(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Resource loading for multi-level structure with non-typical floors

Hi Guys,

How do you usually do this.

We will build a 3 levels podium RC structure with 2 basement, so over all 5 levels. Each level has a different wall layout plan & floor framing plan, so there will be no levels with the same quantity of material resources. Contruction programme was made, just a typical construction programme, start from lowest level going to upper levels. And also, each level was divided into bays to determine concrete pouring sequence. It is like this:

Level B2 - Zone 1, Zone 2, etc. (activities further divided into walls/columns & slabs/beams)

Level B1 - Zone 1, Zone 2, etc.

I need to put material resources in the programme, let us say formwork, rebar and concrete. I refer to the BQ but in the BQ it shows the quantity of each resources as a total, it says how many cubic of concrete for beams, for walls, for columns, etc.

What will be the easiest way to load resources for each activity in my programme? Do I need to really compute the quantity for each bay of each level?

It is usually easy to do this for a high-rise RC structure with typical floors. But with non-typical floors like this, with a large floor area, how to do this.

 

Thanks guys.

Ronn,

There are so many easy ways to load resources but it must comply with what is acceptable with the client/consultant.

You may need the Floor Area of every Floor Level and every Zones too.

Hi Ronn

A simple way to apply global quantities to different floor sizes is to just pro rata the quantity to the square m area of eacch level.

It is rough and ready for floor slabs but you may need to refine it for columns by number per slab.

For external walls it is relatively simple to just measure the extremity and pro rata the total.

Best regards

Most software define Material Resources as Consumable [nonrenewable] Resources, these are different from renewable resources and also different to volume of work functionalities.

If you are looking to model volume of work beware that resources are a different functionality not intended to mimic volume of work.

In Spider Project we have:

Resources are skilled human resources, equipment, services, supplies, commodities, materiel, budgets, or funds. Resources are used to perform activities in the project. There are resources of renewable and non-renewable type. Renewable resources are resources available to be used after they have already been used on activity. For example, grader, crane, worker or driver. These resources are called Resources in Spider Project.

Non-renewable resources are resources that can be used on one activity. For example, bricks, concrete, energy. These resources are called Materials in Spider Project.

Volume – field for the activity volume (set activity volume in those units that will be used to measure activity execution).

BQ quantities display Volume.

Semantics can be tricky.

If you want to model Volume of Work in software that lacks this functionality I suggest using UDF [user-defined-fields] to represent:

  • To date volume of work
  • This period volume of work
  • Prior Periods volume of work
  • Cumulative volume of work
  • Volume of work units

With the use of formulas or global change you will be able to relate volume of work to % complete though you most probably will not be able to get periods performance for individual prior periods.

Another rudimentary approach can be to use Cost Accounts for each cunrrency unit to represent one volume of work unit. Kind of lacing your right shoe with left foot on a table and right foot on the floor.

The best way is if the functionality is embedded within the software along with much added functionality as this is just the start of it.
