Misalignments identified and corrected, including bay roof geometry

The Challenge

The client needed a measured survey and an existing drawing package for a residential property in Wimbledon Chase, including side boundaries and drainage features (manholes and SVPs), and they needed the information quickly to start work.

The initial request included coordinating access and confirming survey timings, with a preference for the surveyor to message ahead with an ETA. After the draft drawing pack was shared for review, the client identified several alignment issues between items such as the bay window plan versus elevations, the conservatory, and boundary lines.

A key technical issue was also raised around roof geometry: the bay roof was drawn incorrectly, affecting the intended overhanging eaves. With the project moving into active design and delivery, accuracy across plans, elevations, and roof layouts was critical to avoid downstream rework.

Our Solution

We arranged the measured survey with defined arrival windows and provided a direct point of contact for the site visit, supporting smooth access on the day. The survey scope included boundaries and drainage features (manholes and SVPs), so the resulting information could be used confidently for site planning and coordination.

Following issue-spotting during the client’s review, the drawings were promptly re-checked. We acknowledged the bay roof discrepancy and confirmed the technical fix: adjusting the roof plan position so it produced the intended overhanging eaves on both the main dwelling and the conservatory.

We also explained the reason for an apparent boundary misalignment on one side: the first floor and roof were wider than the ground floor due to an archway at ground level. Updated drawings were issued, and we invited further feedback to confirm everything lined through as expected.

The Process

Agreeing Scope, Fee and Friday Access

We confirmed the required outputs for an existing drawing package and the specific survey inclusions, including side boundaries and drainage items such as manholes and SVPs. We also gathered client contact details and access preferences, including the request for an on-the-way message and updated ETA.

On-Site Survey

We proposed survey dates and agreed arrival windows for the site visit. The schedule was coordinated alongside another survey on the same day, ensuring the client had clear expectations for morning attendance. We provided the surveyor’s contact details to support smooth access and communications.

Cross-Checking Before Leaving

Our surveyor attended the property and captured the measurements needed to produce the as-built drawing pack, including site context items requested in the brief. The survey data supported accurate plan production and helped ensure boundary and drainage features could be represented consistently in the drawings.

Turning Survey into Plans and Elevations

We produced the draft drawings and issued the pack for client review so any inconsistencies could be flagged early. This review stage focused on “lining through” between plans and elevations and checking key elements such as the bay window, conservatory, boundaries, and roof layout.

Draft Review and Final Handover

Following client feedback, we re-checked the drawings and corrected identified discrepancies, including the bay roof geometry to achieve the intended overhanging eaves. We clarified where building form differences explained perceived misalignments and issued an updated drawing set so the client could proceed confidently.
