Struct-Mast Engineers have mastered major repairs & restoration of all types of R.C.C. structure & steel structure from 1986 onward  which are found distressed or BIS recommends to strengthen to improve performance objective of the structures. Types of structures include are marine structures, bridges, residential buildings, machine foundations, overhead reservoirs. We have taken a lead in mitigating Co2 generation and offered concrete solutions to comply to sustainable means of restorations.

Industrious professionals all the time

Competence to achieve results for demanding tasks of repairs to industrial or residential structures of importance on land or under water by adopting sustainable practices at all stages of repair activities. 

Brief steps how Struct-Mast Engineers achieve sustainable means: 

Struct-Mast Engineers is far more convinced that refurbishing, strengthening and retrofitting of existing building has potentials of reducing carbon footprint.  Continuous evaluation and findings motivates Struct-Mast Engineers to concentrate on perpetual improvement in technology followed by good maintenance & followed by repair work helps to minimise energy wastage and living discomfort, but also increases the durability and longevity of a building’s fabric, yielding further long-term benefits in terms of the retention of embodied / capital carbon. Retrofit and refurbishment is also a carbon-generating activity in itself and its impact should be considered in relation to the total lifespan (whole life) of a building.  Still Struct-Mast Engineers maintains that executed maintenance and repair should be the first option sought in making existing buildings sustainable.  Further to above, well-designed and executed refurbishment and retrofit work comes with added benefits, not least the ‘sense of place’ that is maintained for the people who live, work in, or use the buildings otherwise. Here we describe below an holistic approach to retrofit and refurbishment concerning sustainability,  

Planning, design & specifications.

Shear connectors & protective coats to rrebars.

Sliding platform do not allow dust to fly

•     Plan out how the building can be improvised to become thermally and with natural light more efficient and sustainable. Plan your scaffolding which allows natural light and air movements while repair works are in progress.  The correct specification of scaffold reduces noise and dust pollution, reduces risks, enhances safe use for which Struct-Mast Engineers have designed and used moving suspended / sliding platform or sturdy "H" frame with intermediate platforms is a first step to achieve sustainable repair job. 
•    Specify lasting repairs and compatible method statement which supports durability of repaired structures.  The workmanship which is a vital component for achieving durable repairs is achieved next to perfection when suspended moving scaffold is used.  Lasting  concrete repairs lies in bonding the new material to the old material, use of acrylic bonding coat enhances bond between rendering surface and substrate, use of shear connectors or pins.  Protection to Reinforcement bars is also a vital step in the direction of lasting repairs. Apt selection of rendering material is the last link to achieve lasting repairs.  
•     Specify eco-friendly material namely cement + fly ash + super plasticizers.  

     Material conservations & selections. 

• Use of high performance concrete, fibres to reduce shrinkage, use of cement substitute products, use of alternative pipes for plumbing and drainage, use of durable paints, anti-carbonation coatings, use of composite material etc. are some of the measures Struct-Mast Engineers have successfully employed and used with commendable expertise.  The use of such material discourages over consumption of cement, steel and other precious material and uses industrial wastage otherwise would have created the dumping problems.

Use of dismantled / recycled material. 

Struct-Mast Engineers encourages use of industrail recycled material or waste materail in building construction as an alternative to virgin building material, building products by using industrial byproducts.  To list them few are coal combustion products, foundry waste, and slags, construction demolition products say brickbats and wastage of tiles for waterproofing of terraces etc. and these material has chemical and physical proerties that make them valuable resource.

Brickbats used for waterproofing

 Energy conservation & innovations

Recycling of industrial material is a rational effort to conserve energy and other resources  and reducing green hose gas emissions by managing material most efficiently thereby conserving natural resources and decreasing energy use.  

Innovations has made industrial byproducts use in the building construction more compatible has helped for environmental beneficial as it replaces non-renewable virgin material there by reduced energy consumption and pollution associated with these activities, saves land fill space.  Innovations has helped in usage of industrial waste more economical which reduces cost of construction for builders.  

Otherwise also using recycled material proves economical as it reduces cost of hauling and disposal.  At times material like coal bottom ash proves lighter than the virgin material is used as bedding material for green roof as it is lighter than any other virgin material. Tier shreds provides effective drainage around foundation compared to virgin gravel material obtained from river and puts less pressure on foundation. Green sustainable building is the practice of creating and using healthier and more resource-efficient methods of construction, renovation, operation, maintenance, and demolition.  Use of geo-synthetics and rock anchors have reduced pressure on retaining walls thereby calling for walls using less steel and concrete for the pressure being exerted on walls thereby reducing cost of construction and saving on steel and cement.

Other applications of using recycled material are: 

Roofs when covered with plants it reduces storm runoff. 

Furniture made with plastic lumber and containing fly ash

Building facade constructed out of cement substitute material.

Compound / side walks can be constructed out of recycled aggregates and recycled asphalt material. 

Ceiling tiles constructed out of recycled gypsum boards and use of fly ash.

Air cooled blast furnace slag is used to produce mineral wool for insulation. 

Rock anchors calls for saving in cost of  retaining wall

Everything of above you get them all under  single roof  !!!!

Conclusion:

The striking advantages of refurbishing & retrofitting are:

• The refurbishing will render the building more sustainable for existing use or intended use.
• Rendering buildings more energy efficient which reduces carbon emissions greater sustainable use of embodied-carbon investment (capital carbon).
• The word of caution is it proves at times costly and inconvenient.
