CP2 - The contractors perspective
- 1. CP2 and the search to become a better client 21 September 2016 By Dominic Evans, Managing Director, Domec Ltd
- 2. New Museum of Liverpool 385k bio-diesel CHP units Two 768k natural gas CHP Two 850kW boilers A 1000kW absorption chiller A 998kW conventional compression chiller

- 5. Early findings at Plas Newydd
- 6. twid¦dle. VERB 1.twist, move, or fiddle with (something), typically in a purposeless or nervous way: "she twiddled the dials on the radio" · [More] synonyms: turn · twist · swivel · twirl · adjust · move · jiggle · [More] NOUN 1.an act of twisting or fiddling with something: "one twiddle of a button"
- 7. Ultimately the results are usually, end user dissatisfaction and/or reduced performance of the technology. In this case, far more usage of the two, small, LPG tanks Than originally planned

- 15. By including your maintenance provider at design stage as part of your team you get engineering expertise focussed on a different part of the life-cycle, this increases the chance that: Faults will be identified and rectified earlier and before the snagging period ends Focus on how the system operates once it’s installed A maintenance contractor that understands the system design from day one Relationships built over a period of time before the system goes live
- 16. Conclusions… -Issues with new technology or complex installations are common -But unless they cause a significant enough problem for the end user they often go un-resolved indefinitely. -Or worse still, the technology is by-passed completely -users push buttons and twiddle knobs if the systems don’t work as they expect them to.
Editor's Notes
- My Name is… Domec specialise in building maintenance and installations valued at <£300k. We have built a reputation on managing technically challenging buildings, buildings in remote locations and those with listings which we enable with the assistance of our building surveying business which works alongside the main business.
- We became involved in facilitating technical installations in 2011, when we worked with a CHP provider on the NML. This site was experienced some minor issues that had led to some frustration on the part of the client. CHP issues can be particularly debilitating for a building as the effect is potentially heating, cooling and power Our role here is not to understand the specifics of each specialist system but to know who and when to call in the manufacturers/specialists And also to do so before the effect of the fault becomes noticeable by the buildings occupants
- Our first experience with Water Sourced Heat Pumps came shortly after NML in the shape of YHA Lee Valley which is situated 20 miles outside of London and consists of 5 lodges heated via a SWSHP Problems with overheating and persistent pump failures had been evident since the site had been completed three years’ prior The D&B contractor responsible had gone into administration Our investigations led us to conclude that there were multiple blockages in the UFH system The rectification cost was to be in the tens of thousands of pounds plus the knock on operational and reputational damage of closing the site The end result was that we installed wall mounted electric heaters The builder had been paid, so had the consultants- the client in this situation has suffered terribly as a result of their own bright idea. For being bold and attempting to seek a sustainable solution while being an early adopter of a new technology.
- At Lee Valley there was a rumour that we had picked up from a consultant that a digger had been used to lay the screed which had caused the UFH pipwork to collapse We don’t know if this is true- but it could be The rest of the project was relatively problem free And yet the client now pays for electric wall mounted heating
- The problems at PN were immediately not catastrophic If anything they are minor irritations Reliable feedback is not that easy to obtain due to the current usage That is, it is home to a few NT staff An apartment retained as a holiday home for Lord Anglesey Coffee shop and visitor centre Visitor attraction But the manifestation of the problems were Showers not hot enough Too much heat in the building (it can’t be switched off during the summer due to the preservation of the house and artefacts within Some alarms activating on the BMS controls Some freezing of the chilled water pipework There was suspicion that some knob twiddling
- Just in case you question my technical knowledge of the word twiddling
- We see with both the YHA and NT the net effect is that the clients are paying more Not reducing their carbon footprint to the degree they were promised Therefore not freeing more opex
- Specific reasons vary greatly Some observations we have made while dealing with the aftermath of them include
- Working in Silos The client must decide on which specialist to call Once selected, the response is often confirmation that the equipment is working as per its design but the problem is likely to be another piece of equipment that needs to be working in order for it to work. Client contact next specialist The scenario repeats at the client’s cost If the problem is intermittent it becomes a battle of wills to keep traction Costs continue to increase Working in silos when diagnosing maintenance issues seems only to confirm what the problem is NOT! But working in Silos is as much of a problem during the installation too
- Commissioning When a project overruns, the last two on site are the commissioning engineer and the painters. This needs to change Not enough time or importance placed on commissioning generally Too many faults are difficult to rectify once installation is complete
- By including a pro-active maintenance company earlier, you can have a party fully focussed on matters that are currently periphery Employ the maintenance company to undertake the commissioning or to oversee those doing it This gives them the opportunity to learn the system before they take responsibility Get manufacturers training if necessary It’s worth noting that the maintenance company should be selected based on the criteria the client requires for example they might need A fast response time, making their location relevant Critical parts inventory to be kept or maintained Certain skills to be employed such as gas, f-gas, electrical competence By making the maintenance contractor responsible for measuring and capturing data, the client is more likely to understand the size of any performance gap.
- So referring back to the COP, the current recommendation is to involve the maintenance contractor following commissioning In reality its more likely to be a year after commissioning, once snagging is complete.
- I’m suggesting that, if the maintenance contractor is proactive, involve them at design stage If they know the site, they will add value Allow time and budget to allow pre-commissioning checks during construction phase Ideally employ them to undertake or oversee commissioning And continue once commissioning is complete during the snagging period and beyond
- In summery Employing your maintenance provider to undertake the tasks outlined previously, you have someone focussed on a different part of the life-cycle
- The benefits of this are clear
- Conclusions Many projects in our industry incur problems The current system whether D&B or traditional can exacerbate them The client is the one that ultimately suffers and the effect of this is likely to reduce the number of projects they encourage thereafter However- give the consultants a break- each of their schemes are a prototype and by making small changes, and bringing in a proactive maintenance contractor from an early stage, the results can be significantly improved Thankyou!
