How to Make a Reliable Winning Bid. For a construction and industrial assembly company to be financially viable, it must achieve positive economic results in the work or services it provides.
When the awarded project has its origin in a bid with errors, the project will not be profitable.
How to Estimate Indirect Man Hours. Labor that is not assigned to a specific task or process is called indirect labor.
The total indirect labor budget in a construction company is the sum of the indirect hours of each work in progress plus the indirect hours of the company in the engineering, budgeting, quality control, purchasing, sales, administration, accounting, finance, etc. departments.
In this phase, only the indirect labor of the personnel affected solely to the project being quoted is considered.
One aspect to consider is that the costs of the personnel who operate machines and vehicle drivers were already charged in the “Equipment Cost” stage.
In turn, the costs of personnel inputs categorized as indirect were also charged in the “Valuation of consumables” stage.
Indirect labor costs group together wages paid to workers who perform tasks that are not directly involved in actively converting materials into finished products or providing services.
As an example, some points to be considered in estimating indirect labor costs in a project are described:
Supervisory or support staff
The site supervision group comprises the project manager, foremen, supervisors, etc.
The work management is in charge of the work director who is the professional figure in charge of the supervision, follow-up, and control of the project.
The tasks carried out by the project manager are multiple and depending on the complexity of the project, may or may not require the help of a whole multidisciplinary team.
Major tasks of the project manager:
-To check that the resources foreseen to execute the project suffice to execute the plan of works in time and form.
-To control, through foremen and supervisors, that the works are executed according to the requirements of the plans and technical specifications and with the expected performance.
-Verify that their personnel and those of the subcontractors comply with the quality and safety standards established in the tender documents.
-Execute the certification of the work carried out, in time and form, to obtain payment.
-Verify compliance with current labor requirements.
-Verify compliance with environmental standards, etc.
General Services Department
This department ensures the timely provision of basic services for each work, for example:
-Supplying industrial water of the right quality for sanitary use, cleaning, concrete, testing, etc. We generally obtain this supply through the drilling of wells.
-Supplying drinking water for staff consumption, usually through hot and cold water dispensers.
-Supplying electrical energy (if requested by the client in the tender specifications), for example, with own or rented generators.
-Maintenance of the toilets for the employees, the best option is still the chemical toilet with washbasins.
-Maintenance of personnel transports vehicles that take workers from their lodgings to the construction site and back again.
For this purpose, we generally use minibusses with less than two years of use and speed controllers. We emphasize that the authorization for its operation is issued by the safety department.
-Maintenance of the telephone and Internet communication system.
-Labor for the maintenance of construction machinery and the supply of fuel and lubricants.
-Another daily task is the transfer and removal of all work equipment from the site.
Indirect labor costs of the surveying service
The topography specialist and his collaborators are to ensure the correct positioning and leveling of all the elements to be built or assembled.
Storerooms
They are in charge of the management of construction materials, input and consumption materials, spare parts, stock control, ordering and protection of tools, issuing reports, etc.
Administrative Department
The administrative department controls the documentation of personnel income, the number of hours worked, the completion of payments in the salary accounts, minor purchases, etc.
Autonomous groups that do not depend on construction management.
Safety and Environment Department
The safety and environment department is an autonomous group in charge of ensuring safety and environmental conservation and which audits each of the tasks carried out on-site daily in order to prevent incidents and/or accidents.
The security department is the one who decides how a work is executed safely, so the procedure with which any task is carried out must be approved by this department.
Quality Control Department
This is another autonomous department that is in charge of the following:
-Execution of tests and samples in civil works.
-Control of the traceability of the pipelines in terms of the certification of the materials and non-destructive tests.
-Checking compliance with the technical requirements indicated in the datasheets for equipment, instruments, electrical panels, and each material entering the site.
This department is autonomous and depends on the quality control of the company’s central office.
In the following post, the specific items to which the estimator assigns a defined cost are developed.

How to Estimate Input and Consumption Materials. The term consumables, or consumption materials, refers to all the auxiliary material used to carry out work, but which is not incorporated into the construction.
On the other hand, the contribution or input material, is also an auxiliary material, but it is incorporated into the construction.
How to Make a Correct Calculation of Equipment Cost.
The following diagram lists the items that make up the cost per hour of the equipment:
How to Calculate Selected Equipment Cost.
To make this calculation correctly, we must first review the following concepts:
Reliably Evaluate the Selected Equipment. To complete this stage, the estimating group with the support of specialists must define the type of equipment required for the project and then establish its costs.
