Electrical for a construction cost plan

The Electrical page for a construction cost plan

Introduction

This is a simple article discussing the various elements of a construction cost-plan to attempt to articulate the best practice for construction cost-plans.

The Electrical package page is simply one page of around thirty pages that lay out, item by item, the works involved in a construction project.

What is the Electrical page for a construction cost plan ?

The Electrical page for a construction cost plan is simply the page that lists out all of the tasks that are involved in the Staircases package of a construction project.

In a typical construction costs plan there will be separate sections for the following elements (trades/work packages):

• Cover page
• Summary page
• Preliminaries
• Demolition & Strip-out
• Foundations & Drainage
• Structural steel
• Brickwork
• Roof
• Upper floors
• External Windows and Doors
• Stairs
• Mechanical (Plumbing)
• Electrical
• Fire services
• Internal studwork
• Internal blockwork
• Internal ceilings
• Skim coat
• Carpentry
• Decoration
• Floor finishes
• Kitchen
• Joinery
• Tiling
• Fixtures and fittings
• External works
• Underfloor heating
• External cladding
• Client supply items
• Contingency for unforeseen items

What is the purpose of the Electrical page

Its purpose is to summarise and total all of the various costs associated the electrical package page.

It means that the Client or any of the team members can see exactly 1) what the final total is 2) where the costs are split through the work packages.

The upper floors page should have the following:

• Logo of the company producing the construction cost plan
• Title of the page e.g. Upper floors
• Address of the project
• Date of the cost-plan
• All of the elements for the electrical package including supply and installation of the electrical works
• All of the costs for the works above
• A final total

Here is an example that we have mocked up specifically for this article:

Any other notes on the Electrical page for a construction cost plan

Electrical costs can be found easily by contacting a local electrical business.

These businesses specialise in the complete electrical packages so you can get a fixed price from them for the works.

Some of these companies will price for supplying all of the materials but if you want to provide the materials then they can provide a labour only price.

This reduces your risk for this package as you are sub-contracting the risk out to someone who can handle it better (because they do nothing but electrical and therefore know their costs a lot better than you would).

Measurement list

If you are taking off quantities for electrical works you can start by plotting out a simple take-off list.

This should follow a very logical pattern.

• Lighting
• Small power
• Conduit
• Cable trunking and tray
• Cables
• Cable and conduit in final circuits
• Switchgear and distribution boards
• Luminaries and accessories for electrical services
• Testing and commissioning of electrical services
• Identification of electrical work
• Sundry items – marking positions of holes, mortices, chases
• Temporary electrical
• Builders work
• Preparing drawings
