The Contractor shall not carry on night work without such permission. If at any time it appears to the City Surveyor desirable for the work to be carried on continuously day and night, the Contractor shall so carry on the works as long as the City Surveyor may require, but no extra payment will be made to the Contractor on account of such continuous working.
Lighting and Protecting Works 22. From the commencement to the completion of the works the Contractor shall, at his own cost, provide and maintain all necessary hoardings, fences, lights and watchmen to protect and warn the public and regulate the traffic, and erect proper temporary bridges and crossings for preserving all rights of way in the street or to and between private properties to which the approach is interrupted by the execution of the work. No material shall be deposited on any foot-path without the written consent of the City Surveyor, and no deposit of any kind shall be placed so as, in the opinion of the City Surveyor, to unnecessarily obstruct any carriageway. When the excavated material cannot be deposited without causing this obstruction the Contractor shall, at his own expense, cart it away temporarily, and afterwards cart back so much of the material as is necessary to refill the excavation or trench.
The Contractor will not be allowed to stop the traffic on any street without the previous permission of the City Surveyor.
