Data quality, concepts and methodology: Apartment building construction price indexes

(Table 327-0044, 2002=100, quarterly, 1988 to present)

Introduction

These indexes measure changes in contractors' selling prices of apartment building construction. The indexes relate to both general and trade contractors' work and exclude the cost of land, land assembly, design, development and real estate fees.

Characteristics

General

In conjunction with Canada Mortgage and Housing Corporation, a typical or model apartment building that had been constructed was selected and 1981 pricing was obtained. Sample items of work-in-place to be subsequently priced were taken from this model. All prices are collected directly by Statistics Canada surveyors and include costs of materials, labour, equipment, relevant federal (until 1991) and provincial taxes and contractors' overhead and profit. Value Added Taxes such as the Federal Goods and Services Tax (GST), the Quebec Sales Tax (QST) and the Harmonised Sales Tax (HST) are not included.

Frequency of pricing

Commencing in the first quarter of 1988, prices are collected quarterly for six census metropolitan areas (CMAs) and the Ontario part of the Ottawa-Gatineau CMA. In the period from 1981 to 1987 prices were collected in the first quarter of each year in Montreal, Toronto, Calgary and Vancouver. In 1986 and 1987 price movement was interpolated to establish annual figures.

Prices used

The prices for work-in-place are obtained through phone surveys with sub-contractors and general contractors, who construct apartment buildings, on the basis that they are bidding on a fixed specification and quantity under current market conditions. Prices include contractors' overheads and profit. Prices for certain materials, labour rates, rental of equipment, municipal charges and sales taxes are obtained from a variety of secondary sources; particularly for the mechanical and electrical trades.

Weight base

Weights are derived from a detailed cost analysis of a model apartment building and expressed in 2005 price levels.

Index formula

A fixed weighted formula is used at the CMA level. A Chain- Laspeyres index formula is used for the seven CMA composite levels, for which the weights are derived from building permit data for the previous three years, valued at the price levels of the fourth quarter of the last year.

Revisions

The figures of the most recently published indexes are subject to revision but all other figures are final.

Historical data

There are limited annual data for four CMAs (Montreal, Toronto, Calgary and Vancouver) relating to the first quarter of each year from 1981 to 1987 inclusive.
