We talk to Peter Woolliscroft, head of construction at NHS Estates who calls for building services engineers to show clients the way forward.

The NHS is the UK鈥檚 largest construction client, and will continue to be so for years to come. But it doesn鈥檛 present a single face to the industry. Different NHS Trusts work in very diverse ways when it comes to procurement of new buildings and refurbishment work.

Peter Woolliscroft, head of construction for NHS Estates, believes that in some cases, Trusts have demonstrated that the NHS can be a very good client: 鈥淭he NHS client is becoming a very sophisticated client to the construction industry in general. Because the industry itself is becoming more sophisticated in its innovation and bringing to the client base a far better and more cost-effective way of doing what it does than it used to do. A lot of this has been driven out of Latham and Egan and initiatives such as this, some of it is due to natural evolution to be honest.鈥

However, even Woolliscroft would agree that this is the NHS at its best. 鈥淭he NHS client rarely has the opportunity to rise to those levels of sophistication because they have got an operational job in running hospitals and managing the interface between the new work and the existing maintenance work.鈥 This though, is where building services can move to the fore. With client attention focused on whole life running costs, building services is well placed to offer expert advice.

鈥淎round 25% to 30% of hospitals鈥 revenue budget goes on maintaining the asset base,鈥 explains Woolliscroft. 鈥淎nd of that probably 60% is put into building services of one sort or another. It may be higher in other cases. It seems to me that future hospitals will need to have very high quality life cycle regime to make sure they are getting value for money.鈥

For Woolliscroft, value for money isn鈥檛 simply achieved through specification of efficient products. Nor does it mean that each area of the building is efficient in its own right, but that the whole achieves synergy. 鈥淚鈥檓 not saying anything that others haven鈥檛 said. Why I am saying it is that we are now beginning to recognise this within the Health Service. We need the building services side of the construction industry to get off its backside and respond to that. Stop doing things traditionally; stop engaging with government clients using traditional piping or wiring methods just because somewhere along the line there is a standard that somebody pulled out of a bottom drawer which mentioned these techniques.鈥

Woolliscroft is passionate about engaging with new methods of construction. He understands though, that the NHS Trusts aren鈥檛 all eager to try these things out. 鈥淐hallenge the traditional methods. Bring innovation to the table for the client. Challenge the client to justify the old ways of doing things. Raise the bar with the client all the time. The client will require educating; will require a high level of sophisticated security.鈥

New methods include modularisation, standardisation in design and greater use of IT to aid team collaboration. 鈥淚 am looking for the building services industry to take that leap of faith into modularisation, into standardisation of their plant and equipment into making an industry into a profession. Consultants know that most hospitals are similar. It鈥檚 very rare to have a unique set of circumstances in a hospital environment, it doesn鈥檛 work that way. So why do they redesign things over and over again? Why do architects design toilets over and over again?鈥

It is vital in this vision of hospital design that all parts of the construction team have their say, including the suppliers, whom Woolliscroft views as vital to the process.

鈥淲e have to recognise that the real innovation comes from the specialist suppliers not the designers. The designers are becoming more conceptual, leaving the precise detail to those that make the products to fit the bill. If it were possible (which it isn鈥檛, but may be one day) to standardise the range of products required in hospital buildings, manufacturers would have confidence to produce them. These products would absolutely meet the needs of the service rather than being the compromise that we often have now. That would be a real step forward.鈥

The partnering approach is central to Woolliscroft鈥檚 vision of how healthcare procurement should be. ProCure 21 is in place for five years, and in spite of recent rumours about the future of NHS Estates, the programme will run its course.

鈥淲e are looking for lean construction and modularised solutions which require plant and equipment to be assembled off-site defect free, fully guaranteed. We want this delivered to site with quick fix connections onto the minimum amount of infrastructure to make it up. Couple with that some easy and rapid withdrawal of that plant as and when replacement is required or increased capacity. This would involve the planners, architects and the building services consultants.鈥 Use of IT is seen as a major part of achieving better co-operation (see box below for more on Woolliscroft鈥檚 vision)

So what are the hurdles to achieving this ideal of hospital procurement? Many of those working on these projects would say that the NHS as a client is as focused on first costs as any other, and just as likely to avoid the partnering approach.

Wooliscroft says: 鈥淭he reason we can鈥檛 achieve this is because of the government鈥檚 philosophy of passing decision making to the lowest level. I don鈥檛 have a problem with that, but we need to address this. What needs to happen is that the building services industry comes to the client with an approach, rather than expecting the client to initiate this. The NHS can鈥檛 do it because we are all individual hospitals with individual needs at different times. But they aren鈥檛 unique no matter that they think they are!鈥

Convincing clients to take the partnering route offered by ProCure 21, as well as adopting methods such as prefabrication, requires education and a way to cut down the risks to all concerned.

Woolliscroft points to services such as Compassure which can offer insurance for the whole project. The ProCure 21 process also offers ways to identify and hence reduce the risks inherent in any construction project.

鈥淲e have spent the last 12 months developing a risk analysis tool. It takes the collaborative team formed by the client through the early stages of the project so all project risks can be seen by all parties. They collaborate in providing solutions to those risks. This is standard stuff, but often it doesn鈥檛 get done.

鈥淐urrently we have about 150 risks in our databank. These can be offered to the new client 鈥 and they can add to them if they want. It鈥檚 all web-based and the team works through the list to identify show stopper risks and sort out who can deal with them. Profiles are drawn on a spider diagram to show where tolerances lie in terms of which risks are greatest.鈥

But the other block to making a success of new methods is cultural. This problem lies with the client and the industry. But the client must not be allowed to resort to 鈥榦ld ways鈥 of thinking. Woolliscroft would also like to see an accreditation scheme for engineers working in the healthcare sector, which would give the client more confidence in taking advice.

From Peter Woolliscroft鈥檚 point of view, it鈥檚 down to the construction industry to take the lead in finding new ways of bringing more efficiency to the construction process.

鈥淲e have reached 80% success using traditional procurement. Now we are biting into the 20% improvement area. That鈥檚 when the screw starts to bite. I am determined that the supply chain will operate as it should do. If it doesn鈥檛, it is stifling innovation.

鈥淟ean thinking on every aspect of what we do is the key. If there was a great big chunk we could take out, someone would have seen it by now. Small cost savings may not add up to a hill of beans, but if you have a lot of hills, that adds up to a mountain.鈥

The future of IT in construction

Peter Woolliscroft, head of construction for NHS Estates, believes that the potential influence of IT on construction cannot be underestimated. He looks forward to a time when hospital buildings are essentially standardised.

"What we want is a system which recognises what you are laying out, for example an operating theatre. The system goes around the world online and pulls out examples of operating theatres which are judged best in class. You don't have to start from scratch; you choose from ten examples. The programme then offers a materials list, and prices the products as well."

Woolliscroft admits this may sound 'barking mad', but he points out that the technology is with us today.

"Our designers need to realise they don't have all the solutions. It is impossible for engineers to know what every manufacturer in the world is producing which might solve their problems. We have to tap into an industrial Google search. It's as clear as day 鈥 if you are a manufacturer, and you don't have a website these days, you aren't much of a manufacturer."

Good design is important, but building a hospital isn't about creating some exemplar project 鈥 it's about building a hospital. "I want to know as a citizen that they haven鈥檛 wasted my taxes and that when I go to hospital I am going to get the right treatment.

Hospitals should be hospitals when you open the doors. Outside, they can look however you want. The architect's flair and imagination are used in areas which are not clinical. We should not have every architect designing toilets every time."
