the sub-grade (ground surface) in such a way that there will be no sinking of the road

crust in to the sub-grade under the load of traffic.

This work shall consists of laying and compacting of soling stones on prepared sub-

grade in accordance with the requirements of these specifications. The material shall

Murum: - It shall be obtained from pits, weathered, disintegrated rocks or sandy

soil, with plasticity index value not more than 6. It should preferably contain

siliceous material and natural mixture of clay of calcareous origin. The maximum

size of murum shall not be more than 20 mm.

STACKING OF MATERIALS AT SITE:

3.1 Stacking of soling stones: Ground under the stacks shall be cleaned, levelled or

dressed to a uniform slope, and all humps, depressions etc. shall be removed.

Soling stone brought to site shall be broken to the specified sizes with hammers and

while stacking all kachcha and rejected stones shall be separated out and removed

camber with granular base materials laid and compacted in accordance with the

specifications, or as directed by the Engineer-in-charge.

All soft places (clayey strata) in the sub grade should be excavated and filled in

with firmer soil and well compacted before laying soling stone. The roller shall

move over the sub-grade till the soil is evenly and densely consolidated.

Extracts of the Minutes of Meeting of the Task Force Committee on Malaria held in

the Conference Hall, Secretariat on 15-07-1997 are transcribed below:

Issue of health cards :

Under the provision of Public Health Act, the contractor/builder has to get his

labourers screened for malaria and necessary cards with photographs are issued to

them by health officer of the concerned jurisdiction. So far, over 5000 labourers are

issued cards and over 200 labourers are detected positive in this exercise. This is a

significant achievement as the labourers detected are symptomatic carriers, which

are potential reservoirs for spreading of Malaria. As a large number of labourers

are brought to this state and considering the fact that they constantly visit their

nativeplaces in Malaria endemic area in other states, the screening has to be taken

on war footing manner to cover all labourers specially in Malaria endemic areas

namely Panaji, Candolim, Calangute and Margao.

In addition to the screening done at Health Centers, the Chief Engineers (P.W.D.)

and the Director of Municipal Administration will issue instructions to their

concerned Engineers working in the above mentioned areas to identify the labour

concentrations and to inform the Health Department or other concerned Health

Centers the day fixed for the Screening of the labourers. The Surveillance Workers

of the concerned Health Department/Centre will go to the site and collect the blood

smears and subsequently the Health Officer will issue the cards after the

photographs are made available to them.

Whenever any contract/work order or N.O.C. has been issued to any party,

P.W.D. or the Municipal Authority or Panchayat should ensure that the clause

stating that “only the labourers possessing the malaria Health Card should be

employed for the work or at that construction site” should be included. For

contravening this provision, work order issued to the contractor or N.O.C. given,

will be withdrawn.
