All Construction KPIs
Pan-industry data on • Profitability • Productivity • Safety • Predictability: – Cost and time • Construction cost • Construction time • Client satisfaction: – Product and service • Defects
Typical KPI Chart

How do KPIs work?
Performance against each KPI is compared against graphs showing industry norms. A benchmark score of 50% indicates that your performance is equal to that of 50% of the industry

Headline KPIs
Environment KPIs
Impact on the Environment – Product & Construction Process Energy Use (Designed) – Product Energy Use – Construction Process Mains Water Use (Designed) – Product Mains Water Use – Construction Process
Respect for People KPIs: KPIs for People Management issues
Employee satisfaction Staff turnover Sickness Absence Safety Working hours Qualifications and skills Equality and Diversity Training Pay Investors in People
Why measure KPIs?
Remember the KPIs themselves are only the starting point. KPIs are a tool for continuous improvement
All stages Planning Design Corporate Social Responsibility
Include Corporate Social Responsibility within business strategy and policy documents
Economic sustainabilit y
For large-scale housing, mixed use and civi ls projects, report on relevant factors in regional or local economic strategy, and how development wil l promote vi ability.
Use the Design Quality Indicators, to deve lop appropriate levels of functionality and flexibility.
Appraise options using whole life costing.
Design for accessibility.
Construction process Finished product Planning Design
Use the Key Performance Indicators Maximise opportunities for local businesses, labour an d training.
Consider maintenance, operational (energy, water etc) and staff costs. Use feedback measure and tools (eg Post Occupancy Eva luation.)
See environment.
Social sustainability
Respond to regeneration impacts required in regional or local economic strategies.
See economic.
Use data from public consultations and participation.
For high density, mixed-use developments plan for high quality public space and safe public transport accessibility.
Larger schemes require affordable housing, and a mix of housing types and tenures.
Use the Design Quality Indicators, to engage everyone in the design process.
Construction process Finished product
Use the Respect for People Indicators Register sites with the Considerate Constructors Scheme and use CSCS.
Maximise opportunities for local businesses, labour an d training Consider staff costs, eg maximising satisfaction and productivity throug h a healthy environment.
See environment.
Encourag e community use of buildings, through the Design Quality Indicators or as policy.
Sustainability in Constructing Excellence: Checklist
The checklist is for appropriate for consideration by all construction projects, whether large or small. Constructing Excellence encourages the construction industry to consider all aspects of sustainability (economic, social and environmental) and to guard against undermining one section for the benefit of another.
Environmental sustainability
Holistic environmental assessment tools have been developed: SPEAR, BREEAM Offices, Retail and Industrial, EcoHomes, CEEQUAL (civil engineering), Bespoke BREEAM for one-off projects, and t he Checklist for large mixed-use developments. If a de monstration project is using such a s cheme or an equivalent, it passes this section. Howeve r assessment is sometimes inappropriate, so the following checklist could be applied. The Environmental Performance Indicators (EPIs) provi de a s et of benchmarks for site and building performance that have been used on a number of demonstration projects and that Rethinking Construction has agre ed to use on a further 25 projects.
Planning
Reuse land. Treat contaminated land on-site. Reuse buildings.
Plan the footprint of the building with ecological features in mind.
Consider how bu ilding users will travel to and access the site, and facilities and amenities nearb y.
Design
Design for minimum waste of materials. Provide facilities for the minimisation and management of waste.
Protect and enhance biodive rsity using the biodiversity EPI. Ensure natural features can be easily managed and maintained.
Specify local and low envi ronmental impact materials (eg use A-rated specifi cations from the Green Guide or equ ivalent and timber from certified well-managed forests). Use the embodied energ y Envi ronmental Performance Indicator.
Optimise passive energy use (eg solar gain). Minimise energy use (eg lighting, heating/cooling, ve ntilation, insulation). Consider Combined Heat and Power and renewable energy sources. Use the operational energy EPI.
Fit sub-metering and intelligent building monitoring systems.
Specify fl exible information and communication services.
Ensure high indoor air quality through effective ventilation, and specifying materials, finishes and cleaning products with minimal harmful effects.
Specify zero ozone depletion and low NOx systems and materials.
Ensure fittings are low water vo lume. Consider rainwater and grey water recycling. Consider permeable design for hard landscaping. Use the water EPI. Fit sub-metering.
Discourage single-occupant car use, through pu blic transport and cycling provision, making the deve lopment safe and secure, provi ding showers and changing rooms.
Consider ease of operation and maintenance through commissioning time and documentation.
Consider daylighting, ventilation, humidifi cation, personal control, and space for well-being and comfort. The Design Quality Indicators consider a range of environmental criteria.
Design for flexibility or deconstruction with minimum waste.
Construction process
Manage for minimum waste, using the waste EPI. Reuse waste on-site.
Protect and enhance existing ecological features (trees, hedges, ponds etc) using the biodive rsity EPI.
Minimise air pollution (dust & fumes) and noise pollution.
Minimise water use during construction, and gua rd against pollution.
Consider transport to and from site using the transport EPI. Consider energy use through plant and site services.
Sustainability in Constructing Excellence: Checklist
Constructing Excellence: definition of sustainable construction targets (2003)
We have s et targets for each of the areas that we are measuring. To begin with, we have s et targets for the first year based on national figures achieved in 2003, and we will revi se longer term targets and milestones next year once we have information about our own performance in the region.
