A complex construction project requires several trades, specific plans, a fluctuating specification and a large amount of materials. Each scope needs to be thoroughly examined by the estimators to ensure they are bidding on the right scope of work. But big projects can pose calculation problems, and there is a risk of quantities being missed. Hence, there is a need to have a structured estimating process to organize the project information, review the costs, and be consistent with the whole bidding process.
Estimators require an organized process to organize complex information of a project. It should link drawings, quantities, labour rates, material rates, assemblies and bid information. Construction cost estimating software incorporates these elements into a single streamlined process. The project’s scope can be affected by the changes made to the project requirements, and the relevant costs are updated accordingly. This allows for better transparency of costs and ensures that key estimating data is easily accessible for expert review.
What Makes a Construction Project Complex?
The complexity of a project typically depends on the size, scope, design and participants in the project. The renovation may be straightforward and require a few trades and a few materials. Dozens of scopes and thousands of line items can be part of a commercial development.
All requirements need to be taken into consideration by the estimator before making a solid estimate. Additionally, they must monitor changes during the estimating process.
Multiple Trades and Work Packages
Many projects have multiple trades involved in the work. These can include electrical, plumbing, HVAC, concrete, roofing, flooring, framing and site work.
The pricing and labour requirement vary for each trade. There is a need to carefully organize each scope of work for the estimator. Work packages are clearer and easier to review quantities and identify missing costs.
Large estimates are also easier to navigate through because of trade-specific organisation. Costs may be separated by division, location, phase or work package. This brings a better link between project scope and the estimated cost.
Large Quantities of Materials and Labor
Extensive calculations for material and labour are needed in large projects. Estimators can be required to make thousands of measurements off of construction drawings.
Materials may be concrete, steel, lumber, fixtures & finishes, piping or electrical items. Labor calculations can include crew sizes, production rates, working times and trade-specific rates.
It is more difficult to handle manual calculations when the project size increases. Thus, structured digital estimating can minimise the repetitive calculations and organise huge amounts of cost data.
Frequent Design and Scope Changes
As a construction project nears the bidding process, the construction drawings can change. Plans can be revised by architects/engineers following review or coordination meetings. The quantities, labor, materials and subcontractor scopes can be impacted by each revision. Estimators need to be aware of these changes prior to submitting a final bid.
This can be structured by drawing comparisons with features. Digital take-off platforms can even help to compare plans and find those parts that need further review. This way, you will be less likely to miss out on crucial changes in scope.
How Does Construction Cost Estimating Software Manage Complex Projects?
Construction cost estimating software organises drawings, takeoff quantities, labor, material, pricing, assemblies, revisions, and bid information to manage complex projects. The estimator can then take a look at these components in an organized workflow.
Typically starts with project documents. Estimators upload drawings and structure these by the project. They proceed to do quantity takeoffs and apply costs to what they have taken off.This workflow is intended to make the connection between the project drawings and final estimate. It also provides an accurate picture for estimators on the influence of each quantity on total costs.
Organizing Project Drawings and Documents
This can include a hundred and even hundreds of drawings and supporting documents for complex projects. These documents can encompass architecture, structure, mechanical, electrical, plumbing and civil areas. Estimators must have an organized way of organizing a document if they want to locate the information during the quick process. Digital estimating platforms allow for the ability to group drawings by discipline, phase, area and/or drawing number.
This organisation also makes it simpler to see which revisions are being made. Estimators can determine which version of the drawing is being used prior to measuring quantities. This means that they can avoid the risk of relying on legacy project information.
Performing Digital Quantity Takeoffs
A digital quantity takeoff converts the information found in a drawing into measurable quantities of a project. Lengths, areas, counts and volume are directly measured from digital plans by estimators. For instance, when framing, an estimator could measure wall lengths, or when finishing, the floor area. The resulting quantities can then relate to pertinent cost data.
There are also 3D- or BIM-based workflows available at some platforms. These functionalities are able to retrieve information from a digital building model if the building project offers the necessary information. The use of digital takeoff tools may eliminate repetitive measurement tasks. But estimating is still required to be cross-checked with drawings and specifications.
