State of the Industry Opinion
About:
Architects
- Many recently qualified Architects don’t understand or have never done
- Physics of buildings
- Science of materials
- Building construction
- Environmental know-how
- Crunching of numbers
- Architectural Education seems to focuses on philosophical BS, and fantasy graphics over any building know-how
- Are oblivious to the real world of construction
- Architectural Profession is sidelined by the industry through its lack of competency
- RIBA Education and ARB accreditation of Architectural courses has a strangle hold on Syllabus
- RIBA Sustainable Futures need to kick some ass to change the syllabus to embrace Climate Crisis
- Brian Murphy learned more at ONC and HNC Construction than in Architecture
- Computer programmes were non-existent then.
- Manual Number crunching
- U Value calculation
- Condensation check (static only)
- Construction methods
- Materials
- Architects can rarely brief the other consultants in sustainable approaches to be adopted
- Engineers with calculations can run rings round them
- Use BREEAM or (previously) Code for Sustainable Homes and (in Scotland) EcoHomes
- These are tick-box approaches to sustainability
- Where the design team do not need to know about sustainability
- They just get advised at the end what their score is
Engineers
- Are focused on the number crunching of structural and services engineering
- Work with Environmental Assessment Method (EAM) focus on carbon or energy efficiency drives
- Need more guidance on the environmental opportunities
- Use standard non-job specific text specifications including all non-environmental options
- This approach permits use of environmental choices but does not require them
Structural Engineers
- Know about low carbon cement but steer away from the slow set and strengthening
- Seem not to appreciate the use of blended cements can act like OPC with low carbon content
- Seem not to realise a switch to low carbon cement can significantly reduce the impact of construction
- BREEAM or carbon counting seems to be having an effect in driving the use of cement substitutes
- The cost of cement compared to substitutes makes switching easy
Services Engineers
- Services Engineers read the journals about novel approaches to:
- Low energy lighting, lighting controls,
- Sustainable drainage,
- Water saving appliances and valves,
- Smart meters and smart or intelligent buildings,
- But we still see many dumb solutions born out of:
- Some knowledge applied badly,
- Fear of health and safety,
- Resulting in wasteful practices and higher energy consumption
Specifiers
- Standard readymade specifications are the norm,
- Reliant upon the drawing annotation or schedules to point at the specification clauses relevant to the project.
- Standard specification quite often:
- Permit the use of recycled aggregates or OPC replacement
- But do not require their use,
- Unless the Engineer is proactive in requesting them,
- Industry norm will be adopted for familiarity, simplicity and piece of mind.
- Never involved in policing the specification
QS & Cost controllers
- Habitually focus on low initial cost based on pricing guides
- Ignore or exclude possibility of client’s aspirations for environmental or low running costs
- No interest in investing well in competent buildings
- Set artificially low cost plans which sets in motion a ‘race to the bottom’
- Start Value Engineering exercises (posh for cost cutting) even before going to tender
- Compromise between what we design and what we build with:
- Cost cutting,
- Value engineering
- (Looking at more than one item at a time and finding cheaper overall solutions)
- Usually cost cutting in disguise
- Permitting Substitution for cheaper (worse)
Contractors
Negatives:
- Construction Industry Effectively bankrupt and still trading (after ‘dead men standing’)
- Suicidal tendering for work
- Starting the ‘race to the bottom’
- Reliance on fighting claims for more money later
- Strangle hold the sub-contractors
- Force Dutch bargaining to lower their prices below realistic levels
- Force inadequate time programmes on sub-contractors
- Preventing skilled tradesmen applying their skills and care
- Force cutting corners
- Force incompetent building
- Disasters like Grenfell
- Refuse to pay subcontractor’s invoices for 30-60-90 or longer days
- Financial strangle hold down to staff pay cheques
- Mental stress build up everywhere
- Bogged down with paperwork
- Don’t co-ordinate sub-contractors let them work it out themselves
- Don’t supervise works
- Don’t Snag the works leaving that to the Architects
- Substitutions
- (Often replacing a good product with a worse one or a different performing product),
- Surreptitious substitution or otherwise,
- With low initial cost as the primary criteria for their success.
- Ignoring the success of the building
Positives?
- Kier Construction have been substituting CLT in place of concrete frame school building
- Primarily in school buildings to speed up the construction time to meet the school schedule
Constructors
- Further degradation of ambitions occurs on site through lack of communication from the design team,
- Lack of understanding by site agents and managers leading to substitution and poor supervision
- Poor supervision, lack of care or lack of knowledge of new systems or methods
- Language barriers resulting in no or broken communication
- Leading to misguided ambition and poor workmanship
GBE’s Response
- It’s time for change,
- Green Building Encyclopaedia (GBE) is the second of BrianSpecMan’s contributions
- GBE is about developing a more detailed and joined up understanding of environmental design principles
- Generating detailed ‘Healthy Environmental Appropriate Effective, Resourceful and Competent Construction’ rules
- Even some ready-made potential solutions with guidance on choice.
