Construction projects are living systems: loud and dynamic systems with people, materials, rules and money. It is that intricacy that makes built projects satisfying, as well as what contributes to the delay, cost increase, safety and quality problems.

This article will take you through the most typical engineering issues that are encountered by teams working on construction projects currently, and why they are important to you, and how these problems are practically overcome. We will use the latest research and best practices in the industry that will enable you to implement the solutions that have been working in the industry and at the planning table.

Introduction

On the one hand, some engineering headaches are similar on small commercial fit-out projects and billion-dollar infrastructure programs. Top of the list include increasing prices and declining productivity, disjointed communication between the stakeholders, weak supply chains, shortages of skills and safety concerns. Unaddressed, such issues put risk on the line, scar margins and reputations.

The silver lining: some of them can be handled through improved prior planning, improved contracts, improved technology, and a safety-first attitude. I will unravel each challenge below and give you clear actionable remedies that you can begin implementing right away.

1. Budget increase and time slippage

THE ISSUE: The projects constantly go over-budget and take up their time. The construction productivity is years behind other industries, that is, projects tend to cost more with passage of time than projected.

According to the analyses of McKinsey, the productivity of construction has increased insignificantly, which has been leading to an increase in the cost around the world.

WHY IT OCCURS: The late design, an inability to identify risks, an optimistic schedule, misaligned contracts, and supply disruption are time and money additions.

HOW TO OVERCOME IT:

I. Front-load Risk Management: Invest in early stage risk workshops and contingency planning (not once a problem has been identified). Schedule Monte Carlo Use quantitative risk assessment (e.g., schedule Monte Carlo) on high-impact tasks.

II. Implement Digital Project Controls: The embedded cost-schedule dashboard, earned value management, and real-time reporting will mitigate surprises and allow taking corrective action sooner on time.

III. When possible use modular and off-site buildings: Prefabrication moves the work out of overcrowded locations to a controlled factory setting which lowers the on-site delays and rework.

IV. Use The Right Contract Form: Match incentives between owner, designers and contractors (e.g. target-cost contracts, gainshare / pain share models) to minimize adversarial change orders.

2. Lack Of Communication And Coordination

THE ISSUE: Inadequate interaction between design teams, contractors, subcontractors and owners causes rework, conflicts and delays.

WHY IT OCCURS: There are several stakeholders that usually operate using various pieces of information (paper, PDFs, drawings), and field teams can not be updated in good time.

HOW TO OVERCOME IT:

I. Centralize project information with BIM and common data environments. Building Information Modeling (BIM) provides all people with one coordinated digital representation to make decisions on, which aids in identifying clashes at the site before they occur. Research and industry analysis demonstrate that BIM enhances teamwork and minimizes rework in design in scenarios in which the adoption process and training are presented.

II. Unify communication standards. Friction is minimized by daily huddles, specific RFI (request for information) turnaround time and a specified change-management workflow.

III. Rely on light field collaboration tools. Markup, photos and punch lists apps receive real time feedback of the site to designers and managers – fixes can be made faster.

3. Fragility of supply chains and fluctuation in prices of materials

THE ISSUE: Schedule interruptions and budgetary problems caused by lead times, shortages, and spikes in prices of raw materials (steel, cement, timber) needed.

WHY IT OCCURS: Global supply chains are susceptible to logistic bottlenecks, geopolitics and high demand. Just in Time buying of construction makes it weak.

HOW TO OVERCOME IT:

I. Early supplier qualification and diversification. Single-source dependency should be avoided, pre-qualify the secondary vendors.

II. Price lock-in and delivery where feasible. Utilize long-lead purchasing policies and forward buying orders of risky products.

III. Make material substitution planning at the design stage. The engineering teams must find acceptable alternative materials or ways that will not affect safety or compliance.

IV. Co-ordinate logistics with suppliers. Look at procurement as a project critical path activity: include supplier lead times in the master date. Recent scholarly and business literature underscores the importance of supply-chain integration as one of the components of enhancing the delivery performance.
