How to Write Construction Specifications for Contract Documents?

When establishing specifications for construction contracts, it’s important to make sure that the criteria are consistent throughout and that they match what’s contained in other documents. If one person draughts all of the documents or, if parts are authored by others, one person carefully reviews through the entire set of documents, consistency can be improved. An inconsistency in the paperwork might lead to a large contract dispute, which can have a significant financial impact.

Creating Construction Contract Specifications

The following are some general rules for drafting specifications.The subject grouping and arrangement should be logical. These must be planned ahead of time. Each subject’s requirements should be written clearly, in a logical order, and double-checked to ensure that all areas are covered. Language and punctuation should be double-checked to ensure that there are no ambiguities. It is not appropriate to utilise legal language and phrases. The words’shall’ or’must’ (rather than’s hould’ or ‘is to’, etc.) should be used to define obligations. Quality must be explicitly defined, rather than being stated as ‘best,’ for example. Keeping to the essentials is the best way to achieve brevity. It’s not easy to write a specification that’s error-free. It’s a big help to duplicate model clauses that, by the way, are a lot of fun to write.

Many past contracts, via use and modification, have proven adequate in their wording. Model clauses can be saved as computer files and then easily reproduced and modified to fit the needs of the project at hand. It is not recommended to copy entire texts from a previous specification, as this may result in inconsistent requirements. It’s difficult to compose entirely new content, and it’ll almost probably take more than one attempt to do it right. The construction specification must clearly state to the contractor: The scope of the job to be completed The needed level of quality, type of materials, and craftsmanship The means he is obligated to use, or may not employ, to construct the works, when applicable in the first case.

It’s best to avoid repeating criteria

The first section contains an informed summary of what the contractor is expected to supply, as well as all particular factors, limits, and other considerations. The second section lays out the specific requirements. The level of detail used should be proportional to the quantity and relevance of each given type of work in relation to the overall project. Thus, where a large amount of structural concrete is to be laid, the concrete quality specification may be rather lengthy; but, if concrete is simply required as bedding or thrust blocks to a pipeline, it may be quite brief. The goal should be to create a ‘tailormade’ specification that is appropriate for the nature of the contract’s activity.It’s best to avoid repeating criteria. When requirements appear in two places, there is a risk of ambiguity or conflict.

Differences in language might produce uncertainty or dispute. There’s also the risk that a late change will change one sentence but not its repetition elsewhere. The third of the above-mentioned things requires careful attention, since there may be risks and liabilities associated in directing the contractor’s work. Some procedures, such as the requirements for handling and pouring concrete, may need to be described, although these and comparable items should be specified under the craftsmanship and materials provisions. Other method instructions should only be included if they are absolutely necessary for the design. For example, if an existing structure needs to be underpinned or shored up, the particular method employed should not be stated.

Construction Specifications

Normally, there is no need to identify a specific method, but there may be a requirement to exclude some methods, such as prohibiting the contractor from using explosives. Avoid ambiguous language like ordering the contractor to provide matters, objects, and requisites of any type,’ or’materials of any sort or description,’ etc. d or reasonably inferred from the contract.’ Similarly, the statement “all materials excavation” is ineffective. Although the drafter may believe it covers any rock encountered, it does not if the geological data provided with the contract or reasonably available to the contractor gives no evidence of rock’s existence. Definitions like those found in the Civil Engineering Standard Method of Calculation.

A contractor’s primary papers for bidding and executing a project are working drawings and specifications. Specifications are detailed written documents that accompany construction documents and explain materials and installation procedures. They explain the project to be built, augmenting drawings and becoming part of the contract, as well as material characteristics, manufacturing techniques, and installation, as well as workmanship and construction mode. They also provide information not included in the drawings, such as a description of the end outcome. Many designers struggle to create a competent set of standard building specifications, partially because it requires them to switch gears and represent design content through a different medium: writing rather than drawing. They also give the designer a boost.

Specifications for Contract Documents

Specifications should complement drawings rather than overlap or duplicate them, and they usually specify the construction quality requirements to be met on the project. They describe the technique for determining whether or not requirements have been met. Specifications are regarded legal documents since they are a vital element of the Contract Documents and should be thorough, accurate, and unambiguous. The main goals of specification writing are to specify the scope of work and to serve as a collection of instructions. The essence of specification writing is defining the scope of work. The needed quality of the product and services must be clearly conveyed to bids and the contracting party, and the completed project must meet these requirements.

Project specifications, along with drawings, bidding requirements, and other contract conditions, are now typically included in a project handbook that is distributed as part of the contract package. The writer of the specification should make sure that the requirements are compatible with the methods to be used, and that the methods chosen in one specification are compatible with those chosen in another. One of the most important functions of project specifications is to provide thorough information on the materials and methods of construction for a given construction project. They address different aspects of the project, including as general circumstances, scope of work, material quality, and craftsmanship requirements. The drawings, along with the project specifications, outline the project in great detail and clearly show how it will be built The undertaking.

Importance of Solid Specifications

In the United States and Canada, the Construction Requirements Institute (CSI) Master format is the most extensively used standard for arranging specifications for building projects. Its organisational structure is well-known. CSI is a non-profit organisation made up of architects, engineers, manufacturers’ representatives, contractors, and other interested parties who worked together to create this format. Master Format, which was enlarged from 16 to 50 divisions in 2004 as explained later in this chapter, contains its specification standards. It should be noted that CSI no longer supports the 1995 edition of the format. The CSI and Construction Specifications Canada (CSC) collaborated to create the MasterFormat 2011 Update, which replaces all earlier editions.

Due to technology and green-related practises, we’ve seen a fundamental shift in specification writing in recent years, which has had a huge impact on the construction sector and how we do business in general. Specification creation and reproduction, for example, have advanced considerably in just a few years. Master systems are now widely available in electronic form, allowing specifiers to quickly obtain drawing checklists and explanation sheets by simply loading them into their computer. Following the updating of the relevant sections, a printout with an audit trail may be created, which informs and records what has been removed and what decisions have yet to be taken. The CSI’s remarks,Many various delivery systems, products, and installation methods are used in construction projects.
