transmission line that we are building, the splices are been made on the tensioner. Unfortunately, our crew cut the cable 100m longer that it was supposed to and after sagging, the splices were located 22m from...

Dear all I would like to create tasks on my schedule that represents payment events. The Idea is to have a rough estimated of a cashflow allowing me to easily simulate different scenarios. So far, I thought about using a cost baseline for cost and a second baseline for revenue. Does anybody...

Dear all, I work for a construction company which is defining all managing processes. Nowadays , we define the beginning of a project by the signing of the contract which leaves the preparation of the tender out of the project scope (mostly EPC projects). What I would like to hear is whether or...

Yes, by default the plscadd will sag as tight as it cans without violating the % of uts in the autosagging critiria. When you work with conductors, the sag is given by many variables (tension, temperature, creep effect, etc) and I imagine that some of these parameter could be treated the same...

I believe that after you have created the conductor (ADSS) file you just have to define the stringing criteria which has to do with the permitted % of UTS of the conductor under a particular weather condition. If I remember correctly, the NESC will define which are the % allowed and the PLSCADD...

Dear Red, I understand that it can not exist a "planned" with out a baseline. Just create a baseline and when the project plan is approved, create a new baseline Regards

You are right, I didn’t read carefully your question. Check the status date and if it is still not working properly check the field named AC (Actual Cost) and compare that one to the ACWP .

For EVA remember to use physical % comp. and configure msp to calculate eva using this value

Try creating a baseline YJO

Dear Pullpen 1. I have done many projects with live/baseline and it usually works fine. My sugestion would be: • As TTFN said, take your time planning, use only physical predecessor (don’t use resources availability as a predecessor) • Use PERT and DELPHY to estimate times • Because of the...

Thanks SG, actually I am just measuring at the stub the resistance to ground. When I mentioned that this is a new project I meant that I will be measuring the resistance during the civil works, prior to the stringing of the conductors/shield wire. What I was thinking is that I would like to have...

Dear all, I need to purchase a megger to measure the resistance to earth on overhead transmission lines. Eventhough initially will be used for a new project I was interested in buyin a HF megger. Do anyone have any suggestions on a model appropriate for my needs? Thanks YJO

Dear collegues, We are building an overhead powerline (500kV) and recently we started to experiment some problems with the conductor (ACSR). Basically, the conductor is showing a separation between the lairs of aluminum (kind of an bird cage effect) before it reaches the tensioner. To me its...

Dear all I have one task with an "x" amount of hours, the resource that is capable of performing the task is available 1 unit at the begining and after a certain date, 5 units. I define this availability on the resource sheet, however I am not able to get the autolevelling function to do the...

You may be able to adequate rule NESC 235 to phase to phase clearance

You need to stablish priorities prior to the levelling, (1000 is most important, 1 is less important)
