    Design Process

    Once you have obtained the planning drawings from your architect, we start with a free initial consultation at your property, going through the architect’s proposal and your needs and specific requirements.

    Once instructed, we aim to apply the simplest, most cost-effective structural solution without compromising the architect layout and safety or stability of your building and will proceed with your project.

    Design Concept

    • Preparation of the structural design and calculations for submission to Building Control.
    • Preparation of the structural drawings in AutoCad for construction purposes and submission to the Building Control.

    Construction

    Understanding the Construction Process Clients often ask, “What steps are required before construction begins?” Here’s a detailed breakdown:

    Structural Engineers Pack

    • Includes drawings and calculations for steels and foundations.
    • Essential for Building Control sign-off, obtaining fixed costs for steels and foundations, and determining if party wall notices are necessary.
    • Fees range from £500 to £2000 for residential extensions.

    Building Inspector

    • Two options: council inspectors or independent firms.
    • Fees are generally similar, with a completion certificate provided at the end of the project.
    • We can offer competitive quotes from independent firms we trust, or you can choose your local council’s services.

    Pre-Construction Specification Document

    • Enables you to obtain like-for-like quotes from construction firms.
    • Prevents discrepancies in quotes by ensuring all elements are included.
    • Ensures your budget covers the entire project, preventing mid-build cost increases.

    The Specification Document Process

    Contract and Invoicing

    • The project starts with signing a JCT contract.
    • Our building team begins work, and invoices are issued every two weeks based on completed work.
    • A retention of 5% is held from each invoice, with 2.5% released at completion and the remaining 2.5% held for six months as a defects liability period.

    Flexibility During Construction

    • Allows for changes in materials or finishes without unexpected costs.
    • Adjustments are documented, and any impact on project timing is noted.
