Creating a comprehensive and accurate Leistungsverzeichnis (LV), or performance specification, is crucial for any electrical installation project. This document serves as the foundation for bidding, contract negotiation, and project execution. A well-structured LV ensures clarity, minimizes misunderstandings, and ultimately contributes to a successful project completion. This article provides a detailed guide to creating an LV for electrical installations (LV Elektro erstellen), covering everything from basic principles to advanced techniques, including software recommendations and a free Excel template.
Understanding the Importance of a Well-Structured LV
The LV Elektro is more than just a list of tasks; it's a legally binding document defining the scope of work for an electrical installation. It outlines all necessary materials, labor, and services required to complete the project according to specifications. A poorly written LV can lead to:
* Cost overruns: Ambiguous descriptions can lead to disputes over the scope of work and extra charges.
* Delays: Incomplete or unclear specifications can cause delays in procurement and installation.
* Legal disputes: Vague wording can lead to disagreements and potential legal action between the client and contractor.
* Substandard workmanship: Insufficient detail can compromise quality and safety.
Therefore, mastering the art of LV Elektro erstellen is essential for both clients and contractors involved in electrical projects.
Leistungsverzeichnis erstellen: Aufbau und Anleitung leicht erklärt (Structure and Guide Simplified)
The creation of an LV follows a structured approach. A typical LV Elektro comprises the following key elements:
1. Project Overview: This section provides a general description of the project, including the location, purpose, and scope of the electrical installation. It should also include references to relevant drawings, specifications, and standards.
2. General Conditions: This section outlines general requirements, such as safety regulations, quality standards, and deadlines. It also specifies the payment terms and dispute resolution procedures.
3. Detailed Itemization: This is the core of the LV. Each item should be described clearly and unambiguously, specifying:
* Item Number: A unique identifier for each item.
* Description: A concise and precise description of the work to be performed, including materials, quantities, and quality standards. Avoid vague terms and use specific product names or manufacturer's specifications where possible.
* Unit of Measure: Specify the unit of measure (e.g., meters, pieces, hours).
* Quantity: The number of units required.
* Unit Price: The cost per unit.
* Total Price: The total cost for each item (Quantity x Unit Price).
4. Summary: This section provides a summary of the total costs, including any applicable taxes or fees.
5. Appendices: This section may include supporting documents such as drawings, specifications, and certificates.
LV für Ausschreibung & Angebot (LV for Tendering and Quotations)
When used for tendering, the LV serves as the basis for contractors to submit their bids. A clear and concise LV ensures that all bidders understand the scope of work, allowing for fair and accurate comparisons of bids. The client can then select the most competitive and qualified contractor based on the submitted offers.
