How to estimate the amount of work?

Question

System administration

There is a shopping complex in which several organizations operate. During the construction of this complex, a local network was laid in it. Now this network is up and running. But it is not clear how it works and what wires go where in it. Therefore, the task was to draw up a network map for this complex.
Does anyone have experience with this kind of work? By what criteria is it evaluated?

Answer 1

How to estimate the amount of work?

Just name the price for which you are ready to perform this work, this will be your price.
If you can’t estimate the amount of work, well, it’s more difficult.

• You can navigate by a similar order - but the accuracy is low +/- 500%
  
• You can make an estimate for the work - expensive and expensive, but accurate.
  
• Can be taken from the ceiling

What's the experience there? Fluke in the teeth and run around the floors putting cable routes, boxes, active and not very equipment on a piece of paper.
Moreover, it turns out that the key to the attic is at the caretaker who went on vacation yesterday, the office on the third floor is rented by some kind of muddy financial office and it is not advisable to approach closer than three meters, otherwise the guards start to get nervous, half of the equipment is under a layer of plaster - just yesterday they made repairs (10 lyams swelled greenery) well, and other interesting difficulties that should be heroically overcome.

Answer 2

Here, without incoming data, alas.
Analyzing data You have an idea how much time you will spend on this work or how much you want to earn.
Is the standard per person/hour not suitable? Negotiate a connection point.
There are downsides here and there. Either underestimate the cost of the point (spend a lot of time searching), or do the work too quickly (later on with the report a bit to justify yourself).
From experience, in 2nd, you can manage with the proper equipment quite quickly, in terms of building a draft for preparing a report, if the wiring was done correctly from the beginning without 100,500 switches somewhere in the network segment under the ceiling in the stairwell of a neighboring building.

Answer 3

If you don’t need to lay anything, and the job is just to ring the cable and draw a network map, then you simply take man-hours and multiply by the cost of an hour of your work.
For good, who did the SCS should have provided a cable magazine, where everything will be painted. Try to contact the archive, if there is one, they could not accept the object without this data.
