OBJECTIVE:
To study and understand the various types of scaffolding, formworks, shoring
methods and techniques
UNIT I PLANNING AND SITE EQUIPMENT & PLANT FOR FORM WORK 9
At Tender stage – Development of basic system – Planning for maximum reuse –
Economical form construction – Planning examples – Crane size, effective scheduling
estimate – Recheck plan details – Detailing the forms.
Overall Planning – detail planning – Standard units – Corner units – Schedule for column
formwork – Formwork elements – Planning Crane arrangements – Site layout plan –
Transporting plant – Formwork beams – Formwork ties – Wales and ties – scaffold
frames from accessories – Vertical transport table form work.
7
UNIT II FORM MATERIALS 9
Lumber – Types – Finish – Sheathing boards working stresses – Repetitive member
stress – Plywood – Types and grades – Textured surfaces and strength – Reconstituted
wood – Steel – Aluminum Form lining materials – Hardware and fasteners – Nails in
Plywood
Concrete density – Height of discharge – Temperature – Rates of Placing – Consistency
of concrete – Live loads and wind pressure – Vibration Hydrostatic pressure and
pressure distribution – Examples – Vertical loads - Uplift on shores – Adjustment for non
standard conditions.
UNIT III DESIGN OF FORMS AND SHORES 9
Basic simplification – Beam formulas – Allowable stresses – Deflection bending lateral
stability – Shear, Bearing – Examples in wall forms – Slab forms – Beam forms – Ties,
Anchors and Hangers – Column forms – Examples in each.
Simple wood stresses – Slenderness ratio – Allowable load – Tubular steel shores
patented shores – Site Preparation, Size and spacing – Steel Tower Frames – Safety
practices – Horizontal shores shoring for multistories – More concentrated shore loads
T- heads – Tow Tier wood shores – Ellis shores – Dayton sure grip and Baker Roofs
shores – Safeway Symons shores – Beaver – advance shores Dead shore – Raking and
Flying shores.
UNIT IV FORMWORK FOR BUILDINGS 9
Location of job mill – Storage – Equipment – Footings – Wall footings – Column footings
Sloped footing forms – Curb and gutter forms – Wall forms –Prefabricated panel
systems – Giant forms curved wall forms – Column heads – Beam or girder forms –
Beam pockets – Suspended forms – Concrete joint construction – Flying system forms.
Causes of failures – Inadequate shoring inadequate bracing of members – improper
vibration – Premature stripping – Errors in design – Failure to follow codes – How
formwork affects concretes quality – ACI – Case studies – Finish of exposed concrete
design deficiencies – Safety factors – Prevention of rotation – Stripping sequence –
Advantages of reshoring.
UNIT V FORMS FOR DOMES AND TUNNELS, SLIP FORMS AND SAFETY
PRACTICES FOR SCAFFOLDS 9
Hemispherical, Parabolic, Translational typical barrel vaults, Hyperbolic Folded plates –
Shell form design considerations loads – Inserts , Anchors bolts – Building the forms-
Placing concrete – Form removed – Strength requirements – Tunnel forming
components – Curb forms invert forms – Arch forms – Concrete placement methods –
Cut and cover construction – Tolerances – Form construction – Shafts.
Slip Forms - Principles – Types – advantages – Functions of various components –
Planning – Desirable characteristics of concrete – Common problems faced – Safety in
slip forms special structures built with slip form Technique – Codal provisions - Types
of scaffolds – Putlog and independent scaffold – Single pole scaffolds – Fixing ties –
Spacing of ties plan – bracing – knots – safety net – General safety requirements –
precautions against particular hazards – Truss suspended – Gantry and system
scaffolds.
TOTAL: 45 PERIODS
