Buying new resource or keeping old one?

When you have a lot of resources (hundreds or thousands), you usually have a problem with detail analysis. Maybe, the most important question is when you have to buy new resource? I know, the new resources is prettier, but are you really need new resources. Is your old resource still good?

Using “smart” analysis in BI4Construction, you can make a right business decision. You can make smart comparison of actual costs of each resources per hour (or mileage, or…) in each cost group with cost of e.g. loan or leasing installment costs.


You can see what maintenance cost analytically for old resources is. You can also see what is you additional fuel or oil cost for old resources in comparison with new one. You have realistic cost of staying time for old resources because maintenance periods…

With all of these details, you can always make a right decision. This is usually requirement for big construction companies with lot of trucks and other machinery.

Road Construction Company Continues Business Growth by Using a New ERP Solution

With its substantial growth, the road construction and maintenance company ‘Novi Pazar – Put’ has overcome the possibilities of a functionally and technologically outdated business software they were using. Rational and efficient management of complex business processes and expensive resources created the need for the introduction of a new, modern and flexible business solution, so the company chose Microsoft Dynamics NAV, complemented with add-on solutions (NAV4Construction) developed by NPS.

I already wrote about this on my old blog post

Now, Microsoft officially released this case study on Microsoft site:

Operational work – The bid evaluation – part 9

When we have some construction position we cannot do it, we need to find subcontractor. When we engage subcontractors, we usually have a less margin. Because of that, we need to find the subcontractor with the best condition for each position. Bid evaluation in NAV4Construction is based only on the lowest cost recommendation, but we have many other information in decision process (e.g. discounts, payment methods, due date, warranty period…).

Requirement for subcontractors we fill in Requisition Worksheet, with other requirements, as items. When we fill required positions, we need to fill Quote Query No. for all positions we want to purchase from one vendor (on one quote).


From Requisition Worksheet, we can print Quote Requirement document or export requirement in Excel file.

When we get offers from potential vendors, we need to put them in Purchase Quote in NAV. We can do it manually or automatic using import from filled Excel files. We must to fill Quote Query No. on Purchase Quote Header. This is mandatory data if we want to use bid evaluation process.


We can do bid evaluation process for complete quotes, or for each construction position individually.



We need to fill Quote Query No., type as Position and Position No. We can use Best quote windows for bid evaluation, not only for position; we can use it for item, resource… Because of that, we need to choose Type option as Position. System will make ranking based on Direct Unit Cost, with many other information.


When we choose position for ordering, we need to run Apply and system will update Requisition Worksheet with data from this quote. After that, on Requisition Worksheet, we need to run Accept the action and we will get Purchase order with choosing positions.


If we want to make bid evaluation for complete offers, process is similar as individual process. We need to fill Quote Query No. and Row number. Row number is mandatory, because we cannot compare Quotes with different number of lines.


System will make ranking based on Amount including discount (sum of Direct Unit Cost with discount), with many other information. Acceptation process is the same as in the previous example.

Posting operational work (Subcontractors) – part 7

In my previous six posts I described posting of own work on projects, using different models. The base characteristics of this models is that we have our own resources and items consumption. Now, we have once more model for posting, when we use Subcontractors work. Target is the same, we need to make some contracted Construction Positions, but now we do not use own consumption.

We have two types of subcontractor’s engagement in our construction projects:

  • First, we can engage subcontractor for do some minor work on our positions. That means, we will work some part of job, and some part of job will made by subcontractors.
  • Second, we can engage subcontractors for doing complete job by position. This is very often when we work on complex construction with very vary business processes, as construction of houses, buildings, etc., because the main constructor often perform only one or two types of works and engage subcontractors for all other works.

I describe how we can planning that in Construction Position Norms in my old post about Construction Position and Norms – Cost Analyze and Bill of Quantities – (Subcontractors), but now I will describe posting of subcontractor usage.

Subcontractor’s minor engagement

This is the simply process. We get invoice from subcontractors for their part of work. For posting, we will use the standard NAV purchase documents, Purchase Order or Purchase Invoice. We will post this as our cost using G/L Account, but we must to set Job No. and Job Task No. in Purchase Lines. When we post document, we will get Job Ledger Entries with G/L Account types. Our own part of job, we will post using Job and Position Journals or using Output Orders. We will invoice position we posting using Position Journals or Output Orders, with the same quantity.

We can use this model for all planned or unplanned costs on project. NAV will be classifies our own usage as resource cost or as item cost, and all other costs as G/L Costs.

As I said, this is very simply process. Other posting method need more customization or more manual work. We choose customizations, and we make automatic model of subcontractors posting in our solution NAV4Construction.

Subcontractor’s complete position engagement

In this example, we engage subcontractors for doing complete job by position. We get invoices/certificates from them for complete position engagement as we have this job in our Bill Of Quantities.

Doesn’t meter I said is too complex process, we mad it simply. For posting, we will also use the standard NAV purchase documents, Purchase Order or Purchase Invoice, but with some customizations. We will post this using Position types (new NAV4Construction type), and we also must to set Job No. and Job Task No. in Purchase Lines.


When we post this document, we will get Job Ledger Entries with G/L Account types (G/L Account from Posting Groups) as cost, and also Position Ledger Entry with output quantity and price from BoQ, and posting type Subcontractor, as well. With only one posting, we will get complete posting process, and we can prepare our invoice to customer.

Posting operational work (resource costs/price calculation) – part 6

Using NAV4Construction, we can use specific resource cost or price models. When we post resources, we have next quantity fields:

  • Quantity – total time of resource engagement
  • Waiting time – time when resources do not make usage, because poor site organization
  • Extremely Stagnation Time – time when resources do not make usage, because force majeure
  • Effective Time – calculative field = Quantity – (Waiting time + Extremely Stagnation Time)

In NAV4Construction, we use Cost field for actual resource cost and Price form internal resource cost (transfer price for internal needs). Cost and Price are not calculate in the same way. Definition of them are placed on:

  • Quantity:
    • Cost – ‘Direct Unit Cost’ on Resource Card
    • Price – ‘Unit Price’ on Resource Card
  • Waiting time:
    • Cost – same as Quantity Cost
    • Price – ‘Standby Unit Price’ on Resource Card (using of this price depends of setup)
  • Extremely Stagnation Time:
    • Cost – no
    • Price – no

Cost Calculation

Cost Calculation is always the same. This calculation is based on resource usage and we calculate it by next pattern: Direct Unit Cost X ( Quantity – Extremely Stagnation Time )

If we want to use total quantity in calculation, we need to put ‘Extremely Stagnation Time’ blank.

Price Calculation

Price Calculation is more complex and depends of setup in ‘Res. Utilization Margin %’ field at Construction Setup. In this field we need to configure what is ‘acceptably utilization’ for us. In our example I will define that it is 70%. That means that if (Quantity-Waiting Time) is 70% or more in regard to total Quantity, this is good usage. Based on this, we have two different models of price calculation (we will use factor 0,7 instead of 70%):

Model 1: ( Quantity – Waiting Time ) >= 0,7 X Quantity

( Quantity – ( Waiting time + Extremely Stagnation Time ) ) X Unit Price

Model 1: ( Quantity – Waiting Time ) < 0,7 X Quantity

( ( Quantity – ( Waiting time + Extremely Stagnation Time ) ) X Unit Price ) + ( Waiting time X Standby Unit Price )

These Costs and Prices are the base of Construction Position cost and price calculation, based of their actual consumption.
