Material Logistics Plans
Material Logistics Plans
A tool to manage all materials from project conception through to demobilisation and completion.
Key aspects:Setting objectives and KPIs for
efficient material useMinimisation of materials through
attention to specifications, delivery & storage, handling & use, disposal
Identifying lessons learnt and best practice.

• Any location City centre - urban - rural
How can material logistics help?
• Efficient construction• Reduced transport and associated CO2• Reduced productivity loss• Improved health & safety• Reduced damaged by:
Weather Bad storage conditions Unnecessary movements Poor handling
Strategies
• Just-in-time• On site logistics specialists• Construction consolidation centres• Off-site manufacture• 4th party logistics• On-site marketplaces• IT solutions
Traditional transport to site
Site
• Many separate deliveries• Un-coordinated arrivals • Risk of congestion on site and at gates• Many half empty lorries or …• Consignments too large• High stock levels on site• Empty return journeys• High traffic flow - high CO2
Construction Consolidation Centres CCC
Site
Concrete, steelwork, very large items, and full vehicle loads when required, go directly to site
• Contractors deliver to CCC
• Mixed loads from CCC• Daily deliveries - JIT• Logistics operator runs
the CCC• Transport to site • On site handling• Waste removed on
return journeys• Bulked up, compacted
etc at the CCC
Off site manufacturing OSM
• Controlled manufacturing environment
• Standardisation• Consistent quality• Shorter time on site• Design freeze• Packaging• Transport and Travel• Reduced cost and risk
WRAP case studiesSpecific case studies examples developed by WRAP looking at:
Volumetric methods – CAD CAM software helps reduce waste <0.6% Pre-fabrication: Pods – post production waste <1%
Pre-cast concrete – Bison have reduced waste to landfill <1% using their system
Timber frame - <2% waste sent to landfill
Light Steel Frame – materials requirements down 5% and wastage reduced from 12% to <1%

Reverse LogisticsWAS620
Efficient use of vehicles visiting site – promoting better waste management
Materials arrive on site in delivery vehicles, are dropped off, and the vehicle leaves empty
Waste vehicles arrive on site empty and leave full with waste
The reverse logistics concept
A logistics operation that seeks to avoid the empty journeys, and promote the take-back of un-used and wasted materials could have a range of environmental benefits
The concept
Take-back schemes are becoming more common offerings to UK construction sites
There is a real opportunity here to:
Promote the take-back of unused / waste product and packaging by delivery vehicles
Reduce vehicle movements and mileages associated with material supply and waste management
Reduce the environmental impact of construction
The Reverse Logistics ModelExcel based model compares current against potential
The model reports the results in terms of:
The proportions of waste, recyclate and back-hauled material
The costs of material purchase, waste management and back-hauling
The number of miles travelled for delivery and waste travelled
The associated carbon footprint
Current Case Study – North Staffs Hospital (Laing O’Rourke)
