It has been a little over two months, but over the coming weeks, many questions will still be asked around the Grenfell tragedy.
These are questions which we should not predict the answers to, given the severity fire, but questions that will need to be answered. People are already asking questions – questions asked like ‘did the residents have concerns throughout the refurbishment? Were they listened to? If not, why not?
But some questions are not being asked yet:
The emerging focus, given the Lakanal House disaster, seems to be hoping that an unfortunate individual will not be scapegoated with the blame, but instead questioning whether there is systemic failure to adequately incorporate safety and integrity in the built-environment because of overriding pressure to drive down price. We know after Lakanal House that Part B of the Fire Regulations, referring to tall buildings, was recommended for review by members of All Party Parliamentary Group on Fire Safety.
We’ve known for years that the construction cost is only 10% of the whole life cost of the built-asset so, especially where the construction owner is going to own the operation (80% of the cost) of the asset, why not invest upfront for a longer term social and economic return.
Is this why the policy is to compartmentalise fires in tall buildings, use fire/smoke safe doors and to ‘stay put’ and keep safe human life?
Scope of the Inquiry
Over 30% of respondents to the breadth and terms of the public inquiry asked that the terms of reference should cover: the design and construction of the building, its subsequent refurbishments (including the design process itself), the procurement of contractors and the qualifications and training of those making decisions. Most referred specifically to the installation of cladding and insulation, but several also referred to the installation of gas in the building.
The inquiry team have submitted their terms of reference which outline to the Prime Minister the scope of their review - within the terms of reference we are pleased to see the inclusion of:
In other words, the inquiry has full jurisdiction to report on procurement failures, if there were any that is, within Grenfell and the wider public sector procurement system.
The public sector is often under high pressure to disseminate budgets and deliver on time. It therefore chooses a design & build procurement route because it allows itself single point responsibility and absolute control over price and programme.
Contractors tell us at BESA that often tender information and drawings are basic and indicative, if lucky, but at the poorest.
This scant information is coupled with unrealistic programmes which are often set in stone at tender stage without any discussions with the ‘team’ that are eventually engaged to supply the built-asset.
However, often concerns are raised during both design and construction regarding quality, safety and integrity and those concerns are subsequently value engineered, at least once, out of the price to save money and ensure the built-asset falls within budget.
So does that mean that fundamentally the procurement system is flawed because, without regulation, it is geared towards lowest cost regardless of safety? After all, we know that all new schools do not, by default, have sprinkler systems incorporated into the design specification, and if you don’t have to have it you will remove it to reduce the price.
Our contractors inform us that rarely does even the lowest tender come within a client’s budget. This does not mean the tender is wrong, more often than not it simply proves that the client’s budget is too small and that they cannot actually afford what they want.
We’ve all seen the numerous TV shows constructing and re-constructing domestic properties, and the universal truth is that the engineering is cut to accommodate a budget which is too low to match expectations and the outturn cost is always around a third more than the budgeted cost. This brings you to a conclusion that you get what you pay for, but you have to pay for what you want.
The contract to improve insulation and replace heating and water systems in the Grenfell Tower block was supposed to be carried out by building firm Leadbitter, but the contractor said it could not do the work for less than £11.27 million. This was £1.6 million above the council’s budget.
The Kensington and Chelsea Tenant Management Organisation - which maintained the council's housing stock - put the contract back out to tender, with the winning tender carrying out the work for a price of £8.7 million, 22% less than Leadbitter’s original estimation – even though the plans did not change.
Tenders are never won on quality but on the lowest bid. Once won, the successful tenderer is then often asked, at least once, to ‘value engineer’ the price downwards, which can only:
a) save the client money by driving down cost at the expense of quality, integrity and safety
b) maximise profit by driving down construction price at a point after competitive tendering, whereby price has already been realistically driven to its lowest sustainable point
During this process the professional team usually, for lowest price reasons, provides a desktop/cursory design service leaving the specialists to back-fill their design inadequacies under a design development brief.
Portions of the project quickly emerge as falling into grey areas, that nobody has costed and which all parties thought fell within another contractor’s remit.
If budgets need to be spent, and projects completed without upfront planning, the design and integrity of the planning phase is ultimately compressed into the construction phase in order to deliver on time.
It emerged that in 2016 the London Fire Brigade had asked the council to check all tower blocks to make sure self-closing systems on fire doors were working, following an arson attack at Adair Tower in October 2015. Yet no fire safety inspections had been carried out on the block after 2015.
The Local Government Association said councils across the country were carrying out ‘urgent reviews’ of their high rises with local fire services.
Lord Porter, chair of the LGA said ‘Fire risk assessments and the construction of buildings are being reviewed and double checks are being made to ensure remedial work recommended under previous assessments have been carried out. Councils are also working closely with tenants to review and offer fire safety advice.’
But Dr Kostas Tsavdaridis, Associate Professor of Structural Engineering at the University of Leeds said builders often put appearance before safety.
‘There is a trend nowadays where architects and designers use decorative materials to make buildings more interesting and aesthetically pleasing,’ he said.
‘Although theoretically, they are fire resistant, in most cases they are high-temperature resistant instead of fire resistant. But even if they are, smoke and fire will spread through the joints and connections.’
If procurement systems were altered to cater for the integrity of the built-asset through early specialist involvement and realistic time and price expectations, corners would not be cut and the risk of mistakes would be minimised.
Contractors therefore hope that lessons will be learnt from this landmark tragedy and that the introduction of DfMA, BIM, data led whole-life procurement and the Social Value Act will play a greater part in the leadership and procurement decisions of the public sector - (represents 40% of UK construction demand) who not only built but operate the built-assets and therefore have an inarguable vested interest in the quality and integrity of the built-asset.
