The remaining part of the boiler house at Didcot A Power Station is set to be demolished using explosives.
Site owner RWE said that a “controlled explosive demolition” was the safest way to bring down the remaining structure and allow rescue work to progress.
The demolition will be carried out in such a way that the structure falls away from the current debris pile.
RWE said: “The recovery work can only be completed safely once the unstable standing structure has been brought down.
“Having explored other manual options, our experts have made it clear that the quickest and safest way to bring the building down is by controlled explosive demolition.”
In a statement, Coleman & Company said: ”This proposal has come from those overseeing the operation - the police, HSE and RWE. Our work on site is very much focused on the recovery of our missing men.”
Emergency services revealed last month that they will have to search through 17,000 tonnes of material to find three Coleman & Company employees missing since the February disaster.
The recovery team has been working around the clock on a section of the debris pile that has been designated as safe, and which is furthest away from the remaining structure of the boiler house.
Part of the boiler house collapsed just after 4pm on 23 February.
Christopher Huxtable, 34, from Swansea, Ken Cresswell, 57, and John Shaw, 61, both from Rotherham, have been identified as the three missing men. Michael Collings, 53, from Cleveland, was found dead following the collapse.
