Heating 8. Water Services 9. Electrical The design team and any subcontractors are integrated into the contractors project organisation Figure 2. In these circumstances it is possible that the client may novate the original design team into the contractors team or retain them to oversee the contractors work. The management contractor injects additional construction expertise into the design process and organises the construction work packages.
During the construction stage the management contractor subcontracts the installation packages and manages the installation work Figure 2. The design team is extended to include a construction manager who provides up-front The building services designer's role and responsibilities 17 Figure 2. During the construction stage they manage the site. Contractors involved in the installation work are contracted directly to the client Figure 2. The design process starts with the client recognising a need for a new facility and ends when the facility is fully functional.
The variation in the building services designers' role is where they start in the process and where their involvement ends. A consultant's role on a traditional contract will require a continuous involvement from the outset of the project through to project completion. A designer's work for a contractor on a construction management contract would involve working up the construction design information and resolving plant and equipment details. Registration on the engineering council as a chartered engineer, an incorporated engineer or an engineering technician is only possible for designers who are members of a professional institution that is a nominated body of the council.
Both institutions require their membership to demonstrate professional conduct in their duties. He shall exercise his professional skill and judgement to the best of his ability and discharge his professional responsibilities with integrity. By-law 33 code of conduct for all members states: Gifts of a relatively trivial nature are not considered to be an inducement. By-law 34 additional code of conduct for corporate members states: The building services designer's role and responsibilities 19 Both institutions have disciplinary procedures for improper conduct by a member.
Improper conduct extends beyond a simple breach of the by-laws and includes broader issues such as bringing the institution into disrepute. Penalties include expulsion from the institution and loss of engineering council registration. Further reading Holt, A. Chapter 3 Design in engineering construction 3. However the extent and detail of the activities behind each stage are different with every project. There are a number of different industry formats for mapping the stages in the engineering construction process [1,2].
The stages highlighted in bold represent activities of building services designers. An overview of each stage in the design process together with its typical building services design activities and deliverables is provided below.
Proposals fail because they are not technically possible or they are technically possible but the cost or quality or time scale are not acceptable. Invariably feasibility work rather than stopping the development of a project involves evaluating numerous project options to determine the optimum solution. In this instance the design process would start at the concept design stage.

Finally, all the concept design options are evaluated to determine the best solution. Generate and develop a number of concept design options Identify health and safety hazards, carry out risk assessments and where necessary apply the hierarchy of risk control CDM regulations requirements Contribute to the project programme Interpret the affects of the proposed building fabric and where appropriate the impact of the enclosed process on the concept design, e.
Discuss issues related to the concept design options with the appropriate authorities, e. Co-ordinate and communicate with the other members of the design team, e. It is likely that further design development during scheme design will require minor revisions to the design brief. Under these circumstances the document must be updated, reissued and signed off. It is a very iterative process involving design, review, discussion and revision until the design solution is substantially complete.
Where appropriate the scheme design is value engineered to improve compatibility with the clients key success criteria. Integrate the other design team members' work into the design solution, e. Develop preliminary system schematics Carry out calculations to allow primary plant selections Generate and develop scheme layout drawings Establish the primary building services distribution routes and plant space requirements Identify health and safety hazards, carry out risk assessments and where necessary apply the hierarchy of risk control CDM regulation requirements Contribute to the project programme Review the design with all external third parties, e.
Determine the precise requirements of the applicable statutory legislation and client standards, e. Discuss with the primary plant and equipment suppliers the individual requirements of their plant, e. When detail design forms part of the designer's work only a scheme design report is required. The scheme design stage is complete when the client and project team agree the design and sign off the scheme deliverables.

Integrate the other design team members work into the design solution Develop the detail design schematic drawings Carry out detail design calculations Select all the plant and equipment associated with the building services systems Develop the detail design general arrangement layout drawings Generate and develop the detail design plantroom plan and elevation drawings Generate and develop any design standard details that apply across the building services project work Discuss with the suppliers the individual requirements of their plant and equipment and how these requirements can be integrated into the project work Establish all the building services distribution routes and plant space requirements.
Generally all the non-technical aspects of the work packages, e. The combined pack of information forms the contract documentation and is issued for tender to the contractors on the tender list. Generally, after the returned tenders are analysed the contractors that submit the best tenders are invited for a tender interview. Subject to client agreement the design process then moves to the next stage and the successful contractor is awarded the contract. The designer assists the contractor in developing the design.
Communicate and co-ordinate any design changes with the other members of the project team The extent of the activities at this stage are determined by the project contract and how the work packages have been let. When the work has been let as an installation contract the construction design information activities are typically those listed above. When the work has been packaged as a design and build or specialist performance subcontract, the detail design work will be carried out by the contractor or the specialist subcontractor.
Building Services Engineering
The designer reviews the contractors' installation works to ensure it meets the performance and quality requirements described in the detail design deliverables and construction design information.
It reinforces the good aspects of the design solution and highlights areas for improvement. The process is a structured method for collecting and integrating feedback into future design solutions.
This can be a little bit misleading. However, frequently the production of the construction design information and the construction stage overlap as the need to start on site to meet the overall programme becomes critical.
This is quite acceptable provided the work has been broken up into sections and the construction design information for any single section is reviewed and agreed before construction starts. If the construction activities start without the agreed construction design information then the project proceeds at risk.
If it transpires that the installation is incorrect the contractor may be entitled to claim a programme delay and associated costs. This frequently leads to a deterioration in the relationship between all the parties as programme delays and increased costs jeopardise current and future project success.
The relationship between the two models is described Table 3. Establishing who is responsible for a design failure is determined 30 Building services design methodology Table 3. Where these agreements are not clear the courts appear to start with the viewpoint that the designers are entirely responsible for the design .
The ACE conditions of engagement state the extent of the consultants' design responsibilities. The consultant is only responsible for his own design work and that of any specialist subconsultants employed by them. If any part of the design work is let to another party without the clients' consent then responsibility for the design will remain with the consultant Moresk Cleaners, Ltd.
The other aspect of design failure is the standard of design. The reasonable care and skill test is fault based, i. The law imposes a reasonable care and skill test on all professionals. This requirement is explicitly stated in the ACE conditions of engagement. This approach places the emphasis on the client to establish the consultant's negligence. However, the law tends to treat design and build contrac- Design in engineering construction 31 tors differently.
The provider of an actual building is viewed as similar to a seller of goods Viking Grain Storage, Ltd. White Installations, Ltd. If the client's brief asked for a new pharmaceutical plant that requires a manned operation Class K BS clean room and the design clearly does not meet this requirement then the designer would be liable for the design failure.
Unless during the design process they addressed the issue and agreed with all parties that a Class K standard is not a requirement. When the project works only extend to concept and scheme design i. This is inevitable as the amount of detail provided is, by its nature, substantially larger than in the other design stages.European Conformity.
The building services designer's role and responsibilities 13 The range of the regulations and approved codes of practice enabled under the HASAWA is huge. A significantly expanded companion site offers over 1, self-test questions, powerpoint slides for lecturers, and an instructors' manual, enabling the rapid generation of lectures, assignments, and tests.
The subjects of heating, air conditioning, water and gas distribution, electricity and drainage are all covered at introductory level and beyond. Factories Act is still in place however most of its content has now been repealed and replaced with new legislation under the HASAWA.
