Engineering Services
Work Activities
Engage the services of a professional structural engineer to provide as built plans and environmental impact information for
this project. Also conduct surveys (cross-sectional and profile) of existing road, take clear and complete digital pictures to
identify existing road conditions, and road signs/markings. Identify manhole covers and other existing permanent
structures that may need to be brought into line with the final road level.
Erect barricades to control access to the job site from the public and control the worksite as a whole. Also need to ensure a
smooth traffic flow during construction. These include but not limited to temporary barriers, hazard lights, directional signs,
barricades and provide signal men as needed to assist with traffic management. Existing structures along the construction
work must be protected at all times from damage.
Demolish and dispose of the following items: The broken concrete toppings on the from the trench. Equipment Rental and
Dumping Fee for the disposal of all generated debris to an authorized dumpsite in Singapore.
Supply and backfill the excavated trench with proper backfill materials and compact them to satisfaction before laying of
the asphalt.
Supply equipment, materials & labor for milling of all existing asphalt,

Discretion is required when planning heavy exercise for acclimatized personnel.
Strenuous exercise and activity for new and un-acclimatized personnel during the first 30 days of heat
exposure.
Strenuous exercise should be curtailed for personnel with less than 12 weeks of training in hot
weather.
Physical training and exercise should be curtailed for all personnel (operational commitments
excluded).
Heat stroke likelihood is high under conditions of high exertion.
