Ok, that makes sense. Probably error where Mark mixed stats for build's 4 and 5.

I think the SBE quoted in build 4 is incorrectly stated. If these used a bigger brick it would have been a key feature identified.

What I am interested trying to assess what I'd like to phrase "Total Available Operational Hrs" on site.

Lay rates are great and interesting when assessing potential, but when commercialised, its about getting to site, getting the job done and then leaving site.

So I am trying to assess the overall trend concerning lay rates relating to the entire deploy period.

Perhaps another way to describe it, I am trying to assess the the trend of overall consistency (or reliability) rather than what is the quickest lay rate recorded or "how long it took to build walls when it was actually on site and working".

The following table is my current workings, that I'm happy to people, to verify, question, make suggestions etc

The items marked yellow are those estimated by me, that either contradict what has been reported, or I have tried to assess

		Dayton	Commercial	Day Care	Wellard 1	Wellard 2
1		Build 1	Build 2	Build 3	Build 4	Build 5
2
3	Bricks Laid	2,991	4,413	8,670	3,456	4,343
4
5	Stand Brick Equivalent	13,759	20,300	36,500	15,898	19,978
6
7	SBE to Brick Laid Conversion	4.60	4.60	4.21	4.60	4.60
8
9
10	Build Days / Time on Site		6	16	4.5
11
12	Total Build Hrs (8)	42	48	128	36	36
13
14	Lay Rate per Hr	71.21	91.94	67.73	96.00	120.64
15	SBE Rate Per Hr	327.60	422.92	285.16	441.61	554.94

Whilst we are still in testing phase (yes even with 5 builds, we a re still testing) and subject to further analysis and scrutiny of my numbers , it seems that apart from the Child care centre, there has been a pleasing trend in improvement in lay rates, once you "normalise" the builds back to "start when truck arrives and finish when truck leaves".

Re my comments in Yellow

Build 2 - assessed from FBRocks table 6 days (excluding Sat and Sun) and estimating 8 hrs days

Build 4 - I still contend the 21,780 SBE is incorrect. They have been using the same brick and so 15,898 is the more accurate number.

Build 5 - video say 29 laying hrs. Applied the same approach as Build 4 (also 29 lay hrs) and truck on site for 4 1/2 days


Plugging the above (assuming they are correct) into a model that tries to assess site profit based on today's brick lay rates ( I have heard as high a $3.00) and my estimated daily costs, my current draft model shows the following:

		Dayton	Commercial	Day Care	Wellard 1	Wellard 2
1		Build 1	Build 2	Build 3	Build 4	Build 5
2	Revenue - ( $2.00 x SBE)	$27,518	$40,600	$73,000	$31,796	$39,956
3
4	Op Costs - ($4,500 x Days)	$23,625	$27,000	$72,000	$20,250	$20,250
5
6	Site Profit	$3,893	$13,600	$1,000	$11,546	$19,706

There are a few elements not factored in the above could impact on the numbers, but based on what I have been able to assess I'm reasonably happy with overall improvement of the X in terms of both speed and reliability.
