DIFFERENCES BETWEEN BESMM 3 & 4 NIQS BESMM 4 TRAINING WORKSHOP 6-7th APRIL, 2016

COMPARISON of measurement documents BESMM3 & CESMM3 CESMM4 & BESMM 4 Adopted the format of SMM7 of 9 columns Work sections retained same identity in both building and Civil/Industrial Engineering eg D- Groundwork, E- Concrete work Integration of NRM 2 and CESMM 4 but retained the 9 columns in BESMM 3 Work sections identified separately for both building/civil, industrial engineering e.g 2A-2Z; 2AA-2AB; 2F-2H concrete Adopts CESMM4 for civil/industrial engineering works

Metalwork/timber G-Metalwork/Timberwork 2N-Structural metalwork/miscellaneous Metalwork Miscellaneous metalwork, scaffolding structural metalwork, timber, all lumped together under the above Extensive integration of CESMM 4 (current) Structural metalwork/ miscellaneous metalwork together Fabrication as members (main Bridges, subsidiary and framing) Bridge bearing materials-Elastometric and propriety added. Bridge bearing 6 items differentiated.

Piling ancillaries D 75 BESMM 3 2S BESMM 4 Group together. Measured work items pre-boring, extensions, cutting off tops, etc. including disposal, delays Each of the measured work has 7 or 8 items of piles ancillaries to be measured. These exclude disposal and delays. Disposal is deemed to be included with the piling works.

Piling ancillaries D 75 BESMM 3 2S BESMM 4 The cross sectional area, mass, sectional modulus etc. were not given or specify Pile test did not provide for type of test to be done The cross sectional area, mass, sectional modulus etc. their range were given or specify Pile test provide 5 types of test to be carried
