The index relates to costs ruling on the first day of each month.
NATIONAL HOUSE CONSTRUCTION COST INDEX; Up until October 2006 it was known as the National House Building Index
Oct 2000 data; The index since October, 2000, includes the first phase of an agreement following a review of rates of pay and grading structures for the Construction Industry and the first phase increase under the PPF.
April, May and June 2001; Figures revised in July 2001due to 2% PPF Revised Terms.
March 2002; The drop in the March 2002 figure is due to a decrease in the rate of PRSI from 12% to 10¾% with effect from 1 March 2002.

March 2011; The drop in the March 2011 figure is due to a 7.5% decrease in labour costs.
Methodology in producing the Index
Prior to October 2006:
The index relates solely to labour and material costs which should normally not exceed 65% of the total price of a house. It does not include items such as overheads, profit, interest charges, land development etc.
The House Building Cost Index monitors labour costs in the construction industry and the cost of building materials. It does not include items such as overheads, profit, interest charges or land development. The labour costs include insurance cover and the building material costs include V.A.T. Coverage:
The type of construction covered is a typical 3 bed-roomed, 2 level local authority house and the index is applied on a national basis.
Data Collection:
The labour costs are based on agreed labour rates, allowances etc. The building material prices are collected at the beginning of each month from the same suppliers for the same representative basket.
Calculation:
Labour and material costs for the construction of a typical 3 bed-roomed house are weighted together to produce the index.
Post October 2006:
The name change from the House Building Cost Index to the House Construction Cost Index was introduced in October 2006 when the method of assessing the materials sub-index was changed from pricing a basket of materials (representative of a typical 2 storey 3 bedroomed local authority house) to the CSO Table 3 Wholesale Price Index. The new Index does maintains continuity with the old HBCI.
The most current data is published on these sheets. Previously published data may be subject to revision. Any change from the originally published data will be highlighted by a comment on the cell in question. These comments will be maintained for at least a year after the date of the value change.
Oct 2008 data; Decrease due to a fall in the Oct Wholesale Price Index.

本指数以每月首日生效的成本为基准编制。
全国住宅建筑成本指数；2006年10月前其名称为全国住宅建造指数。

2000年10月数据：自2000年10月起，该指数纳入了建筑业薪资与薪酬结构审议后达成协议的第一阶段内容，以及薪酬保护基金（PPF）下的第一阶段涨幅。

2001年4、5、6月数据：因PPF修订条款中2%的调整，该批次数据于2001年7月进行了修订。

2002年3月数据：2002年3月1日起职业社会保险（PRSI）费率从12%下调至10¾%，导致当月指数出现下滑。
2002年4月起的指数剔除了PPF项下2002年4月1日一次性发放的相当于基本工资1%的定额补贴。

2003年4、5、6月数据：根据《国家伙伴关系协议：持续进步》，自2003年4月1日起追溯实施3%的涨幅，因此该批次数据于2003年8月进行了修订。

2006年4月与10月的指数涨幅源于《社会伙伴关系协议：迈向2016》。

2011年3月数据：当月指数下滑源于劳动力成本下降7.5%。

指数编制方法
2006年10月之前：
本指数仅涵盖劳动力与建材成本，此类成本通常占住宅总价的65%以内。本指数不包含管理费用、利润、利息支出以及土地开发等相关项目。
本住宅建造成本指数统计建筑业劳动力成本与建材成本，不包含管理费用、利润、利息支出或土地开发等项目。其中劳动力成本包含保险费用，建材成本包含增值税（VAT）。

覆盖范围：
本指数覆盖的建筑类型为典型的3居室2层地方当局住宅，应用范围为全国层面。

数据采集：
劳动力成本以双方约定的薪资标准、津贴等为基准。建材价格于每月初从同一供应商处采集，对应同一代表性建材组合。

计算方式：
对典型3居室住宅建造的劳动力与建材成本进行加权计算，最终得到本指数。

2006年10月之后：
2006年10月，本指数从“住宅建造成本指数”更名为“住宅建筑成本指数”，同时建材分项指数的编制方法从基于典型2层3居室地方当局住宅的建材组合定价，调整为采用中央统计局（CSO）表3批发价格指数。新指数与原住宅建造成本指数（HBCI）保持了连续性。
最新数据已发布于本工作表中。此前发布的数据可能会进行修订。与初始发布数据存在差异的修订内容，将在对应单元格添加注释予以标注。此类注释将在数值变更之日起至少保留一年。

2008年10月数据：当月指数下滑源于批发价格指数下跌。