Connecting Quantities With Material and Labor Costs
Once estimators have calculated quantities, they require accurate input costs. This estimate may vary due to material costs, labor costs, equipment costs, and waste allowance. There is a structured estimating system that can link measured quantities to unit cost. For example, in the case of a quantity that has been measured, an estimator may have a price for a material. The extended cost of the system can be then calculated.
The amount of labour can be based on production rates or a set of labour. Estimators can also break down labor and material costs to provide more detailed reporting. But it’s also a matter of current pricing. Actual costs may vary due to regional price changes, supplier changes, project conditions and market fluctuations. Even after obtaining a quote, it’s critical to have it reviewed by a professional.
How Does It Handle Multiple Cost Categories?
A complex estimate includes more than material and labor costs. Estimators may also need to account for equipment, subcontractors, overhead, taxes, contingencies, and profit.
Material Costs
The price of materials may vary from product to product, quantity to quantity, supplier to supplier, location to location and market to market. Estimators require detailed pricing records for the various broad groups of materials. A structured estimate can be broken down into trade or work packages. This makes it simpler to view the quantities and recognize any surprising price changes. There is also a need to consider waste allowances. Allowances may vary, depending on the project and installation technique.
Labor Costs
Labor costs are dependent on the number of man-hours needed and their productivity. Labour can be estimated on a unit, hourly, crew or work package basis. Large work is usually done at varying rates of pay between trades. Wages and productivity may also vary by geographic area. It provides the estimator with more visibility into costs by separating labour from materials. It also makes things easier for subsequent reviews.
Equipment and Other Project Costs
Equipment costs may cover the price of equipment, temporary equipment, transportation and equipment charges. The cost of the subcontractors can be a significant component of the estimate.
Other project costs such as permits, insurance, overhead, taxes, and others can be considered by the estimator. It’s important that each category is clearly represented in the estimate. A detailed structure allows important costs to be shown in the cost breakdown as opposed to general line items.
Markups, Profit, and Contingency
Estimators have to separate out the direct costs of a project from business financial factors. The final bid can be impacted by overhead, profit, taxes and contingency. These values should be easily discerned in the estimate. Separating clearly makes for an easier decision-maker review of pricing assumptions.
Professional judgement is also required for contingency. It is related to the risk of the project, the degree of design completion, the market situation, and the requirements of the contract.
How Does It Handle Different Trades and Scopes?
Construction cost estimating software can group various trades into separate assemblies, cost codes, scopes and work packages. A concrete scope needs other assemblies than an electrical scope. There can be variations in labor costs and material types for plumbing projects.
Estimators may organise these areas in any format they choose but need to keep them in one project estimate. This helps in having increased visibility on big projects. There is also a trade-specific organisation to aid in subcontractor coordination. The estimators can look at each scope individually prior to adding the costs together to create the overall project estimate.
How Does It Manage Design Revisions and Change Orders?
Design changes can be an estimating challenge. Several quantities and costs may be impacted by even minor drawing changes.
Comparing Different Plan Versions
When working with drawings, the estimator must be able to recognize changes between old and new drawings. This review can be more systematic, with the help of digital comparison features. The estimator could focus on areas which have changed rather than having to look at each drawing independently again. But professional judgement is still required with regard to design changes.
Updating Estimates After Scope Changes
Estimators can then revise quantities and costs for the project with a revision that changes project scope. This is easier when there is a structured estimate, as the individual line items will be organized.The estimator can see the impacted work package and can update the values of this work package. This method will minimize the amount of unnecessary changes throughout unrelated sections of the estimate.
Tracking Change-Related Costs
Change orders may impact material, labor, equipment and subcontractor expenses. If necessary for project procedures, the various costs should be tracked separately by the estimator. When records are clear, it is easier to establish a history of changes to estimates. This information can be helpful when reviewing projects and for cost discussions.
Can Construction Estimating Software Handle Large Project Data?
Construction cost estimating software can group massive amounts of line items using cost codes, assemblies, templates and structured estimate categories. There can be thousands of individual cost entries within large projects. Those entries are easier to search and review using a consistent database structure.
