Cost Factors in Formance Panels
Cost Factors in Formance Panels
Formance Panels are a cost-efficient method of building when compared to timber framing and batts, particularly when energy costs are taken into account. In addition, Formance Panels are strong, straight, warm, dry and healthy with low long-term energy costs.
Formance quotes will include:
- supply of all wall and roof panels cut to length and shape as required by the design
Formance quotes will not include:
- timber required for splines and lintels. A Schedule of quantities and sizes required will be provided to the builder to source the correct quantities of these items.
- structural steel lintels and fixings are to be supplied by the builder.
- freight cost from factory to site. An estimated cost will be provided.
To assist with an efficient on site operation the panel layout drawings should be reviewed, checked and, if they do not look correct, they should be queried and reviewed with the architect or designer.
Electrical and plumbing service supply and reticulation should be pre-planned and shown on the panel layout drawings. Planning meetings with the plumber and electrician must be held prior to these trades starting their on-site installations to ensure maximum efficiency for the whole installation.
All consumables, except nails and bolts, will be quoted by Maxilam in Levin (firstname.lastname@example.org , phone 06 366007).
Delivery will be by hiab. A flat and level platform should be prepared as close to the building as possible. Keep the panels protected from the weather. Ensure sufficient space is available for the delivery truck, forklift and crane.
Mobile scaffolding is generally required. Type and height will be dictated by the site.
Fixed scaffolding is usually only required on a two storey building.
The bottom plate set-out and fixings should carried out be the builder. This should include all the requirements of the bracing plan. Check overall dimensions and the building for square. If the panel layout drawings are followed ,then the allowed tolerance of 3mm between panels will cater for any manufacturing or set-out variance. By marking all panel positions on the bottom plate s part of the bottom plate set-out, this will allow for any panel creep to be addressed early.
Start panel erection in a corner and the walls then become mostly self-bracing. The roof geometry will dictate any propping requirements. Pre-plan and erect any necessary propping to minimize labour and crane time.
If a mobile crane is required, an allowance of 30 minutes per panel is found to be sufficient. Plus crane travelling time.
To take delivery, erect, completely finish and tidy up, a 4-man team will erect 15 panels in an average day. Additional labour should be allowed for depending on the degree of difficulty and site conditions.
