Temporary Works in Construction For Discussion:- A large proportion of individuals on construction sites these days do not know what "Temporary Works" (as defined in BS 5975) refers to and I have repeated discussions with individuals on site regarding this. Any where the word "Temporary" appears, individuals assume it is "Temporary Works" such as:- - Temporary Water Supplies - Temporary Electrical Supplies - Temporary Doors - Temporary Buildings etc. I also have repeated discussions with Permanent Works Designers on this and explain BS 5975 defines what "Temporary Works" are in construction as they do not know of BS 5975 or "Temporary Works". How can this be rectified ? Temporary Works Forum (TWf)
Looking at the comments on this post that is here for discussion, would it be fair to say that:- -one of the first key steps is suitable recognition of Temporary Works in all engineering courses. All designers and engineers need to understand and appreciate all Engineering that is required for the Construction of the Permanent Works Design. -all designers and engineers that are serious about their development and learning and wanting to be the best they can be, should actively seek out suitable site experience and their employers should support this. - no Permanent Works design should be accepted with out the PW Designer supplying a clear and safe construction sequence for their design highlighting all additional Engineering required for the Construction of their Permanent Works Design. Education is something I have attempted to assist with with the book I complied and I am not saying it is perfect but I gave up my free time to try and help this situation with no benefit to myself and with no support from anyone or any industry bodies except for the individuals who gave up their time to review the document. My suggestion to use “Construction Engineering” is to hopefully make this subject easier to describe and understand.
Further to this discussion if a system existed to:- - Track the design from the orginal Permanent Works Design to the issue to the contractor for construction - Which clearly shows the Permanent Works Designers assumed and proposed construction sequence of their design - Which clearly highlights the risks from the Permanent Designer that could not be designed out and that the Contractor on site needs to be aware of to manage on site - This system tracks and manages any queries from the contractor on site back to the Permanent Works Designers which would be through the Prinicipal Designer - the amount of design changes, RFI’s / TQs, etc. could be assessed. - if the design changes,etc are excessive and demonstrate the PWD was not suitable for construction the Permanant Works Designers could have a penalty in their proposed pay for the design - if not excessive the PWD could be awarded a bonus payment Do you think this would help matters ?
Also consideration needs to shown to where TW can become or has the potential to become part of the permanent works design?
As Ian Horton-Plant stated, there is no such thing as temporary electrics. The term may be used as something ‘not’ permanent, but the electrical installation still needs to comply with BS:7671 wiring regs and because it’s ‘temp’ and on a construction site, it needs more stringent and frequent inspections being a construction site. If it’s potable water supply for a construction site welfare….. people are drinking it…. So not a temp ‘ water supply’ still needs chlorination etc…. The M&E / MEP, which ever term suitable…. The installations need to be correct for their environment and compliant.
There's a lot of talk about designing temporary works...but very little about the constructability of structures. I'm seeing more and more structures being designed and approved for construction without full attention being paid to how that structure is likely to be built and where it is to be built. The less consideration for constructability, the more complicated the temporary works will likely be. Rather than questioning the need to teach engineers how to design temporary works, should we be considering giving designers construction experience?
I've had this a lot, too. I think your attempt to change the title is worthy as I've sometimes had other "temporary" stuff thrown at me. I think you mentioned in your book that Temporary Works is the civil / structural response to temporary situations. Other disciplines such as Electrical have their own response to temporary situations. One way of arguing your case might be to understand some requirements from, say, the Wiring Regs and throw it back at people asking "this is what BS 7671 says, what is your company doing about it? Who is your SAP? How are you managing isolations etc? How are you managing electrical inspections and testing? You need a competent person managing this and I'm just a dirty civil engineer!" I spoke to several electrical and building services engineers over the years and they certainly didn't want me anywhere near their stuff and for good reason as I can't even be trusted to wire a plug.
Better training at university. Better training within companies.....client contracting AND designer organisations. Overall awareness as per the TWF training course wouldn't go amis. Reference is made in CDM 2015 but many people still don't fully understand that but that's a whole other discussion.
A strong collaboration between the Temporary Works Designer and the Permanent Works Designer is crucial for defining the performance criteria of temporary works and for the management of the Design Risk Register. For example, when constructing a temporary shaft for Cut and Cover Tunnels, the design decision regarding whether the temporary shaft wall is considered part of the permanent construction will significantly affect the sizing of the shaft and the quality aspects of the SOE like positional tolerances and water tightness..etc
I wish to include an additional reference from BSI - PAS 8811:2017, which pertains to temporary works and outlines the procedures for major infrastructure clients as a code of practice. Tunnelling is classified within the heavy construction sector. The Tunnel Boring Machine (TBM), categorized as a temporary work, plays a crucial role in ensuring the quality of the permanent lining during construction.

3moI am not one for copying and sharing codes of conduct but through this discussion, CDM and enforcement of CDM has been mentioned and also ICE reviews to highlight requirements so I had a look and thought this may be of interest for the discussion:- Engineering Council ethical statement refers to :- Respect for life, law, the environment and public good Engineering professionals have a duty to obey all applicable laws and regulations and give due weight to facts, published standards and guidance and the wider public interest. They should: • hold paramount the health and safety of others and draw attention to hazards ICE code of conduct refers to :- Rule 3: All members shall have full regard for the public interest, particularly in relation to matters of health and safety, and in relation to the well-being of future generations. The manner in which members can fulfil this Rule includes, but is not limited to, the following: · Take all reasonable steps to protect the health and safety of members of the public and of those engaged in the project. This covers the whole life of a project during construction, operation, maintenance and decommissioning.