Another benefit of reusable templates is that they can also help establish uniformity in projects of a similar nature. Estimators are able to set up common assemblies and cost structures and tweak project-specific values.
Another layer of organization can be given in the form of reports. Teams can check out quantities, costs, labor, materials and more without having to traverse each line item. But software does not ensure accurate estimates. The output is dependent on the data and assumptions, drawings, specifications and professional review.
How Does It Improve Collaboration Between Estimating Teams?
In complex projects, there may be a number of people taking part in the estimating process. Estimators can collaborate with the project manager, subcontractors, purchasing and company management. A centralized estimating environment enables team members to have access to the same project information. Users can also share revisions, comments, reports, and bid information on the platform, depending on it.
The structure can help to diminish the possibilities of confusion among various versions of estimates. This is also an easier system of reviewing project costs. Cloud-based systems can offer extra access to various sites. However, there is a place for team-wide roles and responsibilities to be clear when editing, reviewing and approving estimates.
How Does Construction Cost Estimating Software Handle Bid Preparation?
When the estimate is at the review stage, the estimator will be required to prepare the final bid. This process isn’t simply a matter of summing up the costs of each individual.
Reviewing the Complete Estimate
Estimators should check quantities, material cost, labor cost, subcontractor cost, overhead and profit, contingencies, etc. They will also have to look for missing scopes and abnormal cost values. A final review can be used to find inconsistencies before it goes to the client.
Creating Client-Ready Proposals
The final estimate may be incorporated in a formal proposal. As part of the proposal, the pricing, scope, exclusions, assumptions and commercial terms may be included.
With a structured estimating workflow, you can more easily wrangle these elements. The estimator will then be able to give the project costs in a more understandable manner.
Maintaining a Clear Audit Trail
There may be a number of changes to complex bids. Keeping track of those changes provides an important “audit trail. Previous values, revised quantities, scope changes and pricing changes can be recorded on the record. It is helpful for teams to look back on the final bid when developing.
What Should Contractors Look for in Estimating Software?
Software should be assessed according to the size of the project, the trade needs, the estimating process and data needs of the contractor.
Important features include:
- Digital takeoff capabilities
- Material and labor cost databases
- Trade-specific assemblies
- Drawing revision comparison
- Cost-code organization
- Change-order management
- Custom estimate templates
- Bid and proposal generation
- Reporting and exports
- Collaboration features
- BIM or 3D integration where relevant
- Accounting or project-management integrations
The platform should be the right one that fits the contractor’s workflow. For a small contractor, a simpler system might be necessary. More advanced project organization and integrations might be needed for large commercial teams.
What Are the Limits of Construction Cost Estimating Software?
While technology can handle calculations and display information, it still can’t do the job of an expert’s estimating sense. The job of the estimator is not yet over as they still have drawings, specification, site conditions and contractual requirements to interpret.It is also important to regularly review cost databases. The prices of materials and labor are subject to fluctuations from region to region and market to market.
Incomplete takeoff information can be the result of poor drawings. Some specifications may need human interpretation, especially in the case of complex specifications. For this reason, it is crucial that estimators check any automated calculation before bidding on a project. They should also make a note of significant assumptions and test out unique cost values
Conclusion
For complex projects, quantities must be accurate, costs must be organized, scope management must be carefully, and there must be consistent bid reviews. These are all incorporated into a coherent process with construction cost estimating software. It can break down big estimates, monitor revisions, arrange several trades and keep on the costs record. All this is subject to professional judgement, however. Drawings, pricing, assumptions, and project requirements should be checked by estimators prior to submitting bids. The right technology and experience with reviewing equals a more uniform method for estimating complex construction projects.
FAQs
Can construction estimating software be used for large projects?
Yes. Today’s estimating software allows to manage many drawings, takeoffs, cost items, assemblies, and project data. But choosing software is dependent on the project size and estimating needs.
What does estimating software do when there are multiple trades?
Estimators are able to break out costs by trade, division, cost code, assembly, phase, and work package. This arrangement ensures that various scope are separated with each other but also allotted in the project estimate.
