DAM ALLIED WORKS











Construction of parapet involves laying of concrete in three stages namely ( i ) kerb, ( ii ) pillars

and wall panels and ( iii ) coping. While concrete laying cycle can be matched with production

cycle for kerb and coping, the laying cycle will be very slow for pillars and wall panels in view of

thin sections with reinforcement. Considering the laying time for pillars and wall panels at twice

the production time the average cycle time will be about 1.5 times the production cycle time.

Average cycle time for laying concrete ( 4.50 x 1.5 ) : 6.75 min


Output of CC for 59 mixes ( 59 x 50 / 330 ) : 8.9 cum

As the computed daily output of 8.9 cum is close to one span quantity of 8.7 cum consider the

daily output at 8.7 cum for rate analysis.

2. Requirement of materials:Cement for mix with 1 % wastage ( 8.7 x 330 x 1.01 ) : 2900 kg

Cement for incidental works @ 5 kg / cum ( 8.7 x 5 ) : 43.5 kg

For wall panels ( 10x2x3x0.80 + 2x2x0.45x0.80 + 2x0.15x0.80 ) : 49.68 sqm

For wall coping( 0.45 x 3 x 10 + 0.45 x 0.45 x 2 + 2 x 0.35 x 0.15 ) : 14.01 sqm

For pillar coping ( 12 x 4 x 0.35 x 0.15 ) : 2.52 sqm

Total ( say ) : 95.00 sqm

Scaffolding / supports assumed at 15 percent of cost of shuttering.

Cycle time for batching / mixing / unloading 1 mix : 4.50 minConstruction of parapet involves laying of concrete in three stages namely ( i ) kerb, ( ii ) pillars

and wall panels and ( iii ) coping. While concrete laying cycle can be matched with production

cycle for kerb and coping, the laying cycle will be very slow for pillars and wall panels in view of

thin sections with reinforcement. For ornamental parapet the laying cycle time will be more than

solid parapet in view of openings in wall panels. Considering the laying cycle time for pillars and

wall panels with openings 3 times the production cycle time the average cycle time will be about

1.8 times the production cycle time.
