SummarySummary
1 Victoria Street is a new sustainable commercial office development by Stanhope and Mitsubishi in the heart of Westminster.
Wentworth were contracted to carry out a series of structural investigation works and load testing. The purpose of our works was to confirm the construction make up of main structural elements and to ascertain the condition of the concrete and reinforcement within these structures.
In total we scanned over 100no. structural elements to confirm concrete cover and geometry of the rebar.
To verify the load capacity of the floor slabs prior to brining in heavy plant such as excavators and bobcats to facilitate demolition works, Wentworth designed and implemented a series of load tests on the slabs. This type of test is carried out using a hydraulic load test system, applying a controlled load to the slabs and reordering deflection and condition of the slab throughout.
Various concrete elements were selected for a trial application of a Migrating Corrosion Inhibitor (MCI) product. Applied as a liquid form, the MCI penetrates through cementitious materials, forming a protective layer on embedded reinforcing. Wentworth applied the product and carried out corrosion rate monitoring over a six-month period. This type of system has the potential to extend the structural lifespan of buildings by 15+ years.

Key Challenges and SolutionsKey Challenges and Solutions
- Determining realistic capacities of existing structures: Alongside scanning works, it was necessary to carry out some intrusive work to fully expose rebar. This was used to confirm critical information such as bar diameter and to extract samples for lab testing.
- Justifying condition of existing concrete: As well as core drilling samples for concrete strength testing, we carried out carbonation tests and extracted dust samples for chloride and sulphate content testing. We also carried out half-cell potential and corrosion rate testing.
- Minimising the need for large-scale breakout: By utilising the latest NDT scanning equipment and analysis software we negated the need for large scale breakouts.
