Building contents

Definition: What is building volume?

Construction specifications refer to the specific components and characteristics of a planned construction project that define the so-called “scope of work.” These include all agreed-upon services, materials, quality standards, and quantities specified in a construction contract or statement of work. Changes to these specifications—whether additional requirements or reductions—have a direct impact on the cost structure of the construction project.

Why is building content important?

Defining the scope of work is crucial for establishing clear expectations between the client and the contractor. A clearly defined scope of work enables:

• Transparent budgeting: A detailed breakdown of construction work allows for an accurate calculation of construction costs.
• Efficient cost control: Changes to the scope of construction work can be tracked directly in the budget.
• Legal clarity: Clearly defined construction specifications minimize disputes over work performed and work required.

Relationship between construction costs and budget figures

Any change to the scope of construction—whether it involves additional work (an increase in the planned scope) or reduced work (a decrease in the planned scope)—has a direct impact on the budget figures. These changes are typically documented as change orders or claims for additional costs.

Examples of changes to the building specifications could include:

• Additional construction work due to new legal requirements
• Changes to the quality or quantity of materials at the client's request
• Reduction of certain services due to budget constraints

How are changes to the scope of construction documented?

Changes to construction specifications are often documented in the form of addenda. Ideally, this documentation should be digital and transparent, as is possible, for example, with specialized project management software (such as PROBIS).

Typical steps in such documentation:

• Description of the change: What specific construction elements are being changed?
• Assessment of the cost impact: How will the budget figures change as a result of the change?
• Approval of changes: A formal process for confirming and incorporating changes into the project budget.

Challenges in Managing Construction Content

Project controllers, site managers, and building owners often face the following challenges:

• Complexity: Many changes happening simultaneously, making it difficult to keep track of everything.
• Time lag: Delays in recording and evaluating changes.
• Lack of transparency: Difficulty keeping track of all relevant changes and informing all stakeholders in a timely manner.

PROBIS: A Solution for Managing Construction Content

The cloud-based project management software PROBIS offers specially designed modules for the effective management of construction projects and related budget changes:

• AI-powered developer cost estimation: Instant assessment of cost implications using intelligent algorithms.
• Real-time cash flow planning: Direct adjustment of cash flow projections in response to changes in construction scope.
• Integrated amendment management: Transparent and audit-proof documentation of all amendments and changes.

PROBIS helps strategic project controllers, such as our client representative Martin Schröder, to efficiently manage complex construction projects and minimize risks arising from unclear project scope or incomplete amendment documentation.
