HQM Life Cycle Cost

If you would like to target the life cycle costing credits within the Home Quality Mark (HQM) then we can help you.  We carry out HQM Life Cycle Cost (LCC) analysis which meets the requirements for the Home Quality Mark.  Our assessment is made in collaboration with the design team and will demonstrate that the selection of the most appropriate strategy has been made in order to improve design, specification, through-life maintenance and operation.

The HQM Life Cycle Cost appraisal is carried out in accordance with the ISO 15686 Buildings and Constructed Assets – Service Life Planning Part 1: General Principles; ISO 15686 Buildings and Constructed Assets – Service Life Planning Part 5: Life Cycle Costing and PD 156865 Supplement to BS ISO: 15686-5.  The appraisal meets the requirements detailed in the Home Quality Mark Technical Manual to achieve a maximum of 18 credits under the 20 Materials Life Cycle Costing of Construction Products.

In addition, we can also carry out consultancy services, and prepare a complaint report that meets the requirements to achieve a maximum of 10 credits under the 21 Durability of Construction Products.

Homeowner’s life cycle cost report

To achieve nine credits under the Materials 20 Life Cycle Costing of Construction Products we will carry out whole building HQM life cycle cost (LCC) analysis and prepare the Homeowner’s life cycle cost report.  The appraisal is prepared based on information produced at process stage 2 (equivalent to RIBA stage 2) and updated at the end of process stage 4 (equivalent to RIBA stage 4).  The appraisal will provide a prediction of cash flow for the whole building and will include the following cost items:

  • Maintenance Costs: major replacement and repairs, cleaning, minor replacements, repairs and maintenance, allowances for unscheduled repairs, replacements and maintenance, and grounds maintenance
  • Operations Costs: windows and external services, internal cleaning, specialist cleaning, external works cleaning, fuel, water and drainage, staff engaged in servicing the building, rates and other local charges, and client definable costs

The HQM Life Cycle Cost analysis will be reported over multiple cash flow scenarios, and is presented in real, and discounted costs terms.

The outputs at this stage will be a report and presented in tabular and graphical format and made available to potential purchasers, through a unique website link. It will show the summary level cash flow forecasts a summary section that highlights the most significant findings of the LCC analysis including significant planned maintenance – in an easy to interpret and understandable report.

Component level life cycle cost optimisation

To achieve the nine credit under the Materials 20 Life Cycle Costing of Construction Products we will carry out component level LCC analysis by the end of process stage 4 (equivalent to RIBA stage 4).  Again, the analysis is carried out in line with PD 156865:2008 and will include some of the following component types:

  • Envelope, e.g. cladding, windows, and/or roofing
  • Services, e.g. heat source, cooling source, and/or controls
  • Finishes, e.g. walls, floors and/or ceilings
  • External spaces, e.g. alternative hard landscaping, boundary protection.

During design development we will work with the design team and identify specification choices of systems, elements and component levels and appraise them on a life cycle cost and performance perspective and identify those alternatives that are thought to reduce the overall maintenance and operational costs to the homeowner.

The outputs at this stage will be a report sent to the client and a the creation of a unique website link – ideal to be included in marketing materials to summarise the benefits of the scheme from an LCC perspective.  It will show the results of the component level LCC analysis and this will be used to demonstrate how building and systems design/specification alternatives have been selected to minimise maintenance and operational costs to the homeowner.

21 Durability of Construction Products

In addition, we can achieve ten credits under the Materials 21 Durability of Construction Products by reporting  the estimated service life of the Integral and Finishing elements for the home(s) and communal areas.

For both the integral and finishes elements, we  identify the estimated service lives, factors that can effect the service life and typical failure modes of the key building products and report on any appropriate measures that have been designed / specified to limit these degradation effects and reduce frequent replacements, repairs and maintenance throughout the life cycle of the home.  If necessary, at post construction stage, where the design and specification measures installed differ from the proposal at design stage, we will support the design to to verify that these measures still meet the aims of the criterion.

The key is to ensure the HQM Life Cycle Cost analysis is developed in accordance with ISO 15686 Buildings and Constructed Assets – Service Life Planning Part 1: General Principles; ISO 15686 Buildings and Constructed Assets – Service Life Planning Part 5: Life Cycle Costing and PD 156865 Supplement to BS ISO: 15686-5,  and presented in easy to interpret and is useful to the potential home buyer. We are certain our service offer achieves this.
