ACTUAL COSTS AND CAPACITY OF GASWORKS. 240. 



The works being some distance from the shopping 

 centre, an office and showroom has been rented away 

 from the works. 



The cost of works, as above, comes out remarkably close 

 to works No. i. The buildings cost more in the case of 

 the latter, because of the more difficult site as regards 

 levels, and because the provision of an office at the works 

 was made. 



The tenders. The following summary shows the varia- 

 tion in prices in such portions of the plant as were tendered 

 for: 



No. of Description Percentage Highest 



Tenders. of Plant. Above Lowest. 



4 Retort house roof 40*6 



4 Retort bench 237 



4 Condensers 34*6 



4 Livesey washer 72*6 



3 Scrubber- washer 38-5 



6 Purifiers 39 '8 



6 Gasholder 7-4 



2 Exhauster 5*5 



3 Station meter o'o 



The gasholder tenders were even closer than in the case 

 of works No. i. The station meter was a new one, and 

 the fact that the tenders were all one price may be set 

 down to the existence of a working agreement between the 

 respective makers. 



Mainlaying. The system of mains to supply the district 

 for which this works was designed is much more extensive 

 than that connected with works No. i. The excavation, 

 too, was of a more difficult nature, several hundred yards 

 of hard rock being encountered, the rocky stratum running 

 in several places quite close to the road surface. The 

 excavation in such situations costs 35. per lineal yard. 

 The costs, therefore, are higher, although the average 

 depth at which the mains are laid is about the same. 

 The following is the table of costs, the figures being inclu- 

 sive of all materials and labour :
